Clinical SummaryEdit

For four months before death, this two-year-old black female infant ate poorly and lost weight. When hospitalized, she appeared chronically ill with signs of infection. An exploratory laparotomy showed the patient had enormously enlarged abdominal lymph nodes, the biopsy of which disclosed active histoplasmosis. Despite intensive therapy, the patient died three weeks after admission.

Autopsy showed widespread enlargement of lymph nodes, ulcers of the intestines, and enlarged adrenal glands exhibiting multifocal granulomas.
