A dermoid cyst of the head and neck region is a relatively infrequent occurrence and accounts for only 6.9% of all dermoid cysts. Its anatomical distribution is the orbit, floor of the mouth, other midline and nose in the order of frequency. A dermoid cyst of the parotid gland is extremely rare, and due to this and the absence of pathognomonic findings, it is often difficult to diagnose preoperatively. Thus thorough and careful examination including ultrasonic study is needed to evaluate this lesion. It must be differentiated from malignant tumors and other cystic lesions. Dermoid cysts usually recur after simple excision, so it is mandatory to excise it completely with a parotidectomy. This paper presents two cases of parotid gland dermoid cyst with a brief review of the literature.

Tuberous sclerosis is an autosomal dominant disorder characterized by seizure, mental retardation and harmatomatous lesions in multiple organs. The renal lesions of tuberous sclerosis are multiple angiomyolipomas often associated with cysts of various sizes. A 47-year-old man who had been on hemodialysis for 12 years was admitted to our hospital because of sudden onset of right flank pain. He had polycystic kidney disease and adenoma sebaceum. Abdominal computed tomography showed an enlarged right kidney with massive hemorrhage, and renal arteriography showed massive bleeding. Immediate transarterial embolization and radical nephrectomy on the right kidney was done. Pathologic examination revealed ruptured renal angiomyolipoma, confirming that he had contiguous gene syndrome. We experienced a case of tuberous sclerosis with spontaneous rupture of renal angiomyolipoma in a hemodialysis patient with autosomal dominant polycystic kidney disease.

PURPOSE: We studied to investigate the minimum concentration and preservation time of ethanol for sterilization of donor sclera. METHODS: Fresh sclera was inoculated with Staphylococcus epidermidis(ATCC 155), Staphylococcus aureus(ATCC 28213), Pseudomonas aeruginosa(ATCC 27843), and transferred to preservative vials containing the concentration of ethanol(10, 30, 50, 70, and 90%) or trypticase soy broth(TSB, control) and stored at room temperature. The sclera was then homogenized, plated on blood agar, and incubated at 37 degreesC for 24 hours. Colonies were counted at 6, 12, 24, 48, and 72 hours. RESULTS: Staphylococcus epidermidis and Staphylococcus aureus were recovered from contaminated sclera plates preserved in 10% ethanol until 72 hours and in 30% ethanol until 12 hours, but no bacteria was recovered from the sclera preserved in more than 50% ethanol(P<0.05). Pseudomonas aeruginosa was recovered in 10% ethanol until 72 hours but not recovered in more than 30% ethanol until 24 hours(P<0.05). However, all three species were recovered from the control sclera preserved in TSB until 72 hours. CONCLUSIONS: From the above results it is concluded that the concentration of more than 50% ethanol for at least 6 hours is recommendable as human sclera disinfectants.

This clinical study was conducted to survey 300 cases of total laparoscopic hysterctomy (TLH) by the Department of Obstetrics and Gynecology of Boram Hospital in Ulsan, Korea from January, 2000 to June, 2001. TLH has been described in much of the recent literature. We analyzed 300 cases of TLH to evaluate the clinical data such as distribution of age, parity, clinical indication, previous operation history, type of surgery, operation time, weight of uterus, Hb change of post-operation first day and the complications of using this technique. The mean age of patients was 41.3. The mean parity of patients was 2.6. The clinical indications for TLH were myoma (72.3%), adenomyosis (11.3%), PID (5.3%), CIS (4%) and others (5.7%). The most previous operation was bilateral tubal ligation. Others were cesarean section, appendectomy. The most concomitant procedure with TLH was posterior colpoperineorrhaphy. Salpingo-oophorectomy and appendectomy were also carried out concomitantly. The mean operation time was 124 minutes. The mean weight of the uterus was 230 gm. The mean Hb change post-operation on the 1st day was 1.3g/dL. The complications of TLH were bleeding to need blood transfusion, ureteral injury and bladder injury. Thus this technique can be safely performed by skilled laparoscopists for properly selected patients but there is a need for prospective studies for comparision with various laparoscopic hysterctomies.

