Primary non-Hodgkin's lymphoma (NHL) of the thyroid gland is a rare disease with an incidence of 0.5 per 100,000 population. Stages IE and IIE thyroid NHL have been traditionally treated by surgical resection; however, modern treatment consists of chemotherapy and local radiotherapy, and surgery is often reserved for tissue diagnosis and relief of airway compression. We retrospectively reviewed the management and outcomes of nine consecutive patients with thyroid NHL, eight females and one male (median age 63 yr, range 34-71 yr) treated between 1994 and 1999. Five patients had disease stage IE and 4 stage IIE. Median follow-up was 72 mo. Pathohistology and immunohistochemistry identified two patients with mucosa-associated lymphoid tissue (MALT), three follicular center cell lymphoma (FCC), two patients large B-cell lymphoma (BLCL), one a marginal zone lymphoma (MZL), and one patient a peripheral T-cell lymphoma (PTCL). Total thyroidectomy was performed in three patients and subtotal thyroidectomy in four. One (MALT) patient underwent surgery alone; three patients surgery, radiotherapy, and chemotherapy (two FCC, one PTCL); three patients surgery and chemotherapy (one MALT, one FCC, one LBCL); and two chemotherapy alone (one LBCL, one MZL). Median survival was 79 mo (range 13-124 mo). The PTCL patient, a 34-yr-old man, died from disseminated disease at 13 mo despite secondary chemotherapy, and one LBCL patient with extensively invasive local disease died from stroke 17 mo after diagnosis. The remaining seven patients remain in remission with no local or systemic relapse at a mean of 86 mo. With appropriate therapy primary thyroid NHL has a favorable course; however, prognosis depends on the histology, local spread, and the stage of the disease at presentation, as well as the patient's performance status. Surgery in combination with chemotherapy and/or radiotherapy is still warranted for intermediate and high-grade thyroid NHLs, with over 77% of patients achieving long-term remission. Peripheral T-cell lymphoma carries a poor prognosis.

Primary testicular non-Hodgkin's lymphoma was first described as a clinical entity in 1866. It is a rare disease and accounts for 1% of all non-Hodgkin's lymphoma, 2% of all extranodal lymphomas and 5% of all testicular neoplasms. It is the most common testicular tumor in males between sixty and eighty years of age. Testicular non-Hodgkin's lymphoma is unique in its high incidence of bilateral involvement (8-38%), and it is also the most common bilateral testicular tumor. Testicular non-Hodgkin's lymphoma has a predilection for spreading to non-contiguous extranodal sites, especially the central nervous system. Advanced-stage disease is usually managed with doxorubicin-based chemotherapy. For early-stage disease, opinion is divided regarding systemic chemotherapy following orchidectomy. The high incidence of spreading, especially to the central nervous system, leads to advocacy of the use of central nervous system prophylaxis with intrathecal chemotherapy. Prospective multicenter trials incorporating a large number of patients may lead to better guidelines for optimal management of this subtype of non-Hodgkin's lymphoma.

Primary splenic lymphoma (PSL) is a rare disease with ambiguous definition, comprising less than 1% of non-Hodgkin's lymphoma. Even rarer is PSL combined with hemophagocytic lymphohistiocytosis (HLH), which has presentations of fever, cytopenia, hepatosplenomegaly, hyperferritinemia, and phagocytosis of hematopoietic cells in the reticuloendothelial system. We report the case of a 77-year-old man who presented with HLH initially. Refusing diagnostic splenectomy, he received chemotherapy. Spontaneous splenic rupture occurred after chemotherapy. In the following emergency operation, PSL was diagnosed. He received another 5 courses of chemotherapy with the R-CNOP regimen (rituximab, cyclophosphamide, mitoxantrone, vincristine, prednisolone). Now he has no residual or relapsed disease. Diagnostic splenectomy for adult HLH patients without definite etiologies may play an important role.

