Large Solitary Plexiform Neurofibroma of the Penis Without Erectile Dysfunction: a Case Report from Kerala

Solitary plexiform neurofibroma of the penis is an extremely rare peripheral nerve lesion with only about 20 cases reported all around the world. Here, we are reporting a case of solitary penile plexiform neurofibroma with sexual dysfunction due to difficulty in penetration. This 47-year-old gentleman presented with a swelling on the dorsal side of the penis. He was aware of the swelling for the last 15 years. The swelling was slow growing and there was no associated loss of sensation or sexual dysfunction. For the last 2 months, he noticed that the tumour is rapidly increasing in size. He was also having difficulty in penetration during sexual intercourse which forced him to seek medical attention. He underwent excision of the swelling from our department. After 18 months of follow-up following excision, there has been no evidence of recurrence of the tumour.

Penile plexiform neurofibromas are a rare type of lesions and are usually associated with neurofibromatosis. Solitary penile plexiform neurofibromas are extremely rare. Excision, when done properly, gives good results, without erectile dysfunction.
