Remoção cirúrgica de adenoma pleomórfico e uso de placa palatina

O adenoma pleomórfico é a neoplasia, que apresenta maior procedência das glândulas salivares maiores e menores. Clinicamente apresenta-se como lesão solitária, indolor, bem delimitada e de crescimento lento, não se fixando ao tecido adjacente. O tratamento de eleição consiste na excisão cirúrg...

Comparison of microRNA profiles between benign and malignant salivary gland tumors in tissue, blood and saliva samples: a prospective, case-control study

Abstract Introduction: Salivary gland tumors (SGTs) are rare head and neck malignancies consisting of a spectrum of tumors with different biological behaviors. Objective: In this study we aimed to find out differential expression of microRNA profiles between benign and malignant SGTs. Methods: We inve...

Palatal Pleomorphic Adenoma in a Pediatric Patient: Case Report

Pleomorphic adenoma is the most common benign neoplasm of salivary glands. Their common location is in parotid gland, however, a lower percentage of these tumors might occur in minor glands.

DNA Aneuploidy in Malignant Salivary Gland Neoplasms is Independent of USP44 Protein Expression

Braz. dent. j; 28 (2), 2017
Chromosomal instability, leading to aneuploidy, is one of the hallmarks of human cancers. USP44 (ubiquitin specific peptidase 44) is an important molecule that plays a regulatory role in the mitotic checkpoint and USP44 loss causes chromosome mis-segregation, aneuploidy and tumorigenesis in vivo. In this...

BRD4 inhibition suppresses cell growth, migration and invasion of salivary adenoid cystic carcinoma

Biol. Res; 50 (), 2017
BACKGROUND: Bromodomain-containing protein 4 (BRD4) inhibition is a new therapeutic strategy for many malignancies. In this study, we aimed to explore the effect of BRD4 inhibition by JQ1 on in vitro cell growth, migration and invasion of salivary adenoid cystic carcinoma (SACC). METHODS: The human norma...
