Cells containing Langerhans granules in human lymph nodes of dermatopathic lymphadenopathy.

Abstract

Cells containing Langerhans granules are found in human lymph nodes of dermato-pathic lymphadenopathy. The ultrastructural characteristics of these cells are identical to the epidermal Langerhans cells of the same patients. The possible development of Langerhans cells from mesenchymal tissues is discussed.
