Giant cell tumor of soft tissue in groin region, clinically diagnosed as inguinal lymphadenopathy

Giant cell tumor of soft tissue is a rare primary soft tissue neoplasm with clinical and histological similarities to giant cell tumor of bone. Most cases arise from superficial soft tissue of extremities and present as painless and well circumscribed masses. Adequate surgical treatment by complete excision is associated with a benign clinical course in most cases. We report a case of primary giant cell tumor of soft tissue in groin region of a young man which was thought to be an inguinal lymphadenopathy in clinical examination.
