Abstract

We report a case of extraskeletal osteosarcoma in view of rarity, and a brief review of the literature related to this type of tumor is presented. The patient was a 31-year-old Korean woman, who had noticed a bean-sized hard mass in the right thigh progressively enlarged to become egg-size during about 7 months, followed by pain and tenderness. There was neither recognizable previous lesion nor causable agent about the mass on history taking. Physical examination revealed another palpable mass on the inguinal area. The right thigh and inguinal masses were simply excised and histologically confirmed to be an extraskeletal osteosarcoma and metastatic one, respectively.
