Median Raphe (Parameatal) Cysts of the Penis

Abstract

Median raphe cysts are derived from the external paraurethral ducts and contain features that to our knowledge have not been previously reported.

Mucoid Cyst of the Penis: A Case Report

“…Mucoid cyst also needs to be differentiated from median raphe cyst of the penis, which generally occurs along the median raphe on the ventral surface of the penis. Median raphe cysts which are usually asymptomatic are lined by urothelium or squamous epithelium [7,8]. Mucoid cysts usually, they are asymptomatic but can be complicated by infection, trauma or can make coitus difficult, as with the patient in this report [9,10].…”

“…In general, they are asymptomatic, unless when they are complicated by infection or difficult coitus. 4,8 Although the pathogenesis of the disease has not been well understood by the medical fraternity yet various developmental theories put forth are 'tissue trapping' either due to a defective fusion of the urethral folds or an anomalous outgrowth of the epithelium, which becomes sequestrated and independent after the primary closure of the median raphe. The anomalous developmental rest of the periurethral glands of Littre and blockage of the paraurethral ducts.…”

“…9 In most of the patients, the cysts, which are asymptomatic or unrecognised during childhood, may progress slowly and become symptomatic during adolescence or adulthood. 4 Their proximal location in most of the cases make them asymptomatic. Only one case of a spontaneous onset after an intense sexual intercourse has been documented.…”

“…3 Furthermore, the Differential diagnoses include epidermal cysts, lipomas, esteatocystomas, dermoid cysts, pilonidal cysts, tyson glands cysts and urethral diverticuluns. 4 The cysts are usually small, soft, freely movable, asymptomatic masses unless they are complicated by infection and difficulty coitus. 5 The present case is a giant median raphe cyst of prepuceal skin in an elderly male.…”

Mucoid cyst of the penis: Case report and literature review

“…2 Several terms, including mucus cyst of the penis, genitoperineal cyst of the medium raphe, parameatal cyst, hydrocystoma and apocrine cystadenoma of the penile shaft, should be considered synonymous. 3 They are midline-developmental cysts that can be found…”
