Oral histiocytic sarcoma: A case report and literature review.

Histiocytic sarcoma (HS) is a rare and aggressive malignancy derived from mature histiocytes, accounting for less than 1% of hematologic disorders. Clinically, HS varies from localized disease with a solitary mass to disseminated disease, often associated with other hematolymphoid neoplasms. Its aggressive nature results in poor outcomes, with a median survival of six months in disseminated cases.

Efficacy of 660 nm Photobiomodulation in Burning Mouth Syndrome Management: A Single-Blind Quasi-Experimental Controlled Clinical Trial.

Burning mouth syndrome (BMS) is characterized by a burning sensation of the oral mucosa without any evidence of clinical signs or underlining condition. Several treatment modalities have been utilized with various results and levels of evidence. Lately, photobiomodulation (PBM) has emerged as a noninvasive effective therapy due to its anti-inflammatory and biostimulatory effects, especially the low-power laser setting of red wavelength.

Voltage-gated sodium channels gene expression in Burning Mouth Syndrome: a case-control study.

Preparation, Antimicrobial Properties, and Cytotoxicity of Acrylic Resins Containing Poly(diallyldimethylammonium chloride).

Purpose: To design and analyze the biologic properties (antibacterial and antifungal, as well as cytotoxicity) of a dental biomaterial based on incorporation of the biocide poly(diallyldimethylammonium chloride) (PDADMAC) into the masses of self- and thermopolymerizable acrylic resins.

Materials And Methods: PDADMAC was diluted into tetrahydrofuran (4 wt%) and incorporated into self- and thermopolymerizable acrylic resins. PDADMAC inclusion was verified by measuring the contact angle with water droplets.

A distinct fibro-osseous lesion of the jaws affecting the maxilla.

The differential diagnosis of fibro-osseous lesions (FOL) presents oral clinician stomatologists with a challenging task because of their similar clinical, radiographic and histopathological behavior that will also hinder the therapeutic planning. Presentation of case to describe the clinical, radiographic and histopathological features of an unusual case of FOL presented by the patient, a Black woman, and the results obtained with the conservative surgical treatment and 3-month follow-up. The presence of cementum in the histopathological analysis of cemento-osseous dysplasias, according to the current literature, is an important factor for the diagnosis of this lesion.

[Not Available].

Introduction: Acrylic resins are used in the preparation of facial prostheses and may be colonized by fungi. Here, we verified the antifungal efficacy of this material after surface treatment using poly (diallyldimethylammonium chloride).

Methods: Acrylic resin specimens with and without surface treatment were subjected to tests for fungistatic and fungicidal activities.

Importance of rapid management in painful progressive ulcerative lesions in elderly immunosuppressed patients: Two case reports.

Oral manifestations of tuberculosis (TB) are not so frequent, and the lesions may emerge in immunosuppressed patients as a secondary expression of pulmonary TB. The following two case reports focus on the clinical challenge of early diagnosis of painful ulcerative lesions in oral mucosa that occurred in two senior females, both human immunodeficiency virus negative patients, however receiving immunosuppressing medication. The patients did not present classic symptoms of TB.

Fatal case of oral metastatic hepatocellular carcinoma in a patient unaware of his disease.

Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer. Metastases to the soft tissues of the oral cavity are extremely uncommon. This report describes a rare case of an oral metastatic HCC, located completely within the oral mucosa overlying the alveolar ridge, in a patient who was unware of his primary disease.

Rosai-Dorfman disease affecting the maxilla.

Rosai-Dorfman disease (RDD), formerly called sinus histiocytosis with massive lymphadenopathy, is a non-neoplastic proliferative histiocytic disorder with behavior ranging from highly aggressive to spontaneous remission. Although the lymph nodes are more commonly involved, any organ can be affected. This study aimed to describe the features and the follow-up of a case of extranodal RDD.

Low Intensity laser therapy in patients with burning mouth syndrome: a randomized, placebo-controlled study.

The aim of this study was to assess the effectiveness of low intensity laser therapy in patients with Burning Mouth Syndrome (BMS). Thirty BMS subjects were randomized into two groups - Laser (LG) and Placebo (CG). Seven patients dropped out, leaving 13 patients in LG and 10 patients in CG.

Evaluation of fine needle aspiration biopsy in oral cavity and head and neck region with different stains techniques.

The present study aimed to evaluate the Fine Needle Aspiration Biopsy in different staining techniques in nodular lesions of the oral cavity and head and neck region, as their sensitivity, specificity and accuracy, staining with Panoptic, Papanicolaou and Hematoxylin-Eosin (H&E) stains. 46 patients who sought the Clinic of the Discipline of Clinical Stomatology at FOUSP were selected consecutively, with nodular lesions in the oral cavity and head and neck region. The material obtained by FNAB was sent on 6 different slides, stained by the method of Panoptic, Papanicolaou and H&E, to the same pathologist only with the clinical diagnosis.

Fibronectin as an adjuvant in the diagnosis of oral inflammatory myofibroblastic tumor.

Inflammatory myofibroblastic tumor is a distinctive lesion composed of myofibroblastic spindle shaped cells accompanied by inflammatory infiltrate that may arise in various organs. It is believed to be a noneoplastic inflammatory condition, although this is still controversial. The recognition of inflammatory myofibroblastic tumor as an entity is important especially to avoid unnecessary surgery.
