[Hyperpigmentation of the Laugier-Hunziker-syndrome type appearing during antineoplastic polychemotherapy].

The Authors report a case of multiple brown slate macules localized on the lips and on the oral mucosa, occurred to a 66 year-old woman during cancer polychemotherapy with cis-diamminedichloroplatinum and Cyclophosphamide due to an ovary's serous cystadenocarcinoma with peritoneal metastasis. The histological test taken on a lip's lesion, fully excised, points out main focal hyperpigmentation of basal epidermal layer and numerous melanophages in the papillary dermis. The Authors, after a comparison among the information obtained from the literature, exclude any possible secondary reaction due to chemotherapy or any paraneoplastic syndrome. What they emphasize is the great similarity between the clinical and histological pictures noticed in this case and the ones described in the Laugier-Hunziker's syndrome. The particular association observed in this case is noteworthy but, nowadays following the existing knowledges, no relation of cause and effect between polychemotherapy, cancer and Laugier-Hunziker's disease can be advanced.
