RESUMO
We report a case of a 64-year-old Japanese man with adenoid cystic carcinoma. An elevated lesion covered by intact epithelium in the thoracic esophagus was found in September, 2007 and been followed. After dysphagia appeared follow-up endoscopy was performed in January, 2010, and morphological change into a protruding tumor was recognized. Since adenoid cystic carcinoma was detected by endoscopic biopsy, the patient underwent esophageal resection. The resected specimen showed a cribriform pattern and a certain amount of mucous substance which was positive for Alcian blue, within a solid nest. The tumor cells were positive for S-100 protein and negative for αSMA, so the tumor was diagnosed as an adenoid cystic carcinoma.

PURPOSE: To report the performance of a newly devised technique, inferior meatal dacryorhinotomy (iDR), for membranous PNLDO (lower PNLDO). DESIGN: Retrospective, nonrandomized clinical trial. METHODS: Forty cases (37 patients) who ranged in age from 42 to 89 years old with lower PNLDO were treated by iDR, which is intubation that is assisted by dacryoendoscope, nasal endoscope, and radio-frequency scalpel. The obstructed site was incised with a radio-frequency scalpel without osseous ablation, after which silicone tubes were placed temporarily. RESULTS: Postoperative follow-up evaluation showed that the success rate was 87.5% after 6 months to 2 years. CONCLUSION: The iDR technique is minimally invasive and effective for lower PNLDO.

PURPOSE: To investigate the site of primary nasolacrimal duct obstruction (PNLDO) using a dacryoendoscope and nasal endoscope. DESIGN: Retrospective, observational case series. METHODS: After local anesthesia, dacryoendoscopy and nasal endoscopy were performed in 149 cases (138 Japanese subjects) of PNLDO. Membranous nasolacrimal duct obstruction was termed as lower PNLDO, and occlusion at sac/duct junction termed as higher PNLDO. RESULTS: The incidence of lower PNLDO was 26.8% (40 of 149 cases), and 109 cases (73.2%) were diagnosed with higher PNLDO. CONCLUSIONS: The dacryoendoscope is extremely useful to observe directly and evaluate the site of obstruction with accuracy in PNLDO. The higher and lower PNLDO may have a different etiologies.
