Granular cell myoblastoma of the vulva in a 6-year-old girl.
Granular cell myoblastomas are rare neoplasms thought to arise in neural tissue resembling Schwann cells. About 7% of these tumors are located on the vulva. This is the second reported case in a prepubertal girl with both cases having been found in 6 year olds. None of the vulvar lesions have been malignant. The treatment is wide surgical excision and observation for recurrence. Extragenital sites should be evaluated since multiple tumors are found in a number of patients.
