The purpose of this study was to evaluate morphologically the tongue of individuals with chronic Chagas disease (CD) in comparison to the non-chagasic ones. Twenty-four protocol cases of autopsies were selected. They were subdivided into CD patients (10 cases) and non-chagasic ones (14 cases). The morphometric analysis was accomplished for the tongue muscle and salivary glands duct lumen area. In three CD patients, perineuritis was found, and two of them showed megaesophagus and megacolon. The intensity of the inflammation in the von Ebner's glands, the tongue muscles, and the salivary glands duct lumen area was significantly higher in the CD patients. We concluded that the CD patients show salivary glands duct dilatation, which probably would have a relation with alterations in the autonomic nervous system. The inflammation found in CD patients is in accordance with that described in comparative studies on the digestive tract and heart. These morphological findings suggest that the histopathological analysis of the tongue associated with other organs, or even in an isolated manner, can add in the diagnosis and pathogenesis of the CD chronic phase.

Although sialoblastoma (SBL) is defined as a low-grade malignant salivary gland anlage neoplasm in the 2022 World Health Organization (WHO) Classification of Head and Neck Tumors, its histology, genetics, and behavior remain controversial due to the rarity of the tumor. Here, we performed the first comprehensive clinical, histologic, and molecular analyses of 8 SBLs to better understand their pathogenesis and prognosis. This cohort consisted of 5 boys and 3 girls, with ages ranging from birth to 9 years at diagnosis.

Non-healing degenerative wounds are thought to be irreparable, in part, by the inability of the tissue to respond to reparative stimuli. As such, treatments are typically aimed at slowing tissue degeneration or replacing cells through transplantation.

Objectives: Head and neck malignancies (HNMs) encompass a variety of cancers that affect the oral and para-oral tissues, the most common of which are squamous cell carcinomas. Radiotherapy is commonly used to treat these cancers, often involving radiation exposure to the salivary glands. This study aims to investigate the early impacts of radiotherapy on the internal microstructure of the salivary gland cells and identify which gland exhibits the highest level of radiosensitivity.

Objective: To assess the effectiveness of labial minor salivary gland biopsy (LSGB) alone or in combination with punch skin biopsy (SB) for the detection of amyloid deposits in hereditary transthyretin amyloidosis with polyneuropathy (ATTRv-PN).
Methods: In this single-center retrospective study, Congo red staining of minimal invasive LSGB (4 mm) and SB (3 mm) was assessed in ATTRv-PN patients consecutively evaluated between 2012 and 2023.
Results: Histopathological data of 171 ATTRv-PN, including 49 early-onset p.

Objectives: To evaluate the characteristics related to oral health and salivary production in patients with Differentiated Thyroid Carcinoma (DTC) after radioiodine therapy (RIT).
Methods: Cross-sectional study, which included patients with DTC after ablative and/or adjuvant RIT. Patients underwent assessment of oral health conditions, subjective assessment of xerostomia and measurement of salivary flow.
