| Abstract |
|
|
A localized extramedullary tumor mass composed of immature cells has been reported in
association with acute myeloid leukemia, myeloproliferative disorders, myelodysplasia in blast
transformation or chronic myeloid leukemia with trilineage hematopoiesis, as well as in patients with
no known hematological disorder. Although this tumor may involve anywhere in the body and give
rise to a variety of signs and symptoms, there are several case reports of extramedullary tumor in
Korea which described the involvement of the gastrointestinal tract. We report the occurrence of
gastric extramedullary tumor and lymphoid blast crisis in a patient with complete remission after
lymphoblastic transformation of chronic myelogenous leukemia. Endoscopic biopsy for gastric
elevated lesion showed diffuse lymphoblast infiltration with TdT (terminal deoxynucleotidal transfe
rase) and CD20 positive immature cells. (Korean J Gastrointest Endosc 2004;28:8185) |
