Scattered lymphocytic infiltration in the lamina propria of the colorectal mucosa is mostly suggestive of the presence of intestinal inflammation. It can be seen in bacterial enteritis, parasitic enteritis and other specific enteritis, but also in ulcerative colitis, Crohn’s disease and other non-specific enteritis. 1. Specific enteritis: mostly intestinal inflammation caused by specific pathogenic factors. Such as tuberculosis infection, salmonella infection, parasitic infection, etc., give the corresponding drug treatment can be cured. For example, rifampicin and streptomycin for tuberculosis; norfloxacin and levofloxacin for salmonella; albendazole and mebendazole for parasites. 2. Non-specific enteritis: it is mostly an intestinal inflammation caused by non-specific pathogenic factors, which is related to diet, environment, heredity, infection and other factors. Common ulcerative colitis, Crohn’s disease, etc., mostly incurable. Commonly used drugs include mesalazine, methylprednisolone, cyclophosphamide and so on. For cases of scattered lymphocytic infiltration in the lamina propria of the colon mucosa, it is recommended that corresponding treatment be given after the specific type of disease is clarified.
