[A case of Mondor's disease of the penis]

A case of Mondor's disease of the penis in a 40-year-old man is reported. The patient complained of a small subcutaneous induration (0.5 x 1.0 cm) with slight tenderness in the dorsal region of the penile shaft. On examination, the linear cord was palpated running both distally and proximally from the induration. This lesion was removed under local anesthesia, and the induration and the cord were found to be part of the superficial dorsal vein of the penis. The venous wall was thick and the thrombus was packed in it. Histological findings showed the proliferation of connective tissue of the vessel wall and partially granulating thrombus in the canal. From these findings, we confirmed the diagnosis of Mondor's disease of the penis. The etiology of this disease, especially in comparison with non-venereal sclerosing lymphangitis of the penis (N.S.L.P.) is discussed.
