title: Merkel cell carcinoma in a black human immunodeficiency virus-infected patient.
abstract: Merkel cell carcinoma (MCC) is a rare malignant tumour that develops in sun-exposed areas in immunocompromised patients (chronic lymphocytic leukaemia, transplant recipients) older than 50 years. We report MCC in a young black woman with human immunodeficiency virus (HIV) infection. A 2-cm binodular violaceous lesion developed on her left ear lobe. Extensive work-up, including computed tomographic scans of the neck, chest, abdomen and pelvis, octreotide scan and sentinel node biopsy, did not demonstrate any metastasis. A wide excision was performed and the patient remained free of disease after 9 months. This case is the fourth observation of MCC in an HIV-infected patient.
