Titanium tetrachloride: an unusual agent with the potential to create severe burns.
Titanium tetrachloride (TiCl4), an intermediate compound in the production of white pigment, can cause severe burns. Two cases are reported in which TiCl4 created 18% to 20% total body surface area burns. These full-thickness injuries were the combined consequence of hydrochloric acid and the heat that was generated in areas where this otherwise stable compound was mixed with perspiration. TiCl4 combined with water is extremely dangerous, and its immediate treatment--towel drying before irrigation--makes it unique among chemicals. Our experience suggests that in most cases grafting will be required. These chemical burns were self-limited and had no notable systemic sequelae. Wound biopsy specimens taken on postburn days 3 and 6 were subjected to immunostaining that showed that TiCl4 did not retard wound healing. Exposure time to TiCl4 vapor will determine the pulmonary and ophthalmologic involvement in each case. Clinical awareness of the propensity of TiCl4 to react with water--even when that water is in the form of perspiration--is vital because prompt management can limit the extent of injury.
