Primary malignant melanoma of the esophagus

A Rare and Rapidly Progressive Case of Primary Esophageal Malignant Melanoma in an Elderly Patient

Primary malignant melanoma of the esophagus (PMME) is a rare malignancy typically associated with poor prognosis, particularly in elderly patients. Here, we present the case of an 85-year-old female patient with a three-month history of progressive dysphagia and heartburn-related epigastric pain. Endoscopy revealed a polypoid esophageal lesion, confirmed as melanoma via biopsy with positive immunohistochemical staining for Melan-A and SOX-10. Given her age, frailty, and comorbidities, she was deemed unfit for surgery. A palliative approach, focusing on symptom management and systemic therapy, was adopted. Unfortunately, her condition rapidly worsened, leading to severe malnutrition and emaciation. The treatment focus shifted exclusively to symptomatic relief and best supportive care, and she ultimately passed away six months after diagnosis. PMME is rare and its diagnosis is challenging, especially in elderly patients; this case emphasizes the importance of individualized treatment plans. Early detection remains difficult due to the asymptomatic nature of early-stage disease. Treatment strategies are limited and should be carefully individualized, particularly in older patients, where the risks of aggressive intervention may outweigh potential benefits. In this group of patients, the emphasis should be placed on quality of life rather than curative intent.

The Thousand Faces of Malignant Melanoma: A Systematic Review of the Primary Malignant Melanoma of the Esophagus

Primary Malignant Melanoma of the Esophagus (PMME) is an extremely rare cancer of the esophagus, accounting for 0.1−0.8% of all oro-esophageal cancers and <0.05% of all melanoma subtypes, with an estimated incidence of 0.0036 cases per million/year. We conduct a careful analysis of the literature starting from 1906 to the beginning of 2022, searching the PubMed, Science.gov, Scopus and Web of Science (WoS) databases. A total of 457 records were initially identified in the literature search, of which 17 were duplicates. After screening for eligibility and inclusion criteria, 303 publications were ultimately included, related to 347 patients with PMME. PMME represents a very rare entity whose very existence has been the subject of debate for a long time. Over time, an increasing number of cases have been reported in the literature, leading to an increase in knowledge and laying the foundations for a discussion on the treatment of this pathology, which still remains largely represented by surgery. In recent times, the possibility of discovering greater mutations in gene hotspots has made it possible to develop new therapeutic strategies of which nivolumab is an example. Future studies with large case series, with clinicopathological and molecular data, will be necessary to improve the outcome of patients with PMME.
