Dermatitis herpetiformis and leiomyomas with HLA-B8, a marker of immune diseases

Multiple cutaneous leiomyomas and dermatitis herpetiformis (DH) were found in the same patient. This association has not been previously described, although the association of malignant tumours and DH is well known. HLA-B8 was found in this patient as well as in an older brother with polymyositis; this antigen is known to be associated with other immune diseases.
