OBJECTIVE: To describe two additional cases of parameatal urethral cyst. The literature is reviewed and the etiology and treatment of this disease are discussed. METHODS: Two patients aged 20 and 24 years with parameatal urethral cyst are described. The patients were seen at the Gea González Hospital (México) during the period 1987-1988. The first case was asymptomatic and the cyst had been present since birth and in the other case, the cyst appeared at age 24 and caused irregular stream. Laboratory tests, surgical excision and pathological analysis of the cyst were performed. RESULTS: The laboratory tests were normal, no problems were encountered during surgical excision, the symptoms disappeared and there were no postoperative complications or recurrence. Pathological analysis demonstrated columnar epithelium in both cases. CONCLUSIONS: Parameatal urethral cyst is a rare benign condition that is asymptomatic in most of the cases. It may be present since birth or appear later and is prevalent in young males. Its etiology remains unclear and treatment is by complete surgical excision to avoid complications and recurrence.
