Abstract
BACKGROUND/AIMS To describe the clinical features, imaging, histologic spectrum, treatment and prognosis of patients with malignant orbital lymphoproliferative disorders extending from the paranasal sinuses. METHODS Patients were culled from the University of British Columbia Orbit Clinic (1977-2004) and their clinical charts, imaging and pathology specimens reviewed. RESULTS The study included 6 patients with non-Hodgkin's lymphoma (NHL) and 5 multiple myeloma (MM). Orbital symptoms at presentation were periorbital swelling, diplopia, proptosis and pain. Major clinical findings were globe displacement, abnormal ocular movements, periorbital fullness, fifth nerve hypoesthesia and inflammatory signs. Imaging showed a soft tissue mass in one or more sinuses invading the orbit. Three NHL patients were still alive at last follow-up with one patient lost to follow-up. Two NHL patients and all MM died. CONCLUSION Presenting symptoms of malignant orbital lymphoproliferative disorders extending from the paranasal sinuses include mass effect occasionally with infiltrative and inflammatory characteristics accompanied by symptoms of sinus disease. On imaging, a soft tissue mass in the sinuses and orbit with bone destruction is commonly seen. Biopsy is essential for conclusive diagnosis. Treatment should be initiated promptly as local symptoms are frequently relieved and survival is possible, especially in cases of NHL.

Abstract
In the 10-year period 1987 to 1996, 24 patients were diagnosed with aggressive non-Hodgkin's lymphoma of the nasal cavities or paranasal sinuses. The disease occurred in a relatively elderly population of median age 72 years (range 42 to 96) with a male predominance (male 15; female nine). The histology on review was mostly of the large B-cell subtype (21 patients); peripheral T-cell subtype (one), anaplastic large cell of T-cell type (one) and T/natural killer cell nasal lymphoma (one). The disease was localized in 20 patients (Stage IEA). The overall survival at 5 years was 40% (95% confidence interval (CI) 19-61); at 10 years it was 33% (95% CI 12-54). The cause-specific survival (excluding deaths from causes other than lymphoma) at 5 years and 10 years was 62% (95% CI 39-86).

Abstract
Isolated primary non-Hodgkin's lymphoma of the frontal sinus is rare. We describe the case of a middle-aged man who came to us with signs of orbital cellulitis complicating an acute infected frontal mucocele. His condition was initially controlled with medical therapy and subsequent endoscopic sinus surgery, but his symptoms eventually returned. We were able to diagnose the lymphoma only by approaching the sinus externally to obtain a biopsy. This case highlights the importance of making a full visual inspection of the involved sinus in order to avoid missing an unexpected, albeit a rarely encountered, pathology.

Abstract
OBJECTIVES A review of the presenting features, management, and outcome of extranodal non-Hodgkin's lymphoma (NHL) of the sinonasal tract during a 10-year period in Nottingham, UK. STUDY DESIGN Twenty-four patients received a diagnosis of extranodal NHL of the nasal cavity, paranasal sinuses, or both, from 1987 to 1996. The patients' data were collected prospectively in the Nottinghamshire Lymphoma Registry. METHODS All patients' records and their histology were reviewed along with data entered into the Nottinghamshire Lymphoma Registry, noting the patient's age, sex, presenting symptoms and signs, staging, computed tomography findings, histology, treatment, complications, and outcome. RESULTS The 24 patients with extranodal NHL of the sinonasal tract represent 1.63% of the 1,457 patients with NHL seen in the 10-year period of this study in Nottinghamshire. The median age was 72 years (range, 42-96 y), with a male dominance (male-to-female ratio: 15:9). Most patients presented with nonspecific nasal symptoms such as nasal obstruction and epistaxis. Only one patient had a relapse involving the central nervous system after treatment. All the histology was reviewed and showed a predominance of large B-cell subtype (21 patients). The overall 5-year survival was 40% (95% CI, 19%-61%) and 33% for 10-year (95% CI, 12%-54%). The cause-specific survival at 5 years and 10 years was 62% (95% CI, 39%-86%). CONCLUSIONS A high degree of suspicion and appropriate use of computed tomography scans and surgical biopsy are the keys to the management of NHL.

