Fine Needle Aspiration Cytology of Low Grade Fibromyxoid Sarcoma

Abstract
Low grade fibromyxoid sarcoma, first described in 1987, is a rare sarcoma characterized by a bland and deceptively benign histologic appearance but with aggressive behavior. A 51-year-old female presented with a history of a recurrent and slowly growing mass in the left foot. Fine needle aspiration biopsy showed an abundant myxoid background with occasional thick bands of collagen. Tumor cells present in the myxoid background were spindle shaped, with focally mild or a light degree of nuclear enlargement, hyperchromasia and pleomorphism Low grade fibromyxoid sarcoma has particular cytologic features. Besides a careful cytologic evaluation of all the components, clinical and radiographic correlation is necessary to make the correct diagnosis.
