The most common cause of treatment failure in oral cavity cancer is when it is found to have local recurrence, usually occurring in the ipsilateral cervical lymph node. On the contrary, it is extremely rare to find local recurrence in soft tissue metastasis (STM) in the contralateral neck. Furthermore, lung cancer and malignant lymphoma are most commonly confined to their primary sites. The poor general condition increases the likelihood of STM, which indicates bad prognosis. A 72-year-old man with a hard and fixed mass on the right submandibular space visited our clinic. He had received a wide excision with local flapreconstruction for squamous cell carcinoma in the left corner of lower lip 18 months ago. We performed the wide excision with bilateral selective neck dissection (I-III), and he was finally diagnosed as STM from contralateral lip cancer. We report this unique and rare disease entity with a literature review.

Osseous metaplasia is defined as the formation of lamellar bone inside soft tissue structures where bone normally does not exist. It results from the transformation of non-osseous connective tissue into mature bone. This condition is rare in the oral and maxillofacial region. We report a case of osseous metaplasia of the maxilla, a rare benign tumor in an uncommon region. A 60-year-old male patient visited our clinic complaining of foreign body sensation and asymptomatic swelling on the right palatal side. However, he did not experience pain and reported no local trauma that he could remember. Intra-oral examination revealed an exophytic lesion on the right palatal portion. On computed tomography, there was a round hard-tissue mass approximately 2 cm in diameter on the right palate area. The mass was biopsied and diagnosed as an osseous metaplasia. We review the clinical, radiographic, and histologic features and common causes of osseous metaplasia and report a rare case of osseous metaplasia of the palate.

Accessory cervical thymic tissue has been rarely reported. However, it should be included in the differential diagnosis of neck masses in children, along with branchial anomalies, lymph nodes and other tumors. This lesion occurs along the descending line of the thymus between the angle of mandible and superior mediastinum. A 2-month-old infant presented with an asymptomatic left sided neck mass. MRI revealed a well defined homogeneous mass in the deep lobe of left parotid gland. At operation, an easily identified soft tissue mass was found in the left submandibular area, measuring $3{\times}1.5cm$. It was completely excised. Microscopic examination revealed normal thymic tissue.

피하 조직에 발생하는 연부조직 종괴에는 다양한 병변이 있으며, 연부조직의 낭성 종괴중에서 혈종은 보통 외상과 관련되거나 혈액응고 장애가 있는 경우에 발생하는 경우가 많다. 저자들은 특별한 원인 없이 2개월 전 우연히 발견되고 크기가 서서히 증가하는 좌측 둔부의 종괴를 주소로 내원한 70세 여자환자에서 초음파를 이용하여 혈종으로 진단하고 제거수술을 시행한 증례를 보고하고자 한다.

Myxomas can be divided into two groups: those derived from the facial skeleton, and those derived from external skeletal soft tissue. Soft tissue myxomas of the head and neck are uncommon, with fewer than 50 cases reported. In any form and location, myxoma of parotid gland is rare. We report a case of myxoma arising from the left superficial lobe of the parotid gland with good long-term follow-up after superficial parotidectomy with tumor excision. A 49-year-old man was referred to our department of plastic and reconstructive surgery with a painless palpable mass that had persisted in the left mandible angle region for 2 years. Excision of the facial mass and superficial parotidectomy with facial nerve preservation were performed. The biopsy result was myxoma. Long-term follow-up for 22 months showed favorable results without evidence of recurrence but with temporary facial nerve weakness right after the surgery. Myxoma should be considered as a differential diagnosis when benign tumor of the parotid gland is being considered.

Lipomas are common tumors occuring mostly in the skin and subcutaneous tissue. This tumors are rare in the thorax. They frequently represent on incidental roentgengraphic finding or symptomes depending primarily on their location and size. The patient was 23-month-old male complained of fever and coughing. His chest X-ray and CT scan were revealed soft tissue density featured of pleural mass in the left lower hemithorax. And thoracotomy was performed for accurate diagnosis and treatment. So, experience of parietal pleural lipoma is reported here in.

