A delayed primary esophago-esophagostomy of a case of long-gap esophageal atresia without tracheoesophageal fistula was performed in success with three months' intermittent periodic bougienage of the upper pouch via mouth as well as the lower esophagus through Janeway gastrostomy. Meanwhile, an effective continuous sump suction from the upper pouch seemed to be a critical part of the patient management. The extra length of esophagus for primary anastomosis could be achieved by a circular myotomy. Stricture at the myotomy site, found 4 months later, was treated with periodic pneumatic baloon dilations only with temporary symptomatic reliefs. After 4 months' trials, operative esophagoplasty was performed successfully. A careful follow-up schedule for the myotomy site would be required for early detection of stricture. The previous neonatal patient is currently 8 years old, healthy school-boy, and has a normal barium swallow without stricture or gastroesophageal reflux.

Primary cutaneous mucinous carcinoma (PCMC) is a rare low-grade malignant neoplasm derived from the eccrine glands. PCMC most commonly arises in the head and neck, with the eyelid being the most common site of origin. This case report describes a 51-year-old male with a painless, pigmented superficial nodular lesion over his right lower eyelid. The lesion was considered to be benign, and the initial treatment was simple excision with a 3-mm margin. However, histologic examination revealed the diagnosis of PCMC, and the patient underwent re-excision of the tumor site with an additional 3-mm margin from the initial scar. Histologic study of this second margin was free of any malignant cells. The patient experienced no postoperative complication or recurrence after 2 years. In our case, the skin lesion had benign morphologic findings and was strongly suspected to be a benign mass. Physicians should be aware of this tumor and be able to differentiate it from benign cystic or solid eyelid lesions.

A 17 month-old girl presented in the pediatric clinic on November 27th, 1990 with a neck mass. The mass was 2 cm in diameter, firm in consistency and movable on the upper pole of the thyroid cartilage in the midline. The technetium thyroid scan showed a hot reactivity at the compatible site of the mass, but no other radioactivity in either site of the normal thyroid positions. At her second visit on January 23th, 1996, the mass had enlarged up to 3.5cm in diameter in the same location of the neck. The follow up thyroid scan revealed a walnut sized, snowman-like radioactivity. One of the snowman-like double images seemed to be a lingual ectopic thyroid and the other a midline ectopic thyroid remnant in the infrahyoid level. This interpretation was supported by the computed tomography of the neck, which showed a ligual mass in the foramen cecum area and an another mass in the anterior comis-sure of the larynx in the mildline. Thyroid function test was normal except a slightly increased TSH. As a result of this changing pattern of thyroid radioactive images, a case of a lingual thyroid as well as another midline ectopic thyroid tissue at the infrahyoid level is reported.

Neurofibromatosis type 1 (NF1) is an autosomal dominant disease characterized by neurological, cutaneous, and ophthalmological manifestations. A 33-year-old woman with typical symptoms of NF1 visited Ajou University Hospital. Screening of the whole-messenger RNA region of NF1 at the complementary DNA level by polymerase chain reaction-direct sequencing confirmed the presence of an NF1 mutation at the genomic level. The mutation analysis revealed an in-frame skipping of exon 46 (c.6757_6858del) caused by a point mutation (c. 6792C>A) in exon 46. In this report, we have described the first Korean case of a proband with NF1 that carries an allele with an exon 46 deletion caused by an exonic splicing enhancer site mutation, leading to the skipping of the whole of exon 46 (c.6757_6858del).

Frey's syndrome and infra-auricular depressed deformities are the ones of the most common complications that can occur after total parotidectomy. We report 1 case of pleomorphic adenoma occurred in the deep lobe that obtained good results from using acellular dermal matrix (ADM) after total parotidectomy. A 24-year-old man visited the hospital with oval shape mass in right mandibular angle which of 4 cm in size was found in the deep lobe of right parotid gland from Magnetic resonance imaging scanning and a pleomorphic adenoma was suspected. A total parotidectomy was performed while preserving the facial nerve. The material known as ADM were placed in the depressed part from where the mass was removed, and the site was sutured. The surgery site was healed well without any complications such as Frey's syndrome or infra-auricular depressed deformities. The pathological result was confirmed as pleomorphic adenoma. In addition to these advantages, it does not have little potential of deformation by the gravity after the surgery, and there is no restraint on circulation, which makes fabrication free and each deformation into various shapes can be described as another advantage of the reconstruction using the ADM.