Abstract
Sinonasal lymphomas represent a distinct subset of extranodal head and neck lymphomas. While sinonasal lymphomas are relatively rare in Western countries, in Asian populations they are the second most frequent group of extranodal lymphomas, after gastrointestinal lymphomas. With advances in immunohistochemistry, these lymphomas have been separated into B-cell, T-cell, and most recently into natural killer (NK) cell phenotypes. The B-cell phenotype is typically located in the paranasal sinuses and has a slight predominance in Western countries. The T/NK-cell phenotype is the most common in Asian and South American countries. These tumors are typically located in the nasal cavity and have an aggressive, angioinvasive growth pattern that often results in necrosis and bony erosion. Thus, sinonasal lymphomas have been included in the past with other destructive malignant and benign lesions under the descriptive and nonspecific name lethal midline granuloma. Patients are classically in the sixth to eighth decades, with a 2:1 male-to-female ratio. The prognosis is generally better than that of nodal-based lymphomas of similar histologic grade. Treatment is a combination of local irradiation and chemotherapy with an anthracycline-based regimen.

Abstract
A high prevalence of nasal lymphoma expressing a T- or natural killer (NK)-cell phenotype (NTCL) with frequent association of Epstein-Barr virus (EBV) has been indicated in Asians. To characterize NTCL among the Japanese, the clinicopathologic features of 32 cases were evaluated and the cases were also analyzed for EBV-RNA using an ISH method. Morphologically, 31 cases were identified by atypical pleomorphic lymphoid infiltrates with polymorphous, angicentric, and necrotic features. Their lymphoma cells ranged in size from small to large and were mixed in varying proportion from case to case. The other one case showed a monomorphic 'blastic' appearance. EBV-encoded small RNA (EBER) was detected in the neoplastic cells of 27 of the 32 cases examined. In the five EBV-negative cases, one was the 'blastic' type. Clonal T-cell receptor gene rearrangement was detected in none of seven cases examined. The patients had a median follow-up of 9 months (range, 1 month to 14 years and 11 months). The Kaplan-Meier estimate of overall survival was 49% at 5 years, correlating with clinical stage. These data support the concept that most cases of NTCL are identified as tumors with T/NK-cell characteristics and EBV association, distinctly different from other peripheral T-cell lymphomas. Furthermore, the one case of an EBV-negative 'blastic' variant appears not to fit well into the pleomorphic category but more closely resembles the pathologic features of extranasal angiocentric lymphoma with lymphoblastoid appearance. This study also showed no clear difference in clinical aspects other than the original site or in prognosis, between NTCL and extranasal angiocentric lymphomas despite the higher incidence of EBV association and the tendency for that peculiar anatomical site to be restricted to the former group.

