Cecal MALT lymphoma: a challenging diagnosis

MALT lymphoma of the colon: an endoscopic challenge

Colonic lymphoma involving the mucosa-associated lymphoid tissue (MALT) is an uncommon pathology, with an unknown pathogenesis and varied endoscopic appearance. We present the case of a 78-year-old female with challenging endoscopic findings that resulted in the diagnosis of a colonic MALT lymphoma.

Digestive tract MALT lymphoma, an unusual location

The authors describe a case of a rectal mucosa-associated lymphoid tissue lymphoma in a 78-year-old female patient, manifested as rectal bleeding. Despite being commonly diagnosed in the localized form, this patient had supradiaphragmatic involvement on disease staging. Immunochemotherapy was proposed due to the disseminated involvement and poorer prognosis.
