This is a case report of total sternal resection and successful reconstruction of the sternum applying Tantalum plate in multiple myeloma. The patient was a 57 year old male with a tumor located on the middle sternum invading the manubrium and the body of the sternum developing symptoms after a contusion of the anterior sternum. The sternum resected with left and right. from first to sixth costochondral cartilages, and then Tantalum plate was fixed to the all fragments of the ribs with wire sutures. After reconstruction of the sternum applying Tantalum plate, the patient has had good breathing movements of the chest wall and also maintenance of respiratory function was satisfactory. Histopathologically, the tumor was consisted of a tissue of plasma cells, which was identical to multiple myeloma. Postoperative chemotherapy with Endoxan for multiple myeloma was administered. No recurrent symptoms of multiple myeloma could be observed during one year follow up period.

Pancoast syndrome (PS) is characterized by a malignant neoplasm of the superior sulcus of the lung with destructive lesions of the thoracic inlet and involvement of the brachial plexus and cervical sympathetic nerves. The most common initial symptom of PS is shoulder pain; however, cough, dyspnea, and hemoptysis, signs often associated with lung cancer, are not as common. Investigation of PS can be difficult even with plain radiographs of the chest because it is surrounded by osseous structures such as the ribs, vertebral bodies, and manubrium. Due to these characteristics, orthopedic surgeons tend to make a misdiagnosis resulting in delay of appropriate treatment. Here we report on a patient who was supposed to undergo rotator cuff repair for his shoulder pain and weakness, and was eventually diagnosed with PS.

We have experienced a case of occult papillary thyroid carcinoma presenting as an anterior mediastinal mass in a 40-year-old man. The CT scan revealed a huge mass behind the manubrium of the sternum but the ultrasound examination failed to detect any lesion and developmental defect in the thyroid. Excision of the mediastinal mass and total thyroidectomy were carried out. Histologically, the mediastinal mass turned out to be papillary carcinoma without any portion of the normal thyroid tissue or normal lymph node tissue and the thyroid gland showed a tiny papillary carcinoma with the diameter of 0.3cm. Although a mediastinal mass as the sole presentation of the thyroid carcinoma is very rare, we suggest that a mediastinal mass should be added to the list of possible metastatic thyroid carcinoma.

65세 남자 환자가 우측 흉늑쇄골부위의 동통성 부종을 주소로 내원하였다. 환자는 과거력과 외상을 비롯한 특이 소견은 없었다. 입원 후 시행한 컴퓨터 단층촬영에서 우측경부의 농양과 우측 농흉소견이 나타났다. 개흉술로 우측 농흉제거술을 실시하였으며 우측 벽측 흉막과 우측 흉늑쇄골부위에 루가 발견되었다. 이어 경부절개를 통해 경부농양을 제거하였고 우측 흉늑쇄골부위에 골수염의 소견이 있어 우측쇄골일부, 제1번 늑연골, 흉골병 일부를 같이 제거하였다. 우측 흉늑쇄골부위의 골수염이 농흉으로 확대된 예는 드문 경우로서 저자들은 이를 치험 하였기에 보고하는 바이다.

A new and a unique Brachionus rotifer was found in Hwajinpo coastal lagoon in Gangwon Province, South Korea. This Brachionus certainly originated from the wild rather than from aquaculture stations because Hwajinpo coastal lagoon has been under rigorous control as a military protected area and therefore could not have been contaminated by aquaculture stations. The new strain was identified as Brachionus rotundiformis based upon its morphological characteristics. The parthenogenetic female of this new rotifer strain typically shows characters similar to those of B. rotundiformis, such as the pot shape of the body, rounded dorsal plate compared with flattened ventral plate, elliptical mictic egg, four frontal spines, six pointed occipital spines, non-nodal foot, two toes, trophi typical of the Brachionus genus with five uncus plates resembling comb teeth, one wide symmetrical manubrium and ramus, and no stiffened spine as is seen in freshwater Brachionus rotifers. Moreover, its lorica was rather small in size compared with other common rotifer strains that serve as live-food organisms (Guam, Thai, and Bali strains). This new and unique Korean brackish rotifer, a B. rotundiformis strain, was therefore named the National Fisheries Research and Development Institute (NFRDI) $N^{\circ}1$ rotifer strain.

