Plexiform neurofibromatosis of penis: a rare presentation of type 1 neurofibromatosis.

Although more than 100 cases of genitourinary neurofibromas have been reported, only 16 cases of solitary neurofibroma arising in the penis have been reported in English literature. There can be diffuse or localised pelvic involvement in cases of neurofibromatosis and sometimes these masses can extend into and disfigure the external genitalia. We report an unusual case of plexiform neurofibroma arising from penis and review the literature on penile neurofibromas.
