Cholesterol granuloma of the maxillary sinus

Cholesterol granuloma (CG) of the maxillary sinus is very rare. In this study, the searching of the literature was performed with the keywords of cholesterol granuloma and maxillary sinus. All retrieved literature were reviewed throughout to identify and analyze all individual characteristics. Two additional cases in our hospital were also included. The result showed that, in the overall 37 cases, the ratio of male to female was about 3:1. Caucasian (14/37) and Turkish (10/37) were reported more frequently. CG of maxillary sinus had an opposite sex predilection compared with the fungus balls of the maxillary sinus. In addition, the comorbidity of these two diseases was found only in one patient in the literature. These results suggested that the different mechanisms other than poor aeration of the maxillary sinus played a role in the formation of CG of maxillary sinus. The diagnosis for CG of the maxillary sinus before operation is difficult, but the clear golden yellow rhinorrhea and hemorrhagic signs may provide a good diagnostic evidence. The symptoms were vague and about half of the patients presented with non-specific symptoms. Therefore, it seemed reasonable that CG of the maxillary sinus was under diagnosed in the clinical practice. Treatment consists of complete excision via Caldwell–Luc or endoscopic approach and provides a good prognosis. Bilateral involvements are rare but possible in this disease entity.     

Cholesterol granuloma in the maxillary sinus

A 35-year-old male complained of recurring headache and nasal obstruction over a 4-year period. A Caldwell-Luc operation was subsequently performed on the left maxillary sinus and a greenish appearing material was removed. Microscopic examination of the tissue specimen showed a granulomatous tissue with typical cholesterol clefts and inflammatory changes consistent with chronic sinusitis. This entity is presented and reviewed.     

Cholesterol granuloma and aspergilloma of the maxillary sinus

Cholesterol granuloma (CG) of the paranasal sinuses is rare. The proposed mechanisms of initiation are haemorrhage, impaired drainage and obstruction of ventilation. To the best of our knowledge, association of CG with a specific infection has not been described before. We have recently observed CG and aspergilloma of Aspergillus flavus type from the left maxillary sinus of a 58-year-old male patient presenting with nasal obstruction, headache and postnasal discharge. Any causative relationship between the two findings is obscure. The suspected mechanisms underlying aspergilloma and CG of the paranasal sinuses seems similar, since there is obstruction of ventilation and drainage. The cholesterol accumulation cannot be attributed to cellular components or breakdown products of the aspergillus as the major sterol of the plasma membranes of fungi is ergosterol, not cholesterol.

Cholesterol granuloma of the maxillary sinus resembling an invasive,destructive tumor

The case of a maxillary sinus cholesterol granuloma posing as a malignant tumor is presented. The patient was referred to the authors clinic with symptoms typical of maxillary sinusitis, but physical examination suggested the presence of neoplasm. Radiology also resulted in confusing, tumor-like pictures. Histological examination of a preoperative tissue sample identified the process as a cholesterol granuloma, which was removed by a classic Caldwell-Luc operation. The patient has been symptom free since the operation. The pathogenesis of cholesterol granuloma is described, and the problems of establishing a diagnosis without preoperative histology are discussed.     

Large pediatric sphenoid sinus cholesterol granuloma: Case report and review of the literature

Cholesterol granulomas are rare lesions in the paranasal sinuses, especially in children. Symptoms are nonspecific depending on the localization and extent of the mass. In a 6-year-old boy who presented with a headache and proptosis, computed tomography and magnetic resonance imaging showed a large expansile mass in the nasal cavity. The patient was started on intravenous antibiotics with no improvement. Following endoscopic biopsy, the mass was removed. Pathological findings were consistent with a cholesterol granuloma. Good clinical outcomes can be obtained with proper imaging studies. Endoscopic sinus surgical techniques allow the surgeon to clear and drain the affected sinus cavity.     

Inflammatory pseudotumour (plasma cell granuloma) arising in the maxillary sinus

Conclusions. Inflammatory pseudotumours in the maxillary sinus may present as malignant tumours and manifest locally aggressive features characteristic of such tumours. Despite their locally destructive features, they pursue a benign course after local excision. Objective. Inflammatory pseudotumour (plasma cell granuloma) is an uncommon non-neoplastic lesion comprising a proliferation of spindle myofibroblasts and chronic inflammatory cells. Despite its benign histopathological nature, it may exhibit aggressive behaviour that is yet to be characterized in the head and neck area. Material and methods. We present the cases of two adult patients with inflammatory pseudotumour arising from the maxillary sinus. Immunohistochemistry and polymerase chain reaction for immunoglobulin from tissue sections were performed to confirm the polyclonality of the infiltrating plasma cells. Results. CT and MRI disclosed expansive soft masses eroding surrounding soft and bony tissues. Histopathologically, the lesions were unencapsulated and composed of numerous plasma cells, histiocytes and spindle cells with minimal nuclear pleomorphism.

Asymptomatic leiomyosarcoma of maxillary sinus accompanied by primary mucocele

Summary A case of asymptomatic leiomyosarcoma of the maxillary sinus accompanied by primary maxillary mucocele is presented together with a review of the literature. The manifestation and symptoms, pathology in special reference to electron microscopic findings, treatment and prognosis, and origin of this tumor are discussed. Initially, this tumor should be treated by extensive surgical excision, but long-term follow-up is essential in the light of this high rate of local recurrence, and radical neck surgery is indicated for metastatic nodal disease.
