Objectives: The aim of this study was to investigate the prevalence of oral sarcomas from geographic regions of Brazil.
Materials And Methods: A cross-sectional study was conducted on biopsies obtained from January 2007 to December 2016 at twelve Brazilian oral and maxillofacial pathology centres. Gender, age, evolution time, clinical aspects, tumour location, tumour size at diagnosis, radiographic aspects and histopathological diagnosis were evaluated. Data were analysed using descriptive statistical methods.
Results: From 176,537, a total of 200 (0.11%) oral sarcomas were reported, and the most prevalent were osteosarcomas (74 cases; 37%) and Kaposi's sarcomas (52 cases; 26%). Males were more affected than females at a mean age of 32.2 years old (range of 3-87 years). The most common symptoms were swelling¸ localised pain and bleeding at a mean evolution time of 5.14 months (range <1-156 months). The lesions were mostly observed in the mandible (90 cases; 45%), with a mean tumour size of 3.4 cm (range of 0.3-15 cm). Radiographically, the lesions presented a radiolucent aspect showing cortical bone destruction and ill-defined limits.
Conclusions: Oral sarcomas are rare lesions with more than 50 described subtypes. Osteosarcomas and Kaposi's sarcomas were the main sarcomas of the oral cavity in Brazil.

Background: Oral squamous cell carcinoma (OSCC) is one of the most prevalent oral cancers in the world. The major etiological factors are considered to be tobacco and alcohol. However, the etiological factors for non-habit associated oral squamous cell carcinoma (NHOSCC) remains an enigma.

Odontogenic neoplasms of the jaw are dominated by ameloblastoma (AM), a locally aggressive epithelial tumor with a significant propensity for recurrence. The World Health Organization's 2022 update to the AMclassification system underscores recent progress in comprehending its underlying mechanisms and refining clinical approaches. Contemporary research has yielded significant insights into the genetic underpinnings of AM, paving the way for the development of precision-based treatment strategies.

Objective: The aim of this study was to provide a comprehensive clinicopathological analysis of oral Kaposi sarcoma (KS) cases and examine its relationship with HIV-related immunosuppression.
Study Design: Paraffin-embedded tissue blocks of patients microscopically diagnosed with oral KS were retrieved from three oral and maxillofacial pathology files. Data including clinical, laboratory, microscopic and immunohistochemical findings and treatment employed were retrieved.

Small cell osteosarcoma (SCOS) is a rare variant of conventional osteosarcoma, characterized by tumor cells of small size and uniform morphology, which can lead to diagnostic confusion with other small cell tumors, requiring a detailed diagnostic approach. The manifestation in a child adds a degree of complexity, as the management of malignant tumours in paediatric patients requires specific considerations to minimize the long-term side effects of oncological treatment and preserve the structural and functional development of the orofacial region. This report concerns an 8-year-old female patient referred to the Oral and Maxillofacial Surgery outpatient clinic with progressive swelling in the right maxillofacial region, initially asymptomatic, but progressing to pain and difficulty chewing.

Objective: Survivors of pediatric head and neck rhabdomyosarcoma (HNRMS) are at risk of developing endocrinopathies following local treatment, resulting from radiation damage to the pituitary gland, hypothalamus, or thyroid gland, often at a young age. Our aim was to determine the prevalence of endocrine dysfunction in long-term HNRMS survivors and compare the prevalence of anterior pituitary insufficiency (API) among different local treatment strategies: external beam radiation with photons, external beam radiation with protons, microscopically radical surgery combined with external irradiation, and macroscopic radical surgery combined with brachytherapy.
Design And Methods: Head and neck rhabdomyosarcoma survivors treated between 1993 and 2017, with ≥2 years of follow-up, without recurrent disease or secondary malignancy were eligible for this study.
