Automated Scoring of Nuclear Pleomorphism Spectrum with Pathologist-level Performance in Breast Cancer [PDF]

open access: yesarXiv, 2020
Nuclear pleomorphism, defined herein as the extent of abnormalities in the overall appearance of tumor nuclei, is one of the components of the three-tiered breast cancer grading. Given that nuclear pleomorphism reflects a continuous spectrum of variation, we trained a deep neural network on a large variety of tumor regions from the collective knowledge

Pleomorphic structural imperfections caused by pulsed Bi-implantation in the bulk and thin-film morphologies of TiO2 [PDF]

open access: yes, 2016
The results of combined experimental and theoretical study of substitutional and clustering effects in Bi-doped TiO2 hosts (bulk and thin-film morphologies) are presented. Bi-doping of the bulk and thin-film titanium dioxide was made with help of pulsed ion-implantation (E(Bi+) = 30 keV, D = 1 * 1017 cm-2) without posterior tempering.

Radiotherapy for pleomorphic adenoma

open access: yesAmerican Journal of Otolaryngology, 2013
The aim of this study was to update our experience in treating pleomorphic adenoma with radiotherapy (RT).This is a retrospective analysis of 25 patients treated with RT alone (2 patients) or combined with surgery (23 patients), with follow-up ranging from 1.8 to 34.9 years (median, 10.5 years).Local control was achieved in 13 (75%) of 16 patients with

An unusual pleomorphic adenoma [PDF]

open access: yesRGO - Revista Gaúcha de Odontologia, 2014
Pleomorphic adenoma is the most common neoplasm in major and minor salivary glands. It constitutes approximately 90% of all benign salivary gland lesions and the parotid is the most affected location. When the minor salivary glands are affected, it mostly occurs at the junction of the hard and soft palates. The diagnosis is complex because of the great

Pleomorphic adenoma of buccal minor salivary gland: A case report

open access: yesJournal of Craniomaxillofacial Research, 2023
Pleomorphic adenoma is a benign salivary gland tumor that is frequently seen in the parotid gland. It is very rare in minor salivary glands. The case we present is a case of pleomorphic adenoma originating from the buccal minor salivary gland, which ...

Learning Interpretable Microscopic Features of Tumor by Multi-task Adversarial CNNs To Improve Generalization [PDF]

open access: yes, 2020
Adopting Convolutional Neural Networks (CNNs) in the daily routine of primary diagnosis requires not only near-perfect precision, but also a sufficient degree of generalization to data acquisition shifts and transparency. Existing CNN models act as black boxes, not ensuring to the physicians that important diagnostic features are used by the model ...

Immunohistochemical Expression of p53 in Pleomorphic Adenoma and Carcinoma Ex Pleomorphic Adenoma [PDF]

open access: yesJournal of Cancer Epidemiology, 2010
Context. Immunohistochemical stains for p53 are used as a diagnostic marker associated with malignancy in several histologic types of salivary gland tumors. This marker may be useful in differentiating pleomorphic adenoma (PA) from carcinoma ex pleomorphic adenoma (CPA), as these tumors are often difficult to distinguish on the basis of morphology ...

Insight Into Body Size Evolution in Aves: Based on Some Body Size–Related Genes

open access: yesIntegrative Zoology, EarlyView.
These findings provide new insights into the genetic determinants of body size evolutionary mechanisms in Aves. ABSTRACT Birds exhibit remarkable variations in body size, making them an ideal group for the study of adaptive evolution. However, the genetic mechanisms underlying body size evolution in avian species remain inadequately understood.

A case of lipomatous pleomorphic adenoma in the parotid gland: a case report

open access: yesDiagnostic Pathology, 2009
Introduction Pleomorphic adenoma is the most common benign neoplasm of the salivary glands. Extensive lipomatous involvement of the tumor is, however, a very rare finding.

Pleomorphic adenoma of the cheek: a case presentation

open access: yesThe Egyptian Journal of Otolaryngology, 2022
Background Pleomorphic adenoma, also known as a benign mixed tumor, is the most common salivary gland tumor. The parotid gland accounts for 90% of the total, with the minor salivary glands accounting for 10%.
