Parametal cysts of the glans penis: a report of 9 cases.

Nine cases of cysts on the male urethral meatus are reported. These cysts are easily traumatized, occur early in life, enlarge slowly and apparently are not associated with infection, circumcision or trauma. These round, smooth, symmetrical and usually unilateral cysts do not interfere with urinary or sexual function except for an occasional irregularity of the urinary stream. Simple aspiration of the cyst results in recurrences. Marsupialization or unroofing of the cyst, especially if it is large, results in a gaping sinus, which is cosmetically unsatisfactory and should be avoided. Complete excision of the cyst is cosmetically excellent and there have been no recurrences in my cases. The cause of these cysts is postulated as a blockage of the paraurethral ducts.
