Sclerosing lymphangitis is a rare penile lesion characterized by a cord-like, firm swelling at the penile coronal sulcus. It affects males between the ages of 30 and 40 and usually resolves spontaneously. Due to the rarity of this condition, we decided to report this case. Herein, we present a case of a 35-year-old male that was evaluated for a painless, cord-like, penile lesion that enlarges during erection, characteristic of sclerosing lymphangitis.
