TCP Hand

TCP hand plain xray

This manual worker presented to the minor injuries unit following an accident at work, for which he received first aid before attending hospital. This high density area over the soft tissues of the hand was apparent. He has not been in contact with radiological contrast agents.

The appearances were due to the generous use of TCP retained within a cavity in the soft tissues of the hand. TCP is a longstanding mild antiseptic product popular in medicine cabinets, being widely used for a range of first aid purposes, including on cuts and grazes. TCP is named after its original chemical composition, which was trichlorophenylmethyliodosalicyl (TCP). The current active ingredients include halogenated phenols, one of which is iodinated phenol.
