Penile nodule in a young adult.

A 20 year old male presented with a nodule, 1.25 cm x 1 cm, on the ventral aspect of the foreskin of his penis. The nodule was excised by circumcision. On histology it was found to be a multiloculated cyst located in the dermis of the prepuce. It contained eosinophilic material and was lined by pseudostratified columnar epithelium. There was no evidence of inflammation or malignancy in any of the sections of this median raphe cyst. The aetiology of such cysts is discussed in addition to a review of the literature.
