Epithelioid rhabdomyosarcoma: Report of the first case in the jaw.

Objectives: Epithelioid rhabdomyosarcoma (EpiRMS) is a novel morphologically distinct variant of rhabdomyosarcoma, with an unusually challenging microscopic diagnosis. The occurrence of rhabdomyosarcomas in the jaws is extremely rare. This study presents the first case of EpiRMS in the jaw (mandible) and a literature review of the previous 35 cases of EpiRMS.

Adenoid ameloblastoma in the posterior maxilla: a case report and review of the literature.

Introduction: Adenoid ameloblastoma is a rare benign odontogenic tumor that favors a slight predilection for male patients, fourth and fifth decades of life, and posterior regions of the jaws. To date, less than 40 cases have been reported in the English language literature. The radiographic aspects of adenoid ameloblastoma vary from unilocular and well-defined lesions to diffuse and multilocular lesions.

Bioactive glass containing 90% SiO in hard tissue engineering: An in vitro and in vivo characterization study.

Bioactive glass has been proved to have many applications in bioengineering due to its bone regenerative properties. In this work, an innovative, highly resorbable bioactive glass containing 90% SiO (BG90) to be used as a bone substitute was developed. The BG90 was synthetized by the sol-gel process with the dry step at room temperature.

Calcifying odontogenic cyst, dentinogenic ghost cell tumor, and ghost cell odontogenic carcinoma: A systematic review.

Background: The aim of this study was to integrate the available data published on calcifying odontogenic cyst (COC), dentinogenic ghost cell tumor (DGCT), and ghost cell odontogenic carcinomas (GCOCs) into a comprehensive analysis of their clinicoradiological features, treatment, and recurrence.

Materials And Methods: An electronic search with no publication date restriction was undertaken in October 2017 in the following databases: PubMed, Medline Ovid, Web of Science, and Scopus. Eligibility criteria included publications containing enough clinical, radiological, and histopathological information to confirm a definite diagnosis of these lesions.

Gingival varices treated with monoethanolamine oleate: A rare case report.

Varices are benign blood vessel lesions that are common in the head and neck regions. The aim of this case report is to highlight an uncommon case of gingival varices and its diagnosis and management. This is the second time that a case of varices has been reported at this site.

Prevalence profile of odontogenic cysts and tumors on Brazilian sample after the reclassification of odontogenic keratocyst.

Purpose: The aim of this study was to evaluate the impact of the reclassification of odontogenic keratocyst (OKC) as a tumor on the prevalence profile of odontogenic cysts (OCs) and odontogenic tumors (OTs).

Study Design: Two referral Oral and Maxillofacial Pathology services in Brazil were evaluated. All cases diagnosed as OCs or OTs were selected and classified according to the 1992 WHO-classification (cases before 2005 WHO classification of tumors excluding OKC) and the 2005 WHO classification of tumors, going forward including cases of odontogenic keratocyst tumor (KCOT).