Abstract
BACKGROUND Non-Hodgkin's lymphomas (NHLs) of the sinonasal tract are uncommon neoplasms that can be morphologically difficult to distinguish from destructive nonneoplastic processes or other malignant neoplasms in this site. METHODS From the files of the Otolaryngic Tumor Registry-Armed Forces Institute of Pathology from 1965 to 1992, 120 cases of NHL involving the sinonasal tract were selected for which clinical records and paraffin-embedded tissue blocks were available. The histologic features and immunophenotypic findings of each patient were examined, and follow-up data were obtained for 66 (55%). RESULTS The ratio of males to females was 1.35:1, and the ages ranged from 3 to 94 years (median, 59 years). Sixty percent of the cases of NHL occurred in the patients' sixth to eighth decades of life. Clinical presentations varied according to histologic type. The low grade lymphomas presented with a nasal cavity or paranasal sinus mass associated with obstructive symptoms. The high grade lymphomas were more likely to present with aggressive signs and symptoms including nonhealing ulcer, cranial nerve manifestations, facial swelling, epistaxis, or pain. Of note, the high grade B-cell lymphomas tended to present with soft tissue or osseous destruction, particularly of the orbit with associated proptosis, whereas the T-cell lymphomas were associated with nasal septal perforation and/or destruction. Sites of disease included the nasal cavity, one or more paranasal sinuses, or multiple regions within the sinonasal tract. Of patients who received adequate follow-up, nodal and extranodal dissemination were identified in a limited number (n = 11). Nodal dissemination occurred in cervical and axillary lymph nodes. Extranodal sites of involvement included the larynx, skin, liver, uvula, kidney, breast, lacrimal gland, testis, and prostate gland. There was a wide spectrum of morphologic types of lymphoma, classified according to the Working Formulation. Immunophenotypic analysis on paraffin embedded tissue sections of all patients demonstrated a B-cell to T-cell ratio of 1.18:1. Treatment primarily included radiotherapy and chemotherapy. Follow-up information was available for 66 (55%) patients ranging from 1 to 16 years (median, 3 years). Of these 66 patients, 24 (36.4%) died of disease, 17 (25.7%) are alive without disease, 13 (19.7%) are alive with disease, and 12 (18.2%) are dead of unrelated or unknown causes. CONCLUSIONS Non-Hodgkin's lymphomas of the sinonasal tract are heterogeneous diseases that can be clinically aggressive. The frequency of these lymphomas in the United States cannot be estimated accurately because all of our cases were of histologic slides submitted for consultations. There appears, however, to be a slight B-cell predominance in this population that previously has been observed, unlike in South America and Asia where the majority of cases have a T-cell phenotype.

Abstract
Paranasal and nasal neoplasms often elude early diagnosis in the pediatric population. This report examines 3 cases of nasal and paranasal sinus lymphomas out of 29 lymphomas and lymphoproliferative disorders seen from 1983 to 1990. Diagnostic delays are common. The development of orbital signs and symptoms often leads to diagnosis. Computed tomography and magnetic resonance imaging are important in delineating the extent of disease and allow appropriate staging. Transnasal biopsy yields the definitive diagnosis, with low associated morbidity. Aggressive chemotherapy and irradiation prolongs survival; with this regimen all of our patients have remained alive, although 1 has residual disease. B-cell lymphomas are more common than T-cell varieties in children. One patient demonstrated B-cell immunodeficiency and preleukemia prior to developing primary paranasal sinus non-Hodgkin's lymphoma; this case reiterates the systemic nature of lymphoma, Key differences between children and adults in the manifestations of nasal and sinus lymphomas are emphasized.

Abstract
From 1975 through 1988, nine patients with locally confined nasal non-Hodgkin's lymphoma (NHL) were treated with radiation therapy in the Department of Radiology, Chiba University Hospital. Immunohistochemical study disclosed that all NHL's have T-lineage. Additionally, unique histological pictures of polymorphism, angiodestruction, and necrosis were seen in most of cases. These three findings are the histological features of polymorphic reticulosis (PMR), which is the main cause of lethal midline granuloma and has recently been shown to belong to T-cell malignancy. Therefore, it is concluded that the nasal T-cell NHL and PMR are really a single disease entity. The predominance of the T-cell lymphoma in the nasal cavity as well as its histological distinctness clearly indicate that the head and neck extranodal NHL cannot be discussed together. Although the disorder was considered to be locally limited at presentation, only 3 of the 9 patients with nasal NHL could be induced into long-term remission with involved field radiotherapy. The distant extranodal spread was the primary cause of failure. Multimodality treatment using intensive chemotherapy might improve the prognosis of nasal NHL.

Abstract
Lymphoproliferative disorders are the frequent cause of indeterminate processes in the head and neck region for which otolaryngologists are often consulted by colleagues seeking a diagnosis. Because a wide spectrum of diseases may be represented, tissue diagnosis is often required. Recent advances in tissue immunotyping and DNA probes permit more precise identification and classification of these disorders. Lymphoproliferative disorders may be subdivided into five categories: Hodgkin's disease, non-Hodgkin's lymphoma, histiocytosis X, benign reactive lymphoproliferative disorders, and plasma cell neoplasms. Representative cases are presented, along with a brief discussion of each category.

