Summary
Description Histopathology of carcinoma of the thyroid with Ewing family tumor elements, and intrathyroid thymic carcinoma.jpg |
English:
Carcinoma of the thyroid with Ewing family tumor elements (CEFTE) disclosing solid nests of small cells with regular, round nuclei, and nests of papillary thyroid carcinoma (PTC) (a). This case is from a 17-year-old female patient with bilateral involvement of the thyroid by a malignant thyroid teratoma (b); the tumor discloses nests of small cells, rich stroma with chondroid appearance and an epithelial-tubular component. Mixed medullary and papillary thyroid carcinoma (c); the medullary thyroid carcinoma component stained positively for calcitonin mRNA while the PTC (follicular variant) component was negative (d). Intrathyroid thymic carcinoma (ITC) also known by the acronym (CASTLE) showing positivity for CD5 (inset) (e). Spindle epithelial tumor with thymus-like differentiation (SETTLE) is a lobulated tumor composed of spindle cells and epithelioid cell component with glands, mucinous cysts, and/or squamous nests (f and g)
