title: [Malignant acanthosis nigricans: case report and literature review].
abstract: We present a senile patient that arrived as an outpatient because of marked pigmentation of his face and lower limbs and later develops ascites and loss weight. Biopsies of the skin showed the presence of Acanthosis Nigricans and we later showed its presence as a paraneoplastic syndrome when we discovered a gastric cancer. We discuss the association between Acanthosis Nigricans and cancer as well as the most common neoplasia that present with this entity.
