Papillary thyroid carcinoma is rarely associated with macroscopic vascular invasion or tumor thrombosis. Especially, superior vena cava syndrome(SVCS) resulted from tumor thrombosis of papillary thyroid carcinoma is extremely rare. We present herein a case of SVCS caused by tumor thrombosis from papillary thyroid carcinoma which was successfully solved by intravascular placement of self-expandable stent in 74-year-old woman.

Papillary thyroid carcinoma is known as its relatively high cure rate after surgical treatment. But invasion of the trachea by thyroid carcinoma is poor prognostic factor and the best management is en bloc surgical resection of the tumor invading the trachea. A 55-year-old man was diagnosed as papillary thyroid cancer with tracheal invasion. We treated the patient by total thyroidectomy with window resection of invading trachea followed by immediate reconstruction with sternohyoid muscle flap and tracheostomy. At 48 days after surgery, tracheostoma was closed and the patient had no functional complication by the surgical process. Until 10 months after surgery, there was no sign of recurrence and the patient led social life without any discomfort. We present this case with a review of the related literatures.

Background and Objectives : In the TNM 6th classification system, extrathyroidal invasion of differentiated thyroid carcinoma has been classified into T3(minimal invasion), T4a(extended invasion), and T4b(more extensive unresectable invasion) according to the degree and it has been recognized as an important prognostic factor. In this study, we investigated the prognostic significances of minimal extrathyroidal invasion in papillary thyroid carcinoma(PTC). Material and Methods : We retrospectively studied 221 patients who are underwent thyroidectomy due to PTC from September 2003 to December 2006. Fifty-four(24.4%) patients had a PTC with minimal extrathyroidal invasion(Group A) and 167(75.6%) patients had a PTC without extrathyroidal invasion(Group B). The existence of minimal extrathyroidal invasion was based on operative and pathological findings. Results : Minimal extrathyroidal invasion in PTC was related to tumor size, lymph node metastasis, and operative method(p<0.001). But, there is no significant difference in age, gender, and multifocality between Group A and B. Hashimoto's thyroiditis was observed more frequently in Group B(p=0.019). Conclusion : These findings suggest that minimal extrathyroidal invasion is related to poor prognostic factors in PTC. Therefore, aggressive surgical approach is required when there is evidence of minimal extrathyroidal invasion in preoperative radiologic examination or operative finding.

Purpose：The chronic use of immunosuppressive therapy in transplant recipients can increase the long-term risk of carcinoma. The aim of this study was to determine the incidence, biological behaviors, and treatment outcomes in PTC(papillary thyroid carcinoma) in renal allograft recipients. Material and Methods：The present study examined the incidence and biological behavior of PTCs in RA recipients. A total of 1,739 RA patients treated between January 1986 and December 1999 were followed-up for a median 137(84-238) months. During the follow-up period, 129(7.4%) recipients were identified as having posttransplant malignancies. Of those, 12(0.7%) had PTCs, and these comprised six male and six female patients with a median age of 41(23-57) years. Results：Nine cases(incidentalomas) were diagnosed based on ultrasonography(US) screening. Eight of those nine were TNM stage I, and two of the three clinical carcinomas were TNM stage IVa. During a median follow-up of 94(18-159) months, two(16.7%) PTC patients developed loco-regional recurrence, but no patients showed distant metastasis. Posttransplant PTC showed no gender bias, and was often associated with aggressive lymphatic metastasis. However, most incidentalomas showed a favorable treatment outcome. Conclusion：In conclusion, routine surveillance of the thyroid gland using US screening is recommended to ensure early detection, treatment and favorable prognosis in RA patients with PTC.

1983년 1월 부터 1987년 12월까지 5년간 부산의 세곳 대학병원(부산의대, 고신의대, 인제의대)에서 병리조직학적으로 확진된 갑상선암 629예중 병력지 관찰이 가능하였던, 478예를 분석하여 1988년 보사부에서 발행한 Five Years' Report for Cancer Registry Programmme in Republic of Korea (1982 7. 1$\sim$1987. 6.30)의 발생빈도와 비교하였으며, 478예중 311예의 갑상선주사 소견을 분류하여 다음과 같은 결과를 얻었다. 1) 전체 악성암에 대한 갑상선암의 발생빈도는 2.54%(629/24.749)이었으며 이는 한국인에 있어서의 발생빈도와 거의 같았다(2.5%). 2) 여자에서 5배 이상 발생하여 (1 : 5.64) 이것 역시 한국인에서의 성별빈도와 매우 유사하였다(1 : 5.22). 3) 연령분포는 10세에서 91세까지로서 87.03%가 20세에서 59세 사이에 있었다. 4) 유두상암이 가장 흔하였고(78.24%),다음이 여포상암(14.44%) 그 다음이 미분화암(22.30%) 이었다. 5) 갑상선주사 소견상 대부분의 암은 solitary cold nodule을 보였다(82.96% : 258/311).
