A case of large dermoid cyst in the floor of the mouth.

Dermoid cysts in the floor of the mouth are rarely observed. When they develop, they do not appear until they grow large enough or appear through infection. Some operative approaches and management have been performed to large dermoid cysts in the floor of the mouth with some variations. Intra-oral approach is the most useful for cosmetic appearance. We presented a 24-year-old female who underwent expedient surgical excision using finger end serviceable enucleation through the intra-oral approach.

A case of relapsing polychondritis involving placement of an expandable metallic stent.

Relapsing polychondritis is a relatively uncommon disease characterized by recurrence of progressive inflammation of cartilaginous structures. Laryngotracheal involvement occurs in 50-70% of cases, and occasionally results in acute airway obstruction. We reported a case of relapsing polychondritis with severe tracheal stenosis that was treated by the placement of two expandable metallic stents. A 58-year-old man was hospitalized with fever and breathing difficulties. A tracheostomy was performed and a silicone T-tube was placed. A diagnosis of relapsing polychondritis was made based on the biopsy from auricular and tracheal cartilages. Two expandable metallic stents were placed in the trachea to bilateral main bronchus. This dilated the airway lumen and resulted in the dyspnea disappearing completely. However, 18 months later a sudden massive hemorrhage occurred through the tracheostoma, and he died of respiratory failure. Autopsy showed a tracheoinnominate artery fistula. We discuss the management of relapsing polychondritis with severe tracheal stenosis.

The management of possible fishbone ingestion.

OBJECTIVE: We assessed the usefulness of computed tomography (CT) in cases of suspected impaction of fish bones in the esophagus. The findings of this study were also compared with those of studies in which surgery was used to remove or confirm the presence of fish bones. We accordingly propose a management protocol to ensure optimum outcome for patients with a history of fish bone ingestion. METHODS: X-ray and CT imaging were performed in 76 patients in whom esophageal impaction of fish bones was suspected. RESULTS: Plain X-ray revealed impacted fish bones in 17 patients (22%), soft-tissue swelling but no evidence of foreign body in 5 (7%), and no abnormal findings in 54 (71%). These findings were apparent on CT scans in 31 (41%), 8 (10%), and 37 (49%), respectively. Of the 31 patients in whom CT revealed a fishbone, 17 (55%) also exhibited X-ray evidence of foreign body. Of the remainder, X-ray revealed only soft-tissue swelling in 3 (10%), and was unremarkable in 11 (35%). Among the 5 patients in whom X-ray demonstrated only soft-tissue swelling, CT was positive for foreign body in 3 (60%). Of the 54 patients in whom X-ray appearances were normal, CT revealed foreign bodies in 11 (20%) and other abnormalities in 6 (11%). CONCLUSION: In the present study, sensitivity and specificity of plain X-ray was 54.8% (17 of 31) and 100% (45 of 45), respectively. However, for CT, both sensitivity and specificity were 100%. CT was determined to be very useful in the diagnosis of impacted fish bones in the esophagus.
