Morphological Characteristics of Various Cells in Esophageal Squamous Dysplasia: Extremely Wide Morphological Spectrum.

The WHO classification of esophageal tumors divides esophageal squamous intraepithelial dysplasia into high and low grades, but does not specify its morphological spectrum. Here, the morphological characteristics of various cells were investigated in esophageal squamous (high-grade) dysplasia, and a morphological spectrum and terminology for this lesion were proposed to avoid misdiagnosis. The clinicopathological data of 540 patients with esophageal squamous dysplasia were analyzed retrospectively.

[Clinicopathological features of verrucous type dysplasia of esophagus].

To investigate the clinicopathological features of verrucous type (squamous) dysplasia of esophagus. The clinicopathological data of 18 verrucous type dysplasia of esophagus patients in the 989th Hospital of the Joint Logistics Support Force of the People's Liberation Army (formerly 152 Central Hospital) and Beijing Chaoyang Hospital Affiliated to Capital Medical University from 2009 to 2021 were retrospectively collected. The histomorphologic characteristics and immunophenotype were observed, and human papillomavirus (HPV) genotyping was detected by PCR-fluorescence probe.

[Clinicopathological features of very well-differentiated adenocarcinoma of the stomach].

To investigate the clinicopathological features of very well-differentiated adenocarcinoma (VWDA) of the stomach. The clinicopathological data of 12 cases of VWDA of the stomach were collected retrospectively at the People's Liberation Army Joint Logistics Support Force 989 Hospital (formerly 152 Hospital), Pingdingshan, China, from January 2013 to May 2021. The histological characteristics and immunophenotypes were observed and analyzed with review of current literature.

[Clinicopathological features of differentiated-type dysplasia of the esophagus].

To investigate the clinicopathological features of differentiated-type (squamous) dysplasia of the esophagus. A total of 184 cases of esophageal differentiated-type dysplasia were collected retrospectively at People's Liberation Army Joint Logistics Support Force 989 Hospital (formerly 152 Hospital), and Beijing Chaoyang Hospital, Capital Medical University, China from 2016 to 2019. Their histological characteristics and immunophenotypes were analyzed, and related literature was reviewed.

[Spindle cell type squamous dysplasia of the esophagus: a clinicopathological analysis].

To investigate the clinicopathological features and significance of spindle cell type squamous dysplasia of the esophagus. The clinicopathological data of 37 cases of spindle cell type squamous dysplasia of esophagus were collected retrospectively at People's Liberation Army Joint Logistics Support Force 989 Hospital (formerly 152 Hospital), Pingdingshan, China, from 2009 to 2019. The histological and immunohistochemical characteristics were analyzed, with a literature review.

[Role of Claudin-1 on diagnostic cut-off value and multiple tests in patients with papillary thyroid carcinoma].

To explore the diagnostic cut-off value of Claudin-1 (Cla-1) in papillary thyroid carcinoma (PTC) and the efficacy of the multiple test. Clinical and pathological data were collected from 295 patients with PTC and 137 patients with benign thyroid lesions (BTL) admitted to two hospitals in Pingdingshan City, Henan Province from January 2015 to June 2020. The expression index of Cla-1, the positive expression rate of high molecular weight cytokeratin (HMW-CK) and the negative expression rate of leukocyte differentiation antigen 56 (CD56) were calculated according to the results of immunohistochemistry.

[Clinicopathological features of basal cell type dysplasia of esophagus].

To investigate the clinicpathological features of basal cell type dysplasia of the esophagus. The clinicopathological data of 71 cases of basal cell type dysplasia of esophagus were collected at the People's Liberation Army Joint Logistics Support Force 989 Hospital, from 2009 to 2019, and the histomorphologic characteristics and immunophenotype were evaluated. The relevant literature was reviewed.

[Clinicopathological features of basal cell layer type high-grade squamous dysplasia of the esophagus].

To investigate the clinicopathological features of basal cell layer type high-grade squamous dysplasia of the esophagus. Fifty-two cases of basal cell layer type high-grade squamous dysplasia of the esophagus were collected at PLA Joint Logistics Support Force 989 Hospital (34 cases) and Beijing Chaoyang Hospital (18 cases) from 2009 to 2019. The clinical, histological and immunohistochemical features were characterized.

[Pathological characteristics of colorectal adenoma with submucosal pseudoinvasion].

To investigate the pathomorphological characteristics of colorectal adenoma with submucosal pseudoinvasion and to summarize the corresponding pseudoinvasion patterns. The clinicopathological data of 9 cases of colorectal adenoma were collected at 989 Hospital of PLA Joint Logistics Support Force (4 cases) and Beijing Chaoyang Hospital, Capital Medical University (5 cases), from 2016 to 2019. retrospectively, and the histomorphological characteristics and immunophenotypes were analyzed, and discussed in light of the relevant literature.
