A 16-year-old Japanese boy presented with a tumor on the left side of his back. His mother had noticed it when he was a baby. Since then, it had gradually increased to 31 x 18 x 3 cm in size. It was pale blue, elastic soft, and lobular (Fig. 1). On its top, there was a red nodule. A sensory abnormality and hypohidrosis were detected at the lesion site (Fig. 2), but laboratory findings were within normal limits. In a CT examination of the lesion, the skin overlaying the lesion was found to be thicker than normal skin, and an isodensity tumor was present at subcutaneous level. It was situated close to the muscle (Fig. 3).
