Kimura’s disease: A short study of cytomorphologic features with its differential diagnosis and review of literature

Kimura’s disease (KD) is a chronic inflammatory disorder of unknown etiology, endemic in Asia. The typical clinical manifestations include a triad of painless unilateral cervical lymphadenopathy or subcutaneous masses predominantly in the head-and-neck region, blood and tissue eosinophilia, and elevated serum immunoglobulin (Ig) E levels. Many conditions including benign and malignant may mimic KD clinically. This study reports cytologic features of seven cases of KD which were studied and correlated with histology, Ig profile, and peripheral blood examination. KD shows a good response to medical treatment; hence, fine-needle aspiration cytology in conjunction with other laboratory findings lowers the need for additional biopsy procedures for early diagnosis as well as diagnosis of recurrent lesions.
