As a rule, Meissner's tactile corpuscles are few in number, but in rare cases they represent the predominant component of the formation tissue.</p> <p><bold><italic>CLINICAL CASE DESCRIPTION: </italic></bold>The authors describe a case of their observation: a 4 y.o. patient with diffuse neurofibroma consisting of structures resembling tactile corpuscles. Clinically, this fibroma looked like a defect in the occipital soft tissue region with excessive folding and alopecia. At the histological examination, the dermis and subcutaneous adipose tissue were seen involved in the pathological process. The formation tissue consisted mostly of "neuroid" structures resembling tactile corpuscles located among fibroblast-like cells with mast cell admixture in the infiltrate. An immunohistochemical examination revealed expression of S100 in them, EMA, GLUT1 in the perineuria, and CD34 in the stroma. Melanocytic marker (MelanA, HMB45) expression was not detected.</p> <p><bold><italic>CONCLUSION</italic></bold><bold><italic>:</italic></bold> The case presented by the authors is of interest to professionals due to the rarity of this morphological variant, difficulties of clinical and histological differential diagnostics with other tumors and tumor-like processes in children.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование</bold><bold>.</bold> Структуры, напоминающие осязательные тельца Мейсснера, были описаны в различных опухолях периферических нервов, включая шванномы и нейрофибромы, а также в составе врождённых меланоцитарных невусов и гамартомы нервного гребешка. Как правило, тельца Мейсснера немногочисленны, однако в редких случаях представляют собой преобладающий компонент ткани образования.</p> <p><bold>Описание клинического случая.</bold> Описан случай наблюдения пациента 4 лет с диффузной нейрофибромой, состоящей из структур, напоминающих осязательные тельца. Клинически нейрофиброма представляла собой дефект мягких тканей затылочной области в виде избыточной складчатости в сочетании с алопецией. При гистологическом исследовании было выявлено вовлечение в патологический процесс дермы и подкожной жировой ткани. Ткань образования состояла преимущественно из «невроидных» структур, напоминающих осязательные тельца, расположенные среди фибробластоподобных клеток с примесью тучных клеток в инфильтрате. При иммуногистохимическом исследовании в них была выявлена экспрессия белков S100, в периневрии — эпителиального мембранного антигена, однонаправленного белка-переносчика глюкозы, в строме — антигена CD34. Экспрессии меланоцитарных маркеров (MelanA, HMB45) выявлено не было.</p> <p><bold>Заключение.</bold> Данный случай представляет интерес ввиду редкости данного морфологического варианта, трудностям клинической и гистологической дифференциальной диагностики с другими опухолями и опухолеподобными процессами детского возраста.</p></trans-abstract><kwd-group xml:lang="en"><kwd>pediatric surgery</kwd><kwd>dermatology</kwd><kwd>plastic surgery</kwd><kwd>case reports</kwd><kwd>diffuse neurofibroma</kwd><kwd>meissnerian neurofibroma</kwd><kwd>tactile corpuscles</kwd><kwd>tumors</kwd><kwd>endoexpander</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>детская хирургия</kwd><kwd>дерматология</kwd><kwd>пластическая хирургия</kwd><kwd>клинический случай</kwd><kwd>диффузная нейрофиброма</kwd><kwd>мейсснерова нейрофиброма</kwd><kwd>осязательные тельца</kwd><kwd>опухоли</kwd><kwd>эндоэкспандер</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">Elder D, Massi D, Scolyer R, Willemze R.
