Проведен анализ литературных источников и представлен случай, демонстрирующий трудности диагностики неходжкинской Т-клеточной лимфомы. Результаты и их обсуждение. Пациент З., 56 лет, поступивший в многопрофильный стационар с диагнозом «Острая токсикодермия. Синдром Стивенса–Джонсона?», в течение 10 лет наблюдался у дерматолога по поводу дерматита. За 1 месяц до госпитализации  отметил высыпания на коже всего тела с образованием  болезненных пузырей, выраженную слабость, повышение температуры тела, затруднение глотания, боли в суставах. Несмотря на проводимое лечение (преднизолон, меропенем, линезолид, флуконазол), состояние ухудшалось с развитием полиорганной недостаточности и летальным исходом. Аутопсия выявила Т-клеточную периферическую неспецифицированную лимфому и обострение хронического дерматоза.</p></sec><sec><title>Выводы</title><p>Выводы. Приведенный случай подтверждает агрессивное течение и неблагоприятный прогноз периферической Т-клеточной лимфомы, указывая на неудовлетворительные результаты стандартной терапии. Манифестация заболевания с гипертермией, полиартралгией и изменениями на коже затрудняла диагностику лимфомы, что частично было обусловлено недостаточной осведомленностью и онкологической настороженностью врачей-терапевтов, дерматологов в отношении онкогематологической патологии. Случай демонстрирует целесообразность иммуногистохимического исследования биоптата зоны повреждения, определения объема лимфопролиферативного поражения костного мозга и определения тактики ведения пациентов. </p></sec></abstract><trans-abstract xml:lang="en"><p>Some progress has been made in the study of the pathogenesis of peripheral T-cell lymphomas, which account for 10–15% of all non-Hodgkin’s lymphomas; however, diagnosis is diffi  cult due to their rare occurrence and clinical and morphological diversity.</p><sec><title>Aim</title><p>Aim. to present data on the clinical course of peripheral T-cell lymphoma using a clinical example of patient Z.</p></sec><sec><title>Material and methods</title><p>Material and methods.

Patient Z., 56 years old, treated in a multidisciplinary hospital with the diagnosis of “Acute toxicoderma. Stevens–Johnson syndrome?” had been under the care of a dermatologist for dermatitis for 10 years. One month prior to hospitalization, he developed a skin rash covering his entire body with blistering, soreness, severe weakness, fever, difficulty swallowing, and joint pain. Despite treatment (prednisolone, meropenem, linezolid, fluconazole), the patient’s condition worsened, leading to multiple organ failure and death. Postmortem biopsy revealed peripheral T-cell lymphoma of unspecifi ed type and exacerbation of chronic dermatosis.</p></sec><sec><title>Conclusions</title><p>Conclusions. This case confirms the aggressive course and poor prognosis of peripheral T-cell lymphoma, highlighting the unsatisfactory results of standard therapy. The disease’s onset, with hyperthermia, polyarthralgia, and skin changes, complicated the diagnosis of lymphoma, partly due to the lack of awareness and oncologic suspicion of oncohematological pathology among general practitioners and dermatologists. This case demonstrates the usefulness of immunohistochemical examination of the lesion biopsy, determining the extent of lymphoproliferative bone marrow lesions, and determining patient management strategies. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Т-клеточная лимфома</kwd><kwd>маски</kwd><kwd>прогноз</kwd><kwd>клинический случай</kwd></kwd-group><kwd-group xml:lang="en"><kwd>T-cell lymphoma</kwd><kwd>masks</kwd><kwd>prognosis</kwd><kwd>clinical case</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">Нодальные Т-клеточные лимфомы.
