Fine-needle aspiration cytology of intra-abdominal wall extraskeletal myxoid chondrosarcoma: a case report and review of the literature.

Abstract

Extraskeletal myxoid chondrosarcoma is a rare soft tissue tumor. Most of the reported cases that were diagnosed by fine-needle aspiration were taken from the extremities, where the tumor is often found. Problems can occur when the site is unusual and cellular differentiation is not distinct. We present a case in which the tumor was located in the intra-abdominal wall, an unusual location. Cytologic features and immunocytochemistry are helpful in distinguishing this tumor from others that share similar myxoid background.
