Hemangiomas that arise in cervical esophagus are extremely rare, representing 3.3% of all benign esophageal tumors. Although endoscopic mucosal resection (EMR) and potassium titanyl phosphate/yttrium aluminum garnet (KTP/YAG) laser therapy have been used with success for small tumors, the safety and efficacy in the case of large tumors remains uncertain. We report the successful resection of cervical esophageal hemangioma through a cervical esophagotomy in a patient with thyroid cancer who needed a cervical collar incision.

Solitary fibrous tumors (SFTs) are rare neoplasms arising from mesenchymal cells. Although most SFTs are benign, rare cases of metastasis have been reported at various sites. Complete surgical resection is the mainstay of treatment for both primary and recurrent or metastatic SFTs. Herein, we present a case of an SFT initially identified in the anterior mediastinum that later developed multiple metastases, even to the thyroid gland. The patient underwent repeated surgical resection and is currently being followed up in an outpatient setting.

Thyroid carcinoma is relatively rare in children. Eight cases of thyroid carcinoma were among 18 patients operated upon for thyroid tumors at Pediatric Surgery, Asan Medical Center in 11 years' period between 1989 and 2000. Five patients were boys and three were girls. The age distribution ranged from 10 to 14 years with a median age of 11.6 years. We studied clinical presentations, diagnostic workup, pathology, treatment, and follow-up (recurrence, mortality, and survival). All patients presented with anterior neck mass but one with multiple cervical lymph nodes enlargement. Familial history of thyroid cancer was seen in one case. All patients had a cold nodule by 1-131 thyroid scan. Fine needle aspiration (FNA) biopsy was performed in all patients. The right lobe was involved in four patients and the left lobe in two. Two had both lobes involvement. Pathologically, six cases were papillary carcinoma, one was follicular carcinoma, and one insular carcinoma. Four patients underwent unilateral lobectomy and isthmectomy. Total thyroidectomy was performed in three patients. The insular carcinoma case was preoperatively diagnosed as follicular neoplasm by FNA. After confirmation of the pathology by initial right thyroid lobectomy, total thyroidectomy was subsequently done. Cervical lymph node metastases were presented in three cases (37.5%), and lung metastasis in two cases (25%). Three patients received postoperative I-131 ablation. After a median follow-up of 53 months, all patients were alive without evidence of recurrence. In conclusion, thyroid carcinoma in children is frequently associated with lymph nodes involvement and distant metastasis, however, the prognosis is relatively good.

The papillary carcinoma is the most common malignant neoplasm of thyroid gland and the prognosis is better than anyother type of thyroid carcinoma. However, the thyroid is closed to the important organs such as esophagus, trachea and larynx, there are some possibilities to invade these organs. In case of advanced disease, not only surrounding structures but also mediastinum and cervical lymphatic chain can be involved or distant metastasis develops frequently. Therefore in these cases the prognosis is worse and the rate of inoperable case is more than those of non-metastatic group. Generally, the treatment modality for papillary thyroid carcinoma consists of surgery, postoperative thyroid hormone and radioiodine therapy. If the tumor invades surrounding structures, cervical lymph node or mediastinum, total thyroidectomy and wide excision of tumor invaded area including mediastinal dissection and neck dissection is necessary. Recently, the authors have experienced a case of locally invasive and recurred papillary thyroid carcinoma without treatment for 7 years. The patient was performed previously thyroid lobectomy and isthmusectomy 13 years ago. We had determinded surgical therapy for this patient and performed mass excision with overlying skin, completion total thyroidectomy, right type I modified radical neck dissection, left lateral neck dissection, thoracotomy with supramediastinal dissection, shaving of diffusely involved trachea and skin defect reconstruction with pectoralis major myocutaneous flap. After operation 2 cycles of radioiodine therapy were taken. Now the patient is following up at the outpatient base and no evidence of disease state for postoperative 16 months. So we report on this case with a brief review of literature.

