Angiosarcoma of the head and facial skin: the 69-year-old patient noticed this rapidly growing and recurrently bleeding 3x5 cm large, little symptomatic node around the capillitium for 6 months. After incomplete preliminary surgery within a few weeks formation of the present recurrent node. The inconspicuous erythema around the node is noticeable. After the micrographically controlled surgery, the tumor was only free of tumor after an approximately 10 x 10 cm large excision.
