BACKGROUND AND OBJECTIVE: Intrasinus ossification is rarely observed in the imaging study of paranasal sinus. The pathologic findings and the treatment principles of the radiodense lesions which are located in the inflammatory lesion of the paranasal sinuses are not clarified enough. In this study, we try to describe the CT findings and histopathology of intrasinus calcification in chronic paranasal sinusitis. MATERIALS AND METHODS: Ten patients who underwent sinus surgery for the abnormal bony calcification were included in this study. The shape and location of intrasinus calcification were evaluated in the CT. The pathologic specimens were reviewed. RESULTS: Most of the patients had high Hounsfield unit at CT imaging. Osteomas were found in 7 patients, fungal sinusitis in 2 patients, and the new bone formation in a patient. Osteoma and the new bone formation were located at the periphery of the sinus cavities. The calcifications in fungal sinusitis were found at the central of the sinuses. Infiltration of the inflammatory cells were found in the matrix of fungal sinusitis, but not in others. CONCLUSION: Intrasinus radiodense lesions are different in the location and shape according to the pathology. The findings in the CT imaging of intrasinus calcification are helpful for the differentiation of these lesions.

A 39 years old male patient was admitted with the right of facial abnormalities and gradually protruding in right eye more than 30 years. CT shows high mixed density, clear boundary, and the right eye was crowded to the right. Giant tumor had completely been excised, and the result was fine. The outline figure and function of patients were obviously improved. The pathological examination after resection showed ossifying fibroma.

8.One case of pleomorphic adenoma originates from inferior nasal turbinate.
Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2014;28(20):1622-1622
Pleomorphic adenoma (PA) is the most common benign tumor of the salivary glands. Originating from the nasal cavity is very rare. This paper reports one case of pleomorphic adenoma of the inferior nasal turbinate to analyze the clinic characteristic of this disease. Although these tumors are rarely seen in everyday practice, one should consider this possibility as an uncommon aetiology when confronted with an intranasal mass.

Rosai-Dorfman disease in nasal cavity and nasal sinuses is known as an idiopathic proliferative disease of histiocytes with a distinct morphologic feature and is very rare. It is easy to relapse and be misdiagnosed. In on case, the infiltrating histiocytes had large round or oval nuclei. The cytoplasm was abundant, granular or vacuolated and foamy. Immunohistochemical studies showed that the histiocytes were strongly reactive with antibodies against S100 and CD68. The diagnosis of extranodal RDD in the paranasal sinuses could be differentiated with rhinoscleroma, eosinophilic granuloma, plasmacytoma, or fibrous histiocytoma. It showed that the identification of the distinctive histiocytes which are typically immunoreactive to S100 and CD68 can be quite helpful for correct diagnosis.
