Precursor B Lymphoblastic Lymphoma Involving the Stomach
نویسندگان
چکیده
Precursor B lymphoblastic lymphoma is a high-grade neoplasm arising from precursor lymphocytes of B-cell lineage. Extranodal sites such as the skin and bone are often involved, but gastrointestinal lesions of this disease are rarely encountered. Due to the infrequency, macroscopic forms of the gastrointestinal lesions have not been fully described. In this report, we present a case of precursor B lymphoblastic lymphoma involving the stomach, pancreas, bone, and bone marrow. Esophagogastroduodenoscopy showed multiple flat elevated lesions with irregular mucosa in the stomach.

Precursor B-lymphoblastic lymphoma involving an intracardiac mass and myocardial infiltration: a case report.
We report the case of a 17-year-old man with precursor B-lymphoblastic lymphoma involving an intracardiac mass and myocardial infiltration. Intensified chemotherapy followed by autologous peripheral blood stem cell transplantation resulted in long-term complete remission for over 5 years. As the most frequent sites of B-lymphoblastic lymphoma involvement are the skin, soft tissue, bone, and lym...
متن کاملPrimary spinal epidural B-lymphoblastic lymphoma.
Extranodal lymphomas constitute 20% to 30% of all non-Hodgkin's lymphomas. The common sites involved are skin, stomach, brain, and small intestine. Epidural localization is a rare site for lymphomas, accounting for 10% of spinal epidural tumors. Lymphomas occurring primarily in the epidural space without other previously detected lymphomatous foci (i.e., primary spinal epidural lymphomas) repre...
متن کاملMYC Rearrangement Involving a Novel Non-immunoglobulin Chromosomal Locus in Precursor B-cell Acute Lymphoblastic Leukemia
MYC rearrangement, a characteristic cytogenetic abnormality of Burkitt lymphoma and several subsets of other mature B-cell neoplasms, typically involves an immunoglobulin gene partner. Herein, we describe a case of precursor B-cell lymphoblastic leukemia harboring a MYC rearrangement with a novel non-immunoglobulin partner locus. The patient was a 4-yr-old Korean boy with ALL of the precursor B...
متن کاملLymphoblastic lymphoma of the palate.
Lymphoblastic lymphomas are neoplasms of immature or precursor lymphoid cells with no or limited bone marrow involvement, whose clinical presentation varies according to the immunophenotype. While mediastinal involvement is predominant in T-lymphoblastic lymphomas, B-lymphoblastic lymphomas frequently involve nodal sites. Extranodal presentation of B-lymphoblastic lymphomas is extremely rare. W...
متن کاملLymphocyte malignancy and chromosome 14: structural aberrations involving band q11.
Five patients with lymphocytic malignancies were found to have structural aberrations of chromosome 14, all involving band q11. The malignant cells of all five cases were analyzed by immunofluorescence to establish immunologic phenotypes. Three patients had T lymphoblastic lymphoma/leukemia with mediastinal masses (cases 1, 2, and 3); one patient had peripheral T cell lymphoma (case 4); and one...