Burkitt's lymphoma is a rare disease that belongs to the aggressive non-Hodgkin's lymphoma. Herein, we report a case of primary hepatic Burkitt's lymphoma. A 19-year-old man visited the hospital for right upper quadrant pain. He felt fatigue for two months. Physical examination revealed hepatomegaly and no palpable lymph node. He had no fever, weight loss, or night sweating. Laboratory finding showed mild anemia (hemoglobin, 12.4 g/dL), mild elevated transaminase (ALT, 52 IU/L), elevated lactate dehydrogenase (LDH, 437 IU/L), and alkaline phosphatase (ALP, 129 IU/L). The viral marker was positive for HBsAg, HBeAg, anti-HBs, and anti-HBc (IgG), and negative for anti-HBe, anti-HCV, and anti-HIV. CEA, AFP, and CA19-9 levels were within normal ranges. The HBV DNA quantitation was 1.3 x 10(9) copies/ml. Abdominal-Pelvis CT scan and abdominal MRI finding were compatible with malignant lymphoma. Liver biopsy examination confirmed Burkitt's lymphoma. No metastasis was detected in the thoracic cavity, bone marrow, and spinal fluid. The patient was treated with the combination regimen of cyclophosphamide, doxorubicin, vincristine, prednisone and high dose methotrexate. Cytosine arabinoside and methotrexate were added for CNS prophylaxis by intrathecal installation. Chemotherapy was administered every 3 weeks for fifteen cycles. Serial follow-up CT scan showed a marked decrease in the size of hepatic lesions. Follow-up CT scan and PET-CT scan were performed 4 weeks after the final cycle disclosed no definite residual or active lesion confirming the state of complete remission.

Immunohistochemical determination of p63 protein is frequently used in the pathologic diagnosis of nonhematological solid tumors. In malignant hematological disease, p63 expression has been reported in 22% of follicular lymphoma, about 35% of diffuse large B-cell lymphoma, 23% of chronic lymphocytic leukemia, and in some cases of blast crisis of chronic myelogenous leukemia. Anaplastic large cell lymphoma is a rare disease that accounts for less than 5% of all cases of non-Hodgkin's lymphoma. There is little information concerning p63 expression in this specific type of lymphoma. In some cases, the morphological and phenotypic features between anaplastic large cell lymphoma and classical Hodgkin's lymphoma are similar, making this differential diagnosis challenging. We studied p63 expression using a tissue microarray approach in 154 cases of anaplastic large cell lymphoma, including 38% anaplastic large cell kinase positive and 62% anaplastic large cell kinase negative, and 58 Hodgkin's lymphoma cases. Sixty-eight cases of anaplastic large cell lymphoma (44%) showed p63 nuclear positivity (41% of anaplastic large cell kinase positive and 47% of anaplastic large cell kinase negative). Of 130 cases of systemic-anaplastic large cell lymphoma, 42% showed p63 positivity. The neoplastic cells expressed p63 in 38% of the cases of CD45-negative/anaplastic large cell kinase-negative null cell-type anaplastic large cell lymphoma, a subgroup that offers the most difficulties in the differential diagnosis with classical Hodgkin's lymphoma. In contrast, none of the cases of classical Hodgkin's lymphoma demonstrated any p63 expression. These results demonstrate that p63 protein expression is frequently expressed in a subset of anaplastic large cell lymphoma cases and may be used as a potential tool in the differential diagnosis between anaplastic large cell lymphoma and classical Hodgkin's lymphoma.

