Kimura's Disease of the Distal Arm: A Case Report

ABSTRACT

Kimura's Disease is a very rare, chronic inflammatory disorder with an unknown etiology, and this illness is primarily seen in young Asian males. The typical clinical features consist of painless subcutaneous masses in the head or neck region, and especially in the salivary gland and submandibular region. It is often accompanied with a regional lymphadenopathy, peripheral blood eosinophilia and elevated serum IgE levels. Histologically, it is characterized by prominent germinal centers in the involved lymph nodes, together with eosinophilic infiltration in these lymph nodes. The treatment modalities for this disease are steroid therapy, radiation therapy and surgical excision. Its clinical course is of a benign nature. We report here on a case of a 28 year old man who had a soft tissue mass in his left arm. We excised this mass and the microscopy confirmed that he suffered from Kimura's disease on microscopic examination in his left distal arm.
