Kimura disease accompanied with nephrotic syndrome in a 45-year-old male.

Kimura disease (KD) is an uncommon chronic inflammatory disorder of unknown etiology, occurs mainly in Asian young males, presenting as subcutaneous growing masses, with a predilection for head and neck, with or without satellite lymphadenopathy. Herein, we report a case of an atypical manifestation of KD accompanied with NS in a middle-aged man, though the patient was clinically misdiagnosed previously. The diagnosis of KD can be difficult and misleading, so we must explore the main points of KD so as to prevent misdiagnosis.
