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. Sarcomas are tumors that arise in the soft, connective tissues that support and surround the organs and other structures of the body. 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. When SCC and spindle cells are both observed, the diagnosis of SpCC is easily made. However, sarcomas in the head and neck area located at mucosal surfaces are extremely rare, and, when they do occur, an intervening fibrous layer usually separates the lesion from the overlying epithelium. The tumor can arise anywhere within the upper aerodigestive tract, with a predilection for the larynx and oral cavity. Combined chemoradiation therapy frequently shows similar findings but with a greater degree of mucosal and submucosal glandular atypia and distortion. There are really no clinical symptoms that would distinguish this particular cancer from other types of breast cancers. Spindle cell sarcoma is a rare malignant (cancerous) tumour which can develop in the bone or soft tissue. Both were T4 tumors and had poor outcomes. It can arise in any part of the body but is most common in the limbs (arms and legs). 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. Spindle cell carcinoma generally exhibits a worse prognosis than conventional squamous cell carcinoma. {"}Spindle cell{"} is a descriptive phrase that denotes the cellular shape of many of the sarcomas encountered in the adult population. 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. The type of tumour depends on the location in the body and the way the cells look when examined under the microscope. Only two cases had detectable HPV RNA, only one of which was strongly p16-positive. If such tumors are less cellular, they may mimic benign reactive lesions. 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. Exact symptoms will depend on where the cancer has spread. Spindle cells with a vague storiform pattern of DLBCL are not familiar to pathologists. 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. J.S. Lester D.R. 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. There is no definite known cause for this type of tumour, but it can sometimes occur as … spindle cell carcinoma A carcinoma—often squamous cell—which can occur on any epithelial surface (e.g., oral, anorectal, bladder, etc). 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 only known cause of … The cells show mild to moderate nuclear pleomorphism, with large, round to oval nuclei with pale to vesicular-appearing chromatin, distinct but small nucleoli, and abundant eosinophilic cytoplasm with indistinct cell borders (syncytial arrangement; Figure 24-89). 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. Spindle cell carcinoma and carcinosarcoma are rare, high-grade primary thymic epithelial neoplasms characterized by a spindle cell, sarcomatoid appearance. The dual-positive case was from the larynx, and the other HPV RNA-positive case was from the oral cavity. Keywords: Spindle-cell carcinoma, Second primary tumor, Synchronous cancer I. 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. The spindle is oriented perpendicular to the tissue axis. Those which are situated right next to an important artery or organ system may be inoperable. However, spindle cell tumors can appear on the skin of a dog or cat as well, and be rather frustrating. The patient may complain of swelling, pain, paresthesia, persistent ulceration, or bleeding. Spindle cell sarcoma is an uncommon cancerous lesion or tumor that forms in an individual's soft tissues or bone. Spindle cell squamous carcinoma (SpCC) is an exceedingly rare variant of squamous cell carcinoma (SCC) with unique clinicopathological characteristics. Spindle cell sarcoma occurs more often in men than it does in women, and it is known to most commonly affect individuals past their fourth decade of life. The cause of the cancer is generally unknown, but it is influenced by … Similar to conventional SCC, SpCC has been etiologically related to cigarette smoking and alcohol consumption. Whether or not the entire mass can be removed will depend on where the tumor is located. Although reported survival rates vary, one recent study based on epidemiologic data from the United States reported 5-year disease-specific survival of 39% for spindle cell carcinoma of the oral cavity. Because these tumors demonstrate prominent exophytic growth with less extension into the esophageal wall, they have been associated with relatively good survival rates. There is a component of SCC in situ at the base of the polypoid mass (arrow) confirming this to be a carcinoma and not a true sarcoma (2 ×). Distinguishing between monophasic SpCC and spindle cell sarcomas such as fibrosarcoma and leiomyosarcoma may be more difficult. Spindle cell tumors will commonly grow back in the same location if they are not removed completely by surgery. 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. Recently, p63 has been reported as a useful marker for SpCC.364, As SpCCs may, in their spindle cell component, exhibit not only vimentin expression but also other mesenchymal filaments, especially myogenic markers, positivity for this marker does not rule out a diagnosis of SpCC.359 Even the absence of keratin positivity cannot be considered evidence against a diagnosis of SpCC, as this may be due to loss of reactivity for antikeratin antibodies due to fixation or embedding procedures or to a phenotypic change of the tumor cells. The diagnosis of this condition may be challenging. 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. Treatment of SpCC is the same as for conventional SCC. The most prominent locations for spindle cell sarcoma to develop are in the limbs, but it can form in any part of the body. Spindle cell sarcoma is a type of cancer which occurs on the connective tissues of the body. Spindle cell cancer is strongly associated with cigarette smoking, as our patient had a significant smoking history as well . Spindle cell sarcoma is a soft-tissue tumour which can start in the bone. Lymphocytes and plasma cells may be present. Spindle cell carcinomas, although fundamentally differentiating into epithelial cells, lose much of these features and gain some features of mesenchymal cells. 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. Any large mass, ulcer, sore, or discolored areas of skin should be checked by a trained medical professional.
