Oral leukoplakia, leukoerythroplakia, erythroplakia and actinic cheilitis: Analysis of 953 patients focusing on oral epithelial dysplasia.

Background: To analyse the clinical and histological characteristics from a series of oral leukoplakias, leukoerythroplakias, erythroplakias and actinic cheilitis diagnosed in a 14-year period.

Methods: The files were reviewed and all cases diagnosed as leukoplakia, leukoerythroplakia, erythroplakia and actinic cheilitis were selected. Clinical information was obtained from the biopsy submission forms, and histological review was performed in all cases.

Oral and oropharyngeal diffuse large B-cell lymphoma and high-grade B-cell lymphoma: A clinicopathologic and prognostic study of 69 cases.

Objective: The objective of this study was to describe the clinicopathological, molecular, and prognostic features of oral/oropharyngeal diffuse large B-cell lymphoma (DLBCL) and high-grade B-cell lymphoma.

Study Design: All cases were retrieved from 7 Brazilian institutions. Immunohistochemical reactions were performed to confirm the diagnoses and to categorize the tumors.

Clinical and radiological analysis of a series of periapical cysts and periapical granulomas diagnosed in a Brazilian population.

Background: Periapical cysts (PC) and periapical granulomas (PG) are the two most common chronic inflammatory periapical diseases, but their clinicoradiological characteristics can vary depending on the methods employed in each study. The aim of the present work was to analyze the clinical and radiological profile of a series of PC and PG diagnosed in a Brazilian population.

Material And Methods: The files of two Oral Pathology laboratories were reviewed and all cases diagnosed as PG and PC were selected for the study.

Clinical and laboratorial profile and histological features on minor salivary glands from patients under investigation for Sjögren's syndrome.

Unlabelled: Diagnosis of Sjögren's syndrome (SS) is complex and the usefulness of labial minor salivary glands biopsy in this process remains controversial.

Objective: to evaluate the clinical and laboratorial profile and histological features on labial minor salivary glands from patients under investigation of SS.

Study Design: clinical charts from 38 patients under suspicion of SS and submitted to labial minor salivary glands biopsies were reviewed.

Histopathological features of keratocystic odontogenic tumor: a descriptive study of 177 cases from a Brazilian population.

The aim of this study was to describe the clinicopathologic features of 177 keratocystic odontogenic tumors (KCOTs) diagnosed in a Brazilian population. A total of 177 KCOTs were reviewed and affected 158 patients with ages ranging from 5 to 79 years (mean age = 32 years) with a slight female predominance. Mandible was the most common affected site (69.

Comparative clinicopathological study of intraoral sebaceous hyperplasia and sebaceous adenoma.

Objective: The objective of this study was to compare the clinicopathological features of oral sebaceous hyperplasia and sebaceous adenoma.

Study Design: Clinical data, microscopical characteristics, and ki-67 immunoexpression were comparatively analyzed on 2 intraoral sebaceous adenomas, 6 intraoral sebaceous hyperplasias, and 21 normal intraoral sebaceous glands.

Results: Clinically, sebaceous glands presented as multiple separated papules, sebaceous hyperplasias as a single enlarged papule, and sebaceous adenoma as a well-defined nodule.

Fine-needle aspiration biopsy as an auxiliary diagnostic tool on intraoral minor salivary gland adenoid cystic carcinoma.

Background: Fine-needle aspiration biopsy (FNAB) is useful in diagnosis of major salivary gland adenoid cystic carcinoma (ACC), but it has been rarely reported on minor salivary gland ACC.

Objective: The aim of this study was to report the utility of FNAB on diagnosis of ACC involving minor salivary glands.

Study Design: Three patients presenting ACC involving the palate (2 cases) and buccal mucosa (1 case), with a mean age of 36 years and 2:1 female-to-male ratio, were included in the study.
