title: Acanthosis nigricans and wart-like lesions associated with metastatic carcinoma of the stomach.
abstract: A 63-year-old white man developed malignant acanthosis nigricans one year after a hemigastrectomy for adenocarcinoma of the stomach. Multiple "wart-like" lesions involving the dorsa of the hands, arms and trunk were also present. The malignant acanthosis nigricans in the patient appears to have paralledled the course of the metastatic gastric adenocarcinoma. Discrete verrucous lesions can occur in malignant acanthosis nigricans which histopathologically may show either squamous or basal cell hyperplasia.
