то, что у вас описали, здесь называется лимфоцитарный/микроскопический колит
Lymphocytic extravasation with >2 lymphocytes/10 enterocytes is generally seen in LC; however, this alone is insufficient to diagnose LC. Additional features such as increased lamina propria inflammatory cells in the upper half of the mucosa and epithelium damage must be present....
Lymphocytic colitis is also seen in middle-aged patients but has a more equal female-to-male ratio. Lymphocytic colitis is defined by increased intraepithelial lymphocytes, with the median being 30 lymphocytes per 100 epithelial cells. There are also an increase in inflammatory cells in the lamina propria, but the increase may be milder than in collagenous colitis and there are usually minimal eosinophils. Although numerous studies have described lymphocytic colitis causing a chronic diarrhea, more recent studies suggest that patients may have a single attack in approximately 60% of cases. Although most cases of lymphocytic colitis are idiopathic, there is a clear association with multiple drugs, celiac disease, and there may be an infectious trigger. Approximately 10% of lymphocytic colitis patients have a positive family history of some type of inflammatory intestinal disease, including ulcerative colitis, Crohn's disease, collagenous colitis, and celiac disease. Therapy in lymphocytic colitis is less well studied, but the same medications are used with success, including budesonide and high dose bismuth.
не попадалось описания биопсии при стерко-колите, так как его диагностируют по КТ-признакам
