Lip Granular Cell Tumor (GCT) in a Pediatric Patient: Critical Literature Review on Pediatric Intraoral GCT and Acquired and Congenital Intraoral Non-Neural GCT.

Granular cell tumor (GCT) is an uncommon benign neoplasm derived from Schwann cells, frequently affecting the oral cavity, skin, and gastrointestinal tract. On microscopy, pseudocarcinomatous squamous hyperplasia (PSH) and perineural involvement are potential diagnostic pitfalls. GCT should be differentiated from non-neural GCT (NN-GCT). A 13-year-old male patient was referred presenting a nodular lesion on the upper lip several months ago. After excisional biopsy, microscopy revealed GCT without PSH but presenting multifocal perineural involvement. By immunohistochemistry, ALK was negative, whereas Rb and INI1 expression was intact. Moreover, with few intraoral NN-GCTs being assessed, recent studies suggest that acquired dermal NN-GCT subgroup seems to correspond to ALK-rearranged variants of epithelioid fibrous histiocytoma. Accordingly, further research on this topic is strongly encouraged.

Análise retrospectiva das atividades desenvolvidas pelo grupo PET Odontologia no Vale / Retrospective analysis of activities developed by the PET Dentistrygroup in the Valley

O Programa de Educação Tutorial(PET) visa fortalecer o modelo de indissociabilidade de ensino, pesquisa e extensão,contribuindo para processo de ensino e aprendizagem nas instituições de ensino superior brasileiras. O grupo PET Odontologia no Vale foi fundado em 2009 na Universidade Federal dos Vales do Jequitinhonha e Mucuri(UFVJM). Desde então, o grupo atua no desenvolvimento de atividades que abrangem a integração dialógica, com ações voltadas à formação acadêmica de excelência e às necessidades de saúde da comunidade, considerando a realidade social, cultural e econômica do Vale do Jequitinhonha. O presente artigo teve por objetivo reportar as atividades desenvolvidas pelo grupo PET Odontologia no Vale no período de 2013 a 2020. Foram documentadas 93 atividades, que compreenderam 49 ações de ensino, 35 de extensão e 9 de pesquisa. Destas, 79 foram plenamente desenvolvidas e 14 foram parcialmente desenvolvidas. Referente ao público-alvo, 71 (76,34%) foram destinadas à comunidade acadêmica da UFVJM e 15 ações (16,13%) à comunidade externa. Esses resultados apontam a importância do PET Odontologia no Vale e seus valores no contexto em que o grupo se insere (AU).

The Tutorial Education Program (PET) aims to strengthen the model of inseparable teaching, research, and extension, contributing to the teaching and learning process in the Brazilian higher education institutions. The PET Dentistry in the Valley group was founded in 2009 at the Federal University of the Vales do Jequitinhonha e Mucuri (UFVJM). Since then, the group has been active in the development of activities that cover dialogic integration, with actions aimed at excellent academic training and community health needs, considering the social, cultural, and economic realities of the Jequitinhonha Valley. This article aimed to report the activities developed by the PET Dentistry in the Valley group from 2013 to 2020. Ninety-three activities were documented,comprising 49 teaching actions, 35 extensions, and 9 research. Of these, 79 have been fully developed and 14 have been partially developed. Regarding the target audience, 71 (76.34%) were aimed at the academic community at UFVJM and 15 actions (16.13%) atthe external community. These results show the importance of PET Dentistry in the Valley and its values in the context in which the group is inserted (AU).
