Follicular thyroid cancer(FTC) accounts for about 10-15% of thyroid cancer. Distant metastasis is common, usually to lung, bone and brain. 71-years-old man visited neurosurgery outpatient department. He complained of recent 6kg weight loss, left upper extremity pain with weakness and back pain. The radiologic findings showed multiple bone metastasis including thoracic spine and left scapular resulting from FTC. There was a probable brain metastatic lesion on right temporal fossa. The core biopsy of thyroid and thoracic spine(T11) confirmed metastatic follicular carcinoma. Radioactive iodine therapy and radiotherapy was done following total thyroidectomy. We report a unique case of multiple bone metastasis from follicular carcinoma of thyroid with literature review.

Liposarcoma is a malignant tumor originated from adipose tissue, accounting for 20% of all soft tissue sarco-mas. A 69-year-old man with anterior and posterior neck mass visited to our department and we performed an excisional biopsy in level Ι. Histopathological examination revealed liposarcoma, so we performed wide exci-sion in anterior and posterior neck, and adjuvant radiotherapy. We report a unique case of well-differentiated li-posarcoma on anterior and posterior neck with literature review. To our best knowledge, such case has not been reported earlier in Korea previously.

The anterior approach to the cervical spine surgery is associated with possible complications such as dyspha-gia, hoarseness and granuloma formation etc. Because of orthopedic metallic plates, the increasing or focal up-take pattern may be demonstrated in 18F-FDG PET/CT scan. A 67-year-old-man came to our department, com-plained of dysphagia during the 4 months. He underwent cervical spine surgery three years ago. The CT and MRI findings mimicked typical posterior pharyngeal wall cancer with cervical metastasis. Furthermore, the SUV in 18 F-FDG PET/CT was 10.3. But he was finally diagnosed as a granuloma resulting from the metallic cervical im-plants. The clinical correlation and medical history should be taken into account to avoid false-positive findings in PET/CT and to avoid many erroneous diagnostic pathways.

Warthin’s Tumor is the second most common tomor of the parotid gland after pleomorphic adenoma. It is well known to occur as bilateral and multiple patterns. The incidence of extraparotid Warthin's tumor(EPWT)is about 2.7% to 12%,peri-parotid and upper cervical area are the most common sites. Warthin's tumor with synchronous intraparotid and extraparotid area is extremely rare, only a few cases have been reported. We report a-71-year old man with unilateral swelling of the parotid area and upper neck,pathologically confirmed Warthin's tumor with literature review.

The anterior mediastinal tracheotomy(AMT) facilitates resection of stomal recurrence after total laryngecto-my 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 dis-section, sternal manubrium resection and AMT. Before surgery, we planned the pectoralis major myocutane-ous 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 bleed-ing from the wound. When AMT is performed, exact manipulation of major vessels and adequate flap are mandatory these elevate the feasibility of AMT.
