[Immunoblastic sarcoma (reticulum-cell sarcoma) of the gastro-intestinal tract in a case of dermatitis herpetiformis Duhring (author's transl)].

In a 43-year-old man who for 20 years was known to have dermatitis herpetiformis there co-existed, since 1974, a "dermatogenic enteropathy" with gastro-intestional symptoms. Several small-intestine biopsies demonstrated severe partial to subtotal villous atrophy with crypt hyperplasia, as seen in gluten-sensitive enteropathy. At post-mortem there was an immunoblastic sarcoma - so-called reticulum-cell sarcoma - in the upper jejunum and abdominal lymph-nodes, which was presumably the immediate complication of the sprue-like lesions of the small intestines.
