Oral leiomyomatous hamartoma (OLH) is a rare lesion, with only 40 cases reported in the literature. It typically presents early in life as a nodule on the anterior maxillary alveolar tissues or the tongue. Its growth potential is limited, with few cases reaching dimensions >2.0 cm, and its microscopic composition includes an intact surface mucosa with an underlying fibrovascular stroma possessing an unencapsulated proliferation of smooth muscle fascicles. Excision is considered the definitive treatment. Here we describe the clinical, microscopic, histochemical, and immunohistochemical features and management of 3 cases of OLH and review the literature...

OBJECTIVE: Sirolimus (SRL) and everolimus (EVL) are increasingly included in immunosuppressive protocols after heart transplantation. They present some side effects, including the appearance of painful lesions in the oral cavity. Therefore, this systematic review aimed to verify the global prevalence and clinical characteristics of oral lesions induced by SRL and EVL in heart transplant patients. STUDY DESIGN: A systematic review was performed using 5 main electronic databases (Medline/PubMed, SCOPUS, EMBASE, Web of Science, and LILACS), in addition to the gray literature...

OBJECTIVE: We aimed to describe and analyze the epidemiologic and clinical variables associated with, treatment for, and development of cervicofacial infection (CFI). STUDY DESIGN: We retrospectively examined 201 patients older than 14 years who had met the CFI diagnostic criteria and whose treatment required hospitalization and intervention under general anesthesia at our hospital. We performed chi-square tests to compare proportions in categorical variables and either the Student t test or the Wilcoxon signed-rank test to compare quantitative variables...

OBJECTIVE: This study analyzed the systemic and oral abnormalities in individuals with Kabuki syndrome (KS) that might be investigated to enhance the early diagnosis and treatment by a multidisciplinary team, minimizing the consequences to the individual's health. STUDY DESIGN: Clinical examination was conducted on 15 individuals to investigate orodental alterations such as tooth abnormalities and cleft lip and/or palate, and the patient records were also reviewed to investigate systemic diseases such as cardiopathies, infectious and immunologic diseases, nephropathies, and delayed neuropsychomotor development...

OBJECTIVES: This study aimed to develop machine learning models to predict phosphorylated mesenchymal-epithelial transition factor (p-MET) expression in oral tongue squamous cell carcinoma (OTSCC) using magnetic resonance imaging (MRI)-derived texture features and clinical features. METHODS: Thirty-four patients with OTSCC were retrospectively collected. Texture features were derived from preoperative MR images, including T2WI, apparent diffusion coefficient mapping, and contrast-enhanced (ce)-T1WI...

OBJECTIVE: The aim was to optimize diagnostics for carotid artery calcifications (CACs) on panoramic radiographs (PRs) to identify cardiovascular disease (CVD) by investigating how 4 defined CAC shapes are associated with ultrasound (US) findings indicating CVD. STUDY DESIGN: The study included 414 participants (802 neck sides) from the Malmö Offspring Dental Study, examined with PRs. The PRs were assessed for CAC shapes stratified into 4 categories: single, scattered, vessel-width defining, and vessel-outlining...

The occurrence of clear cell histologic sub-type of oral squamous cell carcinoma in the oral cavity is a distinct and exceedingly rare entity exhibiting aggressive behavior. To date, only 10 cases have been published in the literature. We describe 2 extremely rare cases, both presenting with swelling and ulcerated nodule-like proliferative growth in the mandible. Microscopically, sheets and lobules of neoplastic squamous epithelial cells showing clear cell differentiation were appreciated in both patients. Periodic acid-Schiff and mucicarmine revealed negative staining...
