AbstractAbstract
[en] Inverted papilloma is an uncommon benign epitelial tumor of the nose and paranasal sinuses with high recurrence rate after surgery and may undergo malignant change. The tumor has the ability to destroy bone and to extend to the anterior and middle cranial fossa; thus, carcinoma should be considered in the differential diagnosis. A total of eight patients with histologically proven inverted papilloma was seen and its radiologic features are described and compared to those of the literature. (author)

AbstractAbstract
[en] Natural killer/T-cell (NK/T-cell) lymphoma is a rare condition, which presents as necrotic, granulomatous lesions involving the nose and the upper respiratory tract. The condition usually has an aggressive clinical course. The predominant subtype of NK/T-cell lymphoma noted in Asian population is the nasal type. We describe a case of biopsy-proven NK/T-cell lymphoma with bilateral adrenal involvement. Adrenal involvement by lymphoma is usually of B-cell type and occurs in disseminated disease and often unilateral. Bilateral adrenal involvement by T-cell lymphoma is extremely rare

AbstractAbstract
[en] Esthesioneuroblastoma is an uncommon tumour of neural crest origin arising in the nasal cavity. This paper is a retrospective review of 7 patients with esthesioneuroblastoma treated at a single institution from May 1974 to July 1990. 5 patients were treated with radiation therapy alone and 2 patients were irradiated after surgical resection. No local or regional occurrence was observed in any patient at 6 months, or at 1, 3, 6, 11.5 and 12 years following treatment. One patient died of intercurrent disease 6 years after radiation therapy, 2 patients died of disease, 1 of distant metastasis at 6 months and the other patient of meningeal carcinomatosis and distant metastases 1 year after treatment. One patient is alive with distant metastases 1 year after treatment. None of the patients experienced significant complications of irradiation. High-dose irradiation (60 Gy or more) alone or in combination with resection is an effective local treatment modality for esthesioneuroblastoma. (author)

AbstractAbstract
[en] The authors evaluate 117 patients affected by paranasal sinuses carcinoma treated by radiation therapy alone or post-operative irradiation, from 1976 to 1984. Among these: 4 T1, 21 T2, 48 T3 and 44 T4; 66 cases were squamous cell carcinomas, 23 adenocarcinomas, 16 undifferentiated carcinomas and 12 adenoid cystic carcinomas. The overall 3 and 5 years actual survival rates were, respectively, 46% and 27%. The survival rates for stages T1 and T2 were 82 and 48% at 3 and 5 years; for stages T3 and T4 were 36% and 21%. According to the hystological type the survival rate varied from 50% for adenoid cystic carcinomas to 0% for undifferentiated carcinomas at 5 years. The survival rate for the group of patients treated with post-operative irradiation was 37% at 5 years, versus 10% for the group of patients treated by radiotherapy alone. Complications have been minimal. Causes of failure are discussed. In conclusion, the authors consider a multicentric study as necessary to determine the efficacy of various schedules of treatment

AbstractAbstract
[en] From 1970 to 1985, 45 patients with carcinoma of the upper nasal cavity and ethmoid sinuses were radically treated. The tumor parameters, treatment strategy, radiotherapy technique and the results of treatment of these patients are retrospectively analyzed in this study with particular reference to complete blindness as a major complication. In most cases tumor was removed by meticulous surgical dissection, and thereafter quality-controlled radiation therapy (external therapy: mean dose 65 Gy in about 7 weeks, or external therapy with brachytherapy boost: mean dose 82 Gy in about 10 weeks) was used for this group of patients. The results show 68 per cent recurrence-free survival at 5 tears, adjusted for intercurrent deaths. Complications of treatment were seen in seven patients (16 per cent) who developed eye damage with some loss of visual acuity, none however leading per se to complete blindness. It may be concluded that blindness may be avoided to a major extent while treating carcinomas in the nose-ethmoid areas without compromising loco-regional control. (author). 13 refs.; 3 figs.; 6 tabs

AbstractAbstract
[en] The author observed a rare case of radicular dentin dysplasia associated with enamel hypoplasia in a 11-year-old boy with a complaint of gum boil formation. 1. Clinically, yellowish-brown colored teeth with severe attrition and several gum boils were observed. 2. Radiographically, obliteration of pulp chamber and root canal, multiple periapical radiolucencies without obvious cause and blunt roots were observed. 3. Systemically, scalp hair and eyebrows were loose and short. And saddle nose could be also seen.

AbstractAbstract
[en] Normally, there are three pairs of nasal turbinates in the nasal cavity. Coronal computed tomographies of 253 cases of sinusitis were examined for the presence of additional turbinates and bilateral secondary middle turbinates were detected in two cases. Also, we describe another accessory turbinate, 'bifid inferior turbinate', in one of these cases. Existence of these accessory turbinates may occur during embryologic development of lateral nasal wall
