Why the study?
Angiosarcoma is a rare malignant tumor that typically presents over the face or scalp, making atypical sites and presentations challenging to recognize.
Cutaneous angiosarcoma can present atypically in the groin, mimicking giant condyloma acuminata or molluscum contagiosum.
Atypical groin lesions may warrant biopsy to exclude angiosarcoma; this Level 5 case leaves open questions on prevalence and management.
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.
