Abstract
In this report, we describe a case of a healthy 67-year-old female with rapidly growing red nodules on the scalp that demonstrated histological features of benign epithelioid hemangioma on multiple instances yet behaved clinically as a malignant angiosarcoma. Despite multiple rounds of resection, radiation, and chemotherapy, the patient ultimately succumbed from her widely metastatic disease. Diagnosis of vascular neoplasms, including the spectrum of low-grade epithelioid hemangioma, intermediate-grade epithelioid hemangioendothelioma, and high-grade angiosarcoma remains challenging due to overlapping clinical and histopathological features. This report is presented to highlight the need for clinicians to interpret histopathology, whether benign or malignant, in the context of clinical observation as the clinical course may not always match the biopsy.
