Abstract
We report here a case of nasal natural killer/T-cell lymphoma with metastasization into the pancreas. A 43-year-old Chinese female patient presented with right nasal obstruction and purulent rhinorrhea that lasted for the past half year and worsened gradually despite antibiotic medical treatment. Physical examination revealed a mass in the right nasal cavity and an enlarged lymph node in the right submandibular region. A PET/CT scan and immunostaining of the resectate led to a diagnosis of nasal natural killer/T-cell lymphoma, clinical stage IIE, and the International Prognostic Index score of 1. The patient received radiotherapy followed by four cycles of the CHOP chemotherapy. A complete remission was achieved, and the patient was disease-free for 9 months. On a subsequent follow-up, abdominal ultrasound scan, enhanced abdominal CT scan, and ultrasound-guided fine-needle aspiration biopsy revealed pancreatic metastasis secondary to nasal lymphoma. Radiotherapy (40 Gy) to the whole pancreas was done, followed by two courses of the SMILE regime chemotherapy, leading to a complete remission. At the moment, the patient is undergoing subsequent chemotherapy.

Abstract
Peripheral-type natural killer (NK)- or T-cell lymphomas are rare disorders characterized with clonal proliferation of mature lymphocytes. They have been linked to chronic and active Epstein-Barr virus infection (CAEBV), which itself is not defined as a malignant hematological disorder. The authors present a patient with T/NK-cell lymphoma involving skin, kidneys, spleen, pancreas, and meninges. She was remarkable for having the mosaic feature of more than one type of extranodal T/NK-cell lymphoma. She also had mixed findings of CAEBV that might have been attributed both to hypersensitivity to mosquito bites and to hemophagocytic lymphohistiocytosis.

Abstract
Natural killer (NK) cells are lymphocytes that have some phenotypic and functional similarities to cytotoxic T cells but do not express the T-cell receptor complex. NK-cell malignancies may be localized or disseminated at initial examination, and most behave aggressively. The variable presentation of NK-cell lymphomas and leukemias suggests that they represent a spectrum of disease, with Epstein-Barr virus (EBV) implicated in the pathogenesis of most cases. Using cases presented in Session 10 of the 2005 Society for Hematopathology/European Association for Haematopathology Workshop on T-cell and NK-cell malignancies, we discuss outstanding issues in the classification and diagnosis of NK-cell malignancies. These difficulties are related to unusual sites of manifestation, atypical immunophenotypic features, and EBV+ T-cell tumors that resemble classical extranodal NK/T-cell lymphoma, nasal-type (EN-NK/T-NT). Although some of these cases can be grouped into ENNK/T-NT, classification of tumors that have atypical or discordant features will remain controversial, particularly when EBV is absent.

Abstract
OBJECTIVES/HYPOTHESIS To explain the processes that lead to the development of tumors in the maxillary and sphenoid sinuses. STUDY DESIGN A 32-year review of the world's literature on neoplasms of these two sinuses and a randomized case-controlled study comparing the normal mucosal architecture of the maxillary to the sphenoid sinus. METHODS Analysis of a 32-year world literature review reporting series of cases of maxillary and sphenoid sinus tumors. Tumors were classified by histological type and separated into subgroups if an individual incidence rate was reported. Histomorphometry of normal maxillary and sphenoid sinus mucosa was performed in 14 randomly selected patients (10 sphenoid and 4 maxillary specimens). Specimens were fixed in 10% formalin, embedded in paraffin, and stained with periodic acid-Schiff (PAS) and hematoxylin. Histomorphometric analysis was performed with a Zeiss Axioscope light microscope (Carl Zeiss Inc., Thornwood, NY) mounted with a Hamamatsu (Hamamatsu Photonics, Tokyo, Japan) color-chilled 3 charge coupled device digital camera. The images were captured on a 17-inch Sony (Sony Corp., Tokyo, Japan) multiscan monitor and analyzed with a Samba 4000 Image Analysis Program (Samba Corp., Los Angeles, CA). Five random areas were selected from strips of epithelium removed from each sinus, and goblet and basal cell measurements were made at magnifications x 100 and x 400. RESULTS The literature review revealed that the number and variety of tumors in the maxillary sinus are much greater than those in the sphenoid. The incidence of metastatic lesions to each sinus is approximately equal. No recognized pattern of spread from any particular organ system could be determined. On histomorphometric study there were no statistically significant differences between the sinuses in the concentration of goblet cells, basal cells, or seromucinous glands. CONCLUSIONS Factors involved in the pathogenesis of tumors of the maxillary and sphenoid sinuses include differences in nasal physiology, embryology, morphology, and topography. There are no significant histological differences in the epithelium and submucous glands between the two sinuses to explain the dissimilar formation of neoplasms.

