Synchronous primary gastric mantle cell lymphoma and early gastric carcinoma: a case report

Mantle cell lymphoma (MCL) commonly invades the gastrointestinal (GI) tract. However, primary GI MCL is rare. We experienced a case of synchronous early gastric cancer (EGC) with primary gastric MCL found as a single early lesion rather than as multiple lymphomatous polyposis.

An EGC was found in the cardia of a 64-year-old male on a routine GI endoscopic examination. A specimen obtained by total gastrectomy revealed another slightly elevated lesion in the pylorus. Microscopically, monotonous small- to medium-sized atypical lymphocytes with angulated nuclei formed a mass beneath the gastric mucosa. On immunohistochemical staining, the tumor cells revealed strong positivity for cyclin D1, positivity for both CD20 and bcl-2, and weak positivity for CD5, suggesting MCL. Clinically, there was no lymphoma in any other part of the body.

This is the first case of an EGC accompanying a primary gastric MCL. Further investigation of a relationship between MCL and EGC and of factors that may affect GI involvement of MCL is necessary.     

Primary mantle cell lymphoma of the conjunctiva: a case report

Primary non-Hodgkin’s lymphomas of the conjunctiva are uncommon. They are almost exclusively extranodal marginal zone B-cell lymphomas/mucosa-associated lymphoid tissue lymphomas. In this study, we report an extremely rare case of conjunctival mantle cell lymphoma in a 78-year-old man, presenting as a unilateral epibulbar mass.     

Primary hepatic lymphoma with spindle cell components: a case report

Diffuse large B-cell lymphoma (DLBCL) with spindle cell components is extremely rare and often misdiagnosed as carcinoma or sarcoma. Here, we present a case of primary DLBCL with spindle cell components arising in the liver, for which a preoperative diagnosis by needle biopsies was unsuccessful. The patient was a 70-year-old man with a continuous cough. Thoracic computed tomography incidentally detected a mass of 5 cm in diameter in his liver. The initial and second needle biopsies from the liver mass were pathologically diagnosed as suspicious for sarcomatoid hepatocellular carcinoma. He underwent an extended left hepatectomy. Histological examination revealed a diffuse or epithelioid arrangement of round and polygonal cells, mixed with the fascicles of spindle-shaped cells. Immunohistochemically, all the morphological types of tumor cells showed positive reactions for a lymphocytic marker (CD45RB) and B-cell markers (CD20 and CD79a). Double-immunostaining revealed that the spindle-shaped tumor cells expressed CD20, but never expressed alpha-smooth muscle actin. Malignant lymphoma with a spindle cell morphology is quite uncommon, and this variant can be a diagnostic pitfall, especially in tiny biopsy specimens. We emphasize that pathologists should be reminded of lymphoma as a differential diagnosis of spindle cell tumors.     

Transformation of indolent mantle cell lymphoma to pleomorphic mantle cell lymphoma: case report and review of clinical and morphologic variants

We report a case of indolent mantle cell lymphoma with progression to pleomorphic mantle cell lymphoma 8 years after initial presentation. The first lymph node biopsy showed expanded mantle zones composed of uniformly small B lymphocytes. A cyclin D1 immunohistochemical stain was negative and the patient was observed. Eight years later, the patient developed symptomatic splenomegaly. Microscopic examination of the spleen revealed expanded mantle zones with an increased number of large cells with irregular nuclear contours. Immunohistochemistry for cyclin D1 was positive. A repeat cyclin D1 immunohistochemical staining performed on the initial lymph node biopsy was positive, indicating an inadequate initial study. Immunoglobulin heavy-chain gene rearrangement studies confirmed clonal identity. A revised diagnosis of indolent mantle cell lymphoma with progression to pleomorphic mantle cell lymphoma was rendered. The differential diagnosis of mantle cell lymphoma, including clinical and morphologic variants, is discussed.     

Composite mantle cell and follicular lymphoma. A case report

We describe the association of 2 types of small B-cell lymphomas with different morphologic and immunophenotype patterns inside the same lymph node. Morphologically distinct zones were detected and studied with immunohistochemistry analyses. Most of the areas examined were characteristic of classic mantle cell lymphoma (CD20+, CD5+, cyclin D1+) with nodular and mantle zone areas. However, other areas had the morphologic and immunohistochemistry pattern of follicular lymphoma (CD20+, CD10+, Bcl2+). The diagnosis of both lymphomas was confirmed by polymerase chain reaction detection of both Bcl-1 MTC and Bcl-2 MBR rearrangements. DNA degradation in fixed tissue prevented a complete polymerase chain reaction analysis of immunoglobulin heavy chain rearrangements, but a single immunoglobulin H rearrangement was detected at the FR3 locus. These findings confirm the presence of a monoclonal cell population but do not demonstrate the same clonal origin for both lymphoma populations.     

Primary hepatic marginal zone B-cell lymphoma with mantle cell lymphoma phenotype

We report a rare case of primary hepatic lymphoma, Stage II disease, in a 48-year-old male who had a solitary hepatic tumour measuring 4×4.5×3 cm. The tumour showed a nodular growth pattern and lymphoepithelial lesions with bile ducts. Some neoplastic nodules had a non-neoplastic atrophic germinal centre and/or a thin mantle cell layer. Morphologically, the neoplastic cells were centrocyte-like cells or intermediate lymphocytes. They expressed L26(CD20)⁺/LN-1(CDw75)^±/LN-2(CD74)⁺/cyclin D1^– and had a monotypic immunoglobulin of cytoplasmic IgM () on paraffin sections. The neoplastic cells or neoplastic nodules expressed surface IgM⁺/surface IgD^±/Leu-1(CD5)⁺/DRC-1⁺/alkaline phosphatase⁺/B1(CD20)⁺/B4(CD19)^– on fresh frozen sections. We therefore diagnosed this case as primary hepatic marginal zone B-cell lymphoma with mantle cell lymphoma phenotype. We confirm that it is difficult to differentiate extranodal marginal zone B-cell lymphoma (low grade B-cell lymphoma of mucosa-associated lymphoid tissue type; MALT lymphoma) and mantle cell lymphoma.
