RESUMO
@#Background: A penile median raphe cyst is an uncommon congenital lesion that is formed due to failure of the median raphe to close completely during embryo development. The majority of the cysts are asymptomatic and often go unnoticed. Here, we report acute urinary retention as a very rare complication of a penile median raphe cyst. Case presentation: A 21-year-old single man presented with a sudden onset of acute urinary retention of one days’ duration. Urethral catheterization was done at the Emergency Department and this drained 800 ml of urine. On further questioning, he claimed that he had had a painless nodule at the glans penis since childhood. The swelling increased in size in the past week causing discomfort. He denied any history of genitalia trauma or recent sexual intercourse. On examination, there was a bluish lesion over the ventral aspect of the glans penis measuring about 3 x 2 cm. The lesion was later excised and histopathology revealed a median raphe cyst of the penis. Conclusion: A penile median raphe cyst is a rare lesion. Acute urinary retention caused by this lesion is very rare.
RESUMO
Median raphe cyst (MRC) of the perineum is rare congenital midline cyst of the male genitalia. MRC is thought to be caused by congenital alterations in the embryologic development of the male genitalia during fetal life. MRC can be found on the midline position between the urethral meatus and the anus. The lesion can be cystic, but sometimes it looks like an elongated configuration called a raphe canal. Diagnosis in childhood is particularly rare because they are usually asymptomatic, but some cases have reportedly been identified after infection. Although conservative treatment can be possible in small asymptomatic lesions, the treatment of choice is simple excision followed by primary closure in symptomatic cases. We describe here the case of 2-year-old boy presented at our institution with a 10-month history of anomaly of the perineal median raphe, which was treated by surgical excision.

Median raphe cyst is an uncommon condition occuring on the ventral median raphe from the glans penis to the anus and represents a defect in the embryologic development of the male genitalia. The cyst wall may derive from endoderm, ectoderm, or mucous glands which are a normal constitute of the male urethra. It is classified as either a dermoid cyst lined by stratified squamous epithelium of ectodermal origin or a mucous cyst lined by cuboidal or columnar epithelium of endodermal origin. Surgical excision is the treatment of choice. We report a case of an 11-year old boy with three median raphe cysts of the scrotum. The epithelial lining of the cysts was mainly composed of pseudostratified columnar cells with decapitation secretion and focally showed stratified squamous cells and a transitional zone of two types of cells. Immunohistochemically, pseudostratified columnar cells showed CK 7 and CK 13 positivity, but were negative for CK 20. Besides, stratified squamous cells were negative for CK 7, CK 13 and CK 20. We report a rare case of median raphe cyst that is a combined type of dermoid cyst and mucous cyst.

Median raphe cysts are rare mid-line developmental cysts, which can arise at any point between the external urethral meatus and the anus. They most commonly affect the ventral aspect of the penis, usually near the glans. They tend to be solitary, unilocular cysts, and the inner lining is usually composed of pseudostratified columnar epithelium. We present a case of a 3-year-old boy with a median raphe cyst affecting the glans penis. The cyst, located near the urethral meatus, was slightly pruritic and 0.3cmx0.3cmx0.1cm in size. A shave biopsy, followed by CO2 laser ablation was performed, and histopathological examination revealed a unilocular cyst lined with pseudostratified columnar epithelium, which showed decapitation secretion in part. For 2 years fallawing the shave biopsy, no clinical evidence of recurrence has been observed.

Median raphe cyst of the penis is an uncommon entity that usually presents as a cystic lesion on the ventral aspect of the penis, and which has a broad spectrum of histopathological appearances. It occurs most commonly near the glans penis, but may occur anywhere from the urethral meatus to the anus. It is solitary and measures only a few millimeters in diameter. Surgical excision is the treatment of choice. Recently we observed an 18-year-old male patient who had had a median raphe cyst since 5 years ago near the urethral orifice of the glans penis.

Median raphe cyst is a relatively uncommon lesion occurring in the midline male perineum, especially ventral aspect of penis. It is an embryologic developmental anomaliy of the male genitalia. Histologically, the lining cells are usually pseudostratified columnar epithelium, but can be stratified squamous epithelium and sometimes mucous glands and ciliated cells can be observed within the cyst wall. Herein, we report a case of median raphe cyst in the midline of the scrotum of a 2-year-old boy.

Median raphe cyst is known as congenital lesion of the perineum and genitalia, but its etiology is unclear. Most investigators believe that the median raphe cyst represent defects in the embryologic developenient bf the male genitalia. Simple surgical excision is effective in most cases. We report our experience with two cases of median raphe cyst without specific symptoms. Even though median raphe cyst is asymptomatic, surgical therapy is worth applicable because it relieve a patient from cosmetic and psychotic problem.
