Autoimmune thyroid disease in anti-Ro/SS-A-positive children with annular erythema: report of two cases.
Anti-Ro/SS-A-associated recurrent annular erythema is a rare disorder, and represents a cutaneous manifestation of primary Sjögren's syndrome (SS). We report two childhood cases complicated with autoimmune thyroid disease, one with Graves' disease and the other with autoimmune thyroiditis. Both children were positive for anti-Ro/SS-A and anti-La/SS-B antibodies. One patient was lacking clinical SS with objective evidence of salivary gland involvement, while the other was diagnosed with primary SS. Our observation suggests that autoimmune thyroid disease in the subset of anti-Ro/SS-A-positive children with annular erythema might occur with similar frequency to that in adult primary SS.
