title: [Granular cell tumor of the male breast].
abstract: The granular cell tumor of the breast (TCGS) is a rare benign tumor, which grows from Schwann cells. It can be confused with a cancerous tumor clinically and radiologically. Only the histological appearance can make the diagnosis. We report a case of TCGS in a man, discovered as a result of self-examination of a breast lump. The authors emphasize the problem of differential diagnosis with breast cancer: clinically, a hard lump with an occasional skin retraction or a fixity to the deep plane; radiologically a stellar opaque appearance with irregular contours, sonographically unspecific, and even macroscopically during surgery, this lesion having morphological characteristics which need histologic examination and even immunohistochemistry in order to exclude a malignant tumor. They are cured by wide local excision and have generally a good prognosis.
