[Acanthosis nigricans maligna. Case report and review of the literature].

More than 400 cases of acanthosis nigricans maligna (ANM) and 23 cases of "florid cutaneous papillomatosis" (FCP) were published. ANM is an obligatory paraneoplastic symptom. A 28-year old female patient with an adenocarcinoma of the stomach presented with ANM. We review the number and types of associated cancer with ANM. In most cases and adenocarcinoma of the gastrointestinal tract has been present. We feel that FCP is not an entity of its own but a variant of ANM; the literature supports this view.
