spindle cell cancer

spindle cell cancer

Combined chemoradiation therapy frequently shows similar findings but with a greater degree of mucosal and submucosal glandular atypia and distortion. Immunohistochemically, tumor cells in SpCC often express epithelial and mesenchymal markers. However, if SpCC occurs intraosseously,366 its distinction from sarcomas with a spindle cell appearance may be extremely difficult or even impossible if immunohistochemistry or electron microscopy fail to reveal epithelial characteristics (Fig. Spindle cell carcinomas occur at every head and neck subsite but have a predilection for the oral cavity and larynx. Spindle Cell Carcinoma Spindle cell carcinoma (SpCC), also referred to as sarcomatoid carcinoma, is a biphasic tumor composed of conventional SCC and malignant spindle cells. Some tumours are made up almost entirely of spindle cells. Nodular fasciitis may exhibit mitotic figures, but they are not atypical; moreover, no cellular pleomorphism is present. The only known cause of … In a few reported cases of carcinosarcoma of the thymus, the spindle cell component has displayed features of rhabdomyoblastic differentiation by immunohistochemistry or electron microscopy.65 The majority of cases, however, are composed of poorly differentiated carcinomatous elements admixed with a poorly differentiated (vimentin-only) spindle cell sarcomatous component. A diagnosis of a SpCC is based on demonstration of an invasive or in situ SCC and a malignant spindle cell component. The type of tumour depends on the location in the body and the way the cells look when examined under the microscope. The carcinomatous component may be present only at the base of the polyp and is often overgrown by the more exuberant spindle cell component. There is no definite known cause for this type of tumour, but it can sometimes occur as … Because the term "metaplastic carcinoma" comprises a heterogeneous group of tumors, it has been difficult to reliably predict biologic potential or to determine optimal therapy. The shape of the cancer cells is spindle and so it is named spindle cell sarcoma. Spindle cell sarcoma is a rare malignant (cancerous) tumour which can develop in the bone or soft tissue. Gastrointestinal spindle cell tumors can arise from the muscularis propria of the esophagus and extend predominantly into the posterior mediastinum, rather than into the esophageal lumen (Fig. Cytokeratin expression can be demonstrated in spindle cells in 40%–85% of cases. Several other terminologies have also been used including polypoid squamous cell carcinoma, … Only two cases had detectable HPV RNA, only one of which was strongly p16-positive. It is more common in areas that have been exposed to the sun, although this is not always the case. In some studies, 50% to 60% of affected patients are alive after 5 years.1, Adrián Mariño-Enríquez MD, PhD, Jason L. Hornick MD, PhD, in Practical Soft Tissue Pathology: a Diagnostic Approach (Second Edition), 2019. Spindle cell carcinoma. The converse situation, granulation tissue mimicking SpCC, may occur after ionizing-radiation exposure. It is a very aggressive form of cancer, and patients who are diagnosed generally do not live more than five years. For example, any mitotic activity in a smooth muscle neoplasm of deep soft tissue or in a neurofibroma is usually indicative of a malignant diagnosis, whereas this is not true for myofibroblastic or “fibrohistiocytic” lesions. The classic radiologic appearance has been referred to as a cupola sign.17, 19 Histologically, these tumors reveal a biphasic growth pattern, showing areas of carcinoma (well, moderately, or poorly differentiated) with areas of malignant undifferentiated spindle cells. There is only one published work in the literature that studied HPV in these lesions. Pulmonary Spindle Cell Carcinoma is classified as a sarcomatoid carcinoma of lung, which are aggressive tumors, along-with pleomorphic carcinoma, giant cell carcinoma, carcinosarcoma, and pulmonary blastoma; Spindle Cell Carcinoma of Lung is a type of sarcomatoid carcinoma that can develop anywhere in the lung. They most commonly arise in patients over the age of 40 and are extremely rare - making up just 2-5% of all primary bone cancer cases. Spindle cell carcinoma of the breast is a rare sub-type of breast cancer, that falls within the general category of metaplastic breast carcinoma. Moreover, foci of osteoblastic or chondroblastic differentiation (both benign and malignant) sometimes are observed.355,359,362,363 There may be sharp borders between SCC areas and the spindle cell component, but a gradual transition, with SCC cells “dropping off” from the epithelial nests or overlying squamous epithelium into the pleomorphic spindle cell areas, frequently may also be observed.352,359, Ultrastructural examination may reveal epithelial features such as desmosomes or tonofilaments in the spindle cells.356,359 More easy to employ is immunohistochemistry, by which expression of epithelial markers can be analyzed (Fig. Within the oral cavity, frequently involved sites include the tongue, gingiva/alveolar mucosa, buccal mucosa, floor of the mouth, and lip. The most common type of normal spindle cell is called a fibroblast. (a) Polypoid and ulcerated tumor consisting of sheets of malignant spindle cells with moderate amounts of eosinophilic cytoplasm. We use cookies to help provide and enhance our service and tailor content and ads. Spindle cell carcinomas are characterized by a proliferation of spindle cells with varying degrees of atypia and mitotic activity, often