Lymphedema due to chronic penile strangulation: a case report.

A 62-year-old man was admitted with swelling of the penis caused by long term use of a penis enlarging ring. For the previous 20 years, he had noticed small pruritic nodules on his penis. He had no micturitional or ejaculatory impairment. The penis had a diameter of 6 cm, a length of 10 cm, and was covered with thickened skin. The penis and the scrotal skin were covered with scattered, small, hemispheric nodules and papules ranging in size from 2 mm to 1 cm. Pathologic examination of the biopsied specimen from a nodule revealed enlargement of the lymphatic vessels of the dermis and fibrosis. This was compatible with lymphedema due to chronic strangulation by the ring. Scar resection and full thickness skin grafting was performed to prevent malignant changes in the lesions.
