This case report is a 65 year old woman from Kerman. Her main complian is NASAL obstruction and recurrent NASAL bleeding from .five months ago. In clinical examination there was a large tumor in left NASAL CAVITY. CT scaning revealed a large tumor in left NASAL CAVITY and maxillary sinuse. The tumor is resected compeletely with negative safe margine by radical Caldwell- luc approach. The origin of tumor was from inferior turbinate. The diagnosis is mesenchymal sarcoma. These sarcomata are very rare in NASAL CAVITY.

Introduction: Malignant fibrous histiocytoma is rare in the head and neck and it accounts for 1-3% of all cases. Case report: We report a case of malignant fibrous histiocytoma of the NASAL CAVITY in a 64-yearold woman. The patient referred with NASAL obstruction and underwent wide surgical resection with negative margin. He is well with no evidence of disease for 36 month after surgery. The epidemiological aspects, histological diagnosis, treatment and outcome of this tumor are discussed.

Histiocytic sarcoma is a rare hematopoietic malignancy that originates from histiocytes, and may involve lymph nodes and extranodal sites such as the spleen, head and neck, skeleton, liver, breast, bone marrow, mediastinum, pancreas, skin, lung, kidney, central nervous system, testis, gastrointestinal tract, and uterus. The involvement of the NASAL CAVITY is considered extremely rare. The prognosis is poor, even with chemotherapy, and the survival time is usually two years. We report the case of a 16-year-old-male with primary histiocytic sarcoma of the NASAL CAVITY. The diagnosis was based on classical histopathology and immunohistochemical findings. This malignancy has not shown consistent satisfactory responses to chemotherapy regimens.

Supernumerary tooth in the NASAL CAVITY is rare especially if teeth numbers and occlusion are normal. In the present article we report a case of a 33-year old woman with Supernumerary tooth in the NASAL CAVITY. Supernumerary tooth was removed completely through an oral CAVITY incision.

Introduction: Diagnosis of orbital foreign body (FB) penetration is usually obvious when part of the FB is still attached at the entry wound (1). However, the depth and course of the FB in this case was not visible. Case Report: A 5-year old female presented with a pencil penetrating the left orbit. A computed tomography (CT) scan showed that the pencil penetrated the left orbit (extraseptal) through the lacrimal bone to the left NASAL CAVITY, then perforated the NASAL septum, crossing the right NASAL CAVITY. Finally, the pencil penetrated the lamina paperatea to the right orbit and stopped near the right optic nerve. The pencil was gently removed under general anesthesia with close observation of the eyes. Conclusion: A case of a pencil penetrating both orbits and NASAL cavities was reported, and the pencil was safely removed. This draws attention to the possible penetration power of a pencil, with the possibility of injury to the orbit and optic nerve on the opposite side of the penetration. It also demonstrates the feasibility of safe removal.

Papillary thyroid carcinoma (PTC) is one of the most commonly diagnosed types of differentiated carcinoma of the thyroid. It is stated that lung is the most common site of metastasis followed by bone. The incidence of paraNASAL sinus (PNS) metastasis is fairly uncommon in case of thyroid carcinoma. To the best of our knowledge, no case of metastatic PTC to NASAL CAVITY has been reported. In this case report, we present the first case of papillary carcinoma of the thyroid with NASAL CAVITY metastases in a 55-yearold female. The patient underwent surgical treatment and the mass was completely removed and sent for pathology. The pathology report revealed that it was metastatic papillary cell carcinoma. Surgical approach is usually difficult in view of the cosmetic and functional concerns, but may be considered in selected cases. As described herein, this rare type of metastasis was successfully removed and the patient was symptoms free after 1-year follow-up.

Introduction: Giant cell reparative granuloma (GCRG) is a rare benign fibrous-osseous neoplasm that mostly involves maxilla and mandible. Only a few cases of GCRG in the NASAL CAVITY have been reported so far.Case Report: A 37-year-old man was referred to the otolaryngology clinic with the symptoms of leftsided NASAL obstruction and bloody discharge since 3 years ago and proptosis since 3 months ago. CTscan and MRI showed a heterogeneous mass with fluid-fluid level that had caused severe bony destruction. Biopsy confirmed the diagnosis of GCRG.Conclusion: Although GCRG is rare, its clinical and radiologic characteristics should be studied. This lesion should be considered in differential diagnosis when clinical data, CT-scan and MRI findings show a fibrous-osseous lesion in the NASAL CAVITY.

Background: Chronic sinusitis is defined as a symptomatic inflammation of the paraNASAL sinuses for at least 12 weeks. Many risk factors such as genetic malformations, allergic rhinitis, gastro esophageal reflux, exposure to cigarette smoke and anatomical variations play a role in chronic sinusitis. In numerous studies NASAL CAVITY anatomical variations are introduced as one of the most important risk factors for chronic sinusitis.Objective: The aim of this study was to determine the association between the anatomical variations in paraNASAL cavities and chronic sinusitis.Methods: This cross-sectional study was performed on 218 suspected participants (over 18 years old) to chronic sinusitis who were referred to the infectious diseases clinic of Bu-Ali Sina Hospital, Qazvin from 2015-2016. According to the positive or negative confirmation of sinusitis in the CT scan, patients allocated into two groups and the prevalence of underlying characteristics and anatomical variations were compared.Findings: Sinusitis was confirmed by CT scan in 103 (47.2%) participants. There was significant statistical correlation between sinusitis and closed osteomeatal complex and concha bollosa (P=0.001 and 0.01 respectively), but the correlation between sinusitis and septal deviation, paradoxical curvature of the middle turbinate, agger nasi and haller cells was not statistically significant.Conclusion: A significant statistical correlation was observed between chronic sinusitis and the presence of some anatomical variations of the NASAL cavities such as closed osteomeatal complex and agger nasi cells. Alterations in sinus drainage and ventilation dysfunction may considered to play a role in this correlation.

Background and Purpose: Fungus Ball (FB) is a non-invasive fungal infection caused mainly by Aspergillus species. It can occur after root canal treatments are applied to the teeth adjacent to the maxillary sinus. These balls are commonly seen in the paraNASAL sinuses and rarely observed in the NASAL CAVITY. This report attempted in to highlight such a rare case of fungal infection which requires accurate observation. Moreover, it highlights the importance of careful microbiological and histopathological examinations that were combined with imaging and can lead to a definitive diagnosis. Case report: Herein, we report a rare case of a FB found in the vicinity of the NASAL CAVITY of a 73-year-old male patient. Microbiological examination supported by radiographic and histopathological results indicated that the FB is due to Aspergillus niger. Excised surgery was done to the FB area, and the patient was referred to the post-operation room with the proper recommendations. After the wound healed, the total denture was performed as requested by the patient, and his overall oral health was improved. Conclusion: In this article, we report the first case of a rare FB in the vicinity of the NASAL CAVITY of a 73-year-old male patient. The appropriate investigation is an essential step in the diagnostic process for these infections and requires effective communication and collaboration.
