A case of intravascular fasciitis of the upper lip

We describe a case of intravascular fasciitis. A 24-year-old Japanese man visited this hospital in November 1994 because of swelling of the upper lip. Ultrasound examination showed a hypoechoic mass, measuring 10 mm in diameter, with slightly illdefined margins in the upper lip. The mass was ellipsoid and flat, and its inner echo level was heterogerous. Under local anesthesia, the patient underwent resection of the mass. On the basis of these clinical and histopathological findings, we made a diagnosis of intravascular fasciitis of the upper lip. The patient made steady progress after the operation.
