Tumor mioepitelial mixto (paracordoma) / Myoepithelial mixed tumor (parachordoma)

Estudio de caso: Paciente de sexo masculino, de 38 años de edad,con tumor ación indolor a en muslo izquierdo de 3 años de evolución. Esta neoplasia corresponde típicamente a nódulos compuestos por células epiteloides poligonales, claras, que recuerdan a las de la notocorda y una segunda población de células e osinofílicas organizadas en cordones y nidos separados por estroma mixoide, con fenómenos de vacuolización citoplasmática similar a las del cordoma (células tipo fisalíferas).

Case Study: Male patient, 38 years old, with painless swelling in left thigh 3 years evolution. This neoplasm typicall y corresponds tonodules composed of polygonal epithelioid cells, clear, reminiscent of the notochord and a second population of eosinophilic cells arranged incords and nests separated by myxoid stroma with phenomena similar to cytoplasmic vacuolization the chordoma (physaliphorous type cells).

An unusual localization of mucormycosis diagnosed by fine needle aspiration cytology: a case report.

Mucormycosis is an uncommon fungal infection, occurring mainly in patients with acidosis, chronic illnesses and malignancies. The most frequent site of involvement in patients of hematological malignancies is the respiratory tract. Isolated subcutaneous localization of mucormycosis in such patients is extremely rare. We report a case of a young patient of non-Hodgkin's lymphoma on chemotherapy who presented with a subcutaneous swelling on the anterior aspect of right thigh. Fine needle aspiration cytology (FNAC) smears from the swelling revealed numerous characteristic broad, irregularly contoured and pleomorphic hyphae of mucormycosis. This fungus seldom grows in culture and confirmation of the diagnosis depends on cytological or histological examination of infected tissues. Our case report documents a rare site of isolated mucormycosis infection and emphasizes the role of FNAC as a simple, rapid, accurate, and useful method of diagnosing fungal infections.
