Mondor's phlebitis of the penis: a study with factor VIII related antigen.

Four patients with so-called non-venereal sclerosing lymphangitis of the penis are reported. It was suggested that the affected vessels were veins by positively stained factor VIII related antigen with the unlabeled peroxidase-antiperoxidase method. If cord-like linear subcutaneous swelling observed in the coronary sulcus or dorsal region of the penile shaft originate from the vein, it seems correct to call this disease as Mondor's phlebitis of the penis.
