Objective To explore the feasibility and clinical value of metallic stent in the management of unresectable hepatic portal cholangiocarcinoma. Methods A study was investigated in 17 patients with unresectable hepatic portal cholangiocarcinoma from January 1998 to January 2006. A memory alloy biliary stent was placed into the obstructive bile duct for internal biliary drainage. Results Patients’ jaundice disappeared within 2 weeks after the stent placement. Cholangiography via the drainage tube showed patent bile ducts. Follow-up surveys in 16 patients for 4~30 months (mean, 11.5 months) revealed a survival time of 4~20 months (mean, 11 months) in 13 fatal patients. The remaining 3 patients had survived 10, 12.5, and 30 months, respectively. Conclusions Placement of memory metallic biliary stent for patients with unresectable hepatic portal cholangiocarcinoma is an ideal palliative therapy, which is simple and effective for reducing jaundice.

Xeroderma Pigmentosum is a hereditary disorder characterized sunlight sensitivity multiple cutaneous malignancies, usually basal and squamous cell carcinoma and frequent ocular complication. The auther has presented recently treated one case of limbal squamous cell carcinoma associated with Xeroderma Pigmentosum in 15 years old male. It was reviewed clinically with the literature.

Authors have experienced with a rare case of marginal blepharitis caused by pubic lice, which was confirmed by slit-lamp and light microscopic examinations and resulted with a good outcome with appropriate treatment. Patient was a 11 year-old Korean male who has been complaining of itching sensation on the upper lid margin, conjunctival congestion, eye wax and foreign body sensation in both eyes for more than three months. Authors speculate that the possible contact or source of this invader probably is his mother since we have found same ova and worms from the pubic region of his mother. It is recommended that if a patient complains of a blepharitis witli stubborn itching sensation which is not controlled by a ordinary treatment, the therapist should be kept in mind of this parasitic intruder.
