We report a 10-year-old girl with the blue rubber bleb nevus syndrome (BRBNS) who had chronic severe anemia caused by chronic occult bleeding in the gastrointestinal (GI) tract. The patient was admitted to the hospital frequently for recurrent pallor and fatigue since the age of 7 years. Gastroduodenoscopy and capsule endoscopy revealed multiple venous malformations with blood oozing in the stomach, small bowel and colon. The patient was treated by aggressive surgical resection of the 23 vascular malformations in the GI tract. The patient is well without anemia 15 months post surgery.

A 20 year old woman had developed stenosis at the lower part of the trachea, right main bronchus, and right upper lobe bronchus as a complication of endobronchial tuberculosis. The patient had complained of severe dyspnea. Tracheobronchial stenosis was so extensive that we did reconstruction of the trachea and right bronchus with resection of the lower trachea and right main bronchus and right upper lobectomy. She has been doing well without any respiratory symptoms or complications.

Tuberculosis infection is wide spread disease and makes troublesome complications in some cases. A 50 - year old male visited Andong Hospital with coughing and sputum, dyspnea on exertion, bulging left anterior chest wall mass. Chest X-ray showed right pleural effusion, both side streaky infiltraion, and pleural thickness in apex. Chest CT scan showed bone destruction of left clavicle head, manubrium and large abscess pocket in pectoralis muscle. In May 1996 he underwent en bloc resection of left upper anterior chest wall including pectoralis major and minor muscle, left clavicle head, manubrium and covering infected skin, then contralateral pectoralis major muscle flap and skin graft was done. Patient shows no evidence of recurrence during follow up.

The melanotic neuroectodermal tumor of infancy(MNTI) is a rare childhood neoplasm with a clinical presentation. Because of its rapid growth pattern and bone resorption, the lesion can be mistaken for a malignant neoplasm. Although an aggressive growth rate and radiographic appearance, the MNTI almost always behaves in a benign fashion and can be treated with total excision. We presented the MNTI occured in the left maxillary alveolar ridge of 5 month old female infant. showing bluish enlargenent of alveolar mucosa with the displacement of central decidious incisor. And after the surgical excision of the mass, there is no recurrent tendency.

We reported a case of chondrosarcoma in proximal tibia in a 44-year-old man. MR images demonstrated a $3.5{\times}20$ cm sized bone tumor. In reconstruction of resected proximal tibia, we used the allograft bone and soft tissue defects were covered by medial gastrocnemius rotation flap and skin graft. There were no local recurrence and distant metastasis and any complication such as secondary infection, nonunion, metal failure at the time of the last follow-up. There was no limitation of knee motion through the appropriate rehabilitaion programs.

In 1996, a nine-year-old girl was treated with recycling autograft after wide resection of the distal femoral osteosarcoma. The leg lengthening and revision with growing tumor prosthesis were performed due to limb leg discrepancy and epiphyseal problem. However, deep infection developed after operation, and a temporary spacer with cement and Ender nail was inserted. After infection was controlled completely, the final leg lengthening was performed with mono-external fixator for limb length discrepancy (10 cm). Lastly, Tumor prosthesis was reinserted to preserve the joint function.

The soft palate of carcinoma limited to the uvular region is infrequent among oropharyngeal cancers. The oropharynx regulates swallowing and speech through dynamic motions. Failure to reconstruct after surgical resection of the oropharynx structure can lead to permanent velopharyngeal insufficiency. Therefore, suitable reconstruction is important in establishing proper functional outcomes while maintaining oncological safety. We present a case of a 66-year-old male who was diagnosed with oropharynx cancer limited in the uvula accompanied by lymph node metastasis. After surgical resection, reconstruction was performed with the united arrangement of bilateral palatal mucomuscular flap and superiorly based posterior pharyngeal flap. There was no aspiration or reflux after feeding and epithelialization completely occurred after 1 month postoperatively. We report a successful case that the reconstruction with the local flap described above could preserve proper oropharyngeal function after primary surgery in small-sized oropharyngeal cancer.

Adult fibrosarcoma is a malignant tumor comprising of spindle-shaped fibroblasts with variable collagen production. Due to their aggressive nature and high probability of local tumor recurrence, these tumors require accurate diagnosis and resection according to guidelines. A 57-year-old male presented to the clinic with a complaint of a palpable growing mass in the left scapular area. Examination of the back revealed a 6 cm protruding tumor with a nodular surface. We performed a wide excision, including the infraspinatus fascia layer and subsequent reconstruction using a parascapular island flap. Histopathological analysis demonstrated the typical microscopic features of adult fibrosarcoma. At the 3-year follow-up, there was no evidence of local recurrence and the resection margin was completely clear of tumor.

Parosteal lipoma is a rare tumor that occurs very close to the bone, and accounts for approximately 0.3% of all lipomas. Chondrolipoma, a lipoma with cartilaginous metaplasia, is also a rare tumor consisting of mature adipose and cartilage tissues. Therefore, a tumor with characteristics of both parosteal lipoma and chondrolipoma simultaneously is extremely rare. Herein, we report the imaging findings of a parosteal chondrolipoma arising in the right periscapular area, confirmed based on surgical resection and histopathologic examination.

Purpose: To analyze clinical, radiological and pathological features as well as clinical outcome after surgical treatment of patients with secondary chondrosarcoma arising from osteochondroma(tosis). Materials and Methods: We retrospectively reviewed clinical records, radiographs, pathologic slides of 14 patients. Nine patients were male and fi ve were female. The mean age was 34 years. The mean follow-up period was 54 months. Results: All patients had a history of previous mass since childhood or puberty. Preexisted osteochondroma was single in 3 patients and multiple in 10. Remaining 1 patient had multiple osteochondromatosis with enchondromatosis. MRI clearly provided thickness of cartilage cap, which was over 2 cm except in 2 cases. Chondrosarcoma was grade 1 in all except 1 case, which was grade 2. Wide excision was performed in 10 patients, marginal excision in 3 and amputation in 1. Twelve patients were doing very well without evidence of disease. Among 3 patients with marginal excision, 1 patient had local recurrence and 1 patient died of disease. Conclusion: Comprehensive understanding of clinical, radiological and pathological features of secondary chondro sarcoma is warranted for accurate diagnosis. The best result can be expected with early recognition of malignant change of osteohcondroma(tosis) and wide excision.
