Dear Editor,Optic perineuritis is a rare inflammatory disorder involving the optic nerve sheath and its adjacent *** condition shows dramatic responses to steroid treatment, although relapse is common. Additional characteristics of optic perineuritis include the sparing of central vision on a visual field test, relatively good initial visual acuity, and optic disc edemaI^l. Most cases are idiopathic, although some rare cases have been associated with specific infections, such as syphilis and viral infections, and autoimmune disorders including We- gener＇s granulomatosis, sarcoidosis, and giant cell arteritis.

Hepatocellular carcinoma （HCC） is one of the most frequent complications in patients with .liver cirrhosis. HCC without cirrhosis is rareand obviously a different entity. Treatment depends on tumor stage, liver function and general performance. Results of locoregional treatment, resection or liver transplantation are superior to those of medical therapy. Surgical approaches are potentially curative. Underlying cirrhosis is usually the limiting factor for the extent of resection and persists after resection. Liver transplantation eliminates both cirrhosis and, potentially, the tumor. Whereas surgery （functional liver capacity provided） may be performed even in advanced tumors, liver transplantation is advocated in less advanced （T2） tumors in order to keep the rate of recurrent tumor low. Responsible use of scarce grafts requires sticking to this rule.

To the Editor: Xanthogranulomatous cholecystitis(XGC) is an uncommon inflammatory disease of the gallbladder, and its incidence is reported to be 1.3%-5.2% [1]. XGC is diagnosed by histopathological examination, characterized by severe inflammatory destruction followed by a granulomatous reaction, marked proliferative fibrosis, and infiltration of inflammatory cells [2].
