A case with Penile Mondor's disease

Mondor's disease (MD) is a rare disorder characterized by superficial thrombophlebitis or subcutaneous venous thrombosis. It is commonly seen on the anterior chest wall. Penile Mondor's disease (PMD) is seen less frequently than thoracic MD and presents as an indurated cord-like lesion along the vein tract. A 47-year-old patient presented to our outpatient clinic with a complaint of a painless, indurated, and sudden-onset lesion on the penis shaft that lasted for 15 days. He was using systemic steroids and antidiabetics for pemphigus and diabetes. He had a cord-like lesion along the penis shaft, becoming more prominent by stretching the skin. He was clinically diagnosed with PMD, regressing spontaneously after 1-week of sexual rest. He denied other triggering factors except for strenuous sexual activity. In this case, we think that diabetic angiopathy and the prothrombotic effect of steroids may have contributed to the development of PMD besides vigorous sexual activity. We found it valuable to share because of its rarity.
