Necrobiosis lipoidica occurs in association with systemic diseases (sarcoidosis, autoimmune thyroiditis, inflammatory bowel disease, such as ulcerative colitis, and rheumatoid arthritis) and can also occur in otherwise healthy individuals. Necrobiosis lipoidica is closely associated with diabetes mellitus.</p> <p>The predominant localization of necrobiosis lipoidica is tibial surface of the legs. Atypical localization is: skin of the scalp and face.</p> <p>Clinical polymorphism of necrobiosis lipoidica, possibility of transition from one form to another, its combination with other dermatoses can pose difficult diagnostic questions for the doctor.</p> <p>The article describes our own clinical observation of a patient with complaints of rashes on the skin of the legs and scarring alopecia in the scalp. The focus on the scalp had a tendency to grow and signs of development of scarring alopecia. According to the results of a biopsy performed at the Rakhmanov Department of Skin and Veneral Diseases, I.M. Sechenov First Moscow State Medical University, was diagnosed with "Necrobiosis Lipoidica". The case was interesting due to the extreme rarity of rashes on the skin of the scalp and the absence of dermatoscopic features of lesions in this area. Due to ongoing therapy for a month, there was a positive effect in the form of a lack of growth of existing plaques and the appearance of new ones, a decrease in the brightness of the color of the rash, a partial regression with an outcome in residual hyperpigmentation.</p> <p>Thus, despite the absence of a gold standard in the treatment of necrobiosis lipoidica, the most well-studied group of drugs for the treatment of the disease at the moment are glucocorticoids, which confirms our experience. Therapy of patients with necrobiosis lipoidica should be carried out by an interdisciplinary team (dermatovenereologist, endocrinologist, therapist).</p></abstract><trans-abstract xml:lang="ru"><p>Липоидный некробиоз ― хроническое гранулематозное заболевание кожи сосудисто-обменного характера из группы локализованных липоидозов кожи, сопровождающееся дегенеративными изменениями соединительной ткани.</p> <p>Причина развития липоидного некробиоза неизвестна, однако наиболее распространённой остаётся теория сосудистых нарушений, включающих отложение иммунных комплексов (IgМ, С3-компонент комплемента), микроангиопатические изменения (отложение гликопротеина в стенках сосудов), а также другие комбинации воспалительных и структурных изменений, приводящие к дегенерации коллагена и снижению перфузии и оксигенации кожи. Липоидный некробиоз сочетается с системными заболеваниями (саркоидоз; аутоиммунный тиреоидит; воспалительные заболевания кишечника, например язвенный колит, ревматоидный артрит), в том числе может развиваться у соматически здоровых лиц. Часто липоидный некробиоз ассоциируется с сахарным диабетом.</p> <p>Преимущественная локализация очагов липоидного некробиоза ― область голеней. Атипичной локализацией считаются кожа волосистой части головы и лицо.</p> <p>Клинический полиморфизм липоидного некробиоза, возможность перехода одной формы в другую, его сочетание с другими дерматозами могут ставить перед врачом сложные диагностические вопросы.</p> <p>В статье приводится описание собственного клинического наблюдения пациента с жалобами на высыпания на коже голеней и рубцовую алопецию в области волосистой части головы. Очаг на волосистой части головы имел тенденцию к росту и признаки развития рубцовой алопеции. По результатам биопсии был выставлен диагноз липоидного некробиоза. Случай был интересен крайней редкостью высыпаний на коже волосистой части головы и отсутствием дерматоскопических особенностей очагов в этой области. На фоне проводимой терапии в течение месяца наблюдалась положительная динамика.</p> <p>Таким образом, несмотря на отсутствие золотого стандарта в терапии липоидного некробиоза, наиболее хорошо изученной группой препаратов для лечения заболевания на данный момент являются глюкокортикоиды, что и подтверждает наш опыт. Терапия пациентов с липоидным некробиозом должна осуществляться междисциплинарной командой (дерматовенеролог, эндокринолог, терапевт).</p></trans-abstract><kwd-group xml:lang="en"><kwd>necrobiosis lipoidica</kwd><kwd>necrobiosis lipoidica/diagnosis</kwd><kwd>necrobiosis lipoidica/therapy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>липоидный некробиоз</kwd><kwd>кожный дислипоидоз</kwd><kwd>терапия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Olisova OY, Teplyuk NP.
