  19 October 2005

  Definition: Pulonary fungal infections due to Histoplasma capsulatum.
  Most examples of pulmonary histoplasmosis, including histoplasmoma and chronic histoplasmosis, are characterized by typical necrotizing granulomatous inflammation.
  Only disseminated histoplasmosis is recognized as causing a different reaction which consists of ingestion of organisms by macrophages without granuloma formation.

  Synopsis
  multiple foci of necrosis (#7149090#)
  fibrin thrombi within the microvasculature (#7149090#)
  Most lymphadenopathy is non-specific, caused by sinus expansion and paracortical zone enlargement, but there are also necrotic lesions of various sizes that can be surmised to result from ischaemic changes in some LNs.
  Necrotic foci start to develop immediately below the capsule, and are accompanied by fibrin thrombi in the small (...)
