Angiosarcomas are rare, highly malignant tumours of vascular origin. They present as fast growing, haematoma-like and diffuse lesions. In this case report, a 71-year-old woman presented with what was assessed as an abscess arising from a traumatic haematoma of the forehead. The lesion was primarily treated conservatively. The condition progressed despite of treatment to a point where the tumour covered a third of her face. After four months, skin biopsies were taken and the diagnosis angiosarcoma was made. This case report should lead to an increased focus on angiosarcomas and the importance of sufficient biopsies.
