Article Abstract
Background: Lymphocytic Esophagitis (LyE) and Eosinophilic Esophagitis (EoE) share many clinical and endoscopic features. However, their treatment outcomes and prognoses differ significantly. LyE, the least recognized form of esophagitis, requires further research. This study compares symptoms, risk factors, and endoscopic findings in LyE and EoE patients.
Methods: This study reviewed medical records, esophagogastroduodenoscopy (EGD) findings, and biopsy data. Patients aged 18 years and older who underwent EGD-guided segmental esophageal biopsies between March 2018 and January 2024 were included. Demographic data, clinical features, risk factors, and EGD findings were compared between LyE, EoE, non-specific esophagitis (NSE), and normal esophageal histology (NEH) groups. The NSE and NEH groups served as controls.
Results: The cohort included 11 LyE cases (1.25%), 79 EoE cases (8.96%), 447 NSE cases (50.68%), and 345 NEH cases (3.11%). LyE patients were older, with a mean age of 54.81 years, and 72.72% of them were female. In contrast, EoE patients were younger, with a mean age of 43.52 years, and had a male predominance. Cases of dysphagia, dyspepsia, and nausea or vomiting occurred in both groups. Food impaction was more frequent in EoE. Smoking, alcohol use, and autoimmune diseases (e.g., hypothyroidism and rheumatoid arthritis) were significant risk factors for LyE. Atopic conditions such as asthma and allergies were linked to EoE. Endoscopic findings often overlapped in LyE and EoE. Esophagitis and strictures were more common in LyE, while rings and furrows were more frequent in EoE. All endoscopic findings, including normal mucosa, were significant in LyE and EoE compared to controls. However, rings, linear furrows, and exudates were not significant when comparing LyE to controls.
Conclusion: LyE is a rare form of esophagitis with clinical and endoscopic features similar to EoE. Accurate histopathological diagnosis is essential for differentiation. LyE is more common in older females with autoimmune conditions, while EoE affects younger males with atopic conditions.

Lichenoid Esophagitis: A Clinicopathological Comparison with Lymphocytic and Eosinophilic Esophagitis.

Department of Medicine DIMED. General Anatomic Pathology and Cytopathology Unit; University of Padova, Padova, Italy.
Background And Aims: Lichenoid esophagitis (LichE) is rarely encountered by gastrointestinal endoscopists. Using a large nationwide database of clinicopathological records, the demographic and clinical characteristics of patients with LichE were compared to patients with lymphocytic esophagitis (LyE) and eosinophilic esophagitis (EoE).
Methods: In a case-control study, cases with a diagnosis of LichE, LyE, or EoE were compared to a control population of all patients without these 3 conditions.

Introduction: Lymphocytic esophagitis (LyE) is a rare esophageal disorder of unknown etiology, characterized by dense peripapillary lymphocytes without neutrophils or eosinophils, and spongiosis. Patients typically present with symptoms such as dysphagia or chest pain. Here, we describe a notable case of lymphocytic esophagitis in a patient who presented with food impaction.

Article Synopsis
- Lymphocytic esophagitis (LyE) and eosinophilic esophagitis (EoE) are both immune-mediated diseases affecting the esophagus, but they have distinct clinical features and treatment outcomes.
- An international retrospective study examined 35 LyE patients compared to 59 EoE patients, focusing on their demographics, symptoms, and endoscopic findings.
- The study found that LyE patients responded less effectively to proton pump inhibitors and highlighted the need for more research on the treatment differences between the two conditions.

Objective: Unlike eosinophilic esophagitis (EoE), there is no consensus on the minimum number of intraepithelial lymphocytes (IEL) that is diagnostic of lymphocytic esophagitis (LyE). The aim of this study was to determine whether significant correlations exist between the numbers of intraepithelial lymphocytes (IEL) in esophageal biopsies and clinical and endoscopic manifestations usually associated with EoE.
Methods: H&E slides from esophageal biopsies from 330 patients were reviewed.
