Pathologic supracondylar fracture due to osteolytic pseudotumor of knee following cementless total knee replacement

Kimura's Disease, a rare chronic inflammatory disorder with a benign course affecting the lymphoid tissue is reported hare in an 18 year old South Indian male who presented with bilateral solitary swelling over the mastoid region. Its fine needle aspiration cytology characterised by the Warthin-Finkeldey type giant cells against a background of a bimodal population of lymphocytes and eosinophils prompted the diagnosis of Kimura's disease at cytology itself. This was confirmed at histology. This is the third cytological report of its kind being reported in English literature. Literature with regard to the cytological appearances of Kimura's disease has been reviewed and the various differential diagnoses discussed.
