چکیده

The development of extranodal lymphomas is thought to be initiated by the transformation event in peripheral organs. Lymphomatoid papulosis (LyP) is a low-grade cutaneous lymphoma and may progress into the cutaneous anaplastic lymphoma. We identified 2 patients who 3 and 4 years before the development of LyP were treated for an unrelated malignancy (Burkitt lymphoma and small-cell B-cell lymphoma). We analyzed the T-cell receptor (TCR) gene rearrangement pattern in their skin, blood, and bone marrow, including the archival bone marrow sampled years before the development of clinically evident LyP. In all samples we detected the unique monoclonal TCR rearrangements. This observation suggests that the initial malignant transformation in LyP occurred in bone marrow and not, as could be supposed, in the skin.

Case series of precursor B-cell lymphoblastic lymphoma

Precursor B-cell lymphoblastic lymphoma (B-LBL) is an uncommon subtype of Non-Hodgkin lymphoma (NHL), accounting for only 0.3% of NHL in adults and less than 10% of all LBL cases. Unlike T-cell LBL, it usually presents with extranodal involvement while sparing the bone marrow (BM). Among the 27 patients with LBL treated in the Asan Medical Center between January 2007 and March 2012, 3 had B-LBL...

Lymphoblastic 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...

Extranodal NK/T-cell lymphoma, nasal type extensively involving the bone marrow.

Extranodal NK/T-cell lymphoma, nasal type, is an aggressive EBV-associated lymphoma that mainly involves the nasal cavity but has also been reported to involve other extranodal sites without nasal involvement. In contrast to aggressive NK cell leukemia (a marrow-based aggressive leukemia of NK-cell origin); extensive bone marrow and blood involvement is extremely uncommon by nasal type NK/T lym...

Precursor B Lymphoblastic Lymphoma Involving the Stomach

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...

Extranodal NK/T Cell Lymphoma with Destruction of the Uvulae: A Case Report

Introduction: Extranodal Natural Killer (NK)/T-cell lymphoma (NKTCL) nasal type is a rare but well-known disease with poor prognosis. NKTCL is more prevalent in Asia and comprises about 7-10% of all non-Hodgkin lymphoma cases in this region. The characteristic clinical pattern of NKTCL is the destruction of the midline structures of the mid-face. Case Report: The present study examines a case o...