Cutaneous epidermal cysts are benign lesions commonly experienced in the outpatients department, but the occurrence of a squamous cell carcinoma arising within a cutaneous epidermal cyst is extremely rare. Herein, a case of a squamous cell carcinoma arising from a recurrent epidermal cyst is reported.

To determine whether hyperplastic polyps found in the distal colon are associated with proximal adenomas, and to judge whether patients with distal hyperplastic polyps found during sigmoidoscopy might benefit from full colonoscopy. METHODS: We retrospectively analyzed 2333 consecutive patients who were examined with colonoscopy between January 1991 and December 1994. RESULTS: 247 of 2333 patients (10.6%) had one or more colonic polyps. The prevalence of adenomatous polyps alone was 72.5%, hyperplastic polyps 22.7%, and both 0.52%. The proportion of patients with distal hyperplastic polyps and proximal adenomatous polyps (4.4%) was not significantly different from the proportion of those without distal hyperplastic polyps (1.6%). Patients with distal adenomatous polyps, on the other hand, were significantly more likely to have proximal adenomatous polyps than those without distal adenomatous polyps. CONCLUSIONS: Distal hyperplastic polyps are not strong predictors of risk for proximal adenomatous polyps. Based on the results of this study, we do not believe that finding a hyperplastic polyp during sigmoidoscopy justifies doing a full colonoscopy to search for proximal adenomatous polpys.

Upper gastrointestinal tract angiodysplasia is rare, but it is an important cause of upper gastrointestinal bleeding. We experienced a case of hemorrhagic angiodysplasia of duodenal bulb in a patient under chronic hemodialysis due to chronic renal failure. Repeated upper GI endoscopy revealed an angiodysplasia at the posterior wall of the duodenal bulb. It was successfully treated by bipolar electrocoagulation. We report a case of angiodysplasia in chronic renal failure patient with the review of the literatures.

Carcinoid tumors arise from enterochromaffin cells that are located predominatly in the gastrointestinal mucosa. The vast majority of rectal carcinoid tumors are benign and can be safely treated by local excision. Lesions larger than 2 cm and invading the museular wall of the rectum should be considered malignancy and treated by more radical surgery such as abominoperined resection. We report 6 cases of rectal carcinoid tumor, three cases of them were less than 1 cm in size without metastasis. Two of these, small carcinoid tumor were treated with endoacopic polypectomy and one was treated with segmental resection. The others were 2.0 cm or larger in size with regional or liver mestasis. They were treated with segmental resection or electrical fugalization for tumor and transcatheter arterial embilization for liver metastasis or none.

PURPOSE: To report the clinical results and efficacies of one stage reverse lateral supramalleolar adipofascial flap for soft tissue reconstruction of the foot and ankle joint. MATERIAL AND METHODS: We performed 5 cases of one stage reverse lateral supramalleolar adipofascial flap from Jan 2005 to Sept 2005. All patients were males and mean age was 50(36~59) years old. The causes of soft tissue defects were 1 diabetic foot, 2 crushing injuries of the foot, 1 open fracture of the calcaneus, and 1 chronic osteomyelitis of the medial cuneiform bone. Average size of the flap was 3.6(3~4)x4.6(4~6) cm. All flaps were harvested as adipofascial flap and were performed with the split-thickness skin grafts (STSG) above the flaps simultaneously. RESULTS: All flap survived completely and good taking of STSG on the flap was achieved in all cases. There were no venous congestion and marginal necrosis of the flap. In diabetic foot case, wound was healed at 4 weeks after surgery due to wound infection. There was no contracture on the grafted sites. Ankle and toe motion were not restricted at last follow up. All patients did not have difficulty in wearing shoes. CONCLUSION: The reverse lateral supramalleolar adipofascial flap and STSG offers a valuable option for repair of exposure of the tendon and bone around the ankle and foot. Also one stage procedure with STSG can give more advantages than second stage with FTSG, such as good and fast take-up, early ambulation and physical therapy, and good functional result.
