Parameatal cyst in a 4-year-old boy

Abstract

A 4-year-old boy presented a translucent cyst on the left lateral side of the urethral meatus. The lesion was excised. Histological examination showed features of a cystic lesion within the dermis surrounded by a thin epithelium of columnar cells with a round apical pole. Immunohistochemical staining was positive for pan-cytokeratins (AE-1/AE-3) and negative for actin. These findings led to a diagnosis of urethral parameatal cyst. In conclusion: this entity is a rare congenital malformation and consists of a parameatal benign cyst occurring in prepubertal males. Treatment consists of complete resection of the cyst. © 2013 Springer-Verlag Berlin Heidelberg.
