It is not uncommon that an endoscopist should differentiate metastatic or invasive cancer to the colorectum from primary colorectal cancer with its endoscopic appearances. This study reviewed the endoscopic appearances of 7 patients who were proved to have metastatic or invasive cancers to the colorectum, both clinically and pathologically. The primary cancers were uterine cervix cancers in 3 patients, advanced gastric cancers in two, and prostatic cancer in one. The endoseopic appearances of metastatic or invasive cancer showed several characteristic features with regard to those of primary colorectal cancer, as follows. 1) Multiplicity of lesions 2) Nodular lesion with unaffected mucosa or with mild degree of erosions 3) Concentric defarmities with conical extremities and the absence of shelving margins 4) Inflammatroy lesions with mucosal hyperemia, erosion, ulceration, and bleeding, but without definite mass formation.

Chronic sclerosing sialadenitis, also known as Kuttner tumor, is a chronic inflammatory disease of the salivary glands that is reported in a few cases in medical literature. Recent reports suggest that certain aspects of sclerosing diseases, including chronic sclerosing sialadenitis or dacryoadenitis, should be classified under immunoglobulin G4 (IgG4)-related sclerosing disease based on immunohistochemical studies. This study reports an unusual case of IgG4-related sclerosing disease appearing simultaneously in the lacrimal glands, submandibular glands, and extraocular muscles. A 56-year-old male presented with complaints of bilateral eyelid swelling and proptosis that began two years ago. Computed tomography confirmed that bilateral submandibular enlargements also existed five years ago in the subject. Orbital computed tomography and magnetic resonance imaging revealed bilateral lacrimal gland enlargement and thickening of extraocular muscles. Typical findings of chronic sclerosing dacryoadenitis were revealed upon pathologic exam of the right lacrimal gland. Immunostaining revealed numerous IgG4-positive plasma cells. Through these clinical features, we make a diagnosis of IgG4-relataed sclerosing disease in the subject.

Retroperitoneal liposarcoma comprises 12 to 45 percent of all liposarcoma. It has been a therapeutic dilemma and a less prognosis because of its tendency to attain a tremendous size due to early silent growth and difficult wide en bloc excision in the retroperitoneum. Here in we report a case of retroperitoneal liposarcoma in 51 year old male patient with a brief review of the literatures.

PURPOSE: We performed this study to evaluate the alterations in renal function for patients with ileal conduit and ileal orthotopic neobladder MATERIALS AND METHODS: From January 1999 to June 2004, 48 patients who had undergone radical cystectomy with urinary diversion were included in our study. The patients were divided into two groups according to the types of urinary diversion. One group consisted of 29 patients with ileal conduit and the other group consisted of 19 patients with ileal W neobladder. The mean age of the ileal conduit group and the ileal W neobladder group were 65.6+/-9.9 years and 60.8+/-8.3 years, respectively. The preoperative and postoperative blood urea nitrogen/creatinine (BUN/Cr) levels, postoperative complications and postoperative GFR, as measured by (99m)Tc-DTPA scans, were compared between the two groups. RESULTS: For the postoperative complications, stricture at the ureterovesical anastomosis site occurred in 1.7% (1/58 renal units) of the ileal conduit group and in 10.5% (4/38 renal units) of the ileal W neobladder group. Acute pyelonephritis occurred in 5.2% (3/58 renal units) of the ileal conduit group and in 5.3% (2/38 renal units) of the ileal W neobladder group. The pre- and postoperative serum BUN/Cr levels were 20.8/1.3 and 24.8/1.6, respectively, in the ileal conduit group, and 17.2/1.1 and 18.8/1.2, respectively, in the ileal W neobladder group. There were no statistical significant differences between the pre- and postoperative changes of the serum BUN/Cr levels for both groups. The GFR, as measured by (99m)Tc-DTPA scans, were 77.6 and 78.7ml/ min/1.73m2 in the ileal conduit group and the ileal W neobladder group, respectively. There were no statistical significant differences between the two groups. CONCLUSIONS: There were no significant differences in renal function between the ileal conduit and ileal W neobladder.