Purpose: The purpose of this study was to investigate the effects of the information providing program of $I^{131}$ treatment on the pre-treatment anxiety and immune response of patients with thyroid cancer. Method: The used design was a nonequivalent control group design with pretest and post-test. Subjects of this study were 54 patients who had received a total thyroidectomy. They were given a information providing program with a brochure before 4 weeks of the hospitalization for $I^{131}treatment$, with problem solving phone counseling before 2 weeks of the hospitalization. Collected data were analyzed using the SPSS WIN program. Result: Hypothesis one, "The anxiety score of an experimental group would be lower than the score of a control group" was supported(t = -2.12, p = .03). Hypothesis two, "The level of cortisol of an experimental group would be lower than the level of a control group" was supported(t = -3.19, p = .00). However, hypothesis three "The level of T, B and N-K cells of an experimental group would be higher than the level of a control group" was not supported. Conclusion: The information providing program of $I^{131}$ treatment effectively decreased the anxiety of patients with thyroid cancer.

Ovarian cancer is common malignant disease with high mortality in the female. However, lymph node metastasis in the head and neck of ovarian cancer is very rare than in para-aortic, pelvic lymph node. A 49-year-old female patient came to our clinic with a left neck mass. After total thyroidectomy and left selective neck dissection for the cervical neck level II, III, IV, V, VI for ovarian cancer and thyroid cancer, she had already undergone chemotherapy (Paclitaxel+Carboplatin) 18 month ago. CT scan showed only lymph node enlargement in left neck level II. Positron emission tomography-computed tomography (PET-CT) revealed a hypermetabolic lesion in same area but no other hypermetabolic lesion, especially in the pelvic and abdominal cavity. Fine needle aspiration cytology revealed metastatic carcinoma. The serum level of CA-125 was elevated to 43.8U/mL, whereas other tumor markers (CA 19-9, CEA) were in the normal range. She underwent a revision of selective neck lymph node dissection for the cervical neck levels I, II, and III, and on the review of surgical pathology, metastatic carcinoma was suspected. Thus, we performed immunohistochemical staining for the tissue; as a result, it was finally diagnosed as metastatic ovarian cancer (positive for CK7, ER and PR, and negative for CK20). Adjuvant chemotherapy (Paclitaxel+Carboplatin) was planned on the tumor board, and the patient successfully received chemotherapy.

Objective: To compare core needle biopsy (CNB) and repeat fine-needle aspiration (rFNA) to reduce the rate of diagnostic surgery and prevent unnecessary surgery in nodules initially diagnosed as atypia/follicular lesions of undetermined significance (AUS/FLUS). Materials and Methods: This study included 231 consecutive patients (150 female and 81 male; mean age ± standard deviation, 51.9 ± 11.7 years) with 235 thyroid nodules (≥ 1 cm) initially diagnosed as AUS/FLUS, who later underwent both rFNA and CNB. The nodules that required diagnostic surgery after the biopsy were defined using three different scenarios according to the rFNA and CNB results: criterion 1, surgery for low-risk indeterminate (categories I and III); criterion 2, surgery for high-risk indeterminate (categories IV and V); and criterion 3, surgery for all indeterminate nodules (categories I, III, IV, and V). We compared the expected rates of diagnostic surgery between CNB and rFNA in all 235 nodules using the three surgical criteria. In addition, the expected rates of unnecessary surgery (i.e., surgery for benign pathology) were compared in a subgroup of 182 nodules with available final diagnoses. Results: CNB showed significantly lower rates of nondiagnostic, AUS/FLUS, and suspicious for malignancy diagnoses (p ≤ 0.016) and higher rates of follicular neoplasm or suspicious for a follicular neoplasm (p < 0.001) and malignant diagnoses (p = 0.031). CNB showed a significantly lower expected rate of diagnostic surgery than rFNA for criterion 1 (29.8% vs. 48.1%, p < 0.001) and criterion 3 (46.4% vs. 55.3%, p = 0.029), and a significantly higher rate for criterion 2 (16.6% vs. 7.2%, p = 0.001). CNB showed a significantly lower expected rate of unnecessary surgery than rFNA for criterion 1 (18.7% vs. 29.7%, p = 0.024). Conclusion: CNB was superior to rFNA in reducing the rates of potential diagnostic surgery and unnecessary surgery for nodules initially diagnosed as AUS/FLUS in a scenario where nodules with low-risk indeterminate results (categories I and III) would undergo surgery.

