primary colorectal lymphoma (pcl) is a rare condition that accounts for a small percentage of all gastrointestinal (gi) malignancies. there are several reports in the literature regarding the most common features of pcl. however, primary lymphoma in the rectosigmoid junction has been rarely reported. our case was a 67-year-old male who presented with non-specific symptoms of bowel obstruction w...

Early diagnosis is often difficult because of unspecific symptoms, with subsequent delays in diagnosis and management. We describe a rare case of colonic lymphoma presenting with synchronous liver metastasis. CASE PRESENTATION A 70-year-old male with a 6-mo history of vague abdominal pain, constipat...

Malignant lymphomas involve the gastrointestinal tract either as primary neoplasms or as part of disseminated disease. Primary lymphoma of the colon is rare, constituting 0.4 % of all colonic malignancies. Non-Hodgkin lymphoma accounts for almost all colonic lymphomas.1-3 The signs and symptoms of colonic lymphoma are non-specific. The lack of specific symptoms can be the reason for delayed dia...

Primary colonic lymphoma is an increasingly recognised complication of ulcerative colitis. We report the first known case of rectal lymphoma occurring after colectomy and ileorectal anastomosis in ulcerative colitis.

diffuse large b cell lymphoma is the most common type of non-hodgkin's lymphoma, representing nearly one-third of all cases. any organ can be involved, making a diagnostic biopsy imperative. when the lungs are the involved organs, it is called primary pulmonary lymphoma (ppl). hereby, we present a case of primary pulmonary lymphoma (ppl) that demonstrated a single large mass on chest ct and had...

non-hodgkin lymphoma (nhl) is one of the masquerade syndromes of malignant melanoma that can occur with two main patterns of presentations in the eye: metastatic involvement of uveal tract, and primary involvement of retina. we report ophthalmic, imaging and histopathological findings in the first case diagnosed as primary choroidal nhl without central nervous system or systemic involvement. a ...
