He first noticed several purplish raised areas that transformed into nodules that slowly and progressively increased in size. Biopsy revealed a regular pattern of small blood vessel proliferation, fibroblasts, extravasated erythrocytes, and hemosiderin deposition within the dermis. No endothelial cell atypical mitoses or vascular slits were identified. Polymerase chain reaction (PCR) analysis for human herpesvirus 8 (HHV 8) was negative. A diagnosis of acroangiodermatitis or pseudo-Kaposi sarcoma was made.
