LICHEN-PLANUS PIGMENTOSUS ASSOCIATED WITH ACROKERATOSIS OF BAZEX

A patient with an acquired pigmentation related to lichen planus pigme ntosus is described. Features of acrokeratosis of Bazex were associate d, related to a head and neck carcinoma. Both cutaneous conditions dis appeared after treatment of the neoplasia. Diagnostic criteria of lich en planus pigmentosus are reviewed. The paraneoplastic nature of this original observation of lichen planus pigmentosus is discussed. Acroke ratosis of Bazex is a classical example of a paraneoplastic condition. Lichen planus, usually the vesiculobullous variant, has been reported in association with underlying malignancies.(1) A few years ago, we o bserved a patient who developed simultaneously lichen planus pigmentos us and associated acrokeratosis of Bazex. Treatment of an associated h ead and neck cancer caused resolution of both diseases. Long-term foll ow-up of the patient and review of the literature prompted us to prese nt this case-report. To our knowledge, the association of these two co nditions has not so far been reported.
