Cutaneous angiosarcoma is a rare aggressive vascular neoplasm with a poor prognosis, seen usually in the elderly population in a background of chronic lymphedema. We present a case of cutaneous angiosarcoma of the leg without any chronic lymphedema with clinicoradiological and histological correlation.

Angiosarcoma (AS) is a rare, aggressive malignancy originating from vascular or lymphatic endothelial cells. Despite its severity, little is known about its epidemiology, and no geographical regions have previously been identified as having an exceptionally high incidence. We retrospectively analyzed medical records spanning 37 years (1987-2023) in Okinawa, Japan, identifying 135 cases of AS that were used to calculate its incidence.

Composite hemangioendothelioma comprises permutations of different histological patterns few of which have been found to have specific genetic alteration and immunohistochemical expression. It comprises retiform or epithelioid hemangioendothelioma-like areas, with a variable proportion of hemangioma or low-grade angiosarcoma-like areas. It was found to express neuroendocrine markers and was seen to have a worse prognosis in recurrence or distant metastasis.

While most forms of alopecia neoplastica are attributable to cutaneous metastases from visceral primary malignancies, rarely a diffuse primary skin cancer may present as alopecia. Herein, we present a case of angiosarcoma which clinically mimicked an inflammatory alopecia and was diagnosed by examination of alopecia-protocol horizontal histologic sections. A 72-year-old female presented to her dermatologist with a chief complaint of hair loss and pruritus.
