Lung cancer, breast cancer and lymphoma are the common oncologic causes of malignant pleural effusion, comprising more than the half of the causes. However, an endocrinologic carcinoma associated malignant effusion is very rare. Recently, we encountered a case of papillary thyroid carcinoma causing malignant effusion. An 83-year-old female patient presented with dyspnea due to massive pleural effusion in her left side. The pleural biopsy, pleural fluid cytology and breast needle aspiration biopsy results were consistent with a metastatic papillary thyroid carcinoma. Thyroid ultrasonography showed two thyroid masses, but the patient refused a thyroid biopsy. This case highlights the need for considering the possibility of papillary thyroid carcinoma when the cause of malignant pleural effusion cannot be found because one of the rare clinical manifestations of a papillary thyroid carcinoma can be dyspnea due to malignant effusion.

Thyroid cancer is known as its relatively high cure rate after surgical treatment and spinal metastasis of thyroid cancer is extremely rare as the prevalence is only 2-13%. Spinal metastasis is usually asymptomatic and discovered incidentally in most cases. A 66-year-old man was diagnosed as thyroid papillary cancer with spinal metastasis. We treated the patient by surgery, adjuvant radiotheraphy and radioactive iodine therapy. C6 corpectomy was followed for the residual spinal metastasis by the department of neurosurgery. The patient had no functional complication by the surgical process. At 24 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.

Purpose : To evaluate the role of magnetic resonance imaging (MRI) in the diagnosis of papillary lesions of the breast. Materials and methods : Among 45 papillary lesions diagnosed at ultrasonography-guided core biopsy (USCB), 27 benign papillary lesions in 22 patients who underwent breast MRI were reviewed. The excsional biopsy was performed in 1-10 days after MRI was done. In MRI findings, lesions were considered suspicious if they show irregular, rim enhancement, or linear enhancement in morphologic evaluation, or washout enhancement pattern of delayed phase in dynamic enhancement characteristics. Diffusionweighted images were analyzed according to visibility of lesions. MRI findings were correlated with pathologic results at excisional biopsy. Results : At excisional biopsy, two lesions (9%) were diagnosed malignant in 22 benign papillary lesions without atypia by USCB and 4 (80%) were malignant in 5 benign papillary lesions with atypia by USCB. Among 18 lesions detected on MRI, 16 lesions showed suspicious findings on MRI, 11 lesions (69%) were diagnosed as benign and 5 (31%) were malignant. Among 12 lesions detected on diffusion weighted imaging, 10 lesions were diagnosed as benign and 2 were malignant. MRI findings were not significantly correlated with pathologic results at excisional biopsy. Conclusion : MRI findings were not useful to predict malignancy in benign papillary lesions diagnosed at USCB, because MRI findings of these were mostly suspicious (88.9%, 16/18). The benign papillary lesion should be included in the false positive lesion on breast MRI.

Background and Objectives: This study aimed to analyze the features of patients with papillary thyroid carcinoma (PTC) recurred as distant metastases (DM). Materials and Method: We retrospectively reviewed and analyzed clinical records of 63 patients who were treated for PTC recurred as DM between 2000 and 2006. Univariate and multivariate analyses of various clinical factors were performed. Results: Male patients were 12, and female patients were 51. The 5- and 10-year survival rates for PTC recurred as DM were 85% and 73%, respectively. Size of tumor, multiplicity of tumor, lateral neck node metastasis, and RAI ablation therapy with other treatments such as surgery were associated with survival rate (p < 0.005) in univariate analysis. The lateral neck node metastasis[p =0.039, hazard ratio=2.2(95% CI. 1.18~3.24)] and multiple organ DM[p =0.041, hazard ratio=2.18(95% CI. 1.03~2.89)] were related to the survival in multivariate analysis. Conclusion: PTC recurred as DM is uncommon (2.2%). The size of tumor, the multiplicity of tumor, lateral neck node metastasis and RAI ablation therapy with other treatments for DM were revealed as associated factors for the survival. Evaluation of DM should be considered in patients with PTC during long-term follow-up.

Background and Objectives : Although it is well established that patients with papillary thyroid microcarcinoma (PTMC) have a highly favorable prognosis, the extent of thyroid surgery for PTMC remains unclear. According to the 2011 revised Korean Thyroid Association guideline, the choice of surgical strategy(total thyroidectomy versus lobectomy) for PTMC depends on solely preoperative diagnostic scrutinies-ultrasonography and fine needle aspiration cytology. We want to know how accurately these preoperative diagnostic scrutinies define the choice of surgical strategy for PTMC. Materials and Methods : For 119 patients who underwent total thyroidectomy with central neck dissection for PTMC, retrospectively, we compared the choice of surgery according to preoperative work up and postoperative pathologic findings. Results : Overall accuracy of the choice of surgery by preoperative work up was 61%. Among patients recommended lobectomy on preoperative work up, completion thyroidectomy on postoperative pathology might be necessary for 60% of patients and hidden central node metastasis was revealed in 31% of patients. Conclusions : The results of this study compel us to reinvestigate the current treatment guideline for PTMC. On current guideline according to the sonography and fine needle aspiration cytology, it might be thought to be better to choose more aggressive surgical strategy.
