Intra-Abdominal Malignant Melanoma: Challenging Aspects of Epidemiology, Clinical and Paraclinical Diagnosis and Optimal Treatment—A Literature Review. Diagnostics (Basel) 2022; 12:diagnostics12092054. [PMID: 36140455 PMCID: PMC9498106 DOI: 10.3390/diagnostics12092054] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2022] [Revised: 07/30/2022] [Accepted: 08/23/2022] [Indexed: 11/17/2022] Open
Abstract
According to European consensus-based interdisciplinary guidelines for melanoma, cutaneous melanoma (CM) is the most deadly form of dermatological malignancy, accounting for 90% of the deaths of skin cancer patients. In addition to cutaneous melanoma, mucosal melanoma occurs in four major anatomical sites, including the upper respiratory tract, the conjunctiva, the anorectal region, and the urogenital area. As this cancer type metastasizes, a classification used in the current medical literature is the distinction between secondary lesions and primary malignant melanoma of the abdominal cavity. Given that malignant melanoma is the most common cancer that spreads to the gastrointestinal tract, different imaging modalities compete to diagnose the phenomenon correctly and to measure its extension. Treatment is primarily surgery-based, supported by immunotherapy, and prolongs survival, even when performed at stage IV illness. In the end, special forms of malignant melanoma are discussed, such as melanoma of the genito-urinary tract and amelanotic/achromic melanoma. The importance of this present literature review relies on yielding and grouping consistent and relevant, updated information on the many aspects and challenges that a clinician might encounter during the diagnosis and treatment of a patient with intra-abdominal melanoma.

The Thousand Faces of Malignant Melanoma: A Systematic Review of the Primary Malignant Melanoma of the Esophagus. Cancers (Basel) 2022; 14:cancers14153725. [PMID: 35954389 PMCID: PMC9367585 DOI: 10.3390/cancers14153725] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Revised: 07/27/2022] [Accepted: 07/28/2022] [Indexed: 02/01/2023] Open
Abstract
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.

Abstract
Primary malignant melanoma of the esophagus (PMME) is a rare malignant neoplasm of the esophagus. In the majority of cases, the disease originates in the mucosal layer of the esophagus, which is similar to other types of esophageal cancer. With the development of endoscopic submucosal dissection (ESD), endoscopic resection is possible for cases in which melanomas are limited to the mucosal and submucosal layer. However, few studies report the efficiency of ESD for PMME, and no studies perform long-term follow-up. The present study reported the case of a 71-year-old PMME patient who was successfully treated by ESD at The Third Affiliated Hospital of Soochow University (Changzhou, China) in Otober 2011, with a follow-up of >3 years conducted.

Abstract
BACKGROUND Melanoma that involves the upper gastrointestinal (GI) tract is rare and studies relating to endoscopic and pathologic findings with clinical outcomes are lacking. We reviewed the gross and microscopic patterns of the upper GI tract in primary and metastatic melanoma, and examined their association with clinical outcomes. METHODS Twenty-nine cases of primary esophageal (n = 19) and metastatic gastric and/or duodenal melanoma (n = 10) that were detected during upper GI endoscopy between 1995 and 2011 were retrospectively analyzed. RESULTS Three types of gross patterns were recognized-nodular pattern in 7 cases, mass-forming pattern in 18 cases, and flat pigmented pattern in 4 cases. In primary esophageal melanoma, 13 patients (68.4 %) underwent surgery and 9 received palliative therapy. Of all cases, 22 patients (75.9 %) died of disease progression; the median overall survival period was 12 months (interquartile range [IQR] 4.5-24.5 months), and from recognition of upper GI tract melanoma the median overall survival period was 9 months (IQR 3.5-17.0 months). In primary esophageal cases, skin melanoma stage better discriminated the patients with good prognosis than the esophageal cancer stage. The flat pigmented gross pattern proved to be a good prognostic factor in primary and metastatic GI tract melanomas (p = 0.016 and p = 0.046, respectively). CONCLUSIONS Melanoma of the GI tract is a highly aggressive disease with a poor prognosis, both in primary and metastatic cases. However, in primary esophageal melanoma, careful inspection of the mucosa during endoscopic examination followed by surgical resection may result in extended survival.

