Definition / general
  • Common in splenectomy specimens
  • Either:
    1. Large active granulomas with epithelioid and Langhans giant cells, with or without central necrosis
    2. Widespread small, sarcoid-like epithelioid granulomas with rare giant cells and no necrosis
    3. Inactive granulomas with fibrosis and calcification
  • Granulomas usually associated with systemic disease involving liver, bone marrow and lymph nodes; also chronic uremia, IgA deficiency, infectious mononucleosis
  • Granulomas may be present in hairy cell leukemia, Hodgkin lymphoma, non-Hodgkin lymphoma, although granuloma itself does not mean spleen is involved by tumor (Arch Pathol Lab Med 1977;101:518)
  • Active granulomas: in adults, associated with fever, weight loss, hepatosplenomegaly and hypersplenism
  • Inactive granulomas: associated with histoplasmosis
Treatment
  • Splenectomy for symptoms of hypersplenism
