ABSTRACT
Immunoproliferative small intestinal disease (IPSID) is a rare type of indolent B-cell lymphoma. It is a variant of extranodal marginal zone B-cell lymphoma of mucosa associated lymphoid tissue. It is commonly seen in older children and young adults in the age group of 10-35 years. It is more common in males with Male: Female ratio of 2.4:1. Duodenum and jejunum are the commonly involved areas in small intestine. Colicky abdominal pain and intermittent diarrhoea are the common symptoms. Here by, we report a rare case in a 74-year-old male patient presented with chief complaints of abdominal pain, diarrhea and weight loss for 3 months. CT scan findings revealed thickening of small intestinal wall and mesenteric lymphadenopathy. Upper gastrointestinal endoscopy findings revealed nodular and ulcerative mucosa in the duodenum. Histopathological examination revealed flattening of mucosa with villous atrophy, destruction of crypts and intraepithelial lymphocytic infiltrate is noted. Interstitium shows dense and diffuse collection of lymphoplasmacytic infiltrate. Immunohistochemistry was done and it showed CD20 positive lymphoid cells. Based on the above findings the case was reported as Immunoproliferative small intestinal disease. Clinicians should suspect IPSID in cases presenting with chronic diarrhea and abdominal pain refractory to treatment. Immunoproliferative small intestinal disease has indolent clinical course and it can be cured with antibiotics in early stages. Late stages have high mortality rate and has poor prognosis.
