Advanced adenoid cystic carcinoma of maxillary sinus: Rare case report and review of literature

IntroductionMaxillary sinus adenoid cystic carcinoma (MSACC) is a rare malignancy with a propensity for distant metastasisCase presentationWe report a case of a 55 years-old male who was admitted to our department with a complaint of right nasal obstruction and anosmia. Clinical examination, radiological investigations and histopathological examination found a mass compatible with advanced adenoid cystic carcinoma of the right maxillary sinus. Treatment consisted of radio chemotherapy.ConclusionAdenoid cystic carcinoma of the maxillary sinus may represent a serious diagnostic challenge. It should be considered in the differential diagnosis of Sino nasal tumors even if it’s rare.     

Idiopathic bilateral antral exostoses: A rare case in maxillary sinus

INTRODUCTION

Exostoses in paranasal sinuses have been reported in the otolaryngology literature, but they have not been described in the dental literature to our knowledge. The aim of this article is to describe an idiopathic and rare case of bilateral exostosis obtained by cone-beam computed tomography.

PRESENTATION OF CASE

The case shows a healthy and asymptomatic patient with a different size and form of exostoses in both maxillary sinuses.

DISCUSSION

It is difficult to clinically diagnose the antral exostosis due the asymptomatic nature of this condition, unless the approach would be through endoscope. Sometimes this condition is related with nasal irrigants, however in this case the patient asserted not having used nasal irrigation ever; thus, it is impossible to relate this kind of treatment as a principal cause.

CONCLUSION

The published data of exostoses in maxillary sinus seem to be limited in the dental literature, and this condition is important to consider in an implant treatment planning. Also, it is important to perform a follow-up of the cases in trying to find the possible causes of exostosis.     

Cyst decreased in size post maxillary sinus floor augmentation surgery in diabetic patient: A case report

IntroductionWhether mucosal cyst of maxillary sinus is contraindication for sinus floor augmentation surgery has been a controversial hot spot for years.Presentation of caseThis case aims to present the surgical procedure of sinus floor augmentation surgery with cyst (18.72 mm × 24.61 mm) in diabetic patient. And 6 months later, the cyst decreased in size. The authors elevated the sinus floor and cyst simultaneously. The surgery was carried out successfully without sinus membrane perforation and the alveolar ridge gained about 8 mm height. Six months later, the cyst decreased in size and osseointegration was observed.DiscussionInterdisciplinary cooperation is encouraged to diagnose benign mucosal cyst. The isolation between sinus lumen and the grafted sub-sinus space is important. Graft contamination or dispersion into the sinus lumen should be avoided. The integrity of the sinus membrane and use of antibiotics are very important to prevent the occurrence of postoperative sinus infectionConclusionThe authors conclude that sinus augmentation surgery could be done with mucosal cyst in diabetic patient.

Inflammatory myofibroblastic tumours of the maxillary sinus: A brief clinical report and review of the literature

Although inflammatory myofibroblastic tumours (IMTs) have been accepted as a clonal neoplasm, their pathology is poorly understood due to variable presentation. There is no identifiable cause and they are usually observed as tumour growth combined with inflammation. In the current WHO classification, IMTs are designated as intermediate malignancies. In terms of biological potential, IMTs are classified under ‘rarely metastasizing’. IMTs are rare in the maxillary sinus but, when reported, can be locally aggressive or even destructive if they invade the orbit. The authors present a brief clinical report describing a five-year-old girl with a slow-growing mass in the right maxillary sinus extending into the lacrimal sac and its management.     

Primary bronchopulmonary fibrosarcoma: Report of a case

We herein report a case of primary bronchopulmonary fibrosarcoma in a 70-year-old man. The patient was referred to our hospital for investigation of hemosputum and an abnormal shadow. On admission, chest radiograph and computed tomography scan showed a mass lesion in right S³ and an infiltrative shadow in the right upper lobe. Transbronchial biopsy specimens showed findings of malignancy, and adenocarcinoma was suspected. A right pneumonectomy was performed, and pathologic examination confirmed a diagnosis of fibrosarcoma. The patient had an uneventful recovery and no sign of recurrence has been found in the year since his operation, although strict follow-up is essential.     

