title: A Recurrent Angiosarcoma Isolated to the Eyelid without the Recurrence on the Primary Lesion of the Forehead.
abstract: Angiosarcoma is a highly malignant vascular tumor of endothelial origin. Initially, a cutaneous manifestation presents as a singular or multifocal bruise-like patches on the skin, most frequently on the face, the scalp or the neck regions. On progression, the lesions become violaceous, and ill-defined spongy nodular tumors appear. Our patient was a 71-year-old man with a previous history of angiosarcoma on the right forehead and was treated with an excision and local radiation 3 years ago. Several months after the treatment, a dark brownish to violaceous patch with edema arose from the right upper eyelid and spread out to the lower eyelid. Clinically, an ecchymosis caused by trauma or other hemangioma was suspected more than a recurrent angiosarcoma. Histopathologic examinations including immunohistochemical studies were consistent with cutaneous angiosarcoma. Herein, we report a rare case of a recurrent isolated angiosarcoma without the recurrence of a primary lesion.