Abstract
Primary malignant melanoma of the esophagus (PMME) comprises only 0.1–0.2% of all malignant esophageal tumors. PMME tumors are highly aggressive and metastasize early via hematogenic and lymphatic pathways. Treatment outcome is poor because the cancer has often advanced at the time of diagnosis. Inoperability, unsuccessful treatment with radiotherapy and chemotherapy in advanced tumors and metastases have contributed to its poor prognosis. Here, we present the endoscopic features, endoscopic ultrasonography findings and management of a PMME case.

Abstract
The authors present the clinical case of an 87-year-old Caucasian male admitted to the emergency room with hematemesis. He had a history of intermittent dysphagia during the previous month. Endoscopic evaluation revealed an eccentric, soft esophageal lesion located 25-35 cm from the incisors, which appeared as a protrusion of the esophagus wall, with active bleeding. Biopsies were acquired. Tissue evaluation was compatible with a melanoma. After excluding other sites of primary neoplasm, the definitive diagnosis of Primary Malignant Melanoma of the Esophagus (PMME) was made. The patient developed a hospital-acquired respiratory infection and died before tumor-directed treatment could begin. Primary malignant melanoma represents only 0.1% to 0.2% of all esophageal malignant tumors. Risk factors for PMME are not defined. A higher incidence of PMME has been described in Japan. Dysphagia, predominantly for solids, is the most frequent symptom at presentation. Retrosternal or epigastric discomfort or pain, melena or hematemesis have also been described. The characteristic endoscopic finding of PMME is as a polypoid lesion, with variable size, usually pigmented. The neoplasm occurs in the lower two-thirds of the esophagus in 86% of cases. PMME metastasizes via hematogenic and lymphatic pathways. At diagnosis, 50% of the patients present with distant metastases to the liver, the mediastinum, the lungs and the brain. When possible, surgery (curative or palliative), is the preferential method of treatment. There are some reports in the literature where chemotherapy, chemohormonotherapy, radiotherapy and immunotherapy, with or without surgery, were used with variable efficacy. The prognosis is poor; the mean survival after surgery is less than 15 mo.

Abstract
Malignant melanoma is one of the most common malignancies to metastasize to the gastrointestinal (GI) tract. Metastases to the GI tract can present at the time of primary diagnosis or decades later as the first sign of recurrence. Symptoms may include abdominal pain, dysphagia, small bowel obstruction, hematemesis, and melena. We report 2 cases of malignant melanoma metastatic to the GI tract, followed by a review of the literature. The first case is a 72-year-old man who underwent resection of superficial spreading melanoma on his back 13 years previously who presented with dysphagia. A biopsy specimen of a mucosal fold in a gastric fundus noted during endoscopy was taken and revealed metastatic malignant melanoma, which was resected 1 month later. Three weeks later, the patient was found to have an ulcerated jejunal metastatic melanoma mass, which was also resected. The second case is a 63-year-old man with an ocular melanoma involving the chorold of the left eye that had been diagnosed 4 years previously, which had been excised several times, who presented with anorexia, dizziness, and fatigue. He was found to have cerebellar and stomach metastases. He underwent adjuvant radiation therapy, chemotherapy, and surgical resection of the gastric melanoma metastasis. In patients with a history of melanoma, a high index of suspicion for metastasis must be maintained if they present with seemingly unrelated symptoms. Diagnosis requires careful inspection of the mucosa for metastatic lesions and biopsy with special immunohistochemical stains. Management may include surgical resection, chemotherapy, immunotherapy, observation, or enrollment in clinical trials. Prognosis is poor, with a median survival of 4 to 6 months.
