초록

Spindle cell liposarcoma is a variant of well differentiated liposarcoma. It is a low grade sarcoma capable of recurrence, dedifferentiation, and metastasis. We experienced a case of spindle cell liposarcoma in left posterior neck of a 70 year-old man. On physical examination, the tumor was movable and measured 10cm in diameter. Microscopically, the tumor showed hypocellular myxoid or hyaline areas alternating with areas showing greater cellularity.The tumor mainly consisted of spindle cells. The intercellular matrix showed myxoid change. The tumor also showed an adipocytic component.The atypical adipocytic cells were positive for s100 protein.
