Hexachlorophene Storage in a Burn Patient Associated With Encephalopathy

Abstract

Hexachlorophene (HCP), a chlorinated phenolic hydrocarbon with bacteriostatic properties against Staphylococcus, is used in a number of topical products. Absorption through normal and damaged human skin has been appreciated and neurologic changes have been described in experimental animals, but instances of human toxicity have been reported infrequently. A 10-year-old boy who sustained a 25% burn did well initially but died in the second week of convalescence with hyperthermia, lower-extremity weakness, and cerebral edema. His treatment had included frequent applications of HCP. Analysis of post-mortem tissue revealed the presence of toxic levels of HCP in the blood (2.2 mug/gm) and brain (2.2 mug/gm), with storage in skin (25 mug/gm), liver (4.4 mug/gm), and fat (6.0 mug/gm). This case suggests that topical applications of HCP in man may result in an extensive absorption with fat storage and may cause fatal encephalopathy.
