협부 파라핀종의 치험례

A paraffinoma of the cheek

Topical injection of dissolved paraffin or other mineral oils had been used to fill the tissue defect or to augment the tissue volume since early 1900s. It must be very handy to manipulate and to mold the injection site, but the easy success was followed by various complications as infection, skin necrosis, foreign body recation, neoplasmic change (paraffinoma), and Human Adjuvant diseases (HAD). The paraffinoma is defined as a foreignbody granuloma presenting the dispersed paraffin droplets with fibrosis. This is to report a case of paraffinoma occurred in the cheek of a 54-year old man who had been sufferred from cheek induration and cancer-phobia for 25 years. The clinical and histologic findings were as follows ; 1. The injected Paraffin was displaced lower, and infiltrated into the surrounding soft tissue spaces with marked calcified lipogranulomatous reaction. 2. Lipid materials with fibrosis were found dispersively in the surrounding tissues.
