title: Primitive neuroectodermal tumor of the thumb metacarpal bone: a case report and literature review.
abstract: A 27-year-old otherwise healthy patient was diagnosed with a primitive neuroectodermal tumor of the thumb metacarpal bone of the left hand. Based on a common chromosomal translocation this tumor shows a close relationship to Ewing's sarcoma. Its occurrence in the extremities is uncommon and involvement of the hand is extremely rare. The treatment consisted of neo- and adjuvant chemotherapy and marginal resection of the affected thumb metacarpal bone including periosseous soft tissue and reconstruction of the thumb by an intercalated segmental index pollicization.
