Angiomyolipomatous hamartoma of the upper lip: a rare case in an 8-month-old child and differential diagnosis.

Hamartoma is a proliferation of normal tissues that are considered endogenous to the site of occurrence. In the head and neck region, hamartomas composed of other tissues different from blood and lymphatic vessels (hemangiomas and lymphangiomas) are very uncommon. We report an unusual case of upper lip angiomyolipomatous hamartoma in an 8-month-old patient. The patient underwent surgical treatment and the 1-year follow-up revealed no signs of recurrence. Angiomyolipomatous hamartoma is a very rare condition in the paediatric population group, especially in the head and neck region. It should be considered in the differential diagnosis of congenital lesions in childhood.
