Abstract
Chemical leukoderma is seen in a variety of clinical settings. We present a case of leukoderma associated with the phenolic derivative thymol found in a common over-the-counter medication for nasal congestion. The proposed mechanism for this type of leukoderma is presented along with other sources of phenolic and catecholic derivatives. Treatment is also briefly reviewed.