Abstract
Twenty-six non-Hodgkin's malignant lymphomas (ML) of the Waldeyer's ring, the mouth and nasal cavities were studied morphologically and immunohistochemically on paraffin and frozen sections. A B-cell origin was shown in all 14 cases of Waldeyer's ring M.L., while 5 of 7 nasal and 3 of 5 buccal cases were of T-cell nature. Seventy-nine per cent of all the above ML were high-grade malignancies. Combined morphological and immunohistochemical studies of such malignant lymphomas in Western populations have been reported rarely and are rather limited. The documentation of the first nasal and buccal cases of anaplastic Ki-1 positive peripheral T-cell ML is emphasised in conjunction with the more frequent carcinomas of the same anatomical areas under consideration.

Abstract
The incidence of malignant lymphomas in the nasal cavity and paranasal sinuses was found to be 0.17% of all malignant lymphomas and 0.44% of all extranodal malignant lymphomas registered in the Kiel Lymph Node Registry from 1972 to 1987. Fifty-nine cases of malignant lymphoma presenting in the nasal cavity and paranasal sinuses were investigated with morphological and immunological methods. The median age of the patients was 64.5 years, with a female predominance (m:f = 0.87:1). In the 59 cases a marked preponderance of B-cell lymphomas was found (centroblastic n = 15, immunoblastic n = 8, Burkitt's lymphoma n = 6, Immunocytoma n = 3, centrocytic n = 1, centroblastic/centrocytic n = 1, plasmacytic n = 11); only a small number (n = 5) was of T-cell lineage (pleomorphic types). Nine further cases could not be assigned with certainty to either the T or B cell system. Angiocentricity with infiltration and destruction of vessel walls by tumour cells was demonstrated only in the T-cell lymphomas; the B-cell lymphomas, in contrast, often surrounded and compressed blood vessels with intact endothelium. No similarity to malignant lymphomas of mucosa associated lymphoid tissue, such as those in the gastrointestinal tract, was detected.

Abstract
Twenty-five patients with sinonasal lymphoma were treated mainly with irradiation. All were non-Hodgkin lymphomas of diffuse type. Twenty patients had stage IA, 2 had stage IB, 1 stage IIA, 1 stage IIIA, and 1 stage IVA disease. Relapse developed in 16 (64%) of the 25 patients, with a failure rate of 64 per cent in the stage I patients (14/22). Most patients with failures had distant spread of the disease with or without local recurrence. Only one patient had local recurrence alone at the first relapse. Histologic classification according to the new working formulation seemed to be a reliable prognostic indicator for relapse: failure rates for low, intermediate, and high grade lymphomas were 0 per cent (0/2), 46 per cent (6/13), and 100 per cent (10/10), respectively. Computed tomography was valuable for planning of radiation therapy and for follow-up.

Abstract
Extranodal lymphomas which present in the nasal cavity and/or the paranasal sinuses are rare. Thirty-eight patients with disease that was clinically limited to the head and neck (Ann Arbor Stages IE-IIE) were admitted between 1947 and 1983. Twenty-eight patients were treated with radiotherapy alone and 10 received combination chemotherapy in addition. The overall 5-year survival figure was 56%. The corresponding result for Stage IE was 67%. No patient with Stage IIE disease survived 5 years. Extent of the extranodal disease also influenced results for Stage IE patients who were treated with radiotherapy only. When the extranodal disease was staged using the American Joint Committee TNM system, the 5-year disease-free survival for T1 and T2 patients was 78% as compared with 19% for patients with T3 and T4 disease. The addition of combination chemotherapy improved results for patients with T3 and T4 lesions.

Abstract
Malignant lymphoma is primarily a disease of interest to haematologists, but it occasionally presents a problem for otorhinolaryngologists. Sinonasal lymphomas are rare and potentially radiocurable malignant neoplasms. At initial presentation, the disease is most often localized in the sinonasal region and, with rare exceptions, the dominating cytohistological type is the immunoblastic sarcoma (B-cell type), previously termed reticulum cell sarcoma. The clinical manifestations may mimic more common and benign conditions and the diagnosis may be difficult. The present paper, emphasizes the need for biopsy to be performed early and carefully even in the case of apparently benign lesions.
