The ultrastructure of lymphadenosis benigna cutis (pseudolymphoma cutis)

In an ultrastructural study supplementing previous histological, cytochemical and immunocytological investigations of lymphadenosis benigna cutis, the tumor is shown to consist mainly of two cell types: Lymphocytes and macrophagocytic (reticulum?) cells. The tendency to spontaneous regression is manifested on the ultrastructural level by pronounced degenerative alterations.
