Abstract

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.