exhibiting transitions with areas displaying the features of conventional spindle cell thymoma. Infiltrative borders, tumor necrosis, atypical or hyperchromatic nuclei, and mitotic activity may or may not be indicative of malignancy, and they should be interpreted according to the line of differentiation and other features of the lesion. Exact symptoms will depend on where the cancer has spread. Polypoid glottic tumors appeared to have the most favorable prognosis (90% 3-year survival rate), whereas patients with supraglottic, hypopharyngeal, sinonasal, and oral SpCCs did poorly regardless of their tumor's gross appearance. A negative reaction for S100 protein and HMB45 helps to distinguish SpCC from malignant melanoma. Tumors purely composed of pleomorphic spindle cells without any expression of keratin have been observed to recur as conventional SCC and serve to illustrate the profound divergence in differentiation morphologically as well as immunohistochemically shown by SCC cells.357. The pleomorphic spindle cells usually form the bulk of the lesion; they are arranged in fascicles or whorls. A spindle cell sarcoma is a soft tissue sarcoma whose cells exhibit a spindle shape, with an elongated body that is wider … SAUL SUSTER, CESAR A. MORAN, in Modern Surgical Pathology (Second Edition), 2009. Macroscopically, SpCC can present either as an exophytic, polypoid lesion or as a flat, ulcerated tumor. SETTLE: This is a highly cellular biphasic tumor showing primitive thymus histology, characterized by an admixture of spindle-shaped cells that merge with epithelial cells (Figure 24-86). Those which are situated right next to an important artery or organ system may be inoperable. Spindle cell (sarcomatoid) carcinoma of the breast is a rare variant of breast cancer that has been classified under the broad rubric of metaplastic carcinoma. As a result, they are usually treated differently from small round cell sarcomas, and have different biological characteristics than those tumors and sarcomas with epithelioid morphology. Keywords: Spindle-cell carcinoma, Second primary tumor, Synchronous cancer I. The name of these often ends in “sarcoma.” Occasionally, the spindle cells of the tumor may “stream off”or drop off from the overlying squamous epithelium. This Spindle Cell Cancer Support Mix, is given in conjunction with a powerful antioxidant extract derived from the bark of the Maritime Pine Tree, (Maritime Pine Bark Extract). These tumours can be either benign (non-cancerous) or malignant (cancerous). Treatment of SpCC is the same as for conventional SCC. Squamous differentiation may be present including keratinization and intercellular bridges. Spindle cell carcinoma is a relatively rare form of cancer. Similar to conventional SCC, there is a strong association with a history of cigarette smoking. Spindle cell carcinoma and carcinosarcoma are rare, high-grade primary thymic epithelial neoplasms characterized by a spindle cell, sarcomatoid appearance. Some of the most common varieties occur in the skin on areas which have been overexposed to the sun. Spindle Cell Squamous Cell Carcinoma (SCC) of Skin is a malignant tumor of skin that is typically seen with a higher frequency in immunosuppressed individuals. The most sensitive/reliable epithelial marker for SpCC seems to be keratin (AE1/AE3, K1) K1, K18 and EMA. Whether or not the entire mass can be removed will depend on where the tumor is located. Calcifications can be seen in the stroma. The spindle cell component usually forms the bulk of the tumor. An SpCC should not be confused with the so-called teratocarcinosarcoma.368,369 This neoplasm typically occurs in the nasal cavity and the paranasal sinuses, sites at which SpCC rarely occurs, and is characterized by an extremely diverse histologic pattern with mature and immature glands, benign squamous and malignant poorly differentiated epithelia, and rhabdomyosarcomatous, chondrosarcomatous, and neuroepithelial differentiation (Fig. Oral spindle cell carcinomas usually are treated by surgical resection, alone or combined with radiotherapy. De très nombreux exemples de phrases traduites contenant "spindle cell" – Dictionnaire français-anglais et moteur de recherche de traductions françaises. This type of carcinoma can cause a large mass, or tumor, which is generally surgically removed during the initial stages of treatment. (B) Spindle cell carcinoma with abundant edematous, myxoid stroma. However, spindle cell tumors can appear on the skin of a dog or cat as well, and be rather frustrating. Both were T4 tumors and had poor outcomes. Spindle cell carcinoma is a type of cancer which usually originates in the connective tissues of the body. There are really no clinical symptoms that would distinguish this particular cancer from other types of breast cancers. These tumors can have a CT and endoscopic appearance that more closely resembles that of a posterior mediastinal mass than an esophageal wall mass.85–87 Esophageal spindle cell neoplasms are usually c-kit–negative leiomyomas, although occasionally they can be c-kit–positive gastrointestinal stromal tumors (GISTs).85,86 These tumors have an EUS appearance of a hypoechoic mass with some internal signal and occasional acoustic enhancement, which sometimes makes them difficult to distinguish from cysts.86 Because GISTs are highly metabolically active, they can often be diagnosed and followed with PET scans.88 Although leiomyomas generally are PET-negative tumors, there have been reports of PET-positive esophageal or posterior mediastinal leiomyomas.87 EUS FNA can be used