Disseminated histoplasmosis mimicking miliary tuberculosis: a case report.
A 35-year-old Chinese man who was known to have insulin-dependent diabetes mellitus was admitted for fever and weight loss. During his hospital stay, he fell to his death from his ward at the twelfth floor. The clinical features, radiological findings and gross organ changes at autopsy closely simulated miliary tuberculosis. Histology, however, revealed extensive necrosis of the adrenal glands, lungs, spleen, kidneys and thyroid associated with the presence of Histoplasma capsulatum organisms. This case highlights the similarity both clinically and pathologically between histoplasmosis and tuberculosis and emphasizes the need to be aware of this infection in a nonendemic area among patients with a compromised immune system.
