title: [Study of hyperchromatism caused by benzene derivatives].
abstract: We report two patients with vitiligo-like lesions caused by contact with compounds containing phenols and toluene. The clinical, histopathologic and ultrastructural findings are compared with vitiligo. Two mechanisms may be present: one from direct enzymatic or cytotoxic action on melanocytes and the other through immunologic reaction.
