# Cutaneous Angiosarcoma Mimicking Masson’s Tumor in an Elderly Male: A Diagnostic Challenge and Treatment Failure

## TL;DR

An elderly man's facial lesion was initially mistaken for a benign tumor but was later diagnosed as aggressive cutaneous angiosarcoma.

## Contribution

Highlights the diagnostic challenge of distinguishing cutaneous angiosarcoma from benign vascular lesions like Masson’s tumor.

## Key findings

- Cutaneous angiosarcoma can mimic benign vascular tumors, leading to delayed diagnosis.
- The case emphasizes the need for careful evaluation of asymptomatic skin lesions in elderly patients.
- Failure to recognize angiosarcoma early can result in metastasis due to its aggressive nature.

## Abstract

Cutaneous angiosarcoma is a rare tumor that may resemble other vascular lesions, such as Masson’s tumor. It may present as asymptomatic nodules, patches, or plaques, which are most commonly seen in the central face, scalp, or neck. It is an aggressive cancer that originates from endothelial cells that line blood or lymphatic vessels, and since it may present similarly to other benign tumors, recognizing it is essential to prevent the risk of further growth and potential metastasis. This case report presents an elderly male with an asymptomatic facial lesion, initially diagnosed as Masson’s tumor, but later recognized as cutaneous angiosarcoma. We present a previously healthy 82-year-old African male with a two-month history of an asymptomatic facial lesion. Examination revealed multifocal erythematous to violaceous nodular growths involving both cheeks, the nasal bridge, and the periocular regions. This case report emphasizes the importance of considering cutaneous angiosarcoma in elderly patients presenting with asymptomatic skin lesions.
