Case Report: Cutaneous granular cell tumors [version 1; peer review: 2 approved with reservations]

Granular cell tumors are uncommon tumors in the deep soft tissue of the extremities, especially those with intramuscular origin, with a good prognosis after surgical resection. We present a case study of a 30 year old man with a skin lesion on his shoulder, which was grown in size over the course of 2 months. Complete tumor excision was done and histopathological findings revealed a marked hyperplasia epidermis with pseudoepitheliomatous pattern. The pathologic report was compatible with a granular cell tumor.
