Biker's Nodule : A Case Report and Review of the Literature.

We describe a 17-year-old cyclist who presented with a biker's nodule which is a painful perineal mass resulting from chronic perineal compression and friction during extensive cycling. The treatment of choice is surgical excision. A review of the literature was made concerning this condition. Health care workers who are involved with sportsmen, especially in countries like Belgium where professional and recreational cycling is increasingly popular, should be aware of the diagnostic and therapeutic features of this condition.
