[Alveolar rhabdomyosarcoma: apropos of a rare location].
Rhabdomyosarcoma is a soft tissue tumor of striated muscle origin. It is observed mainly in children and adolescents. Rhabdomyosarcoma predominantly occurs in three regions: head and neck, genito-urinary tract and retroperitoneum, and upper and lower extremities. We report a case of primary alveolar rhabdomyosarcoma of the mesentery occurring in a 68-year-old man. Rhabdomyosarcomas can be diagnosed on microscopic findings and immunohistochemical features. Cytogenetic findings can be helpful in the diagnosis.