We performed three replacement operations of great venous obstruction with Dacron prosthesis from July, 1980 to Nov. 1980. Summary of 3 cases as belows: 1) Inferior vena cava obstruction . 43 years old male was admitted because of abdominal distension and marked superficial collateral circulation on chest and abdomen. Inferior vena cavogram showed complete obstruction of I. V .C. just below hepatic vein. Bypass operation was done between Rt atrium '||'&'||' I. V.C. (just above renal vein) with Woven Dacron prosthesis (22mm in Diameter) under ex tracorporeal ci rculation. 2) Superior vena cava obstruction . 21 years old male was admitted because of facial edema and irritative cough. Well circumscribed lobulated mass was located at ant. superior mediastinum and extended to Rt. thorax in chest P-A view. Woven Dacron prosthesis (10mm in Diameter) was replaced at involved S.V.C. segment after Rt. upper '||'&'||' middle lobectomy with tumor resection. 3) Common iliac vein obstruction (Lt) . 64 years old female was admitted because of generalized edema and tenderness of Lt. lower extremity. Venography of Lt leg showed complete obstruction of common iliac vein. Woven Dacron prosthesis (10mm in Diameter) was replaced at obstruction site.eplaced at obstruction site.

The keystone flap is a fascia-based island flap with two conjoined V-Y flaps. Here, we report a case of successful treatment of a trochanter pressure sore patient with the traditional keystone flap. A 50-year-old male patient visited our department with a $3{\times}5cm$ pressure sore (grade III) to the left of the greater trochanter that was covered with eschar. Debridement was done and the defect size increased to $5{\times}8cm$ in an elliptical shape. Doppler ultrasound was then used to locate the inferior gluteal artery perforator near the wound. The keystone flap was designed to the medial side. The perforator based keystone island flap covered the defect without resistance. The site remained clean, and no dehiscence, infection, hematoma, or seroma developed. In general, greater trochanter pressure sores are covered with a perforator based propeller flap or fascia lata flap. However, these flaps have the risk of pedicle kinking and require a large operation site. For the first time, we successfully applied the keystone flap to treat a greater trochanter pressure sore patient. Our design was also favorable with the relaxation skin tension lines. We conclude that the keystone flap including a perforator is a reliable option to reconstruct trochanteric pressure sores.

Ipsilateral tonsillectomy and panendoscopy-guided biopsy following imaging studies are considered a standard procedure in the search for a primary origin in patients with cervical metastatic carcinoma of unknown origin(MUO). However, many authors recommended bilateral tonsillectomy for the determination of the primary site of a MUO, because cervical metastasis may occur contralateral to tonsillar carcinoma. The authors attempted to address the clinical implications of using routine bilateral tonsillectomy to determine the primary site of MUOs based on a case report of cervical MUO that was finally diagnosed as a bilateral synchronous tonsillar carcinoma with cervical metastasis after a diagnostic work-up that included bilateral tonsillectomy.

Ankylosed tooth is defined as 'the discontinuance of normal passive tooth eruption without any mechanical barrier'. Ankylosed tooth treatment is a challenge to dental clinicians. In treatment of maxillary molar ankylosis cases there are risks of oro-antral fistula, displacement of root fragments into the maxillary sinus, as well as the necessity for providing additional sinus bone augmentation for future implant placement. In this study, we suggested a new technique using a piezoelectric device and a lateral side approach to the maxillary sinus leading to the simultaneous removal of the ankylosed maxillary molar and sinus grafting for the purpose of implant site development.

Objectives: A 74-year-old male patient with unresectable advanced gastric cancer (clinical initial stage T3N+, Borrmann type III) admitted due to gastric bleeding at tumor site. On first admission day, hemoglobin level was 5.7g/dl and performance status was grade 3 according to Eastern Cooperative Oncology Group Performance Status(ECOG-PS). After performing red blood cell transfusion as an emergency treatment, hemoglobin level was increased up to 9.5g/dl. However, bleeding of oozing site was continued. For hemostasis, decoction of notoginseng radix (30g/day) was administered since day 7 after admission. The dose was elevated to 40g/day after hemoglobin level was decreased to 6.5g/dl on day 11. Since then, melena was stopped and hemoglobin level was maintained over 9.1g/dl. This case shows the hemostasis effect of decoction of notoginseng radix on gastric bleeding in unresectable advanced gastric cancer.
