Erythema nodosum and conjunctivitis triggered by enteritis due to Salmonella typhimurium.

We describe a patient, a 59-year-old woman, who developed erythema nodosum and conjunctivitis after enteritis due to Salmonella typhimurium. The patient was HLA-B27 negative and had circulating immune complexes, as determined by the conglutinin-binding enzyme immunoassay. Immunopathogenesis of the extraintestinal findings is discussed.
