A unique cutaneous presentation of Burkitt lymphoma.

Few reports of cutaneous Burkitt lymphoma exist in the literature. Here, the authors describe the case of a human immunodeficiency virus-positive individual with the rare diagnosis of cutaneous Burkitt lymphoma. Three weeks before the development of his cutaneous lesions, the patient experienced bilateral lower extremity paralysis, and an epidural mass was found. Bone marrow biopsy findings and serum protein electrophoresis seemed consistent with multiple myeloma. The visible appearance of the skin lesions raised concern for cutaneous involvement by myeloma; however, the skin biopsy showed morphological and immunohistochemical features of Burkitt lymphoma. In this case report, the authors discuss the histopathologic findings of the cutaneous lesions in consideration with the bone marrow biopsy findings.