Soft-tissue chondroma was very rare in incidence and thought to be benign. Recently, we operated upon a 13 year-old female with a chondroma of the middle mediastinum, which was incidentally detected in chest X-ray as mediastinal mass, measured about 10x8x7 cm in size and completely resected via thoracotomy.

A spayed female, 5-year-old, weighing 2.7 kg, domestic short hair cat was referred to Veterinary Medical Teaching Hospital, Seoul National University. The clinical signs of this patient were weight loss, sneezing, respiratory distress, nasal discharge, epistaxis, ocular discharge, left exophthalmos, and left facial edema and deformity. The laboratory tests represented mild leukocytosis. On the skull radiographs, soft tissue density filled nasal cavity with loss of turbinate detail was found. Destructive and lytic changes of the left nasal bone with soft tissue swelling were identified. On the thorax radiographs, there were a tracheobronchial lymph node swelling and a soft tissue round mass in the left caudal lung field. On computed tomographic scan images, asymmetrical destruction of turbinate and nasal septum and increased soft tissue opacity in the nasal cavity were identified. Destruction of the lateral maxillary bone, invasion to the left retrobulbar region, and craniodorsal deviation of the left eye were seen. Also, there was lysis of hard palate and cribriform plate. Invasion to the brain was found. The patient was diagnosed as nasal lymphoma by cytology and histopathology.

Myxoma is a locally invasive neoplasm usually involving the jaw bones, typically occurs between the second and fourth decades. This tumor may comprise 3%-6% of odontogenic tumors. Myxomas of the soft tissue of the face are very rare. We present an unusual case of myxofibroma occurring in a 13-year-old man involving the soft tissue of the face. It congenitally occurred and was a 1 cm sized, ovoid in shape, swelling located on the glabella without any symptoms. An excisional biopsy was performed. A well encapsulated ovoid mass was attached to the corrugator supercilli muscle below the frontalis muscle. It was measured 1.1 × 1 × 0.8 cm and completely excised. Histological examination revealed myxofibroma showing stellate and spinde-shaped cells throughout myxoid ground substance. The unusual features of this case are the site of the tumor, which was localized to the non-tooth bearing area of the mandible and its congenital occurrence history.

목적: 근골격계 종물의 진단에 있어 초음파 유도하 생검의 유용성을 알아보고자 하였다. 대상 및 방법: 2002년 3월부터 2003년 8월 사이에 본원 정형외과를 내원한 환자 중 연부조직 종물을 가지는 환자의 진단을 위하여 조직 생검이 필요하였던 5 5명 환자를 대상으로 하여 전향적인 연구를 하였다. 조직검사는 초음파 유도하에서 조직의 채취 부위에 국소마취하에 시행하였으며 14 gauge 또는 18 gauge의 굵은 바늘을 사용하여 5~6개의 조직을 얻을때까지 시행하였다. 통계적인 분석은 임상적으로 치료가 가능하였던 11명의 환자와 수술적 절제 후 조직의 최종 확인이 가능한 38명을 포함하여 49명을 대상으로 하였다. 결과: 불충분한 조직을 얻은 경우나 조직학적 진단이 불가능한 6명의 환자를 제외하고 정확한 진단은 49명의 환자중 47명의 환자에서 얻을 수 있어 정확도는 96%였고 민감도는 90%, 특이도는 100%였다. 전체 55명의 환자중 89%(49명)에서 조직학적 진단이 가능한 충분한 조직을 얻을 수 있었다. 모든 환자에서 특별한 부작용은 없었다. 결론: 초음파 유도하 생검은 연부 조직 종물의 정확한 위치에 바늘을 위치시킬 수 있어 연부조직 종양의 진단이나 골종양의 진단에서 골외 부분이 있는 경우 시행할 수 있는 안전하면서 유용한 방법이라 생각된다.
