  lymphocyte-rich thymoma
  Definition: Type B1 thymoma closely resembles normal thymus cytologically and architecturally. It is usually an encapsulated mass with fibrous bands (seen here) separating it into nodules or lobules. It has areas resembling normal thymic cortex which are composed of scattered epithelial cells in a dense background of immature T-cells. Foci of medullary differentiation (seen here as lighter areas) with or without Hassall’s corpuscles are always present.

• Thymus in Langerhans histiocytosis
  15 January 2010

  Synopsis
  Extensive medullary infiltration by typical Langerhans histiocytes can be associated with active destruction of thymic epithelium, medullary pseudocysts, and prevalence of calcospherites, some of which were in Langerhans histiocytes.
  The presence of minimally affected Hassall bodies indicates that the thymus is probably normal prior to onset of disease.
  Destruction of thymic epithelium occurs regularly in Langerhans histiocytosis, but it may be an insignificant epiphenomenon (...)
