Which condition may feature fat-laden histiocytes in the gastric mucosa?
Show Hint
Gastric xanthoma (fat-laden histiocytes) is tied to chronic bile reflux, and shows up most often in the gastric remnant after gastrectomy.

- Signet ring cell carcinoma
- Erosive gastritis
- Post-gastrectomy status
- Lymphoma
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: Name the histology first.
Foamy, lipid filled macrophages sitting inside the gastric lining have a specific name, gastric xanthoma. They form wherever the mucosa keeps getting damaged and macrophages keep cleaning up broken cell membranes rich in fat.
Step 2: Ask what keeps injuring the mucosa.
Chronic bile exposure is the classic trigger. Bile acids are detergents, they break down the epithelial lining over time and release lipid that macrophages then engulf.
Step 3: Connect this to surgery.
Once part of the stomach and the pylorus are removed in a gastrectomy, bile from the duodenum refluxes freely into the remaining pouch. This repeated bile exposure is exactly the setting where gastric xanthomas are reported most often.
Step 4: Compare with the distractors.
A signet ring tumor is defined by mucin filled malignant cells, not macrophages. Erosive gastritis is about mucosal breaks and acute inflammatory cells. Lymphoma is a lymphocyte proliferation. None of these three match a histiocyte, lipid based picture the way post-gastrectomy bile reflux does.
