We report a 7-year-old boy who presented with a nodule on the upper lip. A previous clinical history of mechanical trauma in the lesional area had been noted. After surgical excision, microscopy revealed fibrocollagenous fascicles associated with neurovascular bundles and skeletal striated muscle fibers in diffuse subepithelial distribution, suggesting rhabdomyomatous mesenchymal hamartoma. However, strict clinicopathological correlation favored a healing process with trapped striated skeletal muscle tissue. After three years of follow-up, an improvement in the aesthetic appearance of the upper lip was observed. To the best of our knowledge, a case of pseudo-rhabdomyomatous mesenchymal hamartoma has not been reported to date.

Background: Necrotizing sialometaplasia (NSM) is a rare self-limiting inflammatory lesion, with most cases affecting the minor salivary glands, especially those located in the palate (70%). To date, about 261 cases of NSM have been reported. Of them, 7 cases affected the tongue; 37 cases occurred after surgery; and 17 cases showed association with neoplasms. Methods: A 50-year-old male patient was diagnosed with squamous cell carcinoma (SCC) of the tongue. After surgical excision, the tumor diagnosis was well-differentiated SCC with a close surgical margin. Re-excision of the margin was indicated. Results: Microscopically, the surgical margin showed neither residual SCC nor epithelial dysplasia. However, it was possible to observe 7 foci containing typical areas of NSM distributed throughout the surgical specimen, which, by immunohistochemistry, revealed a glandular nature with presence of myoepithelial cells. Conclusion: We present here an unusual multifocal NSM affecting the tongue at the site of a prior resection for SCC with close margins, which, to the best of our knowledge, has not been reported to date.

Purpose: Approximately 10% of all lymphomatoid papulosis (LyP) cases affect pediatric patients. Pediatric LyP is clinically similar to adult LyP, frequently with cutaneous involvement, whereas the affectation of mucosal surface is rare. The LyP clinicopathological spectrum includes type A, B, C, D, E, and LyP with DUSP22/IRF4 rearrangement, with LyP type D representing < 5% of all LyP cases. Methods: We have previously reported 2 cases of exclusively intraoral LyP type C and E. To date, about 50 cases of LyP type D have been reported; of them, 8 cases, all but one with exclusive skin involvement, corresponded to pediatric patients. Rare LyP type C cases can lack CD30 expression, creating diagnostic difficulties with lymphoma. Results: Here, we report an extremely rare case of intraoral LyP type D with scarce/absent CD30 expression affecting a 12-year-old white Brazilian boy. Conclusions: To our best knowledge, this is the first pediatric case of LyP type D with exclusive intraoral involvement. [ABSTRACT FROM AUTHOR]

This study investigates the impact of conventional versus non-conventional materials on creativity and perceived workload in architectural model-making. Motivated by the need to foster creativity in architectural education, the research hypothesized that unfamiliar materials could stimulate novel design solutions while potentially increasing cognitive and emotional demands. The study was conducted in two phases: defining conventional and non-conventional materials through a survey of architecture professionals and students and a controlled experiment where participants used these materials to create scale models. Creativity was evaluated using Shah's novelty metric, and workload was measured using the NASA-TLX questionnaire. Results show that models made with non-conventional materials exhibited higher novelty, supporting the hypothesis that unfamiliar materials encourage creative exploration. Surprisingly, perceived workload was lower for non-conventional materials, suggesting that the open-ended nature of the task promoted engagement and alleviated cognitive strain. These findings highlight the potential of non-conventional materials to enhance creativity in architectural education while reducing workload stress, though variability in performance suggests the need for adaptive teaching strategies to support students. Future research should explore how materiality impacts creativity over time in more realistic settings. Additionally, other disciplines supported by physical models during the design process could benefit from similar studies. [ABSTRACT FROM AUTHOR]
