Abstract
Alveolar Rhabdomyosarcoma: A case report 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.

Abstract
Rhabdomyosarcoma is a tumor of soft tissues with varying degrees of differentiation in the striated muscular sense. It affects with predilection the child and adolescent and develops preferentially in three anatomical regions: Head and neck, genitourinary tract and retro-peritoneum, and members. Our observation reports a case of primitive alveolar rhabdomyosarcoma observed in a 68-year-old man of mesenteric siege. The diagnosis of this tumor is based on histological and immunohistochemical criteria, possibly supplemented by molecular cytogenetic analysis.
