Purpose: To study the clinical application value of ultrasound guided thyroid fine needle aspiration biopsy and thinprep cytology testing in diagnosis of thyroid disease. Methods: A total of 78 patients with thyroid nodules were enrolled, 34 males and 44 females, aged 33-64 years old with mean age of 47.6 years. All underwent thyroid module fine needle puncture after surgery to assess cell pathology and histopathological features. Results: Sufficient specimens were obtained from all of 78 patients, the cytological results of 73 cases (93.6 %) being consistent with pathological results. While 20 cases (25.6 %) were malignant tumors, 44 (56.4 %) were benign and 9 (11.5 %) were non-tumor lesions. The sensitivity of benign and malignant thyroid nodule by thyroid fine needle puncture was 90.9 %, specificity was 98.1 % and the positive predictive value was 96.3 %. Conclusions: It is demonstrated that ultrasound-guided thyroid fine needle aspiration biopsy and thinprep cytology testing have diagnostic value in clinical application for thyroid disease,showing good diagnostic coincidence rates with histopathological examination. They can thus be regarded as safe and effective for preoperative diagnosis and providing an appropriate basis for selection of surgery.

Background and Objectives： Necrotizing lymphadenitis or Kikuchi's disease is characterized by cervical lymphadenopathy of unknown etiology with unique histologic findings in young female patients. The importance of this disease lies in the fact that it can be easily misdiagnosed as malignant lymphoma, hence, clinicians need to aware of this disease entity. The purpose of this study is to report the clinicopathologic findings, radiographic findings, and many laboratory tests in order to contribute to the diagnosis and treatment of necrotizing lymphadenitis. Materials and Methods： We evaluated 31 patients, who were diagnosed as necrotizing lymphadenitis by excisional biopsy or fine needle aspiration cytology or ultrasound guided 18G cutting needle biopsy, retrospectively. Result : The median age was 24.8 years (range 12 to 43 years) and the male to female ratio was 1 : 2.4(9：22), with 14 females (45.1%) under 30 years. The common chief complaints were neck mass, easy fatigue and fever. Lymph node enlargement was limited to the cervical area in most cases (28cases : 90.3%). The involved lymph nodes were usually multiple (20cases : 64.5%), unilateral (26cases 83.9%) and small sized. Leukopenia (19cases : 61.3%) and elevation of ESR (18cases : 58.1%) appeared most frequently in the abnormal laboratory data. These symptoms will be gone spontaneoulsy without any specific treatment in several weeks or months. Conclusion : We should consider open biopsy or fine needle aspiration cytology or ultrasound guided cutting needle biopsy with lymph node in patients who have cervical lymphadenopathy with easy fatigue and fever, especially young women to exclude other conditions such as malignant lymphoma and tuberculosis, etc.

Objectives: Fine needle aspiration cytology(FNAC) is a well established preoperative diagnostic procedure in the thyroid nodules. However, diagnostic accuracy of FNAC varies according to the size and the structural characteristics of thyroid nodule. We performed the ultrasound guided FNAC(US-guided FNAC) for impalpable thyroid nodule, and estimated the sampling accuracy rate through a comparison study between the cytologic diagnosis and the final histologic diagnosis of the postoperative specimens in order to determine clinical efficacy of the US-guided FNAC. Materials and Methods: We evaluated 117 patients underwent US-guided FNAC from January 1997 to December 1998. These patients had 129 thyroid nodules to need cytologic examination. Whereas the nodules were so no graphically classified into cystic, solid, and mixed type according to echo pattern, the aspirated thyroid specimens were classified into benign, malignant, suspicious, and insufficient. Results: Positive sampling for diagnositc examination was achieved in 75 nodules(58.1%), and US-guided FNAC in our study showed the accuracy rate of 95.2%, false positivity rate of 0%, and false negativity rate of 5.5%. Conclusions: US-guided FNAC is a powerful techniques for evaluating cytologic characterics and allowing a reliable diagnositc result in the impalpable thyroid nodule. However, the experienced technique is recommanded in order to obtain the sufficient samples for reliable results.

We report here a case of a gastrointestinal stromal tumor (GIST) in the stomach that was diagnosed by endoscopic ultrasound-guided fine needle aspiration cytology (EUS-FNA). A 67 year old male patient underwent regular check-ups for five years due to the presence of a submucosal tumor that was found in the fundus of the stomach incidentally. EUS-FNA was performed to evaluate the tumor, which had increased in size from 1 cm to 2.8cm. A cytologic smear revealed cohesive sheets or clusters of spindle cells with elongated nuclei. Immunohistochemical staining revealed a strong positive reaction for c-kit and CD34, without any reaction for smooth muscle actin and Ki-67. Therefore, a diagnosis of GIST was made.

