In both cases, endoscopic examination revealed multiple yellowish plaques sized 1 to 3mm in diameter in the esophagus, which were initially interpreted as probable candida infection, xanthoma, or glycogenic acanthosis. Histological examinations of biopsy specimens showed clusters of clear cells in the squamous cell epithelium. They had pale cytoplasm with centrally located small nuclei and closely resembled sebaceous glands of the skin, and were histologically interpreted as heterotopic sebaceous glands of the esophagus. Along with recent advances in endoscopic technique, reported cases of heterotopic sebaceous glands in the esophagus are increasing. However, the histogenesis of heterotopic sebaceous glands in the esophagus has not been well established and remains to be established. The present report concerns two cases of heterotopic esophageal sebaceous glands accompanied by some immunohistochemical studies.

We compared the clinical results of radical cystectomy between elder and younger patients. Materials and Methods : We retrospectively reviewed the records of 59 patients who underwent radical cystectomy for bladder carcinoma between 1993 and 2006. Two groups were compared:≦75 years old (n=49) and ＞75 years old (n=10). Overall survival and disease specific survival were evaluated using Kaplan-Meier methods and a multivariate Cox model. Results : There were no significant differences in blood loss and transfusion volume during the operation. However, the operative time in the younger patients was longer than in the elderly patients (p＜0.01). The rate of complication in the elderly patients was not different from that in the younger patients (p=0.86). The 5-year disease specific survival rates for patients ≦75 and ＞75 years old were 80.1% and 42.5%, respectively (p＜0.01). The elderly did not receive adjuvant chemotherapy. Conclusions : In the current series, almost all the elderly patients tolerated radical cystectomy compared with the younger patients. Further work is needed to determine indications for radical cystectomy and to develop strategies to improve cancer control in elderly patients.
