Multifocal mantle cell lymphoma in situ in the setting of a composite lymphoma.
OBJECTIVES Mantle cell lymphoma in situ (MCLIS) consists of immunophenotypically defined but histologically inapparent neoplastic cells restricted to narrow mantle zones, without expansion or invasion beyond the mantle zone. We report a unique case of MCLIS associated with a much more manifest nodal marginal zone lymphoma (MZL) in an inguinal lymph node, porta hepatis lymph node, and bone marro...
متن کاملMantle Cell Lymphoma with Multiple Lymphomatous Polyposis Presenting With Intussusceptions
Mantle cell lymphoma is an aggressive type of B-cell non-Hodgkin's lymphoma that originates from small to medium sized lymphocytes located in the mantle zone of the lymph node. The gastrointestinal tract is the predominant site of extranodal involvement in the form of multiple lymphomatous polyposis. Multiple lymphomatous polyposis due to mantle cell lymphoma presenting with intussusception is ...
متن کاملA unique composite follicular lymphoma and mantle cell lymphoma with a mixed cell pattern and aggressive course.
OBJECTIVES There are a limited number of reports of composite follicular lymphoma (FL) and mantle cell lymphoma (MCL) in the literature, and all previous cases report that FL and MCL components are separated, even within a single lymph node. Here we report a case of a patient with a distinctive composite FL and MCL with a mixed cell pattern. METHODS A 34-year-old man presented with left supra...
متن کاملA Rare Presentation of In Situ Mantle Cell Lymphoma and Follicular Lymphoma: A Case Report and Review of the Literature
A 65-year-old gentleman presented with left groin swelling over the course of two months. Physical exam revealed nontender left inguinal adenopathy, and computed tomography scans detected multiple lymph nodes in the mesenteric, aortocaval, and right common iliac regions. An excisional lymph node biopsy was performed. Pathologic evaluation demonstrated follicular center site which stained positi...
متن کاملLYMPHOID NEOPLASIA Mantle cell lymphoma activation enhances bortezomib sensitivity
Patients with mantle cell lymphoma (MCL) typically respond to initial treatment but subsequently relapse. This pattern suggests that a population of MCL cells is both drug resistant and capable of clonogenic growth. The intracellular enzyme retinaldehyde dehydrogenase (ALDH) provides resistance to several toxic agents. ALDH can also identify stem cells in normal adult tissues and tumorigenic ca...
