Isolated Bone Marrow Involvement of Lepromatous Leprosy in an HIV-infected Patient with No Apparent Skin Lesions: A Case Report

Authors: Joshua Shadrach Daniel, Kwee Choy Koh, Thin Thin Win

ABSTRACT

Leprosy caused by Mycobacterium leprae, primarily manifests with cutaneous and neurological symptoms. Bone marrow (BM) involvement without skin lesions is exceedingly rare, particularly in immunocompromised patients. Here is a case of a 40-year-old HIV-infected man with a nadir CD4 count of 29 cells/mm³ who presented with recurrent anaemia, massive hepatosplenomegaly, and no apparent skin lesions. BM analysis revealed epithelioid granulomas with foamy histiocytes containing acid-fast bacilli, confirmed by Wade-Fite staining. This case highlights the rare presentation of lepromatous leprosy, emphasising the diagnostic challenges posed by the absence of typical cutaneous features.
