ABSTRACT Background Rhabdomyosarcoma (RMS), a rare malignant tumor, frequently affects pediatric patients, with 35%–40% occurring in the head and neck. This study analyzes clinicopathologic profile of neck rhabdomyosarcomas from Brazil, Guatemala, Mexico, South Africa. Methods We reviewed 44 cases 10 Oral Maxillofacial Pathology services, conducting immunohistochemical analyses desmin, myogenin, Myo‐D1, Ki67, quantification via QuPath software. Cases ≥ 50% myogenin expression were tested for...
Understanding the early molecular events driving oral carcinogenesis is vital for diagnosing squamous cell carcinoma (OSCC) promptly. While metabolic differences between leukoplakia (OLK), OSCC, and healthy mucosa have been reported, changes distinguishing malignant transformed OLKs (MT-OLK) from non-transformed (NT-OLK) remain unexplored. Here, we examine metabolomic profiles of 5 cases MT-OLK 15 NT-OLK to identify key predictive molecules using untargeted high-performance liquid...
There is some evidence of Twist participation in oral carcinogenesis; however, little known about its interaction with E-cadherin squamous cell carcinoma (OSCC) development. This experimental study included an immunohistochemical analysis and proteins paraffin-embedded specimens leukoplakia (OL), OSCC, normal mucosa. In addition, it was also performed a Western blot double-immunofluorescence expression OSCC lines. Significant differences immunoexpression were observed between mucosa OL,...
Abstract: Chat generative pre-trained transformer (ChatGPT), a large language model based on the GPT-3.5 architecture, has potential to revolutionize field of medicine. As machine learning tool, ChatGPT ability analyze vast amounts medical data and provide clinicians with accurate relevant information improve patient care. One key advantages is its assist in evidence-based medicine, as it can datasets clinical trials other studies help identify most effective treatments for specific...
The aim of this study was to investigate the prevalence oral sarcomas from geographic regions Brazil.A cross-sectional conducted on biopsies obtained January 2007 December 2016 at twelve Brazilian and maxillofacial pathology centres. Gender, age, evolution time, clinical aspects, tumour location, size diagnosis, radiographic aspects histopathological diagnosis were evaluated. Data analysed using descriptive statistical methods.From 176,537, a total 200 (0.11%) reported, most prevalent...
Odontogenic tumors (OT) are composed of heterogeneous lesions, which can be benign or malignant, with different behavior and histology. Within this classification, ameloblastoma ameloblastic carcinoma (AC) represent a diagnostic challenge in daily histopathological practice due to their similar characteristics the limitations that incisional biopsies represent. From these premises, we wanted test usefulness models based on artificial intelligence (AI) field oral maxillofacial pathology for...
Abstract Aim Langerhans cell histiocytosis (LCH) is an unusual proliferative disorder of bone marrow‐derived histiocytes (Langerhans cells) that can produce focal or systemic manifestations. Oral manifestations LCH present as single multiple lesions and be a challenge in clinical practice. The aim this paper to the clinicopathological features series nine patients with oral involvement. Methods results patient's age ranged from 2 63 years being five males four females. most common site...
