[Generalized lymph node sarcoma during course of an actinic reticuloid (author's transl)].

A 50 year old man with actinic reticuloid developed a diffuse malignant lymphoma 7 years after the beginning of the dermatosis. Biopsy of lymph node showed a polymorphic proliferation with lymphocytes, numerous reticular cells and several Sternberg-like cells. An ultrastructural study showed an indifferentiate lymphocyte proliferation and numerous malignant reticular cells without the Sternberg cell picture.
