Penile superficial dorsal vein thrombophlebitis following prolonged sexual activity.

Penile Mondor disease (MD) is a palpable, painful, subcutaneous induration resulting from thrombosis of the superficial dorsal penile vein. In this report, we present a 53-year-old case of Mondor disease following prolonged, vigorous sexual activity. He had engaged in sexual activity the previous night after taking sildenafil. Physical examination revealed penile swelling and tenderness over the protruding dorsal penile vein with no evidence of penile fracture. An in-color Doppler ultrasound was promptly performed, revealing hyperechoic thrombosis in the dilated superficial dorsal penile vein accompanied by soft tissue swelling and the absence of a detectable flow signal within the thrombotic lesion. The patient was diagnosed with penile Mondor disease. The patient received conservative treatment. This case highlights the association between prolonged vigorous sexual activity, oral sildenafil uses and the development of penile Mondor disease.
