Metachronous presentation of metastatic melanoma and gastric adenocarcinoma

Abstract

Introduction: Synchronous multiple primary malignant tumors are relatively rare, although the number of patients diagnosed with multiple primary tumors is increasing, given the development of more sophisticated diagnostic procedures, and the increasing number of elderly patients. In recent years, there has been an exponential growth in the incidence of melanoma at an annual rate of 3 to 7% in Caucasian countries, and the frequency with which new malignancies associated with this tumor occur is considerable. Objective: To describe the Metachronous association of a patient with metastatic melanoma and gastric adenocarcinoma. Case Report: A 66-year-old patient with a history of having been diagnosed with malignant melanoma. He came to the clinic with an increase in volume in the left inguinal region. Associated with the presence of pain in the upper abdomen of moderate intensity. Metasynchronous presence of metastatic melanoma and gastric adenocarcinoma was diagnosed. The patient's evolution was not satisfactory and he died. Conclusions: The frequency with which a primary gastric tumor presents in a melanoma carrier is very low and therefore it is important to follow up those patients with melanoma and consider the risk of new neoplasms.
