Peritoneal lymphomatosis mimicking peritoneal carcinomatosis - a clinical dilemma: Series of two cases and review of literature

Abstract

Peritoneal lymphomatosis is a rare presentation of non-Hodgkin lymphoma and most often associated with abdominal organ involvement. The diagnosis is often difficult and needs to be differentiated from peritoneal carcinomatosis and tubercular peritonitis. Imaging, though helpful in disease staging, may not lead to a specific diagnosis; which rests on the histopathological findings. We present two cases of peritoneal lymphomatosis with different presentations and extranodal sites of involvement.
