Spherulocytosis of the maxillary sinus: a case report

Spherulocytosis (myospherulosis) is an unusual foreign-body reaction usually occurring in tissues exposed to petrolatum-based products. Due to its occasional localization in the maxillary sinus, it is of interest to rhinologists and maxillofacial surgeons. The pathogenesis of spherulocytosis has remained a matter of controversy. We present the case of a 40-year-old female with no previous contact to petrolatum-based substances and suffering from spherulocytosis of the maxillary sinus. The review of literature with emphasis on etiopathogenesis and factors that predispose to the development of spherulocytosis, other than exposure to petrolatum-based ointment, are discussed.     

Frontal sinus osteoma and palpebral abscess: case report

Osteomas of the paranasal sinuses are slow-growing, benign tumours most frequently found in the frontal sinus with an incidence that varies from 47% to 80% of the cases; there are often no symptoms and they are diagnosed by chance during an x-ray examination. The symptoms are usually headaches and those secondary to ocular or neurological complications. The therapy to be preferred is surgery. The authors describe a case of frontal osteoma complicated by frontal sinusitis and palpebral abscess.     

Desmoid tumor in the maxillary sinus: a case report

Desmoid tumor in the maxillary sinus is a rare condition. The present case occurred in a 37-year-old male complaining of left nasal obstruction and dull pain in the nape of the neck. The clinical picture, pathology, diagnosis and prognosis are discussed and the literature is reviewed.     

A rare aneurysmal bone cyst of the maxillary sinus: a case report

Aneurysmal bone cyst (ABC) is a non-neoplastic expansile bone lesion that is common in the long bones; only 2% occurs in the head and neck. We present a case of ABC in a 23-year-old male and describe the clinical and radiological features, histopathology and treatment. Magnetic resonance imaging (MRI) demonstrated multiple internal septations, cysts with fluid-fluid levels of varying intensity, and an intact rim of low-intensity signal completely surrounding the lesion. The tumor was removed by enucleation with resection of the lateral nasal cavity. Histopathologic diagnosis was ABC and fibrous dysplasia. We suggest that MRI is very useful for the diagnosis of ABC. ABC is thought to follow other lesions, and thus when treating ABC, it is important to determine whether any pre-existing lesion has preceded or not; in particular, if the lesion site is in the head and neck region.     

Rhabdomyosarcoma of the maxillary sinus. A case report

A rare case of adult rhabdomyosarcoma originating from the left maxillary sinus is reported. A 22-year-old Japanese woman was referred to the Department of Otolaryngology, Hiroshima University, for investigation of the primary source of a metastatic tumor in the bone marrow. An X-ray of the sinuses revealed a tumor in the left maxillary sinus with extension into the nasal cavity, ethmoidal and sphenoidal sinuses. The patient was managed with a chemotherapeutic regimen consisting of high-dose methotrexate, adriamycin, vincristine, cyclophosphamide and prednisolone. After three courses of this chemotherapy, the tumor had decreased in size by about 90 per cent, as indicated by X-rays. The remaining tumor was removed by an extended Denker's operation. Following the surgery another seven courses of chemotherapy were given and during the eight months following the operation the patient has been free from any local recurrence.     

Arteriovenous malformation of the maxillary sinus and mandible: a case report

Vascular tumors are rarely encountered in the paranasal sinuses. When they do arise there, they can be life-threatening because of the risk of bleeding. Embolization alone and in combination with surgical resection has been the mainstay of treatment. We report the case of a prepubertal girl who experienced two recurrences of arteriovenous malformation, one in the maxillary sinus and the other in the mandible. To our knowledge, this is the first report in the literature of recurrences arising in these two locations.

High-grade osteosarcoma of the maxillary sinus. A case report]

BACKGROUND: Osteosarcoma of the jaw (JOS) constituting 5% to 13% of all osteosarcoma is a locally aggressive malignant mesenchymal tumor with high tendency to local recurrence and the ability to produce tumor osteoid. Compared to osteosarcoma of the remaining skeleton (SOS) JOS metastasizes relatively rarely and relatively late. It differs significantly from SOS in its biological behaviour. CASE REPORT: The presented case deals with a 60-year-old male patient suffering from a newly occurred polypous mucosal tumor of the right-sided maxillary alveolar ridge bioptically diagnosed as a granulation tissue polyp first. After transmaxillary resection of the tumor and consultation of a bone tumor reference center the final diagnosis of a high-grade chondroblastic osteosarcoma could be made. The recommended radical resection of the tumor was declined by the patient because of the expected cosmetic consequences. After surgical reduction of the rapidly growing sarcoma chemotherapy according to the COOS/EURO-B.O.S.S. protocol was initiated at a stage when computed tomography showed diffuse metastatic disease to the lungs. Chemotherapy could delay the progress of the disease only temporarily. The patient died from respiratory insufficiency. CONCLUSION: In JOS radical surgical resection is the therapy of first choice. For substantiation of the diagnosis and central registration of the cases a bone tumor reference center should be contacted.     

Atelectasis of the maxillary sinus: report of a case of acute onset

INTRODUCTION: Maxillary sinus atelectasis is a rare pathology, characterized by a retraction of the maxillary sinus walls associated with tenacious mucus secretions filling the antrum. The disease usually develops in a chronic fashion, leading progressively to enophthalmos. This is sometimes associated with diplopia and midfacial depression. In these typical forms, maxillary sinus ventilation (via a middle meatal antrostomy) stops progression to retraction, but usually cannot reverse the phenomenon, resulting in a specific surgical procedure on the orbital floor or on the anterior wall of the sinus. MATERIALS & METHODS: We describe a case of maxillary sinus atelectasis with enophthalmos and midfacial depression, which appeared suddenly in one week, without nasal or sinus related symptoms. A middle meatal antrostomy performed rapidly enabled us to observe a reversal of the atelectatic process with recovery of the sinus volume, correction of the enophthalmos and disappearance of the associated diplopia, without the necessity for an additional surgical procedure. It is, to our knowledge, the first case described with such a rapid evolution.

Pneumosinus dilatans of the maxillary sinus: a case report and review of the literature

Pneumosinus dilatans (PSD) is an abnormal dilatation of one or more of the paranasal sinuses and must be included in the differential diagnosis of expansile lesions of the sinonasal tract. The frontal and sphenoid sinuses are the most frequently involved sites. Herein, we present the case of a 30-year-old woman with a 6-year history of right nasal obstruction and pain in the right maxillary region, elicited by rapid changes in atmospheric pressure. Computed tomography (CT) detailed an abnormal expansion of the right maxillary sinus resulting from a process of hyperpneumatization with no evidence of bone erosion, leading to the diagnosis of PSD. Restoration of permanent pressure equilibrium in the right maxillary sinus and improvement in the patency of the nasal fossa were achieved by a subtotal resection of the medial wall of the maxillary sinus by an endoscopic approach. Two years later, the patient was asymptomatic, and a CT scan showed no progression of the disease.
