Abstract:
Histoplasmosis due to Histoplasma duboisii is an emerging AIDS-defining opportunistic infection in HIV positive seen predominantly on the African continent between the Tropics of Cancer and Capricorn. Histoplasma duboisii is an invasive fungal organism with tropism for lymph nodes, skin and bones. The infection occurs more in patients with a CD4 count <50/mm3 and is usually dissemnnated Histoplasmosis due to Histoplasma duboisii is an emerging AIDS-defining opportunistic infection in HIV positive seen predominantly on the African continent between the Tropics of Cancer and Capricorn. Histoplasma duboisii is an invasive fungal organism with tropism for lymph nodes, skin and bones. The infection occurs more in patients with a CD4 count <50/mm3 and is usually disseminated. Literature reports of its occurrence in HIV negative patients are scanty. We report a case of histoplasma dubiosii infection of the left femur in a 9 year old HIV negative Nigerian with swelling in the left thigh of 5 months duration. Oral antibiotics and analgesics were prescribed for the patient with satisfactory clinical outcome. To our knowledge, this is the first reported case in an immunocompetent child in Nigeria.

Insights
Histoplasmosis due to Histoplasma duboisii is an opportunistic infection common in HIV patients. This report details a rare case in an immunocompetent Nigerian child, highlighting its potential occurrence outside typical risk groups.
Area of Science:
- Mycology
- Infectious Diseases
- Public Health
Background:
- Histoplasmosis caused by Histoplasma duboisii is an emerging AIDS-defining opportunistic infection.
- It primarily affects HIV-positive individuals in tropical Africa, targeting lymph nodes, skin, and bones, especially in those with CD4 counts below 50/mm³.
- Cases in HIV-negative individuals are rare.

Spongy Bone
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...
Compact Bone
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