Pancreatic cancer, the 4th leading cause of cancer-related death in the United States, has a very poor prognosis. Cholangiocarcinoma originates from either intrahepatic or extrahepatic bile duct, and its incidence is gradually increasing worldwide. Endoscopic retrograde cholangiopancreatography with brush cytology has a high false-negative rate for the diagnosis of biliary malignancy. Recently, endoscopic ultrasonography (EUS) has emerged as the potential modality to detect pancreatic cancer. EUS-guided fine needle aspiration for cytologic analysis made it possible to overcome the obstacle in differentiating between benign and malignant lesions in the pancreatobiliary lesion, and it has been well established as a safe and effective procedure. Herein, the clinical application of EUS in the diagnosis of pancreatobiliary cancer was reviewed.

Objective: To evaluate the feasibility and diagnostic performance of ultrasound (US)-guided fine-needle aspiration cytology and core-needle biopsy (US-FNAC/CNB) for the diagnosis of laryngo-hypopharyngeal masses. Materials and Methods: This was a single-center prospective case series. From January 2018 to June 2019, we initially enrolled 40 patients with highly suspicious laryngo-hypopharyngeal masses on laryngoscopic examinations. Of these, 28 patients with the mass involving or abutting the pre-epiglottic, paraglottic, pyriform sinus, and/or subglottic regions were finally included. These patients underwent US examinations with/without subsequent US-FNAC/CNB under local anesthesia for evaluation of the laryngo-hypopharyngeal mass. Results: Of the 28 patients who underwent US examinations, a laryngo-hypopharyngeal mass was identified in 26 patients (92.9%). US-FNAC/CNB was performed successfully in 25 of these patients (96.2%), while the procedure failed to target the mass in 1 patient (3.8%). The performance of US caused minor subclinical hematoma in 2 patients (7.7%), but no major complications occurred. US-FNAC/CNB yielded conclusive results in 24 (96.0%) out of the 25 patients with a successful procedure, including 23 patients with squamous cell carcinoma (SCC) and 1 patient with a benign mass. In one patient with atypical cells in US-FNAC, additional direct laryngoscopic biopsy (DLB) was required to confirm SCC. Among the 26 patients who received US-FNAC/CNB, the time from first visit to pathological diagnosis was 7.8 days. For 24 patients finally diagnosed with SCC, the time from first visit to the initiation of treatment was 25.2 days. The mean costs associated with US-FNAC/CNB was $272 under the Korean National Health Insurance Service System. Conclusion: US-FNAC/CNB for a laryngo-hypopharyngeal mass is technically feasible in selected patients, providing good diagnostic performance. This technique could be used as a first-line diagnostic modality by adopting appropriate indications to avoid general anesthesia and DLB-related complications.

갑상선 질환은 임상에서 흔히 볼 수 있는 내분비계 질환이다. 기존의 FNA (미세침흡인검사)는 갑상선결절 진단에 매우 널리 이용되고 있으나 결절의 크기가 작고 불분명한 경우, 심부에 위치하여 촉진이 어렵거나, 복합 낭종인 경우에는 적절한 표본 획득의 어려움 등의 제한점을 가지고 있다. 이러한 제한점을 최소화하고 검사의 정확성을 높이기 위한 방법의 하나로써 최근에는 US-guided FNA (초음파유도 미세침흡인검사)가 활발히 시행되고 있다. 이에 이 연구에서는 한 대학병원에서 시행되고 있는 US-guided FNA의 결과를 분석하여 표본의 정확성을 파악함으로써 US-guided FNA의 진단적 유용성을 알아보고자 하였다. 갑상선 결절로 US-guided FNA를 시행 받은 364명의 연구대상자중 성별은 여성이 316명(86.8%)으로 월등히 많았으며 연령층은 40대의 비율(51.4%)이 가장 높은 것으로 나타났다. 결절의 위치는 오른쪽이 157명(43.1%), 왼쪽이 130명(35.7%), 협부 9명(2.5%)의 순이었다. 결절의 크기는 1cm 미만인 경우는 38.2%, 1cm 이상인 경우는 61.8%인 것으로 확인되었으며, 결절의 내부 에코 양상은 고형성인 경우가 255명(70.1%)으로 가장 많았으며 낭성은 39명(10.7%), 혼합형인 경우는 19.2%이었다. 병리검사 결과 양성 307명(84.3%), 악성은 20명(5.5%), 악성의심이 4명(1.1%)이었으며, 부적절한 검체는 33명(9.1%)이었다. US-guided FNA는 표본의 적절성과 진단적 정확성을 향상시킬 것으로 기대되며 향후 진단적 정확성과 관련하여 감수성과 특이성, 예측도 등의 지표에 대한 연구들이 보완되어야 할 것으로 사료된다.
