Bacillary angiomatosis: A rare finding in the setting of antiretroviral drugs

An HIV-positive 39-year-old man presented with generalised nodular lesions. He was apyrexial and normotensive, with a normal respiratory rate. The rest of the examination was normal. He had been on antiretroviral therapy for >4 years; most importantly, he was on a secondline regimen (lopinavir/ritonavir (Aluvia) based). The appearance of the lesions, together with the history, led to the following possible diagnoses: bacillary angiomatosis, cutaneous cryptococcosis, nodular Kaposi sarcoma or cutaneous histoplasmosis.
