Bilateral adrenal histoplasmosis presenting as adrenal insufficiency in an immunocompetent host in the Philippines


Disseminated histoplasmosis, with the adrenal glands as being the only site of demonstrable disease in an immunocompetent adult, is a rare infection leading to adrenal insufficiency. This disease carries high mortality when unrecognised. We describe the first reported case of adrenal histoplasmosis in the Philippines in a 72-year-old immunocompetent, Filipino man who presented with a 3-month history of intermittent flank pain, weight loss and generalised weakness. His imaging demonstrated bilateral adrenal masses on ultrasonography and contrast-enhanced CT scan. The initial impression was adrenal cancer, however, fine-needle aspiration cytology revealed the presence of yeast cells and blood culture grew Histoplasma capsulatum. The diagnosis of the case represents a diagnostic challenge in immunocompetent individuals because they manifest with non-specific symptoms. A heightened suspicion is therefore needed to prevent significant morbidity and mortality.
