The purpose of this study is to introduce a new method for fingertip coverage for cases of soft tissue only defects and finger tip amputations including bone. 86 lingers in 67 patients haute undergone coverage with a large rotation flap based on digital artery and nerve and Z-plashy after fingertip amputation or finger pulp avulsion from October 1991 to December 1995. There were 53 thumbs, 12 index fingers, 5 long fingers, 3 ring fingers and 13 little fingers. All injured fingers had exposure of the distal phalanx bone. A large volar flap based on either the radial or ulnar aspect including both digital neurovascular bundles was elevated just abode the pulleys and flexor tendon sheath after longitudinal incision along the lateral border of the digit. Then a large Z-plasty was performed at the MP joint crease to release the tension. The volar flap was easily rotated to cover the fingertip and was sutured with slight flexion of the interphalangeal joints. All fingertip defects healed completely. These flaps successfully covered the fingertip, and up 2/3 of the distal phalanx on the volar or lateral aspect. Sensation returned to normal and fingers could be fully extended within 3 months of surgery. All patients only required a single operation for complete fingertip coverage and did not require bony shortening. We conclude that this large rotation, axial pattern, neurovascular flap and Z-plasty provided a durable, completely sensate, well vascularized coverage fort the fingertip with minimal discomfort for the patient.

The area overlying the ischium is the most frequent site for the development and recurrence of pressure sores in the paraplegic patient. This report describes a newly-designed inferior gluteus maximus myocutaneous island flap that is useful for the repair of ischial pressure sores in paraplegic patients. Sacral sore develops a wide and flat ulcer crater. However, ischial sore seems to develop large and deep bursa with relatively small openings. We have used a newly-designed gluteus maximus myocutaneous island flap according to the specific characteristics of ischial sore. The flap is designed in the fashion of a small skin island with a large muscle flap. This flap with its abundant and constant blood supply had proved very reliable in the surgical management of ischial pressure sore. There is also the possible advantage of cushioning with the bulk of muscle for greater long-term durability. Incision could be extended for a complete bursetomy and partial ischiectomy. The reliability, versatility and low morbidity of the inferior gluteus maximus island flap has been demonstrated by its use in our consecutive series of 7 patients with 8 ischial pressure sores. We conclude that this newly-designed inferior gluteus maximus myocutaneous island flap can be applied in deep, infected ischial sore according to the specific characteristics of ischial sore, and it is a very useful method in comparison to other flaps.

Gestational trophoblastic disease associated with the tubal pregnancy is uncommon, and the incidence has been described as 1/5000 tubal pregnancy. We have experienced a case of metastatic gestational trophoblastic disease(GTD) in the lung occuring with complete hydatidiform mole arising in tubal pregnancy. The patient was a 39-year-old, G4P2A2L2 woman with amenorrhea for 5 weeks. Ectopic pregnancy in the right fallopian tube was suspected on transvaginal ultrasonogram. A right adnexectomy was performed. The fallopian tube was markedly dilated and ruptured. The right ovary and a round hematoma had adhered to the external surface of the fallopian tube. On gross examination, no molar tissue was identified. On microscopic examination, the lumen of the dilated fallopian tube was filled with blood clots admixed with several chorionic villi showing hydropic swelling and marked proliferation of atypical trophoblasts. Proliferating syncytio-and cytotrophoblasts invaded the wall of the blood vessels of the fallopian tube and sheets of trophoblasts and some villi were identified in the lumen of blood vessels. Multiple pulmonary nodules thought to be metastatic nodules were identified in the chest X-ray and serum beta-HCG had increased 2 weeks later. This case indicates that a careful pathological examination in the ectopic pregnancy is mandatory, because tubal GTD is not clinically distinguishable from ordinary tubal pregnancy.

BACKGROUND: Becker's mealanosis is not an uncommon entity, and many cases are probably not reported because the diagnosis is usually made clinically and the condition is benign with cosmetic significance only. the etiology remains obscure. OBJECTIVE: The purpose of this study is to establish the clinicopathologic characteristics of Becker's melanosis in Korean. METHODS: Thirty-six patients with Becker's melanosis were retrospectively studied. RESULTS: The clinical and histopathologic findings observed in our cases were similar to previous reports except for the following. Nine patients(25%) had abnormal findings in their hair follicles : dilatation of the infundibular portion filled with abnormal keratin, Pityrosporum orbiculare and bacteria(19.4%); formation of intrafollicular cyst(5.6%). Three patients(8.3%) had granulomatous infiltration. Twenty-two patients(61.1%) had increased smooth muscle bundles. CONCLUSION: The findings associated with dermal hair follicles may be related to the pathogenesis of Becker's melanosis.

Breast cancer is the second leading cause of cancer death in women. Unfortunately, the frequency of breast cancer and mastectomy are increasing in Korea. The purpose of the study is to analyze the results of breast reconstruction using free transverse rectus abdominis myocutaneous(TRAM) flap and to suggest the operative technique for more satisfactory results. 19 patients underwent immediate breast reconstruction from 1990 to 1998, and we experienced 2 cases of bilateral immediate reconstruction of breasts following mastectomy. We have performed the free TRAM flaps based on the deep inferior epigastric vessels using microvascular technique. TRAM flap included very small portion of rectus sheath and muscle-so called muscle sparing technique. So it reduced markedly donor site morbidity. The postoperative course of these cases was uneventful with minor complication. The free TRAM flap was an excellent method of immediate breast reconstruction using autogenous tissue and provided satisfactory outcome. The goals of the immediate breast reconstruction after mastectomy are to restore body image, to achieve near normal shape of breast, and to reduce the complications. This paper represents our experience of immediate breast reconstruction using free TRAM flap, and technical options to get more satisfactory result and reduce the complications. We think this method could be regarded as the first choice for immediate breast reconstruction.

