Kimura disease: 2 case reports and a literature review.

Kimura disease (KD) is a chronic inflammatory soft-tissue disorder often presenting as swollen soft tissue or enlarged lymph nodes. KD is rare, and most reported cases have involved Asians. The pathogenesis is poorly understood, and treatments are unsatisfactory. KD is associated with allergic conditions such as asthma, rhinitis, and eczema. We present the cases of 2 patients treated for chronic endogenous eczema and KD in our dermatology clinic.
