Median raphe cyst with ciliated cells of the penis.

Sir, Median raphe cysts of the penis are uncommon benign lesions that affect young men. The cysts are lined with pseudostratified columnar or stratified squamous cell epithelium, mimicking the epithelial lining of the male urethra. Immunohistochemical study also indicates a histogenetic relationship with the urothelium. To our knowledge, there have been only 2 reports of ciliated epithelium in this kind of cyst published previously (1, 2). We describe here a rare case of median raphe cyst of the penis with ciliated cells, and discuss the histopathological and immunohistochemical features.