Microsurgical reconstruction is necessary for children to correct severe trauma and congenital or acuqired deformity. The aim of this study was to evaluate whether or not microsurgical reconstruction is a safe and reliable operation in children and to analyze the differences of microsurgical reconstruction in children compared to adults. The study included 12 children who underwent 13 microsurgical reconstructions among a total of 251 cases of microsurgical reconstruction from May, 1986 to August, 1998. Their ages ranged from 24 months to 14 years and 8 months. There were 7 males and 6 females. The involved sites were 9 legs, 3 hands and 1 face. The causes of microsurgical reconstruction were 9 traumas, 2 congenital anomalies, 1 acquired deformity and 1 cancer. The applied flaps were 4 scapular flaps, 2 rectus abdominis muscle flaps, 1 de-epithelized groin flap, 1 lateral arm flap, 1 forearm tendocutaneous flap, 1 forearm tendocutaneous flap, 1 latissimus dorsi muscle flap, 1 fibula flap, 1 second toe transfer, and 1 wrap-around flap. All patients have had normal growth of the donor and recipient sites without specific complications during an average 2 years follow-up. We concluded that microvascular reconstruction is a very useful and reliable procedure in children if it is performed in consideration of each child's specific characteristics and conditions.

Journal of the Korean Society of Plastic and Reconstructive Surgeons 1998;25(8):1491-1500
There is room for debate in appropriate diagnosis and treatment due to physiological and anatomical differences in pediatric facial bone fractures from that of adult's. The objectives of this article is to analyze for our clinical cases and to suggest the appropriate management of facial bone fracture in children. The study included 56 children who had treatment for the craniofacial fractures form March, 1990 to February, 1998. Their ages ranged from 3 to 15. There were 38 males and 18 females. Physical examination, simple x-rays, ultrasonograms and routine CT scans were used for diagnosis. Materials were classified into 28 nasal bone fractures, 4 nasoethmoidal fractures, 6 orbital fractures, 8 mandible fractures, and 10 zygoma fractures. Patients were treated with conservative treatment in 9 cases, with closed reduction in 28 cases and open reduction only, and 14 patients with open reduction and internal fixation using microplates and screws. 3 patients needed autogenous calvarial bone graft. Plates and screws were removed in postoperative 3-6 months. All patients had successful union of fractured bones without no specific complications, and normal bony growths were noticed during the 7 years follow up. We conclude that surgeons should be careful in diagnosis and management for the pediatric facial fracture due to anatomical variations and differences in fracture aspects. First, it is mandatory for surgeous to get accurate diagnosis and identify children's fracture and displacement through routine CT check up along with physical examination. Second, it is important to perform the minimally invasive technique or conservative treatment for the children with mild displacement so that it reduces the incidence of growth retardation which may be caused by extensive operation. However, application of rigid fixation is necessary in case of extensive bony displacement or bony defects because of poor coorporation in postoperative care. Third, plates and screws which were used for the internal fixation should be removed at 3-6 months after the surgery. Fourth, if bone graft is needed, it is better to use autogenous graft than allogeneous graft. Fifth, care for dentition and follow up for growth are necessary for growing children.

Hemifacial microsomia is a common congenital craniofacial deformity involving bone and soft-tissue. Mandibular hypoplasia is the most obvious skeletal manifestation of hemifacial microsomia. In the past, complete realignment of the skeleton was preferred to soft-tissue correction, which was clearly second choice. However, in this study, simultaneous correction of bone and soft tissue deformities were equally important in treatment of hemifacial microsomia. One-stage and simultaneous bone and soft tissue reconstruction is possible and staged operations of the skeleton and soft tissue are no longer necessary, except in special cases. Even in children and adolescents, good results and normal growth potential can be achieved with simultaneous correction of bone and soft tissue.

It is well known that the medullary carcinoma of the breast is one of the special types of breast carcinoma with a good prognosis. At present, the medullary carcinoma of the breast is subclassified into 3 types: typical medullary, atypical medullary and nonmedullary carcinoma. Among them, the former has the best prognosis. We reviewed the film mammographic and ultrasonomammographic findings of 13 patients according to the reevaluated histopathologic diagnosis. Typical medullary carcinoma shows a well circumscribed mass with surrounding halo on film mammogram, and well defined mass with central intermediate echogenicity and peripheral low echogenicity and posterior acoustic enhancement on ultrasonomammogram. Atypical medullary carcinoma shows relatively well circumscribed mass with partial marginal obliteration on film mammogram, and irregular bordered mass with inhomogeneous echogenicity due to focal necrosis in the mass and associated findings of thick boundary, asymetrical lateral shadowing on ultrasonomammogram. Nonmedullary carcinoma shows lobulated mass with surrounding parenchymal distortion and skin thickening on film mammogram, and relatively well defined lobulating mass with surrounding parenchymal distortion and marked heterogeneous internal echogenicity on ultrasonomammogram. Therefore, differentiation between typical medullary carcinoma with good prognosis and atypical medulary or nonmedullary carcinoma with poor prognosis, may be possible by various diagnostic imaging modalities preoperatively. But further collective study shall be needed in near future.
