ABSTRACT
Histoplasmosis is a fungal infection caused by the fungus Histoplasma capsulatum. It can manifest in various ways, ranging from pulmonary to disseminated presentations. Most of the disseminated cases are seen in immunocompromised patients; here, we present an unusual case of an 81-year-old Mexican male with a history of cave exposure in his childhood, with 75 years of incubation period of the disease, who developed disseminated cutaneous histoplasmosis with no evident immunocompromising conditions. We considered the hypotheses of transient immunosuppression, CD4+ T lymphocytopenia, and immune senescence as the cause of this manifestation. The present case is also notable for its recurrence following therapy. This report underscores the challenges in diagnosing histoplasmosis in immunocompetent individuals and highlights the importance of long-term treatment and follow-up.
