FNAC Diagnosis of a Giant Cell Tumour of Soft Tissue with Histological Correlation Over Right Angle of Mandible

Giant Cell Tumor (GCT) of the soft tissue is locally aggressive and relatively uncommon neoplasm. It occurs predominantly in upper and lower extremities in 70% of the cases. It is rarely seen in the head and neck region which accounts for around 7% of the cases. Patients may present usually with a painless growing mass, over an average period of six months duration, in their fifth decade of life. Fine needle aspiration cytology (FNAC) may not be diagnostic because of other chronic inflammatory and infective conditions which also show giant cells on FNAC. The differential diagnoses are foreign body giant cell reaction, tuberculosis, sarcoidosis etc. Confirmatory diagnosis depends predominantly on the histomorphology of the lesion.