Abstract
Primary neoplasms of the pancreas are most often adenocarcinoma. Non-Hodgkin's lymphoma (NHL) involving the pancreas is less common but well documented; the pancreas as the primary site of NHL is rare. The majority of patients with pancreatic cancer, whether it is adenocarcinoma or lymphoma, present with a mass in the head of the gland. Pancreatic lymphoma is often described as a large homogeneous mass with extra-pancreatic extension, with or without associated lymphadenopathy. Less common presentations are masses in the body or tail, or more rarely diffuse involvement of the pancreas. We present a case of diffuse pancreatic lymphoma with extra-pancreatic dissemination to the spleen and lymph nodes, and review the literature on pancreatic lymphoma. Because the definition of pancreatic lymphoma and primary pancreatic lymphoma varies, we also propose a nomenclature system to make future studies of pancreatic lymphoma more comparable.

Abstract
The majority of nasal lymphomas are of the natural killer (NK)/T cell lineage. We analyzed 33 specimens of nasal lymphoma from Japanese patients for Epstein-Barr virus (EBV). Phenotypic and genetic analyses showed 28 cases with NK/T cell type and 5 cases with B cell type. All NK/T lymphomas were of pleomorphic cell type except 2 large cell (centroblastoid) and one lymphoblastic lymphoma. All cases with nasal B cell lymphoma were of large (centroblastoid) cell type. EBV was detected in all cases of NK/T cell type with the exception of one lymphoblastic case, and was monoclonally integrated in all cases examined (14/14 cases). All but one case had subtype A of EBV infection with 30-base paired deleted LMP-1 gene. One case of B cell lymphoma showed the presence of EBV infection with subtype A and deletion of LMP-1. Our results indicate that the majority of nasal lymphomas in Japanese patients are of the nasal NK/T cell type, have pleomorphic morphology, a high prevalence of EBV with a monoclonal integration, subtype A and deleted LMP-1 gene. In contrast, nasal B cell lymphoma showed monomorphic appearance and rare EBV infection.

Abstract
Natural killer (NK) cell lymphoma is a mass-forming neoplasm of putative NK cell lineage that typically appears in extranodal locations and has the following immunophenotype: CD2 positive, surface CD3 negative, cytoplasmic CD3 positive, and CD56 positive. We report a case of small-intestinal NK cell lymphoma that was originally diagnosed as an enteropathy-associated T-cell lymphoma based on paraffin immunohistochemistry. However, subsequent flow cytometric immunophenotyping of paracentesis fluid resulted in the correct diagnosis. We describe the case to illustrate the usefulness of this technique, which has not previously been described in such a case.

Abstract
The authors report four cases of sinonasal lymphomas with immunophenotypic (four cases) and genotypic (three cases) studies. These lymphomas are frequent in Oriental countries, but unusual in Western populations, particularly in France. Although they have been originally considered as T-cell lymphomas, their origin remains unclear, and several authors have recently suggested that they are a natural killer (NK)-cell proliferation. The tumor cells of the four cases reported here showed characteristics of NK cells. On cryostat sections, they were CD3 negative, but CD2 and CD56 positive. The cytoplasm of the tumor cells exhibited azurophilic granulations. Using polymerase chain reaction (PCR), no clonal rearrangement of the T-cell receptor gamma gene was present. Furthermore, clinically, two presented a pharyngeal involvement, and two were also characterized by hepatosplenic involvement at the time of the diagnosis. Thus, the present cases provide additional evidence toward the NK-cell origin of these rare lymphomas. Many sinonasal lymphomas, including the present cases, are positive for Epstein-Barr virus (EBV) (LMP-1 antibody and EBER-messenger RNA probes). This may suggest an important role of EBV as a local factor in their pathogenesis.

Abstract
A workshop jointly sponsored by the University of Hong Kong and the Society for Hematopathology explored the definition, differential diagnosis, and epidemiology of angiocentric lymphomas presenting in the nose and other extranodal sites. The participants concluded that nasal T/natural killer (NK) cell lymphoma is a distinct clinicopathologic entity highly associated with Epstein-Barr virus (EBV). In situ hybridization for EBV an be very valuable in early diagnosis, especially if tissue is sparse. The cytologic spectrum is broad, ranging from small or medium-sized cells to large transformed cells. Histologic progression often occurs with time. Necrosis is nearly always present, and angioinvasion by tumor cells is seen in most cases. Nasal T/NK cell lymphoma has a characteristic immunophenotype: CD2-positive, CD56-positive, but usually negative for surface CD3. Cytoplasmic CD3 can be detected in paraffin sections. Clonal T-cell receptor gene rearrangement is not found. Tumors with an identical phenotype and genotype occur in other extranodal sites, most commonly in the skin, subcutis, and gastrointestinal tract, and should be referred to as nasal-type T/NK cell lymphomas. The differential diagnosis includes lymphomatoid granulomatosis, blastic or monomorphic NK cell lymphoma/leukemia, CD56-positive peripheral T-cell lymphoma, and enteropathy-associated T-cell lymphoma.