Fabella impingement syndrome after total knee arthroplasty (TKA) is a rare condition. However, the location of the inserted prosthesis and the size of the fabella are considered major causative factors. Thus far, a conventional surgical excision of the impinged fabella is recommended treatment for the impingement. A 72-year-old woman was diagnosed with degenerative arthritis of the knee. She complained of fabella impingement due to an incompletely excised bony spur behind the posterolateral femoral prosthesis after TKA. The fabella and remaining bony spur were removed using an arthroscopic procedure. The impingement has not recurred and the range of motion (ROM) of the knee was improved after a 12 months follow-up. Arthroscopic surgery might be an alternative treatment for fabella impingement after TKA.

BACKGROUND: The value of plasma concentration of 8-Methoxypsoralen(8-MOP) in the supervision of photochemotherapy has been recognized. However, plasma levels of 8-MOP were not proportionate to the degree of PUVA induced erythema and couldn't alone predict the degree of PUVA induced erythemal reaction. We made a speculation that the degree of PUVA induced erythema might correlate better with skin tissue levels of 8-MOP than plasma levels. Suction blister fluid(SBF) has been known to represent tissue fluid in the skin. So we per-formed a study of comparison of 8-MOP concentrations in both plasma and SBF. OBJECTIVE: Our purpose was to evaluate the correlation of the concentrations of 8-MOP in plasma and SBF 2 hours after oral administration of 0.6 mg/kg of 8-MOP. METHODS: Twenty six patients, aged between 16 and 50 years, undergoing suction blister surgery for vitiligo treatment, participated in this open study. Single oral doses of 0.6 mg/kg of body weight of 8-MOP were taken. Blood samples(5ml) and SBF(2ml) were collected at 2 hours after the drug administration, and 8-MOP concentration in plasma and SBF were quantitated by reverse phase high-performance liquid chromatography (HPLC). RESULTS: 8-MOP concentrations in plasma and SBF ranged from 18 to 545 ng/ml and 8 to 179 ng/ml, respectively. On the analysis of linear regression, a close-relation could not be observed between two SBF levels; measured and predicted values which were calculated from measured plasma and SBF concentrations (r²=0.583, P < 0.001). CONCLUSION: The correlation of plasma and SBF concentrations of 8-MOP is weak. So, SBF levels of psoralen are recommended for the study of PUVA erythemal reactions.

PURPOSE: To evaluate the effect of intravitreal injection on the corneal endothelium according to the injected drug. METHODS: The present study included 118 eyes of 113 patients who received intravitreal injection. Before each injection and 1 month after the injection, specular microscopy was performed to evaluate the corneal endothelial changes and central corneal thickness. We classified the patients according to the injected drug (bevacizumab 21 eyes, ranibizumab 20 eyes, aflibercept 47 eyes, dexamathasone implant 30 eyes), phakic or pseudophakic eyes, single or multiple injections and analyzed them retrospectively. RESULTS: The mean corneal endothelial cell density was 2,693.2 ± 298.2 cells/mm² before injection and 2,686.8 ± 288.7 cells/mm² 1 month after injection, and there was no statistically significant difference (p = 0.731). According to the kind of drug, the mean corneal endothelial cell density and central corneal thickness were not significantly different before and 1 month after injection in any of the 4 groups. CONCLUSIONS: There were no significant changes in corneal endothelium before and 1 month after intravitreal injection of the various drugs.

Despite improvements in therapy, cases in which relapse occurs are still common in children with acute lymphoblastic leukemia (ALL). Most relapses occur in the bone marrow, and extramedullary relapse is most commonly in the central nerve system. Soft tissue mass lesion or spinal cord involvement is extremely unusual in ALL relapse. We experienced a 13-year-old boy who presented with extremity weakness and pain. He was diagnosed with ALL 4 years ago and achieved complete remission after systemic chemotherapy. Imaging study revealed a paraspinal mass which was invading the S1-2 vertebral body. Histopathologic examination revealed infiltrates composed of immature lymphoblasts with morphology identical with that of initially diagnosed bone marrow aspiration. Studies on bone marrow were negative for disease at this time. He was treated with irradiation and intrathecal chemotherapy, in addition to systemic chemotherapy. The mass has nearly disappeared, and he is planned for allogeneic bone marrow transplantation.

A case of Carney complex in a Korean patient is presented. The patient had the characteristics of Carney complex including skin lesions, positive family history, and multiple myxomas including a superficial angiomyxoma in the perianal area. An extensive genetic analysis revealed a novel mutation in the protein kinase A type I-a regulatory subunit (PRKAR1A) gene, but not in the phosphodiesterase type 11A (PDE11A) gene. This is the first case wherein extensive genetic studies were performed in a patient with Carney complex in Korea.
