Abstract
Primary gastrointestinal lymphoma is a rare entity, commonly involving stomach, small bowel, and colorectum. The usual location for small bowel B cell lymphoma is distal ileum due to abundant lymphoid tissue. We are reporting the case of a 53-year-old lady presumptively diagnosed as Crohn's disease on clinical and radiological grounds but histopathologically proven to be an unusual variant of isolated primary non-Hodgkin's lymphoma.
Highlights
Gastrointestinal (GI) lymphomas may clinically be confused with other GI tumours as well as with inflammatory bowel disease
GI lymphomas arise from the lymphoid tissue within the wall of small intestine which is abundant in the ileum
Primary GI lymphoma is usually localized to a single segment of the intestine, with multicentricity seen in 15–20% of cases [1]
Summary
Gastrointestinal (GI) lymphomas may clinically be confused with other GI tumours as well as with inflammatory bowel disease. The small intestine is the site of origin of about 15–25% of primary GI lymphomas, with stomach being the most common site affected. Primary GI lymphoma is usually localized to a single segment of the intestine, with multicentricity seen in 15–20% of cases [1]. We report the rare case of a 53-year-old lady presenting with features, which was clinic-radiologically diagnosed to be jejunal stricture secondary to Crohn’s disease (CD) on the basis of clinical and radiological features and was reported to be a case of non-Hodgkin’s lymphoma (NHL) of B cell type (uncommon in jejunum) on histological evaluation. Our report emphasizes the importance of considering lymphoma in the differential diagnosis of jejunal stricture presenting with small bowel obstruction
