Pulmonary sequestration is a very rare congenital malfomation, especially when it is located in the infradiaphragmatic retroperitoneal space. The patient was a 56-year-old man with no respiratory symptom but had some postprandial epigastric discomfort for several days. Plain chest x-ray revealed mild elevation of left diaphragm and abdominal CT scan showed large cystic retroperitoneal mass with some calcification. We performed the operation through the thorachoabdominal incision and the mass was proven to be a pulmonary sequestration. Therefore, we report the case with review of literatures.

Purpose: To analyse the risk factors for recurrence of hemangiomas in extremities after surgical treatment and to compare with those of trunk. Materials and Methods: 120 cases of hemangioma with surgical treatments from June 1998 to September 2009 were analysed. 53 cases with surgical treatment on trunk in the same period were set to be the control group. We analyze several factors: age, location, site, size, histologic types and correlation between recurrence and each risk factor using logistic regression analysis. Results: Recurrence rate was 11.7% in extremities and 9.4% in trunk. There were no correlation between recurrence and age, site, size, histologic type. But, there was stastically significant correlation between recurrence rate and location, especially hand, forearm, feet in extremities and head and neck in trunk. Conclusion: Recurrence after surgical treatment of hemangioma is highly prevalent in anatomical location such as, hand, foot and forearm those are difficult to achieve complete resection because of close to neurovascular structures. Careful observation should be needed owing to incomplete resection can occurs recurrence.

Glomus tumor is a kind of vascular tumor that arises from the glomus body, which regulates skin temperature and is placed in the skin and the subcutaneous area. It is a benign tumor that usually presents in the subungal area. It is relatively common in areas other than the fingers, but its occurrence in peripheral nerves is known to be comparatively rare. We report our experience with a case of glomus tumor arising from the brachial plexus, a rare site of occurrence for glomus tumors.

Osteochodromas are the most common benign osseous neoplasm, covered by a distinct hyaline cartilage cap, originating from the physis. They involve typically metaphyseal or metadiaphyseal region of a long bone, while they involve the foot rarely. In the foot, the osteochondromas mostly occur in short tubular bones such as metatarsal bones and phalanges. They are seldom found in calcaneus. We report a rare case of osteochondroma involving calcaneus.

Angiomatoid fibrous histiocytoma is a rare soft tissue tumor that generally affects children and young adults. We report a case of angiomatoid fibrous histiocytoma in an 11-year-old boy who complained of a back mass for 3 years. Surgical excision was performed. The excised specimen showed a $4.0{\times}3.6{\times}3.0cm$, well circumscribed, grayish white tumor, with multicystic changes. Histological examination showed proliferation of spindle or round shaped tumor cells. There was a dense fibrous pseudocapsule with prominent chronic inflammatory cell infiltrates.

Hibernoma is a rare, benign soft tissue tumor that is derived from the remnants of fetal brown tissue. The term hibernoma was proposed in 1914 by Cery because of its morphologic similarity to the cel s of the so-called hibernating gland of animals. The most common site of hibernomas is the subcutaneous tissue of the back, especially the interscapular area. These tumors are considered benign and malignant transformation has not been reported. We experienced a case of hibernoma, 60-year-old woman had suffered from the palpable mass without pain or tenderness on posterolateral lower chest wall, left. The tumor was extirpated under the impression of angiolipoma, but was confirmed hibernoma. She was discharged without complication.

Purpose : The giant cell tumor of tendon sheath is the second most common tumor of the hand, but recurred frequently although excision was performed. Authors analyzed and would report clinical findings and postoperative results of it. Materials and Methods : Between January 1991 and December 1998, 38 patients, 41 cases which the authors had performed excisional biopsy to the mass in the hand and diagnosed with the giant cell tumor of tendon sheath, was analyzed with age, sex, chief complaint, symptom duration, involved finger, involved tendon, frequently developed site in fingers, size, multiplicity, radiologic findings and recurrence. The mean duration of follow-up was 13.1 months (5~40 months). Results : Of 38 patients, twenty-nine were female. It is frequent in the fourth decade and mean age was 40.1 years old. The neurological compression symptom was found in 5 cases. The mean duration of symptom was 23.4 months. Flexor tendon was involved in 24 cases. The distal interphalangeal joint area in digit was involved most frequently in 20 cases. Index finger was the most common involved finger (14 cases), and long finger was the second most common (9 cases). All tumors were unilateral. The majority of patients had solitary lesion but one case had multiple lesion. In the radiologic findings, erosion or pressure indentation of bone was seen in 3 cases. All patients were operated by marginal excision. Recurrence rate was 5.1%. Conclusion : The risk factors in giant cell tumor of tendon sheath were female, forth decade, index finger, flexor tendon, and distal interphalangeal joint area. The recurrence was increased in marginal excision of recurred cases, in cases with multiple developed lesions or in multilobular lesion, so wide surgical excision is necessary to prevent recurrence.

The author has arrived at the following result after having carried out multilateral study based on a total of 282 maxillofacial fracture patients who have receive treatment at the Euijeongbu general hospital and Shinchun general hospital in the northern district of Kyunggido from march 1988 to august 1990. 1. Sex distribution of Mx. facial fx. patient was higher in male by 4.6:1 and was predominant in the 3rd decade with 40.4% followed in decreasing order by the 2nd decade and the 4th. 2. A majority were in the Mn. with 40.2% followed in decreasing order by zygoma. nasal bone and maxilla. 3. For the sex distribution according to anatomy, make to female ratio was 6.2:1 in the mandible, followed in decreasing order by zygoma, and nasal bone with predominance in male. 4. Car accident with 42.8% was the most common cause of fx. followed in decreasing order by violence, workmen's accident, and fall down. 5. The involvement of other trauma areas are head. 79.0%, abdomen-thorax, and the extremities in decreasing order. 6. In the mandibular fx. a majority were in the symphysis with 73.9% followed in decreasing order by angle, Condyle, and body. 7. Maxillary fx. of the type LeFort II was estimated to be 41.2% 8. Fracture in the zygoma including zygomatic arch was estimated to be 72.5%

This is clinicostatistical study of mandibular fractures. This study was based on a series of 677 patients with mandibular fracture during the period of 1982 to 1987. This results obtained were as follows : 1. In respect of incidence, there were high frequency in May and September, and in large city(63%). 2. The age frequency was the highest in the 20s-year old group (38.7%), and the ratio of male to female was 4.64 : 1. 3. The most common etiologic factor was blow(31.5%), but in children that was traffic accident followed by fall down. 4. The most common site of bone fractures was symphysis, followed by angle, condyle. In comparison of right and left sides, left side was more frequently involved(364 cases) than right side(257 cases). 5. The patients arrived in hospital immediately within 24 hours after accident were 62.9% of all, and 42.4% was arrived via private medical and dental clinic. 6. In respect of treatment, open reduction was 55.5% of all, closed reduction was 37.2%. In children, closed reduction was done in 50.6%.
