, Yoon Jin Choi, Ji Yeon Byun, You Won Choi, Joo Young Roh, Hae Young Choi Nontuberculous mycobacterial infections, which are often acquired from environmental sources such as water and soil, exhibit a variety of cutaneous manifestations that frequently lead to misdiagnoses and delays in treatment. A 77-year-old woman presented with multiple skin lesions in a sporotricoid distribution on her right leg, which persisted despite standard antibiotic treatments. Based on the skin biopsy, revealing granulomatous inflammation with acid-fast bacilli, and PCR testing, a nontuberculous mycobacterial infection was diagnosed. Antimycobacterial drug combinations, including clarithromycin, isoniazid, and rifampicin for 4 months, complete the skin lesion's clearance. This case underscores the need for heightened suspicion and the use of appropriate diagnostic techniques, including tissue biopsies and molecular methods such as PCR.

, Hee Jin Kim, Yeon Ah Sung, Nan Ho Kyung Thyroid nodule is a common clinical problem and it is important to distinguish benign from malignant nodule. Although features found on history taking, physical examnation and imaging studies help the diagnosis, fine needle aspiration(FNA) has been accepted as an accurate and reliable diagnostic procedure of thyroid nodule. This study was aimed to assess the values of FNA and needle biopsy in the diagnosis of thyroid nodules.
We reviewed the medical records of the 405 patients who underwent FNA and needle biopsy for the diagnosis of thyroid nodule form September 1993 to July 1996.
The 414 fine needle aspiration cytologic specimens were obtained from 405 patients(male : 26, female : 379). 390 cases(94.2%) were adequate for cytologic diagnosis. And the diagnosis showed benign in 357(91.5%), malignancy in 20(5.1%) and suspicious malignancy in 13(3.3%). Among the 357 benign cases, 104 cases were benign cysts, 163 cases were adenomatous goiter and 45 cases were follicular adenoma. 46 patients underwent thyroidectomy after FNA and 21 patients(45.7%) were diagnosed as having carcinoma. The sensitivity and specificity of FNA in diagnosing malignancy were 65% and 82%, respectively, with an accuracy of 74%. Of 46 patients, needle biopsy was done in 41. The sensitivity and specificity of the needle biopsy were 79% and 73%, respectively. And the accuracy was 76%. Hoarseness was developed in one patient after FNA and needle biopsy, and small amount of hemoptysis was developed in another patient after FNA.
Although it had been expected that needle biopsy may increase the diagnostic accuracy, our study didn't show the superiority of needle biopsy as compared with FNA. FNA has limitations in suspicious and nondiagnostic results but it is a safe, simple, reliable and cost-effective means of evaluating thyroid nodules. It is the preferred initial diagnostic method in all patients with thyroid nodule.

Although perforation rate during diagnostic evaluation has been reported as low about 0.03%, gastrointestinal perforation is a critical problem to the patients owing to significant morbidity and hospital stay. Therefore, all endoscopists should know the risk factors for the perforation and pay attention to avoid this complication. We experienced a case of 66 year-old-male with duodenal microperforation after endoscopic biopsy. During endoscopic examination, a submucosal mass was detected at duodenal second portion and endoscopic biopsy was performed. After this, he complained of severe abdominal pain during colonoscopy. Emergent simple abdomen and abdominal computed tomography revealed multiple free air in retroperitoneal space and duodenal perforation was suspicious. He was treated with primary closure and then recovered completely. Therefore, we report a case with microperforation after endoscopic duodenal biopsy.
