Multifocal angiosarcoma of the scalp: a case report and review of the literature.
Neoplasms, Multiple Primary
Multifocal angiosarcoma of the scalp is uncommon. Its risk factors include a history of radiotherapy and possibly sun exposure. Angiosarcoma is an aggressive tumor with a high propensity for both local recurrence and distant metastasis. Overall, the prognosis is poor. The size of the lesion is an important prognostic factor. Treatment modalities include surgery with wide margins (with or without adjuvant therapy) and multidrug chemotherapy, followed by radiotherapy. The local failure rate is high.