This is a report of 3 cases of tumors, which primarily originated from ribs and the sternum. In the first case of multiple myeloma, the patient was 67 year old male with a tumor located on the middle sternum invading the manubrium and the body of the sternum manifesting symptoms after a contusion of the anterior sternum. The sternum was entirely resected and was replaced by tantalum plate to reconstruct the defective chest wall in order to prevent the paradoxical movement during respiration. In the second case of osteogenic sarcoma, the patient was 43 year old male with a tumor located on the costochondral junction of the left 5th rib for 6 months. The left 5th rib was resected between the middle part and sternochondral junction of it including tumor and adjacent soft tissues. In the third case of chondrosarcoma, the patient was 36 year old male with a tumor located near the posterior angles of the right 7th and 8th ribs manifesting back pain on the area where the tumor was located. Resection of right lower lobe was performed since direct invasion of tumor was seen in the superior segment of right lower lobe. This was followed by the resection of both 7th and 8th ribs at the area between the costovertebral junction and the portion 10 em apart from the tumor including the tumor and intercostal soft tissues. Diagnoses of 3 cases of tumors described above were confirmed by histopathologic examination postoperatively. The postoperative courses were uneventful.

The anterior mediastinal tracheotomy(AMT) facilitates resection of stomal recurrence after total laryngectomy and tumors involving the cervicothoracic trachea and esophagus. An 81-year-old-man came to our clinic due to the progressive dyspnea during three months. He received the total laryngectomy five years ago. We diagnosed as Sisson type I stomal recurrence and then performed the wide excision, both selective neck dissection, sternal manubrium resection and AMT. Before surgery, we planned the pectoralis major myocutaneous flap. Unluckily we could not fulfill this procedure because of patient's medical status during anesthesia. The tracheocutaneous fistula was observed in the second postoperative day. He expired due to the huge bleeding from the wound. When AMT is performed, exact manipulation of major vessels and adequate flap are mandatory these elevate the feasibility of AMT.

A 65-year-old male visited hospital in the state of tracheostomal recurrence 1 year after total pharyngolaryngectomy. Extensive recurrence around stoma or paratracheal, superior mediastinal area is challenging in treatment, especially in securing airway. We performed mediastinal tracheotomy through resection of unilateral manubrium, some part of sternal side of clavicle and $1^{st}$ rib as the salvage operation for recurrent laryngeal cancer. This procedure could be risky, thus very careful patient selection is required because of a tortuous postoperative course. We would like to present the case that anterior mediastinal tracheostomy could be needed as appropriate palliative means of airway construction in the patients with recurrent laryngeal cancer with lower neck extension with literature review.

흉부 대동맥의 외상성 파열은 두부 손상 다음으로 흔한 교통사고의 사망원인으로 약 85%의 환자가 병원 도착 전에 사망한다. 가장 흔한 기전은 고속의 차량이 충돌 등으로 인한 급작스런 감속에 의해 발생되며 대동맥 협부가 전체 대동맥 손상의 95%에 해당된다. 또 다른 기전으로는 흉부 압박 손상에 의해 골절되어 전위된 흉골병과 흉부 척추 사이에 대동맥이 끼이면서 나타날 수 있는데 이로 인해 흔하지 않은 위치의 대동맥벽의 내막이 파열된다. 저자들은 감속사고가 아닌 흉부 압박에 의해 대동맥궁이 파열되어 박리된 증례에 대해 집중적인 내과 치료 후에 지연 수술로 완전 순환정지 하에 뇌보호를 시행하면서 상행 대동맥의 일부와 대동맥궁을 인조혈관으로 치환하였기에 보고하는 바이다.