Purpose: Definite diagnosis of follicular thyroid carcinoma (FTC) is based on the presence of capsular or vascular invasion. To date, no reliable and practical method has been introduced to discriminate this malignant neoplasm from follicular thyroid adenoma (FTA) in fine needle aspiration biopsy material. Matrix metalloproteinase-2 (MMP-2), by degrading extracellular matrix, and caspase-3, by induction of apoptosis, have been shown to play important roles in carcinogenesis and aggressive behavior in many tumor types. The aim of this study was to examine expression of MMP-2 and caspase-3 in thyroid follicular neoplasms and to determine their usefulness for differential diagnosis. Method: Sixty FTAs and 41 FTCs were analysed immunohistochemically for MMP-2 and caspase-3. Result: MMP-2 was positive in 4 FTCs (9.8%), but in none of FTAs, with statistical significance (p= 0.025). Caspase-3 was positive in 30 (50%) of FTAs and in 27 (65.9%) of FTCs. Conclusion: Our results show MMP-2 expression only in FTCs and suggest that this protein may be a useful marker to confirm diagnosis of FTC versus FTA with 100% specificity and 100% predictive value of a positive test. We failed to show any differential diagnostic value for caspase-3 in thyroid follicular neoplasms.

Background and Objectives: Anaplastic thyroid carcinoma (ATC) is commonly related with concurrent differentiated thyroid carcinoma (DTC). We aimed to examine the clinicopathologic characteristics, prognosis and gene expression of DTC with anaplastic foci. Materials and Methods: Eighteen patients with DTC with anaplastic foci were enrolled in this study. To compare the clinicopathologic characteristics and prognosis of anaplastic foci subjects with conventional ATC or DTC, we additionally included 12 ATC and 1030 DTC patients who diagnosed during same period. Immunohistochemistry was performed to check the gene expression in anaplastic foci and DTC component. Results: In anaplastic foci group, tumor size was larger ($2.5{\pm}1.3$ vs. $1.2{\pm}0.9cm$, p=0.001), distant metastasis was more frequent (11.1 vs. 0%, p=0.000) and 1-year survival rate was low (88.9 vs. 100%, p=0.000) than DTC group. In contrast, compared with ATC group, anaplastic foci group showed younger age at diagnosis ($50{\pm}16$ vs. $63{\pm}18years$, p=0.039), smaller tumor size ($2.5{\pm}1.3$ vs. $3.8{\pm}1.4cm$, p=0.027), less distant metastasis (11.1 vs. 41.7%, p=0.084) and longer 1-year survival rate (88.9 vs. 25.0%, p=0.001). Expression of p53 protein was observed in 100% of anaplastic foci, ATC and 12.5% of papillary thyroid carcinoma component. Conclusion: DTC with foci of anaplastic transformation has a worse prognosis than DTC, but a better prognosis than ATC. Our results support that DTC with anaplastic foci was intermediate state from DTC to ATC.

Thyroid cancer, characterized by high incidence rates, good prognosis, and frequent recurrence, is typically treated surgically. However, since the early 2000s, radiofrequency ablation, which is commonly utilized in liver, lung, and kidney cancers, is being performed for management of primary and recurrent thyroid cancers. Many studies have focused on inoperable cases of low-risk papillary microcarcinoma (≤ 1 cm) and some have investigated its role in larger lesions (up to 4 cm). Overall, these studies have reported positive results. Radiofrequency ablation for recurrent cancer has primarily been performed for locally recurrent cervical cancer, and this therapeutic approach has been attempted for treatment of distant metastases in lungs and bones, with encouraging outcomes. A growing global trend, particularly in South Korea, the United States, and Europe supports radiofrequency ablation for thyroid cancer. However, this therapy is currently not recognized as a treatment option recommended by universally accepted clinical guidelines such as those established by the National Comprehensive Cancer Network. Based on past efforts and future research, radiofrequency ablation is expected to play a key role in thyroid cancer treatment in the near future.
