[Linear cystic lesion of the median raphe in an 11-year-old child].

Background: Median raphe cysts are rare benign lesions of the male genitalia. They may be present along the entire raphe, from the urethral meatus to the anus, in the median position. We report herein a case of median raphe cyst with an atypical clinical and histological presentation.

Patients And Methods: An 11-year-old boy consulted in dermatology for an asymptomatic perineal lesion. The clinical examination revealed a linear cystic lesion with clear content extending from the base of the scrotum to the anus. The histological diagnosis was a superficial dermal glandular cyst suggestive of a possibly apocrine origin in this topography, or possibly due to malformation.

Discussion: Different clinical and histological features of median raphe cysts have been reported in the literature. Treatment is mainly surgical.
