[Desmoid cervical tumour following the placing of an internal jugular catheter]

A desmoid tumour is a rare fibroblastic tumour and generally located in the abdomen. However, it can also develop on surgical scars.

A 36 year-old woman on chronic dialysis consulted for a cervical mass on the left side that was progressively increasing in volume, on the site of a scar of an internal jugular catheter placed 7 months earlier. Histological analysis of a sample of this mass concluded in a benign fibroblastic proliferation and led to the diagnosis of a desmoid tumour. Study of the patient's history revealed that a left jugular catheter had been placed on two occasions to be used for the hemodialysis approach, the lesion provoked by the latter would explain the development of the desmoid tumour.

The potential severity of this tumour is related to its proximity with the carotid, trachea and base of the skull. In general, desmoid tumours, rare benign tumours of the connective tissue, exhibit a complex multifactor etiopathogenesis. A surgical trauma can often trigger-off such tumours.
