Zorluk: KolayPathology and Biopsy Interpretation

Match the following classic gastrointestinal histopathologic biopsy descriptions with their corresponding definitive clinical diagnoses.

  • Intestinal metaplasia with goblet cells replacing normal stratified squamous epithelium in the distal esophagusBarrett esophagus
  • Transmural inflammation with noncaseating granulomas, lymphoid aggregates, and mucosal skip lesionsCrohn disease
  • Villous atrophy, crypt hyperplasia, and increased intraepithelial lymphocytes in the duodenumCeliac disease
  • Continuous mucosal and submucosal inflammation with crypt abscesses, pseudopolyps, and crypt distortionUlcerative colitis

Cevap

Intestinal metaplasia matches Barrett esophagus; Transmural inflammation with granulomas matches Crohn disease; Villous atrophy matches Celiac disease; Continuous mucosal inflammation with crypt abscesses matches Ulcerative colitis.
Each histopathologic description represents the classic, board-tested biopsy findings required to establish the diagnosis for these common gastrointestinal disorders. Recognizing these direct one-to-one correlations is essential for confirming clinical suspicion with tissue pathology.

Adım Adım Çözüm

1
Analyze the esophageal biopsy findings.
Identified intestinal metaplasia with goblet cells replacing squamous epithelium.
This specific cellular shift directly points to Barrett esophagus, an adaptive response to chronic acid exposure.
2
Differentiate the inflammatory bowel disease (IBD) biopsy findings.
Distinguished transmural inflammation with skip lesions and granulomas (Crohn disease) from continuous, mucosa-limited inflammation with crypt abscesses (Ulcerative colitis).
Accurate IBD differentiation relies on identifying the depth of inflammation and the presence of defining features like granulomas.
3
Analyze the duodenal biopsy findings.
Identified villous atrophy and intraepithelial lymphocytosis.
These findings in the small bowel are the diagnostic gold standard for Celiac disease.
