BACKGROUND: @entity110 is a common clinical condition whose etiology, in about 75% of cases, is unknown and is therefore called @entity14687 ( @entity14687 ). A link between @entity14687 and @entity1669 was proposed several decades ago. Here we review this topic. SUMMARY: Several studies have been performed to determine if and to what degree there is an association between @entity14687 and @entity1669 , particularly @entity1669 . Many of these studies were not well controlled, however. Approximately one-fourth of @entity14687 @entity1 have serological evidence of @entity1669 , suggesting that these two disorders are associated. The mechanisms for the apparent association between @entity14687 and serological evidence of @entity1669 are not clear. There are no data regarding the correlations between @entity14687 and histological features of @entity1669 or @entity1375 . Despite this, there are anecdotal reports regarding @entity1955 administration in @entity1 with @entity14687 . CONCLUSIONS: Screening for @entity1669 is probably useful in @entity1 with @entity14687 . More solid evidence, based on still lacking well-conducted controlled studies, is desirable to determine if there is a therapeutic role for @entity1955 treatment in ameliorating the skin manifestations of @entity110 .