to diagnose both posterior mediastinal leiomyomas and GISTs and can be considered when the distinction between a cyst and a GIST is uncertain. Microscopic examination exhibits a proliferation of invasive spindle cells, typically accompanied by a squamous epithelial component (consisting of dysplastic surface epithelium, carcinoma in situ, or conventional invasive squamous cell carcinoma). Prognosis of the laryngeal SpCC is controversial, but it seems to be favorable for patients with no history of radiation, glottic location and polypoid appearance of the tumor. Oscar Lopez‐Nunez, Lea F. Surrey, Rita Alaggio, Karen J. Fritchie, Ivy John, Novel PPP1CB‐ALK fusion in spindle cell tumor defined by S100 and CD34 coexpression and distinctive stromal and perivascular hyalinization, Genes, Chromosomes and Cancer, 10.1002/gcc.22844, 59, 8, (495-499), (2020). Spindle cell sarcomas of the bone are often found in the arms, legs and pelvis. Therefore, in these cases, a diagnosis of SpCC does not apply. Sclerotic fibrosis abruptly separates the spindle cell component into a lobular pattern. How well they work will depend on whether or not the disease has moved out of the initial area. A: Spindle cell carcinoma is a kind of connective tissue cancer where the cells are spindle-shaped. {"}Spindle cell{"} is a descriptive phrase that denotes the cellular shape of many of the sarcomas encountered in the adult population. Pieter J. Slootweg, Mary Richardson, in Diagnostic Surgical Pathology of the Head and Neck (Second Edition), 2009, Spindle cell carcinoma (SpCC), also called pseudosarcoma, sarcomatoid SCC, “collision” tumor, or sarcomatoid carcinoma, is a biphasic tumor composed of SCC cells and pleomorphic spindle-shaped cells.352 Since its original description, several theories have been forwarded regarding the significance of the pleomorphic cells.353,354 These cells represent either non-neoplastic bizarre stromal areas, metaplastically altered SCC cells, or cells of a separate mesenchymal neoplasm that forms a collision tumor with the SCC component, for which the term carcinosarcoma is employed. If such tumors are less cellular, they may mimic benign reactive lesions. After radiation exposure, bizarre granulation tissue–containing pleomorphic spindle cells and atypical mitotic figures may develop that should not be misinterpreted as tumor recurrences displaying the histomorphology of SpCC277; this was discussed previously in the section on laryngeal SCC. De très nombreux exemples de phrases traduites contenant "spindle cell carcinoma" – Dictionnaire français-anglais et moteur de recherche de traductions françaises. The tumor can arise anywhere within the upper aerodigestive tract, with a predilection for the larynx and oral cavity. It is important to note the often abrupt transition between the two components of this tumor. Sun exposure should be limited during the brightest period the day, which is generally between 11 in the morning and three in the afternoon. Sometimes, only spindle cells are present. Clinical examination often shows an exophytic, polypoid mass with a smooth, ulcerated surface. 2-34). Spindle cell tumors will commonly grow back in the same location if they are not removed completely by surgery. (B) Apico-basal orientation. Spindle cell carcinoma. For practical purposes, it is advisable to consider a pleomorphic spindle cell lesion occurring at the mucosal surfaces at the UADT to be an SpCC.353. Very rare RMS with epithelioid and spindle cell morphology, female predominance, marked osseous predilection, ALK expression, EWSR1/FUS-TFCP2 gene fusions, and highly aggressive clinical behavior have recently been recognized with only 23 cases reported in the English language literature. LewisJr., R.D. Based on its clinical appearance, sometimes the tumor may be mistaken for a fibroma or other benign lesion. This discussion on SpCC and its differential diagnosis is finalized by remarking that SpCC sometimes may assume the appearance of an innocuous granulation tissue polyp. Only after several recurrences, the lesion may reveal the more characteristic appearance of an SpCC (Fig. Currently, there is ample evidence that SCC cells can exhibit differentiation toward cells with a mesenchymal phenotype. Spindle cells always express vimentin and often other mesenchymal filaments, such as myogenic markers (smooth muscle actin, muscle specific actin, desmin). At other body sites, the label pseudoangiosarcomatous carcinoma has been used for lesions with this histomorphology.365 It must also be mentioned that conventional SCC sometimes contains myxoid areas with enlarged stromal cells exhibiting swollen vesicular nuclei, sometimes showing mitoses. Spindle cell carcinomas, although fundamentally differentiating into epithelial cells, lose much of these features and gain some features of mesenchymal cells. In the larynx, true sarcomas (with the exception of chondrosarcoma) and benign mesenchymal tumors are very rare. Sixty percent of 53 patients with tumors of the oral cavity died within 1 month to 6 years, 77% of 13 patients with tumors of the sinonasal tract died within 6 months to 2.5 years, and 34% of 65 patients with tumors of the larynx died within 4 months to 2 years. This type of cancer can occur on nearly any of the onnective tissues of the body, including the stomach, muscles, and lungs. When cells from this type of cancer are viewed under a microscope, they appear spindle-shaped. The 31 cases of spindle cell carcinoma were tested for p16 immunohistochemistry and either RNA in situ hybridization or RT-PCR for high-risk HPV.

