Sclerosing lymphangitis of the penis occurs as a skin-colored or dusty red, cord-like thickening of tissue at the corona or within the coronal sulcus. The thickened, elongated lesion is firm and relatively nontender. The cause is unknown : because it occurs primarily in those who are sexually very active, however, it is likely that chronic trauma palys an important etiologic role. We experienced a case of pathologically proven sclerosing lymphangitis in a 31 year-old man. Ultrasonographic finding showed circumferential cord like hypoechoic band with irregular, but well demarcated margin.
