Utility of Proliferation Markers Ki‐67 and PHH3 in Predicting Malignancy in Basaloid Salivary Gland Neoplasms: A Study Using Digital Image Analysis of Cytology Cell Blocks

Diagnostic Cytopathology, Volume 53, Issue 5, Page 238-245, May 2025.
ABSTRACT Introduction Basaloid salivary gland neoplasms (BSNs) are notoriously difficult to classify in fine needle aspiration (FNA) specimens due to the morphologic overlap of benign and malignant entities. Adenoid cystic carcinoma (AdCC) represents a particular diagnostic challenge, as it typically shows low‐grade cytologic features despite its ...

Deep-Learning for Classification of Colorectal Polyps on Whole-Slide Images [PDF]

arXiv, 2017
Histopathological characterization of colorectal polyps is an important principle for determining the risk of colorectal cancer and future rates of surveillance for patients. This characterization is time-intensive, requires years of specialized training, and suffers from significant inter-observer and intra-observer variability. In this work, we built

Synchronous unilateral parotid neoplasms. : a case report [PDF]

, 2009
The parotid gland is the most usual location of benign neoplasms affecting major salivary glands and quite often the recurrence of these tumours is noticed, specially in the case of pleomorphic adenoma. The occurrence of multiple tumours in the parotid

Diagnostic interobserver variability of atypia assessment in columnar cell lesions among a group of expert breast pathologists in the United Kingdom and the Republic of Ireland, on behalf of the UK national coordinating committee for breast pathology

Histopathology, Volume 86, Issue 6, Page 953-966, May 2025.
Interobserver agreement for the presence of atypia in columnar cell lesions is poor, even among breast pathology experts. This can be improved through consensus meetings, but a subset of cases defy classification, because the current definition of flat epithelial atypia does not encompass the range of cytological and architectural atypia observed in ...

Etiology and familial inheritance of pleomorphic adenomas

Dentistry 3000, 2017
Background: A pleomorphic adenoma is the most common salivary gland neoplasm in both children and adults. Pleomorphic adenomas are derived from ductal and myoepithelial cells and are most commonly found in the superficial lobe of the parotid gland.

TP53 and p16INK4A, but not H-KI-Ras, are involved in tumorigenesis and progression of pleomorphic adenomas. [PDF]

, 2006
The putative role of TP53 and p16INK4A tumor suppressor genes and Ras oncogenes in the development and progression of salivary gland neoplasias was studied in 28 cases of pleomorphic adenomas (PA), 4 cases of cystic adenocarcinomas, and 1 case of ...

Orofacial Epidermoid Cysts: A Case Series

Clinical Case Reports, Volume 13, Issue 4, April 2025.
ABSTRACT Epidermoid cysts can occur anywhere in the body but are uncommon in the orofacial region, with a 7% incidence in the head and neck and 1.6% in the oral cavity. We diagnosed two cases in the left cheek and successfully operated on them through an intraoral approach.

Intranasal Pleomorphic Adenoma

An International Journal of Otorhinolaryngology Clinics, 2013
ABSTRACTPleomorphic adenoma is a benign tumor arising from major salivary glands and also has been reported in salivary glands of palate rarely in nasopharynx, oropharynx and larynx and lacrimal glands. We report a case pleomorphic adenoma of nasal septum and discuss the clinical features, management along with review of literature.
