Case Report: Hidden acral lentiginous melanoma with cutaneous metastases masquerading as Kaposis sarcoma in an HIV-positive Indian man

摘要

A 33-year-old HIV-positive Indian man presented with multiple bluish and erythematous papulo-nodules on his right leg and foot. A diagnosis of Kaposi's sarcoma was suspected clinically. Biopsy of the cutaneous lesions showed features of melanoma. On careful re-examination, an irregular brown-black macule, of which the patient was unaware, was noted on the ipsilateral sole. Histological examination of the sole lesion also showed features of melanoma. Systemic evaluation revealed extensive nodal and visceral metastases.
