Venous hemangioma is a vascular tumor that has been reported by such diverse names as; "cirsoid aneurysm", "arteriovenous hemangioma", "acral arteriovenous tumor" according to the author's opinions of its origin and histopathologic classification. It is benign and rarely biopsied, and it is also rarely reported in dermatology literature. We present two cases of venous hemangioma. The first case was a 64-year-old man who was presented with an elliptical dark-red plaque with overlying several grouped papules on the left periorbital area which had been present for 7 years. The second case was a 56-year-old man who was presented with a single red papule on the right postauricular area which had been present for 4 months. Histopathologically, there were a well-circumscribed proliferation of thick-walled muscle-containing blood vessels in the dermis. Intermingled with the thick-walled blood vessels, there were also thin-walled dilated blood vessels. In both cases, the thick-walled blood vessels resembled arteries, but they lacked elastic fibers on the Verhoeff van Gieson stain.

Cutaneous smooth muscle hamartomas are benign proliferations of smooth muscle bundles within the dermis. They can be congenital or acquired, and most cases are congenital. Congenital smooth muscle hamartomas (CSMHs) usually manifest at birth as well-circumscribed, frequently hypertrichotic, hyperpigmented or skin-colored patches or plaques on trunk or extremities. We report a case of CSMH in a 10 year-old girl, who showed a localized skin-colored patch showing prominent follicular papules on the lateral aspect of her right upper arm, which were found at birth. There was no hypertrichosis and the pseudo-Darier sign was negative. This patchy follicular variant is the less common clinical type of the disease.

Gardner's syndrome is a familial disease consisting of gastrointestinal adenomatous polyposis, osteomas of the mandible, skull, and long bones, and a variety of sol tissue lesions, including sebaceous cysts, fibromas, lipomas, and desmoid tumors. The colon is the most common site for polyposis, but the stomach, duodenum, small bowel, and periampullary area may also be involved. The diagnostic evaluation, malignant potential, and management is identical to that for familial adenomatous polyposis. The extracolonic manifestations of Gardner's syndrome are frequent and varied. Gardner's syndrome is inherited as autosomal dominant traits. Authors experienced one case that is a 32 year old female patient who had colonic and duodenal multiple polyposis, desmoid tumor in abdominal wall and right mesocolon and odontoma on mandible.

Although a number of remedies like corticosteroids, retinoids, griseofulvin, PUVA, cyclosporine, antibiotics, dapsone, cyclophosphamide, surgery, methotrexate, radiation therapy, antimalarial drugs, psychotharapy and psychiatric medications have been used to treat lichen planus, there were no specific methods until now. We report herein an interesting case of lichen planus in which complete healing was achieved by griseofulvin administration. The patient was a 54-year-old male who for 3 months had variouly sized and shaped, flat-topped, scaly, violaceous papules and plaques on the whole of his body. We confirmed the patients disease as lichen planus by a histopathologic examination of a skin biopsy specimen and gave him 500mg ultramicronized griseofulvin daily in divided dosages. After 12 weeks of the medication nearly all of the skin lesions were regressed, and by 14 weeks all skin lesions had disappeared leaving hyperpigmentation. Up to now, l9 months after discontinuation of the medication, no recurrence of the disease has been noted.

PURPOSE: To introduce and assess the results of punctoplasty using a radiofrequency surgical unit for punctal stenosis. METHODS: Patients who complained of epiphora, had an intact lacrimal pathway below puncti, and underwent punctoplasty with the Ellman Surgitron F.F.P.F were evaluated in the present study. RESULTS: A total of 19 patients (31 eyes) were included in the study. The average age was 55 years (+/-15.7 years). At the last follow-up visit, 27 eyes (87%) had patent puncti, 1 eye became stenotic again, and 3 eyes were completely obstructed. Twenty-two eyes (71%) showed almost complete disappearance of dye on the fluorescein dye-disappearance test (FDDT). Twenty-five eyes (81%) had symptomatic improvement. No significant complication was reported postoperatively. CONCLUSIONS: Punctoplasty with a radiofrequency surgical unit is a simple and effective method for punctal stenosis.