Primary lymphoma of the gallbladder is an exceedingly rare disease. We experienced an asymptomatic case of primary non-Hodgkin's lymphoma of the gallbladder in a 55-year-old woman in whom laparoscopic cholecystectomy made a definite diagnosis. Abdominal computed tomography revealed a 4-cm gallbladder tumor with markedly enlarged lymph nodes in the retropancreatic area. Despite the marked involvement of lymph nodes, serum levels of carcinoembryonic antigen (CEA) and carbohydrate antigen (CA) 19-9 were not elevated. The discrepancy between the imaging findings and the patient's mild clinical presentation led us to suspect that the tumor was a lymphoma. We examined serum markers of lymphoma, revealing slight elevations of interleukin (IL)-2 receptor and thymidine kinase. Laparoscopic cholecystectomy for a total biopsy was performed successfully, and the results of intraoperative frozen-section examination led us to have a high suspicion of malignant lymphoma. The final diagnosis was large diffuse B-cell lymphoma of the gallbladder with a positive CD20 antibody reaction. The patient received postoperative chemotherapy with R-CHOP (rituximab, 500 mg; cyclophosphamide, 1000 mg; adriamycin, 68 mg; vincristine, 1.9 mg; and prednisone, 80 mg) starting on postoperative day 12. She achieved complete remission and is still in complete remission 3 years and 2 months after the cholecystectomy. In conclusion, gallbladder lymphoma should be added to the differential diagnosis of gallbladder tumors, especially when the imaging findings and clinical presentation are not consistent with typical signs of gallbladder carcinoma, and laparoscopic cholecystectomy is helpful for the confirmation of suspicious cases.

Extranodal non-Hodgkin's lymphoma (NHL) is a rare breast disease. Here we report three cases of primary NHL of the breast. The first patient was a 29-year-old woman with a firm mass in her right breast with ipsilateral axillary lymphadenopathy. An excisional biopsy revealed NHLs. Clinical stage was IIAE. The tumor and enlarged lymph nodes had successfully been treated following the combination therapy. The second patient was a 70-year-old women with an elastic hard mass in her left breast. An excisional biopsy revealed NHLs and clinical stage was 1AE. The tumor disappeared following the combination therapy. The third patient was a 67-year-old women with a hard mass in her left breast. Core needle biopsy revealed NHLs and clinical stage was 1AE. The tumor disappeared following chemotherapy. All patients are alive with no evidence of recurrence 4-8 years after the initial treatment. Although a standard treatment has yet to be established, an initial treatment with combination therapy without surgical intervention including axillary dissection appears to be appropriate for this rare disease.

Primary non-Hodgkin's lymphoma of the esophagus is a rare disease. A case of primary isolated non-Hodgkin's lymphoma of the esophagus in a 77-year-old man without acquired immunodeficiency syndrome is presented. We describe the clinical features and the imaging findings (barium swallow, endoscopic ultrasonography and CT) of a biopsy proven B-cell lymphoma with diffuse transmural involvement of the esophagus wall, which was discovered incidentally. We also briefly review the literature.

Natural killer (NK)/T-cell lymphomas represent a rare type of lymphoma derived from either activated NK cells or cytotoxic T cells. They are most commonly extranodal and tend to present as destructive lesions within the midline facial structures. Other than the nasal cavity and Para nasal sinuses, several other extra nodal sites of involvement have been reported, including the pharynx, gastrointestinal tract, and testis. Occasionally, pleural effusion has also been observed. Here, a case of lymphoma of NK/T-cell type presented as pleural effusion was reported. The patient was previously misdiagnosed as B cell non-Hodgkin's lymphoma by pathological and immunohistochemistry (IH) analysis for pleural membrane biopsy specimen. After the analysis of the pleural fluid cells by a combination of morphologic, immunophenotypic, cytogenetic and molecular (MICM) methods in Beijing Dao-Pei hospital, some lymphoblasts were found morphologically, which expressed cytoplasmic CD3 (cCD3) and CD56 by flow cytometry analysis and had a clonal T-cell receptor gamma (TCR-gamma) gene rearrangement by molecular analysis, so that the diagnosis was finally corrected as NK/T-cell lymphoma and an allogeneic stem cell transplantation was successfully performed. In conclusion, this unusual case highlights the significance of MICM combined techniques for the diagnosis of lymphoma, as well as an unusual presentation of a rare disease and the successful treatment.