Microscopically, the SCC component may be well-, moderately- or poorly differentiated, keratinizing or nonkeratinizing, and transition between the two components may be abrupt or gradual. Chernock, in Pathobiology of Human Disease, 2014. One of the main symptoms of the disease is a mass or tumor on the skin, sometimes resembling an ulcer or sore. However, these cells are dispersed among a non-neoplastic background and not densely packed in whorls of fascicles as in SpCC, which identifies them as part of a stromal reaction. (b) Higher-power view of the spindle cell (sarcomatoid) component showing poorly formed fascicles of pleomorphic malignant spindle cells (20 ×). 2-30). SpCC also shows features of epithelial-mesenchymal transition, e.g., up-regulation of transcription repressors (Snail, Slug, SIP and Twist etc.) Therefore, they have to be considered a variant of SCC in which the pleomorphic component originates through dedifferentiation of the SCC component.353–360 Molecular pathology has recently provided convincing proof of an evolution of the sarcomatoid component from the conventional one.360 Metastasis is to the cervical lymph nodes; the deposits may exhibit conventional SCC, SpCC, or both together.355,357,361,362, An SpCC typically occurs in the oral cavity and the larynx355,362; less frequently, it may arise in the sinonasal area and pharynx. Spindle cell carcinomas are characterized by a proliferation of spindle cells with varying degrees of atypia and mitotic activity, often exhibiting transitions with areas displaying the features of conventional spindle cell thymoma (Fig. When cells from this type of cancer are viewed under a microscope, they appear spindle-shaped. Spindle cells with a vague storiform pattern of DLBCL are not familiar to pathologists. Spindle cell carcinoma represents a rare variant of squamous cell carcinoma, characterized by spindled tumor cells that simulate a sarcoma but are epithelial in nature. 2-31). Once the cancer has spread to other areas, symptoms can include fatigue, nausea, pain, and bruising. McDowell's Herbal Spindle Cell Cancer Support Mix can be used in conjunction with other alternative medicines or with orthodox medical treatments such as surgery, radiation and chemotherapy. Sometimes SpCC exhibits acantholysis; in this way, spaces lined by pleomorphic cells are formed that may mimic angiosarcoma (Fig. The most prominent locations for spindle cell sarcoma to develop are in the limbs, but it can form in any part of the body. The epithelioid cells have a resemblance to thymomas or thymic carcinomas with epithelioid to spindle-shaped cells arranged in sheets and nests (Figure 24-89). However, in a series of early-stage (T1–T2) glottic tumors, patients with SpCC treated with irradiation had control rates similar to those of irradiated patients with disease of similar volume with the more typical SCC.371, AUDREY LAZENBY, in Surgical Pathology of the GI Tract, Liver, Biliary Tract, and Pancreas (Second Edition), 2009, Spindle cell carcinoma, also termed carcinosarcoma, pseudosarcoma, polypoid carcinoma, sarcomatoid carcinoma, and spindle cell variant of squamous cell carcinoma, is a rare type of malignant tumor that often grows as an exophytic polypoid lesion (see also Chapter 20).17 These are bulky intraluminal masses that most often develop in the mid esophagus of middle-aged to elderly men (80%).18, 19 The most common presenting symptom is dysphagia, followed by weight loss and pain.18 Typical radiologic features include the presence of a dilated esophagus expanded by a polypoid bulky mass with a smooth or scalloped margin.
