Cutaneous angiosarcoma - Mimicking giant condyloma acuminata with molluscum-like satellite lesions.

Abstract

Angiosarcoma (AS) is a rare malignant tumor of vascular or lymphatic epithelium, typically presenting as a bruise-like patch over the face or scalp in the seventh-ninth decades. Here, we report a case of cutaneous AS (cAS) in a 51-year-old male patient who presented with a cauliflower-like growth in the groin with skin-colored shiny flat-topped satellite papules in the surrounding areas, some of which were umbilicated. Based on examination, the patient was considered retro positive and the following differentials were considered: Buschke-Lowenstein tumor with giant molluscum, Kaposi sarcoma, and squamous cell carcinoma. Histopathological examination suggested the diagnosis as AS, which was confirmed by immunohistochemistry that was positive for CD31 and CD34. The report highlights the unusual site and clinical presentation of cAS.
