Summary
A rare ileal papilloma was identified in a Sprague-Dawley rat. This study documents the first occurrence of this specific intestinal tumor in rats within Bangladesh.
Area of Science:
- Veterinary Pathology
- Gastrointestinal Oncology
Background:
- Spontaneous tumors in laboratory animals are crucial for understanding disease mechanisms.
- The Sprague-Dawley rat is a common model organism in biomedical research.
Purpose of the Study:
- To report the first documented case of spontaneous ileal papilloma in a rat in Bangladesh.
- To describe the histological characteristics of this rare intestinal neoplasm.
Main Methods:
- Gross examination of the abdominal cavity and intestinal tract.
- Histopathological analysis of the ileal lesion, including evaluation of epithelial changes.
Main Results:
- A spontaneous ileal papilloma was observed in a 1.5-year-old female Sprague-Dawley rat.
- Histology revealed a papilloma with significant hyperkeratosis, hyperplasia, and acanthosis of the transformed epithelium.
Conclusions:
- This case represents the first reported instance of ileal papilloma in a rat in Bangladesh.
- The findings contribute to the understanding of spontaneous gastrointestinal neoplasms in rodent models.
