The terms "thyroid" and "thyroid gland" were used in conjunction with "tall cell variant papillary carcinoma" and/or "squamous cell carcinoma" or "spindle cell squamous cell carcinoma." Apart from the de-differentiation process, the differential diagnosis of SCC inside the thyroid gland included primary SCC, metastatic disease from head and neck cancer, invasion from local structures, and the development of spindle cell squamous carcinoma which is a subtype of anaplastic thyroid carcinoma. Anaplastic thyroid carcinoma, spindle cell pattern, 8.4 cm, with extensive extrathyroid extension involving skeletal muscle and nerves (see comment) Extensive lymphovascular invasion identified Metastatic carcinoma in 2 out of 4 lymph nodes (2/4) BCPAP and 8505C cells were treated with or without 10 µM ⦠A total of 162 articles were generated from the search of which only articles with cases documenting SCSC arising ⦠Pathology - Research and ⦠cinoma using peroxidase-mtiperoxidase technique.

We report a case of 60 year old man who presented with 2 months history of rapidly growing thyroid enlargement with no obstructive features and preliminary diagnosis of spindle cell lesion of thyroid ⦠H&E stain. Very rarely, some of these cancers can progress to spindle cell squamous carcinoma (SCSC) resulting in cancers with elements of both ⦠Evidence demonstrating that anaplastic spindle-cell and giant-cell tumors of the thyroid gland may originate from well-differentiated thyroid carcinomas is rapidly accumlating.5-9,11,13 This is a report of 53 cases of spindle-cell and giant-cell anaplastic tumors of the thyroid gland which were found with ⦠While 83% of the additional tumors appeared in a metachronic form, these two thyroid can Fig 2. Schwannomas may progressively enlarge causing compressive symptoms and mimicking more aggressive spindle cell tumors such as spindle cell papillary, medullary or anaplastic thyroid cancer and thyroid ⦠Prognosis of a rare subtype of thyroid cancer. Liposarcoma is a rare cancer that grows in the cells that store fat in the body. This spindle cell variant due to its pleomorphism and giant cells can mimic the spindle cell variant of papillary carcinoma thyroid, medullary carcinoma or anaplastic carcinoma of thyroid and SETTLE. In summary, the lesion in this case has a spindle cell morphology, is juxtaposed to an area of well-differentiated papillary thyroid carcinoma, and stains positively for cytokeratin AE1/AE3 and P53, while only the adjacent papillary thyroid carcinoma stains positively for TTF-1. Anaplastic carcinoma (also called giant and spindle cell cancer) is the most dangerous form of thyroid cancer. Furthermore, ATC can have many different synonyms such as âundifferentiated,â âsarcoma,â âsarcomatoid,â âsquamous type,â and âspindle cellâ thyroid cancer. We exclude the possibility of these malignant tumours by immunohistochemical markers â ⦠Encapsulated or infiltrative tumor separated by sclerotic stroma. Diagnostic evaluation by experienced endocrine pathologists is recommended due to the rarity of the disease and difficulty in making an accurate diagnosis. Anlotinib induces G2/M arrest and abnormal spindle assembly in thyroid carcinoma cells.

