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.

Intraoral EBV-positive sporadic Burkitt lymphoma in an elderly patient with bilateral presentation.

Sporadic Burkitt lymphoma (SBL) is a variant of Burkitt lymphoma that occurs worldwide, affecting mainly children and young adults. Association with Epstein-Barr virus (EBV) can be identified in approximately 20-30% of cases. Herein we described a case of a 63-year-old male presenting intraoral bilateral mandibular swelling, subjacent to fixed dental prosthesis, with one month of duration.

Clinicopathological analysis of oral diffuse large B-cell lymphoma, NOS: A systematic review.

Background: Diffuse large B-cell lymphoma, NOS (DLBCL NOS) is the commonest extranodal non-Hodgkin lymphoma diagnosed in the oral and maxillofacial region. However, few studies are currently available and its prognostic determinants remain undefined.

Purpose: To analyse the available data on oral DLBCL NOS and to describe its clinicopathological features, identifying potential prognostic factors.

Calf's sex, parity and the hour of harvest after calving affect colostrum quality of dairy cows grazing under high tropical conditions.

High-quality colostrum is an important factor influencing neonatal calf health, and quality assessment is essential to obtain good health results. This research evaluated the effects of the calf's sex, the parity of the cow and the hour of colostrum harvest after parity on the fat, nonfat solids, protein and Ig contents in Holstein colostrum for cows under high grazing conditions in the tropics. The effects of the calf's sex and parity on somatic cell count (SCC) at the first milking postpartum were determined.
