TENOSYNOVIAL GIANT CELL TUMOUR ON DORSAL ASPECT OF FINGER: A RARE PRESENTATION

Tenosynovial giant cell tumour is considered to be a benign hyperplastic lesion occurring due to probably chronic antigenic inflammatory process. Its nodular form has a propensity towards tendon sheaths. However tendon sheath of dorsal aspect as in the presented patient is rare. Hence when a 35 years female presented with a firm slowly enlarging nodule on index finger with no bony involvement. It was excised with a margin of normal tissues as well. Histopathological examination confirmed it to be a tenosynovial giant cell tumour. Patient has shown no recurrence on 2 years follow up.
