Match each of the following clinical presentations with the most likely diagnosis.
- A 45-year-old man presents with chronic diarrhea, profound weight loss, migratory polyarthralgia, and subtle cognitive decline. Small bowel biopsy reveals periodic acid-Schiff (PAS)-positive, diastase-resistant inclusions in lamina propria macrophages.Whipple disease
- A 32-year-old woman presents with chronic diarrhea, weight loss, severe iron deficiency anemia, and an intensely pruritic, papulovesicular rash on her elbows and knees.Celiac disease
- A 58-year-old man presents with episodic, intense facial flushing, chronic watery diarrhea, and a newly auscultated holosystolic murmur at the left lower sternal border that increases with inspiration.Carcinoid syndrome
- A 40-year-old woman presents with massive volumes of tea-colored watery diarrhea (up to 5 liters daily), severe muscle cramps, and profound muscle weakness. Laboratory testing reveals severe hypokalemia and achlorhydria.VIPoma
Cevap
1 matches with Whipple disease; 2 matches with Celiac disease; 3 matches with Carcinoid syndrome; 4 matches with VIPoma.
Each clinical presentation aligns precisely with a distinct gastroenterologic syndrome characterized by its pathognomonic features: PAS-positive macrophages for Whipple disease, dermatitis herpetiformis for celiac disease, right-sided heart disease with flushing for carcinoid syndrome, and the WDHA triad for VIPoma.
