Match each of the following gastrointestinal disorders with its classic characteristic endoscopic or histopathologic finding.

  • Crohn diseaseTransmural inflammation with noncaseating granulomas
  • Ulcerative colitisContinuous mucosal inflammation with crypt abscesses
  • Celiac diseaseVillous atrophy with intraepithelial lymphocytosis
  • Whipple diseasePAS-positive macrophages in the lamina propria

Cevap

Crohn disease maps to transmural inflammation with noncaseating granulomas; Ulcerative colitis maps to continuous mucosal inflammation with crypt abscesses; Celiac disease maps to villous atrophy with intraepithelial lymphocytosis; Whipple disease maps to PAS-positive macrophages in the lamina propria.
Each gastrointestinal disorder has highly specific and distinct pathological features that define its diagnosis and distinguish it from other similar conditions.

Adım Adım Çözüm

1
Analyze the histopathologic findings associated with inflammatory bowel diseases.
Identify that transmural inflammation and noncaseating granulomas are hallmarks of Crohn disease, while continuous mucosal inflammation and crypt abscesses indicate Ulcerative colitis.
Differentiating between the two main types of inflammatory bowel disease is a fundamental clinical skill.
2
Evaluate the classic biopsy findings for small bowel malabsorption disorders.
Correlate villous atrophy and intraepithelial lymphocytosis with Celiac disease, and link PAS-positive macrophages to Whipple disease.
These specific microscopic features are pathognomonic and essential for definitive diagnosis of these conditions.
