Подногтевой экзостоз представляет собой разрастание костной и/или хрящевой ткани в области дистальной фаланги пальца. Этиопатогенез заболевания остается не до конца изученным. Считается, что в развитии подногтевого экзостоза принимают участие множество как экзогенных, так и эндогенных факторов. Эпидемиология заболевания также остается не до конца изученной с противоречивыми данными о его гендерных и возрастных особенностях. Чаще всего отмечается поражение первых пальцев стоп. Несмотря на то, что подногтевой экзостоз является хирургической и ортопедической патологией, заболевание также оказывает негативное влияние на состояние ногтевого аппарата и ногтя в частности. Изменения ногтей при данной патологии отмечаются примерно у 10% пациентов. Поражая аппарат ногтя, подногтевой экзостоз может менять форму и консистенцию (структуру) ногтевой пластины, приводить к развитию различных ониходистрофий, что может значительно повлиять на сроки постановки верного диагноза и дальнейшее ведение пациента. Это обстоятельство также усугубляется часто бессимптомным течением заболевания, при котором патологические изменения ногтей могут быть единственным клиническим признаком поражения костно-хрящевых структур. Поражения ногтей при подногтевом экзостозе могут имитировать другие онихопатии, включая инфекционные поражения, опухоли аппарата ногтя, или быть причиной других ассоциированных расстройств, таких как онихокриптоз. Однако в большинстве случаев изменения ногтей при данной патологии являются неспецифическими, что создает дополнительные трудности для клиницистов в рамках рутинного приема. Следует отметить, что своевременная диагностика и рациональная терапия подногтевого экзостоза имеют важное значение в предупреждении развития таких осложнений, как остеомиелит и образование язв. Это особенно актуально для пациентов с сосудистыми и метаболическими нарушениями. Результаты. В данной статье представлены данные о подногтевом экзостозе и вариантах поражений ногтей при данной патологии. Особое внимание уделено вопросу дифференциальной диагностики между поражениями ногтей при подногтевом экзостозе и другими онихопатиями, включая различные типы ониходистрофий, доброкачественные и злокачественные опухоли аппарата ногтя, другие ассоциированные расстройства. По мнению авторов, подногтевой экзостоз и ассоциированные с ним поражения ногтей являются важной междисциплинарной проблемой, требующей активного участия как ортопедов, так и дерматологов.</p></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Subungual exostosis is an overgrowth of bone and/or cartilage tissue in the area of the distal phalanx of the finger. The etiopathogenesis of the disease remains incompletely understood. It is believed that many exogenous and endogenous factors participate in the development of subungual exostosis. The epidemiology of the disease also remains incompletely understood with conflicting data on its gender and age characteristics. Most often, toes are affected. Despite the fact that subungual exostosis is a surgical and orthopedic pathology, the disease also has a negative impact on the condition of the nail apparatus and the nail in particular. Nail changes with this pathology are observed in approximately 10% of patients. Affecting the nail apparatus, subungual exostosis can change the shape and consistency (structure) of the nail plate, lead to the development of various onychodystrophies, which can significantly affect the timing of the correct diagnosis and further patient management. This circumstance is also aggravated by the often asymptomatic course of the disease, in which nail pathological changes may be the only clinical sign of damage to the bone/chondral structures. Nail lesions in subungual exostosis can imitate other onychopathies, including infectious diseases, nail tumors, or be the cause of other associated disorders, such as onychocryptosis. However, in most cases, nail changes in this pathology are nonspecific, which creates additional difficulties for clinicians in the framework of routine care. It should be noted that timely diagnosis and rational therapy of subungual exostosis are important in preventing the development of complications such as osteomyelitis and ulceration. This is especially important for patients with vascular and metabolic disorders.</p></sec><sec><title>Results</title><p>Results. This article presents data on subungual exostosis and variants of nail lesions in this pathology. Particular attention is paid to the issue of differential diagnostics between nail lesions in subungual exostosis and other onychopathies, including various types of onychodystrophies, benign and malignant nail tumors, and other associated disorders. According to the authors, subungual exostosis and associated nail lesions is an important interdisciplinary problem that requires the active participation of both orthopedists and dermatologists. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>подногтевой экзостоз</kwd><kwd>онихолизис</kwd><kwd>микоз ногтей</kwd><kwd>опухоли ногтевого ложа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>subungual exostosis</kwd><kwd>onycholysis</kwd><kwd>nail mycosis</kwd><kwd>nail bed tumors</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">Mavrogenis A., Papagelopoulos P., Soucacos P.
