CHRONIC LYMPHOCYTIC-LEUKEMIA - AN UNUSUAL CAUSE OF UPPER GASTROINTESTINAL HEMORRHAGE

In contrast to the acute leukemias, chronic lymphocytic leukemia (CLL) is a hematological malignancy with a generally good prognosis. Gastro intestinal (GI) involvement with CLL is unusual, and GI complications generally occur after malignant transformation to diffuse large cell l ymphoma (Richter's syndrome), We present a case of CLL directly infilt rating the gastroesophageal junction resulting in upper GI hemorrhage, This is only the second such case in the literature. We emphasize the consideration of direct leukemic infiltration in addition to Richter' s syndrome in the differential diagnosis of GI bleeding in patients wi th CLL, Whereas the prognosis of Richter's syndrome is poor, CLL invol vement of the GT tract may respond to treatment with chemo- or radioth erapy.
