title: Angiomatoid malignant fibrous histiocytoma. Cytology of fine-needle aspiration and its differential diagnosis.
abstract: A case of angiomatoid malignant fibrous histiocytoma was studied by fine-needle aspiration biopsy and routine histologic methods. Smears from aspirated material consisted of numerous large loose cellular aggregates with occasional single cells. Histiocytelike cells and lymphocytes were the prominent cell types with lesser numbers of spindle-shaped, fibroblastlike cells. Moderate cytologic atypia was noted. A cystic mass with the above cytologic findings occurring in the superficial soft tissue of the extremity of a young patient should suggest the diagnosis of an angiomatoid malignant fibrous histiocytoma.