Plasma cell granuloma of the maxillary sinus: a case report and literature review

BACKGROUND: Plasma cell granulomas are rare and heterogeneous tumor-like lesions of mixed inflammatory cell infiltrates of unknown etiology. Although they have the potential to occur in sites throughout the body, their occurrence in the paranasal sinuses and nasal cavity is uncommon and often associated with unique clinical characteristics and natural history. METHODS: We present a case of an aggressive plasma cell granuloma of the maxillary sinus and a review of the literature (28 cases). RESULTS: The patient was treated with definitive radiotherapy (45 Gy in 25 fractions) and experienced a local recurrence 2 years later. The lesion initially responded to corticosteroids and then progressed. Resection was performed and was followed by another recurrence. The patient was treated with radiosurgery and is disease free 8 years after initial treatment. CONCLUSIONS: Review of the literature indicates that the optimal first line of treatment is high-dose corticosteroids. Surgery is indicated if the lesion fails to respond. Radiotherapy is indicated if complete resection is not feasible.

Bilateral dentigerous cysts and ectopic teeth in the maxillary sinuses: A case report and literature review

IntroductionDentigerous cysts are the second most common form of benign odontogenic cysts. These cysts are commonly single lesions. Bilateral and multiple dentigerous cysts are very rare.Case presentationThis article presents a rare case report of bilateral dentigerous cysts associated with two ectopic teeth located atypically in the maxillary sinuses in a 19-year-old male manifesting as bilateral upper jaw pain, post-nasal discharge and recurrent sinusitis which was managed via the endonasal endoscopic approach by enucleation of the cysts and teeth removal.ConclusionThis paper presented our experience in the management of a rare case of bilateral dentigerous cysts associated with ectopic teeth in the maxillary sinuses. Ct scan of the paranasal sinuses confirmed the diagnosis and the endonasal endoscopic approach is superior to the external approaches in preserving physiological function in managing these patients.     

Osteoma of maxillary sinus: a case report.

Craniofacial osteomas may be located either superficially or intraosseously on any bone of the cranium or face or within a paranasal sinus. Osteomas within the paranasal sinus account for 0.01% to 0.43% of patients; of these, up to 80% occur in the frontal sinus. An osteoma of maxillary sinus is extremely rare. We describe a rare case of osteoma of a 56-year-old Asian woman in the maxillary sinus.     

Response of cavernous sinus hemangioma to radiotherapy: a case report

The author reports a case of a histologically proven cavernous hemangioma of the cavernous sinus and middle fossa, which was treated by radiotherapy. This very rare lesion represents a formidable challenge to the neurosurgeon and its excision has been associated with a considerable mortality rate. The significant reduction in the size of tumor of our patient after radiotherapy and the corresponding improvement in her clinical condition provide further evidence in support of the use of radiotherapy as the first line treatment modality after the histological confirmation of a cavernous sinus hemangioma. Surgery should be reserved for tumors that fail to respond to radiotherapy or recur after an initial good response to radiotherapy.     

Conservative treatment of a traumatic direct low-flow carotid-cavernous sinus fistula: A case report

Summary A case of a 17-year-old boy presenting with a traumatic carotid-cavernous sinus fistula (CCSF), associated with an intracavernous pseudo-aneurysm, is reported. On angiography, the CCSF proved to be a direct and low-flow shunt. Conservative management was chosen and definitive closure of the fistula was obtained in two months by daily self-compression of the common carotid artery.     

Malignant mucosal melanoma of the right maxillary sinus: a case report.

The case of a 74-year-old female is reported. The patient was under long-term review for melanosis affecting the mucosa of the upper right alveolar ridge. The patient developed a primary mucosal melanoma at the site 5 years later and underwent a right maxillectomy and a modified right neck dissection to level 5 nodes. The defect was covered with an obturator; the patient is at present clinically disease free. Mucosal melanomas account for 1% of all melanomas reported. This is a more aggressive tumor than the cutaneous melanoma, which is reflected in the low survival rate of 3 years (approximately 50%). Of the patients that survive to 5 years, 50% will have residual disease. Surgical procedure is indicated to reduce the tumor burden, but difficulties associated with gaining complete resection mean that both local and distant metastasis is problematic. More radical resection and adjunctive radiotherapy have not been shown to increase survival times.