It is rare, and spreads quickly. cers were ⦠Spindle cell in thyroid carcinoma with large intracytoplasmic granules, abundant rough endoplasmic reticulum, Fig. Medullary carcinoma is a cancer of non-thyroid hormone-producing cells that are normally present in the thyroid ⦠Spindle cell carcinoma is rare. There was a tumor in the right lobe of the thyroid measuring 7 by 5.5 by 3.5 cm. The prognosis of giant and spindle cell carcinoma of the thyroid is extremely poor. These tumors grow slowly, and they can spread to other parts of the body. It does appear, however, that a multidisciplinary approach to treatment of this aggressive cancer is more effective than a singleâtreatment modality. Tall cell variant (TCV) of papillary thyroid carcinoma (PTC), an aggressive form of thyroid cancer, is characterised by 50% of cells with height that is three times greater than the width. Follicular tumor is more likely to come back and spread. It is considered to be a biphasic tumor that is composed of a squamous cell carcinoma (in situ or invasive) and spindle cell carcinoma with ⦠These spindle cell lesions includesolitary fibrous tumor, leiomyoma, spindle epithelial tumor with thymus-like differentiation, spindle squamous cell carcinoma, and especially peripheral nerve sheath tumor (Schwannoma or MPNST). Follicular thyroid carcinoma, spindle cell variant is extremely rare. Spindle cell sarcoma of thyroid represents a rare entity that may arise primarily from thyroid gland as a variant of thyroid cancer or as metastatic. The tumor is predominantly composed of spindle cells with a fusiform appearance that are arranged in intersecting fascicles. Eightyâfour cases of spindle and giant cell carcinoma of the thyroid were reviewed. ), containing nucleoli. In 1991, Bronner and LiVolsi described a series of patients with TCV that progressed to spindle cell squamous carcinoma (SCSC), a unique form of anaplastic thyroid carcinoma. Spindle cell carcinoma (SpCC) or sarcomatoid carcinoma is a highly malignant variant of squamous cell carcinoma which comprises 2% to 3% of all laryngeal cancers. In the neck dissection American Journal of Surgery Papillary Carcinoma of Thyroid 663 FIG. Microscopically there was papillary carcinoma of the thyroid with large areas of spindle and giant cell metaplasia. Undifferentiated (anaplastic) thyroid carcinoma (UTC), medullary thyroid carcinoma (MTC), and spindle cell tumor with thymus-like differentiation (SETTLE) are all thyroid epithelial tumors that can mimic sarcomas with a spindle cell pattern. Spindle thyroid cancer. Nishiyama, R.H., Dunn, E.L. and Thompson, N.W. The prognosis of giant and spindle cell carcinoma of the thyroid is extremely poor. Squamous cell carcinoma of the thyroid (SCT) is an unusual neoplasm thought to arise as a primary tumor or as a component of an undifferentiated carcinoma. 16 Soft tissue tumors of the thyroid are uncommon. 97, No. Anaplastic thyroid cancer: wide variations in appearance; subtypes show spindle cell pattern, pleomorphic giant cell pattern, and squamoid pattern; use of special stains or immunohistochemical studies may be required to to exclude other treatable entities with better prognoses. (1972) Anaplastic Spindle-Cell and Giant-Cell Tumors of the Thyroid Gland. This is a swiftly growing, and rapidly fatal neoplasm that generally develops in the elderly. Encapsulated follicular variant of papillary thyroid carcinoma/noninvasive follicular thyroid neoplasm with papillary-like nuclear features with Spindle Cell Metaplasia: Case report and review of literature. Spindle cell follicular thyroid tumors should also be distinguished from benign conditions such as thyroiditis and post-FNAB-related reactive changes, as well as from various neoplasms including solitary fibrous tumor, spindle cell hemangioma, spindle cell variant of medullary thyroid carcinoma, and intrathyroid thymicârelated neoplasms with spindle cell ⦠The variable presentations of anaplastic spindle cell squamous carcinoma associated with tall cell variant of papillary thyroid carcinoma.

Biphasic pattern: spindle cells and epithelial structures (cords, tubules, papillae or glandular formation) Rare monomorphic variant can have spindle cells or glandular only ( Histopathology 1998;33:71 ) No or rare lymphocytes. Myxoid/round cell liposarcoma, or MRCLS, is one of several types of liposarcoma. Given the anti-proliferative effect of anlotinib on thyroid cancer cells, we asked whether anlotinib inhibits cell proliferation by regulating cell cycle progression. Medullary thyroid carcinoma. 4. MRCLS usually grows in the arms and legs. Spindle cell thyroid carcinoma (SCTC) is a rare type of squamous cell carcinoma; it originates in poorly differentiated elongated epithelial cells that features as a sarcoma-like proliferation.