PURPOSE: Preoperative chemoradiation therapy for rectal cancer seems to improve local control, anal sphincter preservation, resectability, and possibly survival in patients. However, there are several adverse effects, too. The aim of this study is to analyze the disadvantages of preoperative chemoradiation for rectal cancer. METHODS: We retrospectively reviewed 139 patients who were treated by using preoperative chemoradiation for an adenocarcinoma of the rectum between January 1995 and December 2004. All patients had fixed or locally advanced lesions, as determined by digital rectal examination. No distant metastasis was proven before preoperative chemoradiation. All of the patiedts received the full scheduled dose of radiation (range, 5,000~5,400 rad). Concurrent intravenous chemotherapy with 5-fluorouracil (425 mg/m2/day) and leucovorin (45 mg/day) was administered continuously on days 1~5 and 29~33. The mean interval between chemoradiation and surgery was 4~6 weeks. After preoperative chemoradiation, 117 patients underwent an operation. We reviewed the side effects of preoperative chemoradiation, postoperative complications, and distant metastases detected during the preoperative period after preoperative chemoradiation and during the operation. RESULTS: The side effects of preoperative chemoradiation were diarrhea (23%), radiation dermatitis (2.2%), fistula (0.7%), sepsis (0.7%), and rectal bleeding (0.7%). Two patients died from sepsis and rectal bleeding. The postoperative complications were bowel obstruction in 9 cases (7.7%), wound seroma in 8 cases (6.8%), wound infection in 5 cases (4.3%), anastomotic leakage in 5 cases (7.1%), rectovaginal fistula in 2 cases (2.8%), an enterocutaneous fistula in 2 cases (1.7%), and a vesicocutaneous fistula in 1 case (0.8%). Distant metastases were detected in 14 patients (10.1%) after preoperative chemoradiation. CONCLUSIONS: Although preoperative chemoradiation can be performed safely, careful management for the side effects of preoperative chemoradiation and for postoperative complications is necessary. We need a more sensitive study method for detecting distant metastasis of rectal cancer, especially during scheduled preoperative chemoradiation.

Alkaline phosphatase level was identical order with the viable cell rate. SEM examination revealed that the PDL fibroblasts adherent on culture dish (control) and group A were spindle-shaped, but on group B and C, the cells were round-shaped without processes.

Journal of the Korean Surgical Society 2004;66(3):205-211
PURPOSE: Mechanical bowel preparation aims to eliminate solid stool in the colon prior to colonoscopy and colorectal surgery. During colorectal surgery, a clean bowel has advantages such as a lower bacterial load, reduced chance of spillage of fecal content, and easiery handling of the bowel. The aim of this prospective trial was to compare polyethylene glycol (PEG) and sodium phosphate solutions for colorectal surgery according to patient's tolerance, side effects, cleansing quality, and postoperative complication. METHODS: Eighty patients prospectively received either a standard 4 liter PEG solution or a 90 ml oral sodium phosphate solution. Patient's tolerance for solution was assessed with a detailed questionnaire. Before and after bowel preparation, we checked the patient's body weight, blood pressure, pulse, and biochemical parameters such as hematocrit, serum electrolyte, blood urea nitrogen, and creatinine levels. The cleansing quality was checked by the surgeon during the operation. Statistical analysis was performed using the chi-square test for patient's tolerance, body weight, blood pressure, pulse, and postoperative complication and using the paired t-test for biochemical parameters with SPSS 11.0 version. RESULTS: The PEG and sodium phosphate solutions were each administered to 40 patients, separately. Thirty-seven patients (92.5%) had colorectal cancer in each group. The other underlying diseases were benign tumor, multiple polyps, diverticulitis, and familiar adenomatous polyposis. In comparing tolerance, there was no significant difference in the rate of patients who complained of difficulty on the questionnaire for discomfort (P=0.954), nor in the rate of patients who complained of severe subjective symptoms such as nausea, vomiting, abdominal pain, dizziness and sleep loss. The cleansing quality, body weight, blood pressure, pulse change and postoperative complication rates were not significantly different. In the PEG group, hematocrit (P=0.008), serum magnesium (P=0.03), phosphorus (P= 0.004), and blood urea nitrogen (P=0.001) were decreased and serum chloride (P=0.001) was increased. In the sodium phosphate group, serum sodium (P=0.001) was increased and serum potassium (P=0.018) was decreased. There was no significant changes in serum calcium (P=0.086) and phosphate (P=0.191) in the sodium phosphate group. CONCLUSION: In both groups, there was no significant difference in patient's tolerance, cleansing quality and postoperative complication rate. Though there were some biochemical changes between the two groups, they were not significant clinically. Therefore, the sodium phosphate solution can be substituted for the PEG solution in preoperative bowel preparation.
