This paper reported a case of juvenile trabecular ossifying fibroma（JTOF） originating from the uncinate process. The main clinical manifestation was nasal obstruction and epiphora. Contrast-enhanced sinus CT revealed an irregular heterogeneous soft tissue mass centered in the right uncinate process, with involvement of the right anterior ethmoid sinus, maxillary sinus ostium, frontal process of the maxilla, and partial nasolacrimal duct. The solid components of the tumor demonstrated enhancement on contrast imaging. The patient underwent endoscopic resection of the right sinonasal tumor under general anesthesia. Postoperative pathological examination confirmed the diagnosis of JTOF. No tumor recurrence was observed during the 3-month follow-up period.

OBJECTIVE: To investigate the histopathologic changes of ethmoid bone and its correlation with clinical types of chronic rhinosinusitis (CRS). METHOD: All ethmoid bones and mucosa from 180 patients with CRS after endoscopic sinus surgery were collected for histopathologic detection with HE staining. The number and the rate of cases were counted according to different histopathologic types. To analyze the correlation between ethmoid bones and clinical types of CRS, mucosal pathologic change, the CT-scanning types of sinusitis, the course of disease as well as operational history. RESULT: The ethmoid bone of all patients had varying degrees of histopathologic changes. There were 5 cases (2.78%) in stage I, 38 cases (21.11%) in stage II, 71 cases (39.44%) in stage III, and 66 cases (36.67%) in stage NIV. The histopathologic changes of ethmoid bone varied in different clinical types. In type I, there were 5 cases (8.33%) in stage I, 33 cases (55.00%) in stage II, 15 cases (25.00%) in stage III, and 7 cases (11.67%) in stage NV. In type I, there were 5 cases (8.33%) in stage II, 37 cases (61.67%) in stage mI, and 18 cases (30.00%) in stage NV. In type III, there were 19 cases (31.67%) in stage III, and 41 cases (68.33%) in stage NV. All histopathologic changes of ethmoid bone were statistically correlated (P < 0.01) with clinical types of CRS, pathologic mucosal change, the CT-scanning types of sinusitis, the course of disease as well as operational history. CONCLUSION Almost all patients with CRS manifest different-degrees of histopathologic changes, which are correlated with the clinical types of CRS, pathologic mucosal change, the CT-scanning types, the course of disease as well as operational history.

OBJECTIVE: To explore a rare anatomic malformation of ethmoid and its clinical features, as well as an effective way of treatment. METHOD: Four cases from 2000-2009 of the first affiliated hospital of china medical university were studied according to the symptom,CT scanning, pathological examination and treatment process, respectively. RESULT: Ethmoid bone gasification complicated with infection resulted in a rare anatomic and pathological disorder. The symptom and treatment were largely dependent on the size of gasification and degree of infection. CONCLUSION CT Scanning plays a critical role in the diagnosis. In most case,a surgical treatment under endoscope is generally applied as a suitable way for clinical therapy. The regular reexamination is recommended for preventing recurrence.
