A Case of Recurrent Kimura Disease in the Groin Area / 대한내과학회지

ABSTRACT

Kimura disease is a rare chronic inflammatory disorder of unknown etiology, suggestive of an allergic or autoimmune mechanism, which presents mainly as soft tissue masses in the head and neck area in young Asian males. Blood tests show eosinophilia and an elevated immunoglobulin E; the typical pathologic findings are lymphoid follicular hyperplasia, interfollicular eosinophilic infiltration, and vascular hyperplasia. There is no standard treatment; surgical resection is preferred and systemic steroid or radiotherapy is used to treat disease relapses. Kimura disease in unusual sites has been reported, but there are few cases with long-term observations because of its benign nature. Here, we present the case of a female with recurrent Kimura disease; we follow her progress for about 5 years after surgical resection of masses in the right groin area, an unusual site, with a brief review of the literature.
