Fibrous hamartoma of infancy masquerading as a rhabdomyosarcoma of the spermatic cord.

Fibrous hamartoma of infancy is an uncommon nonmalignant fibroproliferative tumor found predominantly in the upper torso within the first 2 years of life. We report a case of fibrous hamartoma of infancy, which presented as a rapidly growing scrotal mass clinically indistinguishable from a rhabdomyosarcoma of the spermatic cord. The clinical characteristics of this neoplasm as well as management are discussed.
