Annually from 3 to 10 cases of pyoderma gangrenosum per million people are reported. To the present time, the etiology and pathogenesis of pyoderma gangrenosum remain completely unstudied, and the diagnosis is complicated by the rare incidence of the disease and non-specificity of cutaneous manifestations.</p> <p>In this article the observation of a long-term course of pyoderma gangrenosum in a 58-year-old female with ulcerative colitis and multiple endocrine neoplasia type I. The differential diagnosis between pyoderma gangrenosum with necrotising ulcerative vasculitis was performed. Based on the results of the comprehensive examination, the final diagnosis of pyoderma gangrenosum was established.</p> <p>This clinical observation demonstrates the necessity for the detailed examination of patients in order to make a correct diagnosis and prescribe adequate treatment on time.</p></abstract><trans-abstract xml:lang="ru"><p>Дифференциальный диагноз хронических язв неинфекционной природы остаётся сложной междисциплинарной проблемой.</p> <p>Гангренозная пиодермия ― редкое аутовоспалительное заболевание, которое относится к группе нейтрофильных дерматозов и клинически проявляется быстрым развитием болезненных, длительно персистирующих, рецидивирующих кожных язв с неровными, подрытыми краями багрово-фиолетового цвета и окружающей эритемой. Ежегодно выявляются от 3 до 10 случаев гангренозной пиодермии на 1 млн человек. До настоящего времени этиология и патогенез гангренозной пиодермии до конца не изучены, при этом диагностику затрудняют редкая встречаемость патологии, а также возможность построения довольно широкого дифференциального ряда с учётом клинико-гистологического многообразия заболевания, в том числе васкулитов с относительно схожими клиническими проявлениями.</p> <p>В настоящей статье представлено наблюдение длительного течения гангренозной пиодермии у пациентки в возрасте 58 лет с язвенным колитом и множественной эндокринной неоплазией I типа. Дифференциальную диагностику заболевания проводили с некротическим язвенным васкулитом. По результатам всестороннего обследования пациентке установлен окончательный диагноз: «Гангренозная пиодермия».</p> <p>Представленное клиническое наблюдение демонстрирует необходимость подробного обследования пациентов с целью постановки правильного диагноза и своевременного назначения адекватного лечения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>pyoderma gangrenosum</kwd><kwd>case report</kwd><kwd>ulcerative colitis</kwd><kwd>multiple endocrine neoplasia type I</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гангренозная пиодермия</kwd><kwd>клинический случай</kwd><kwd>язвенный колит</kwd><kwd>множественная эндокринная неоплазия I типа</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Grabovskaya OV, Teplyuk NP, Kusraeva DT, Varshavsky VA.
