 Diagnosis:  Parameatal Cyst

Plan: This is an unusual lesion.  Although the definitive treatment is surgical excisison, a small lesion may be observed.  Little is known about the behaviour of these uncommonly observed lesions.  We will try to identify a paediatric urologist who has some expertise with these lesions.

Abstract: A parameatal urethral cyst is a very rare congenital anomaly. It was first reported in two males in 1956 by Thompson and Lantin. About 50 cases have been published since then. Most of the cases which have been reported were from Japanese population and on extensive literature search, few cases were found to have been reported from India. We are reporting a case of a parameatal urethral cyst in a 7-year-old boy. Complete excision of the cyst with total removal of the epithelium is required for treatment and for prevention of recurrence.
