A usual cause of tumoural mass of the index finger.

We present a case of an unusual appearance of a tumoural mass on the right index finger. A 52-year-old farmer was administered to our outpatient clinic due to a large tumoural mass in his right index finger. He has been reporting of the mass for 32 years. Upon examination there was a rubbery soft, fixed, painless tumoural mass on the right index finger, covering all proximal phalanx volar and dorsal causing no surface skin reaction. The entire mass was excised and sent for pathological examination. The pathological result was a fatty degenerated fibroma. This kind of tumour may easily be misinterpreted as a lipoma even radiologically. So it is believed that any surgeon should always be suspicious of the diagnosis of long-term masses of any kind. 2014 BMJ Publishing Group Ltd.
