An unusual case of extra-abdominal desmoid tumour of the finger

Extra-abdominal desmoid tumour is a rare tumour and involvement of the finger is extremely rare. These are generally non-metastasizing lesion of mesenchymal origin composed of fibrous tissue with locally aggressive proliferative behaviour. We report a case of extra-abdominal desmoid in a sixty year year old lady involving the right index finger. The swelling was slowly increasing in size over a period of eleven years and involved almost the entire length of the finger. A disarticulation at the second metacarpophalangeal joint was done and histopathological examination confirmed it to be a desmoid tumour
