Ileocecal histoplasmosis mimicking Crohn's disease in a patient with Job's syndrome

Digestion. 1986;33(3):176-80. doi: 10.1159/000199290.


A 16-years-old male with a history of Job's syndrome and a recent diagnosis of Crohn's disease was admitted to the hospital because of abdominal pain, nonbloody diarrhea, weakness, and fever. Due to failure to respond to medical therapy it was decided that an operation was indicated, and resection of the terminal ileum and right colon was performed. Cecum and ileum were inflamed, and pathologic studies revealed the presence of budding yeasts which on special stain were diagnostic of Histoplasma species. Successful management was accomplished with oral ketoconazole.
