OBJECTIVES:
Immunophenotyping technique is a powerful tool for the diagnosis and differential diagnosis of chronic lymphocytic leukemia (CLL) and other B-cell chronic lymphoproliferative diseases (B-CLPD). CD200 is strongly expressed in CLL. This study aims to analyze the clinical value of modified Matutes score (MMS) containing CD200 in the diagnosis of CLL.
METHODS:
We retrospectively analyzed 103 B-CLPD patients diagnosed from January 2020 to July 2021, including 64 CLL patients, 11 follicular lymphoma (FL) patients, 14 mantle cell lymphoma (MCL) patients, 6 marginal zone lymphoma (MZL) patients, 1 hairy cell leukemia (HCL) patient, and 7 lymphoplasmic lymphoma/Waldenstrom macroglobulinemia (LPL/WM) patients. The expression of CD markers between the CLL group and the non-CLL group was compared, and the sensitivity, specificity, and clinical consistency of MMS and Royal Marsden Hospital (RMH) immunophenotyping score system were analyzed.
RESULTS:
There were significant differences in the expressions of CD5, CD23, FMC7, CD22, CD79b, CD200, and sIg between the CLL group and the non-CLL group (χ2 values were 37.42, 54.98, 30.71, 11.67, 55.26, 68.48, and 17.88, respectively, all P<0.01). When the RMH immunophenotyping score≥4, the sensitivity was 79.7%, and the specificity was 100%. When the MMS≥3, the sensitivity was 95.3%, and the specificity was 100%. The Kappa coefficient of RMH immunophenotyping system was 0.677, and the Kappa coefficient of MMS system was 0.860.
CONCLUSIONS
The MMS system containing CD200 has better sensitivity and same specificity compared with RMH immunophenotyping system, and MMS system may be more useful in the diagnosis of CLL.

BACKGROUND: In the skin, it is often difficult to differentiate lymphomas from reactive lymphoid lesions by light microscopic examination. OBJECTIVE: Our purpose was to determine whether immunologic data obtained from mutine-processed specimens could be used to further objective morphologic interpretations. METHODS: We conducted an immunohistochcmical staining in 44 cases of benign and malignant cutaneous lymphoproliferative lesions using nine antibodies, including anti-CD3, UCHL1, MT1, MT2, L26, MB2, BerH2, 123C3, and MIB1. RESULTS: 1. Immunophenotyping with anti-CD3, UCHL1, MT1, L26, and MB2 was useful for the diagnosis of T cell or B cell lymphoma. However, these antibodies showed a lack of specificity for neoplastic cells, 2. Antibody to CD56, 123C3 showed positivity in 4 cases of angiocentric lymphoma, but negativity in 8 cases showing angiocentric lymphoma-like pathology. 3. Antibody to CD30, BerH2 showed positivity in all 6 cases of CD30 positive large cell lymphoma, but negativity in 6 cases showing diffuse lymphoma-like pathology. 4. Antibody to Ki-67, MIB1 showed positivity in more than 30% of infiltrating cells in 6 cases of angiocentric lymphoma, 4 cases of diffuse B cell lymphoma, and in more than 60% of infiltrating cells in 6 cases of CD30 positive large cell lymphoma. CONCLUSION: These observations suggest that immunostaining may provide useful adjunctive information in distinguishing benign from malignant cutaneous lymphoproliferations in paraffin sections.

To investigate the clinical manifestations, imaging features, and diagnosis for non-Hodgkin's lymphoma in the jaw, we retrospectively analyzed 3 cases of non-Hodgkin's lymphoma in the jaw and reviewed relevant literature. Three patients' lesion occurred in the maxilla with early painless masses. Two patients were diagnosed as diffuse large B-cell lymphoma via biopsy, and one patient underwent maxillofacial resection with pathological examination which showed plasmaoblastoma lymphoma. Non-Hodgkin's lymphoma in the maxilla is rare and easily misdiagnosed due to the atypical clinical features. Biopsy at the early stage of the lesion and pathological examination can assist the diagnosis for non-Hodgkin's lymphoma.

We report here on a case of non-Hodgkin's lymphoma in which liver involvement was the predominant clinical manifestation. A healthy 44-year-old man presented with upper abdominal pain, hepatosplenomegaly, thrombocytopenia, elevated AST, ALT and bilirubin, and marked elevation of lactate dehydrogenase and alkaline phosphatase. The abdominal CT scan showed only diffuse hepatosplenomegaly and uneven contrast enhancement of the spleen without any definite mass of the liver and spleen. US-guided aspiration biopsy of liver and the histologic examination confirmed a diagnosis of non-Hodgkin's lymphoma, the diffuse large B cell type. Bone marrow biopsy showed the infiltration of malignant lymphoma cells. PET-CT showed an increased FDG uptake of the liver, spleen and long bones. The patient was treated with combination regimen of cyclophosphamide, doxorubicin, vincristine and prednisone chemotherapy. Even in the absence of a mass lesion or lymphadenopathy, primary hepatic or hepatosplenic lymphoma should be considered in differential diagnosis of hepatitis or liver cirrhosis, especially for patients with diffuse hepatosplenomegaly and markedly elevated LDH.

Primary splenic lymphoma (PSL) is often defined as generalized lymphoma with splenic involvement as the dominant feature. It is a rare disease that comprises approximately 1% of all malignant lymphomas. We investigated three cases of non-Hodgkin's splenic lymphoma that had different clinical features on presentation. The patients' survival times from diagnosis ranged from 59 to 143 months, without evidence of relapse after splenectomy and chemotherapy, with or without radiotherapy. This data suggest that PSL is potentially curable. Further studies are needed to evaluate the impact that different treatment modalities without splenectomy have on patient survival.

Primary pancreatic lymphoma is rare, comprising 0.2~4.9% of all pancreatic malignancies and less than 1% of cases of non-Hodgkin's lymphoma. Many patients are diagnosed with lymphoma after radical resection. We report a rare presentation of diffuse large B cell lymphoma, appearing as a primary tumor of the pancreas. A 61-year old female was admitted to the hospital with the complaint of right upper abdominal pain. Computed tomography of the abdomen showed a well defined mass located at the head of the pancreas. A frozen section of pancreas, during laparotomy, revealed lymphoma. The patient received 6 cycles of chemotherapy and is currently in complete remission. This case underscores the importance of differentiating primary lymphoma from the more common adenocarcinoma of the pancreas as treatment and prognosis differ significantly. Primary pancreatic lymphoma should be considered in the differential diagnosis of pancreatic tumors and an attempt to obtain a tissue diagnosis is always necessary before proceeding to radical surgery, especially on young patients.
