Kimura's disease: a report of three cases with a brief review of literature.

Kimura's disease (KD) is an uncommon chronic inflammatory condition of unknown aetiology involving subcutaneous tissue, presenting as a tumor like lesion with a predilection for the head and neck region. Clinically it is often confused with parotid tumor with lymph node metastasis. It is difficult to diagnose before tissue biopsy. Fine needle aspiration cytology has only limited value. Unless the pathologists are aware of this entity, it might be misdiagnosed. Surgery, radiotherapy and steroid therapy have been tried but none is proved best and recurrence is common. Three cases of KD seen in our hospital and the problems encountered in them are presented.
