[Annular erythema as the skin manifestation of primary Sjögren's syndrome--case report].

Annular erythema is a term used to identify skin lesions, in which the rash is erythema burgeoning peripherally and outgoing in the center. In this paper we present the case of 71-year old woman in whom diagnosis of possible causes of the development of annular erythema, led the team to identify primary Sjögren's syndrome (SS). Annular erythema was diagnosed on the basis of characteristic clinical picture and histopathological examination. Primary Sjögren's syndrome was diagnosed based on diagnostic criteria for primary SS and the exclusion of other autoimmune diseases. The patient in the study were the presence of characteristic subjective symptoms such as eye occurring for many years dry eyes and periodic feeling of sand in the eyes and dry mouth symptoms requiring frequent drinking of liquids to help swallow food. Changes within the eye was confirmed Schirmer's test, and the seizure of the salivary glands Saxon test. The serum showed the presence of autoantibodies Ro (SS-A) titer > 600 U/ml. The treatment recommended substitution of tears in order to protect the eye and the occasional use of preparations moisturizing mucous membrane of the nose and mouth. Due to the few reports of coexistence of annular erythema with primary Sjögren syndrome among Caucasians this case deserves special attention and calls for the implementation of diagnostic tests in each case, clinical suspicion of annular erythema in order to determine possible causes for its development.
