Multifocal Mantle Cell Lymphoma In Situ in the Setting of a Composite Lymphoma

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...

In situ mantle cell lymphoma in the nasopharynx.

BACKGROUND Mantle cell lymphoma (MCL) is a B-cell neoplasm with an aggressive clinical course. Recently, an indolent type of MCL has been described under the term in situ MCL. METHODS AND RESULTS We report a case of a 70-year-old woman who presented with nasal obstruction. A mass, located in the nasopharynx, was found. Histologic examination revealed lymphoid hyperplasia characterized by CD5 ...

Mantle 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 ...
