A pathologist is reviewing gastrointestinal mucosal biopsies from several patients presenting with chronic gastrointestinal symptoms. Match each of the following specific histological biopsy findings to its corresponding definitive pathologic diagnosis.
- Lamina propria expansion by large macrophages containing PAS-positive, diastase-resistant structuresWhipple disease
- Increased intraepithelial lymphocytes, crypt hyperplasia, and marked villous atrophy in the proximal small intestineCeliac disease
- Transmural lymphocytic inflammation with deep fissuring ulcers and noncaseating granulomasCrohn disease
- Continuous diffuse mucosal inflammation extending proximally from the rectum, featuring crypt abscesses and mucin depletionUlcerative colitis
- Squamous mucosa with >15 intraepithelial eosinophils per high-power field and basal zone hyperplasiaEosinophilic esophagitis
Cevap
Each histological description definitively maps to a classic gastrointestinal pathology based on specific cellular infiltrates and architectural changes (Whipple, Celiac, Crohn, Ulcerative Colitis, and Eosinophilic Esophagitis).
The correct matches represent the consensus diagnostic criteria for these distinct gastrointestinal conditions. Biopsy interpretation relies on identifying the specific combination of inflammatory cells (eosinophils, lymphocytes, macrophages), their location (intraepithelial, lamina propria, transmural), and the resulting tissue damage (villous atrophy, crypt distortion, ulceration).

Anahtar Kavram
Definitive diagnosis of chronic gastrointestinal inflammatory and infectious disorders requires integrating specific histopathological architectural changes, cellular infiltrates, and histochemical staining patterns.
