1/939. Nasal and nasal-type natural killer/T-cell lymphoma.

    Nasal and nasal-type natural killer (NK)/T-cell lymphomas follow an aggressive course and have a poor prognosis. Recent pathologic studies suggest that the disease is a malignant proliferation of NK cells, which often express CD56. An association with the Epstein-Barr virus has also been reported. skin involvement occurred in each of the 3 patients studied. radiation therapy provided some benefit to the patients in the early stages. Conventional chemotherapies were not effective. To overcome this multiple-drug resistance of the tumor cells, cyclosporine and high-dose chemotherapy was combined with peripheral-blood stem-cell transplantation. The average life span from the onset of the disease for our patients was 9.6 months. Further improvement in the management of nasal and nasal-type NK/T-cell lymphomas is necessary.

2/939. Nasal reconstruction in children: a review of 29 patients.

    Acquired large nasal defects are much more common in adulthood than in childhood because of the frequency of skin tumors after a certain age. However, from their experience in treating a number of children with sequelae of noma and burns, the authors have collected a series of 17 total and 12 partial nasal reconstructions in children aged 1 to 15 years. After reviewing the various methods used for recreating the lining, the support, and the skin cover in the whole series, three cases are reported in detail. A 1-year-old patient received a tempororetroauricular flap after total amputation of the nose and was observed for 17 years. Another patient, who was burned as a baby, underwent reconstruction at age 10 with a deltopectoral flap and was observed for 7 years. The third patient underwent total nose reconstruction at age 12 with an Indian forehead flap. From their experience, the authors conclude that, for psychosocial reasons, nasal reconstruction should be started early, despite possible reoperation at a later age. The best results are certainly obtained at the end of growth or at least after the age of 12. Adjacent bone or soft tissue defects further enhance the difficult challenge of restoring a satisfactory aesthetic appearance in these children.

3/939. craniopharyngioma invading the nasal and paranasal spaces, and presenting as nasal obstruction.

    A case of craniopharyngioma invading the nasal and paranasal sinuses and presenting as nasal obstruction is reported. Imaging showed a destructive mass of the skull base with involvement of the nose and paranasal sinuses. In the excised mass mitoses were frequent and the proliferation index was high. Invasion of the nasopharynx and presentation as a nasopharyngeal mass is uncommon for a craniopharyngioma.

4/939. Metastatic testicular teratoma of the nasal cavity: a rare cause of severe intractable epistaxis.

    Malignant neoplasms of the nasal cavity and paranasal sinuses are uncommon. choriocarcinoma is a highly malignant germ cell tumour occurring in the reproductive organs. Metastasis may be principally by the lymphatic route as in other germ cell tumours but choriocarcinoma is also known to spread haematogenously. We present a rare case of metastatic choriocarcinoma to the nasal cavity from testicular teratoma presenting with intractable epistaxis in a 32-year-old Caucasian male, who ultimately succumbed to this disease.

5/939. Nasal and nasal-type T/NK-cell lymphoma with cutaneous involvement.

    Natural killer (NK) cells are a third lymphocyte lineage, in addition to B- and T-cells, that mediate cytotoxicity without prior sensitization. NK cells also have phenotypic and genotypic characteristics; they express the NK-related antigen CD56 and T-cell markers such as CD2 and CD3 epsilon, but their T-cell receptor (TCR) locus is not rearranged. Non-Hodgkin's lymphomas are divided into B- and T-cell neoplasms and NK-cell lymphomas. We describe 2 Japanese patients with nasal and nasal-type T/NK-cell lymphoma in which the skin, nasal/nasopharyngeal region, bone marrow, and lymph node were the sites of involvement. The clinical and histopathologic findings were recorded. In addition, immunophenotyping, TCR gene rearrangement, and the existence of Epstein-Barr virus (EBV) dna by polymerase chain reaction amplification were determined. Clinically, the cutaneous eruptions were purplish, hard, multiple nodules. Histologically, angiocentric proliferation of small-to medium-sized, pleomorphic, lymphoid cells were observed. They revealed hand-mirror-shaped lymphocytes with azurophilic granules with the use of Giemsa staining by touch smear. These lymphocytes were found to be positive to immunophenotyping for CD2 (Leu5b), CD3 epsilon (DAKO), CD4 (Leu3a), and CD56 (Leu 19). No clonal rearrangement of TCR-beta, -gamma, and -delta genes and immunoglobulin gene markers were found, and no positive results of identification of EBV dna were shown. The patients underwent cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy with complete remission; however, both had recurrence of disease. Because NK-cell lymphomas express some T-cell markers, they may be mistakenly diagnosed as peripheral T-cell lymphomas if they are not investigated for the NK-cell-specific marker, CD56. Therefore the importance of immunophenotypic investigations of CD56 should be stressed. Also, the importance of clinical investigation of nasal/nasopharyngeal lymphomas should be stressed when NK-cell lymphoma is diagnosed involving the skin, because NK-cell lymphomas are often associated with the nasal and nasopharyngeal region.

