Supplementary Material for: Disseminated histoplasmosis as a cause of a small bowel mass and cholestatic liver injury in an immunocompetent host – a case report

Disseminated histoplasmosis is a rare cause of granulomatous, cholestatic liver disease. It can also manifest with gastrointestinal (GI) tract involvement, usually with ulceration or mucosal thickening, but is rarely reported as a cause of mass lesions in the GI tract. It is also rare for disseminated histoplasmosis to present in an immunocompetent host. We present a case of cholestatic liver disease and a small bowel mass that has not previously been described in an immunocompetent host. Timely diagnosis requires a high index of suspicion, particularly if there has been exposure to high-risk environments, such as contaminated soils, as delayed diagnosis is associated with significant mortality.
