== Clinical Summary ==
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.

File:IPLab10Histo1IPLab10Histo1b.jpg|This low-power photomicrograph shows a section of adrenal gland with several irregularly-outlined areas of necrosis.
File:IPLab10Histo2.jpg|This higher-power photomicrograph of the previous adrenal gland shows more clearly the irregularly-shaped area of necrosis (arrows).
File:IPLab10Histo3.jpg|This is an even higher-power photomicrograph of an area of necrosis (arrows). There is loss of cellular detail within this area. There are inflammatory cells present; however, it is difficult to differentiate the inflammatory cells from the native lymphocytes of the adrenal gland--which is a lymph node.