6/939. An unusual case of squamous cell carcinoma of the nose.

    A 49-year-old man presented with a tumoral lesion of the tip of the nose which had been manifest for 2 months. Within a few weeks, the tumour increased in size and became infiltrated. The biopsy showed a squamous cell carcinoma. Treatment consisted of a radical surgical excision.

7/939. Transnasal endoscopic repair of congenital defects of the skull base in children.

    OBJECTIVE: To examine imaging findings and methods of endoscopic treatment of congenital skull base defects in children. DESIGN: Retrospective study and case series. SETTING: Academic tertiary care center. patients: Four patients (aged 12 and 14 months and 8 and 13 years) were included from 1995 to 1997. Three presented with a nasal glioma, which was recurrent in 1 case. The fourth patient presented with bacterial meningitis due to a spontaneous cerebrospinal fluid leak. Computed tomography and magnetic resonance imaging were used to locate the defect of the skull base. INTERVENTION: Transnasal endoscopic resection of the glioma or the meningocele, with immediate repair of the skull base defects using free mucosal flaps and/or pediculized mucosal flaps and/or conchal cartilage together with fibrin glue and nasal packing during a 3-week period. RESULTS: None of the 4 patients has experienced recurrent cerebrospinal fluid leaks or postoperative meningitis. CONCLUSIONS: The transnasal endoscopic repair of congenital meningoceles is a reliable technique in select pediatric patients. Computed tomography and magnetic resonance imaging provide information that can be used to help the surgical procedure.

8/939. Huge hamartoma with inverted papilloma in the nasal cavity.

    We report clinical experience in managing a 46-year-old Japanese man with long-standing nasal obstruction resulting from a huge left nasal mass. Computed tomography, magnetic resonance imaging and biopsy were used to make a provisional diagnosis of inverted papilloma. The mass was resected via a frontal approach combined with rhinotomy. Histopathologic examination of the resected specimen was consistent with a hamartoma that included an inverted papilloma on a portion of its surface. In addition to being rare tumors in the nasal cavity, we believe that our patient's tumor the largest nasal hamartoma ever reported.

9/939. Heterotopic nasopharyngeal brain tissue associated with cleft palate.

    OBJECTIVE: The occurrence of extracranial brain tissue is rare. Most of the literature describes cases in which it is located around the nose and throat and has been classified as nasal glioma. Even more unusual is heterotopic brain tissue in the nasopharynx. We were able to find only 17 previously reported cases. Of these 17 cases, 6 had heterotopic brain tissue located in a cleft palate. This report comments on the identification and treatment of heterotopic brain tissue associated with cleft palate without connection to the central nervous system. Our case subject is a 10-month-old girl diagnosed with heterotopic nasophranygeal brain tissue associated with cleft palate. RESULTS: Excision and palatoplasty were performed conjunctively with excellent results. CONCLUSIONS: Simultaneous excision of heterotopic nasopharyngeal brain tissue and palatoplasty of the cleft palate is an excellent option for treatment of these cases.

10/939. Primary splenic tuberculosis in a patient with nasal angiocentric lymphoma: mimicking metastatic tumor on abdominal CT.

    Tuberculosis may be difficult to diagnose when it presents in an uncommon extrapulmonary site. The authors report a case of splenic tuberculosis mimicking metastatic tumor on computed tomography in a 60-year-old woman who had been treated with combination chemotherapy for nasal angiocentric lymphoma. Diagnostic splenectomy revealed multiple necrotic masses in the spleen, which were consistent with caseating granulomas microscopically. diagnosis was confirmed by positive cultures in Lowenstein medium, which grew typical mycobacterium tuberculosis organisms. Following splenectomy, the patient was also treated with a triple-drug antituberculosis regimen with no recurrence of her symptoms.
