title: Granular cell tumor in the perineum. A review and case report.
abstract: Granular cell tumor is a lesion which clinically often resembles a fibroma. The tumor is, however, frequently ill-defined, and it may be mistaken for a malignant growth. The granular cell tumor is only rarely located to the perineum. A total of 55 cases have been reported. The diagnosis can be obtained by frozen section microscopy. Recurrence is prevented by excising the whole lesion. The development of malignancy is extremely rare.
