Clinical SummaryEdit
This 33-year-old white female was admitted for evaluation of abnormal findings on a chest x-ray. She was asymptomatic and a physical examination revealed no significant abnormalities. Laboratory results indicated hypercalcemia and elevated gamma globulin. Radiographic examination showed enlarged subcarinal, hilar, and right paratracheal lymph nodes. A right paratracheal lymph node was biopsied. Special stains for acid-fast bacilli and fungi were negative and a diagnosis of sarcoidosis was made.

This is a photomicrograph of the small nodules (arrows) seen in the previous image. Close examination reveals that they are composed of large macrophages (epithelioid macrophages). These small granulomas form multiple series of reaction centers throughout the lymph node. Note the remaining lymphocytes surrounding the granulomas.
