Кожные метастазы являются результатом инфильтрации кожи за счет пролиферации клеток отдаленно расположенных злокачественных опухолей, встречающихся с частотой 0,6–10,4 % при различных онкологических процессах. Они могут быть признаком прогрессирующего новообразования или являться проявлением впервые диагностированного рака. Ограниченное количество статей включают в себя описание клинических и дерматоскопических признаков метастатических узлов солидных опухолей. Это связано с большой вариабельностью клинических проявлений, приводящей к диагностическим ошибкам.</p></sec><sec><title>Цель исследования</title><p>Цель исследования: разобрать клинические и дерматоскопические особенности кожных метастазов рака молочной железы.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Пациентка с жалобами на незначительные болевые ощущения и зуд в области образований на коже волосистой части головы. Из анамнеза: в 2012 году по поводу рака правой молочной железы была выполнена мастэктомия справа с последующей гормональной терапией, которую пациентка самовольно прекратила. Учитывая нехарактерную локализацию, ограниченную волосистой частью головы, проводился дифференциальный диагноз между цилиндромой, множественным базальноклеточным раком и метастазами карциномы. С целью уточнения диагноза была выполнена биопсия.</p><p>Результаты и обследование. Патологический кожный процесс был представлен множественными узлами до 2 см в диаметре, розоватого цвета, плотными, безболезненными при пальпации, без четких границ. Дерматоскопически: полиморфные сосуды на эритематозном фоне, структуры по типу хризолит. По данным гистологического и иммуногистохимического исследований были верифицированы метастазы рака молочной железы.</p></sec><sec><title>Заключение</title><p>Заключение. Кожные метастазы могут быть первым признаком рецидива злокачественной опухоли. Дерматоскопия может облегчить их дифференциальную диагностику с другими заболеваниями кожи. Прогностически значимы плотность и диаметр патологических сосудов. При выявлении образований, не укладывающихся в стандартную клиническую картину новообразований кожи, целесообразно выполнение гистологической верификации диагноза.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Skin metastases are the result of skin infiltration caused by the proliferation of cells of remotely located malignant tumors occurring with a frequency of 0.6–10.4 % in various oncological processes. They may be a sign of progressive neoplasm or a manifestation of newly diagnosed cancer. Due to a high variability of clinical manifestations leading to misdiagnoses, a limited number of articles describe clinical and dermatoscopic signs of solid tumors metastatic nodes. Aim: to analyze the clinical and dermatoscopic features of skin metastases from breast cancer.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A female patient has complaints of slight pain and itching in the lesions area on the scalp. According to her medical history, a right mastectomy was performed for right breast cancer in 2012, followed by hormone therapy willfully discontinued by the patient. Given the uncommon localization limited with the scalp, the differential diagnosis was made with a spectrum between a cylindroma, multiple basal cell cancer and metastatic carcinoma. A biopsy was carried out to confirm the diagnosis. Results and examination. The pathological skin process revealed itself through multiple nodes up to 2 cm in diameter, pinkish in color, dense, painless on palpation, poorly demarcated. Dermatoscopically: polymorphic vessels on an erythematous background, chrysalis-like structures. Breast cancer metastases were verified by histological and immunohistochemical examination.</p></sec><sec><title>Conclusion</title><p>Conclusion. Skin metastases may be the first sign of cancer recurrence. Dermatoscopy can facilitate differenting them from other skin diseases. Density and diameter of pathological vessels are prognostically significant. Ifdetected lesions do not fit the standard pattern of skin neoplasms, histological verification of the diagnosis is recommended to be carried out.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>новообразований метастазы</kwd><kwd>кожные проявления</kwd><kwd>дерматоскопия</kwd><kwd>гистологические методы</kwd><kwd>иммуногистохимия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>neoplasms metastases</kwd><kwd>skin lesions</kwd><kwd>dermatoscopy</kwd><kwd>histological methods</kwd><kwd>immunohistochemistry</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">Globocan 2020: New global cancer data.
