PALMAR WELL DIFFERENTIATED SPINDLE CELL LIPOSARCOMA: PRESENTATION OF A RARE TUMOR AT A RARE SITE

Abstract

The most common soft tissue sarcomas of hand are epitheloid sarcomas, synovial sarcomas and malignant fibrous histiocytomas which are high grade, aggressive tumors. Liposarcomas of the hand are extremely rare and to the best of our knowledge less than 20 cases have been reported so far in the literature. Well differentiated spindle cell liposarcoma is an extremely rare subtype of well differentiated liposarcoma/atypical lipomatous tumor which is different from the other subtypes clinicopathologically, genetically and prognostically. Palmar localization of this rare variant of liposarcoma at this site makes ours only the second case reported in the world literature so far. This recently described entity is low grade lesion and the hand surgeons need to adopt a less aggressive approach in the treatment of this subtype.
