Данный тип неоплазии трудно диагностируется и характеризуется быстрым прогрессированием, высоким риском рецидивов и метастазирования. Несмотря на диагностические возможности рентгенологических методов исследования, которые позволяют выявить опухоль и определить ее локализацию, правильный диагноз может быть установлен только при эндоскопическом исследовании верхних отделов пищеварительного тракта с биопсией и последующими патоморфологическим и иммуногистохимическим исследованиями. Пациент И., 78 лет был направлен в МНИОИ им. П. А. Герцена с подозрением на рак пищевода. Из анамнеза известно, что больной в течение 6 месяцев отмечал нарушение прохождения твердой пищи, дискомфорт в области грудной клетки. На основании данных проведенной экспертной эзофагогастродуоденоскопии нами было выдвинуто предположение о наличии у пациента первичной меланомы пищевода со смешанной формой роста - экзофитной и плоской. Согласно результатам морфологического исследования биоптатов, в обоих фрагментах ткани верифицирована пигментная эпителиоклеточная меланома пищевода с высокой митотической активностью (до 3 фигур митозов в 1 кв.мм) и инфильтративным ростом. Данное клиническое наблюдение демонстрирует важность проведения детального эндоскопического исследования и выполнения таргетированной биопсии с последующим экспертным патоморфологическим исследованием при дифференциальной диагностике заболеваний пищевода, характеризующихся пигментацией его слизистой оболочки.</p></abstract><trans-abstract xml:lang="en"><p>Primary malignant melanoma of the esophagus is defined as a tumor, the frequency of which is 0.1-0.2% of all malignant lesions of the esophagus. This type of neoplasia is difficult to diagnose and is characterized by rapid progression, high recurrence rate and metastasis. Despite the diagnostic capabilities of X-ray examination methods, which make it possible to identify a tumor and determine its localization, the correct diagnosis can only be established by endoscopic examination of the upper digestive tract with biopsy and subsequent pathological and immunohistochemical studies. A 78 year-old male patient was admitted to the Herzen Moscow State Medical Institute with suspected esophageal cancer. It is known from the anamnesis, that the patient for 6 months notes a dysphagia, pain in the chest area. Based on the data of our expert endoscopic examination, we suspected primary esophageal melanoma with a mixed growth - exophytic and flat-type. According to the results of pathological examination of the biopsies, pigment epithelial-cell melanoma of the esophagus with high mitotic index (up to 3 mitosis figures per 1 sq.mm) with infiltrative growth type. This clinical case demonstrates the importance of a detailed endoscopic examination and performing a targeted biopsy, followed by expert pathological examination in the differential diagnosis of esophageal diseases characterized by pigmentation of mucosa.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>первичная меланома пищевода</kwd><kwd>эзофагогастродуоденоскопия</kwd><kwd>редкая опухоль пищевода</kwd></kwd-group><kwd-group xml:lang="en"><kwd>primary malignant melanoma of the esophagus</kwd><kwd>upper endoscopy</kwd><kwd>rare oesophageal tumor</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Schizas D., Mylonas K.
