혈장 cathepsin B 활성도 측정이 갑상선암 및 결절성 증식증의 수술 전 진단에 도움이 되는지를 알아보고자 분화갑상선암 32례, 결절성 증식증 7례, 대조군 5례의 혈장 cathepsin B 발현양상을 대조군과 함께 관찰하였다. 수술시 제거된 여포선암의 암조직, 결절성 증식증 조직의 cathepsin B 발현을 정상 조직과 비교하였다. 혈장 Cathepsin B 활성도는 정상 대조군에서 $168.94{\pm}15.10$ (${\times}10^{-2}$, mU), 결절성 증식증에서 $255.45{\pm}95.68$ (${\times}10^{-2}$, mU), 악성종양에서 $284.87{\pm}79.32$ (${\times}10^{-2}$, mU)로써 악성종양군과 결절성 증식증군에서 cathepsin B 발현이 정상 대조군보다 비교적 높게 나타났다(p<0.05). 혈장 cathepsin B의 정량적 비교를 위한 immunoassay결과에서도 결절성 증식증군($17.64{\pm}7.49\;ng/ml$)과 악성종양군($15.50{\pm}7.86\;ng/ml$)에서 정상대조군($4.85{\pm}0.61\;ng/ml$)보다 높은 수치를 나타내었다(p<0.05). 결절성 증식증 및 악성종양군의 조직 내 cathepsin B mRNA발현이 정상 조직에서보다 높게 나타났다. 따라서 혈장 cathepsin B는 갑상선세포의 비정상적인 증식시에 증가됨을 알 수 있으며, 갑상선암 혹은 결절성 증식증을 스크리닝하는데 이용될 수 있을 것으로 사료된다.

Pulmonary nodular lymphoid hyperplasia is a reactive lymphoproliferative disease. It is very rare, which means that many aspects of the disease are unknown or have not been proven. Pulmonary nodular lymphoid hyperplasia can be symptomatic or asymptomatic, progressive or not, and solitary or multiple, and a surgical approach is the current treatment of choice. We present a case of pulmonary nodular lymphoid hyperplasia that was visualized as multiple ground glass opacities on a computed tomography (C T) scan, and observed for 1 year because the patient was pregnant. Over this period, the number and extent of the opacities progressed, but no symptoms were reported. A surgical biopsy was done and some remaining lesions regressed on follow-up CT scans, while others progressed, without any appearance of symptoms.

Diffuse pulmonary ossification is rare disease of unknown etiology. Since the first description by Luschka in 1856, about 140 cases have been reported worldwide, but no such case has been reported in Korea yet. We report 40-year-old woman who was diagnosed as diffuse nodular pulmonary ossification on open lung biopsy. She has no respiratory symptoms & physical findings and no previous disease history. She was incidentally found to have multiple pulmonary nodules on roentgenographic examination. Open lung biopsy was done for above lesion and She was proven to have diffuse nodular pulmonary ossification. She was followed by roentgenographic examination and showed no progression.

Alimentary lymphoma accounts for approximately 5% of neoplasm and diffuse lesion is more common than solitary nodular form in dogs. An eleven year-old male Yorkshire terrier was examined because of nonspecific gastrointestinal symptoms such as anorexia and vomiting for 10 days. An abdominal mass was palpated, which was originated from small intestinal wall in abdominal ultrasonography. Small intestine was obstructed by hypoechoic mass and lost normal layering and measured 24.5m. After fine-needle aspiration, septic peritonitis due to intestinal rupture occurred and emergency surgery was performed. Solitary mass was found in small intestine and diagnosed as alimentary lymphoma through histopathologic examination. Conclusively, abdominal ultrasonouaphy could verify the thickened bowel, loss of wall layering and decrease of motility and percutaneous ultrasound-guided fine-needle aspiration is considered as useful diagnostic technique, especially in nodular form of alimentary lymphoma.

폐에서 발생한 경결 림프구성 증식증(Nodular Lymphoid Hyperplasia)은 빈도가 매우 낮은 질병으로 병리학적인 분류 역시 많은 변화가 있었다. 현재 경결 림프구성 증식증은 림프종과는 구별되는 B cell associated Lymphoid tissue에서 기원하는 림프구성 증식증으로 분류된다. 환자는 60세 남자환자로 특이 증상 없이 지내던 중 건강검진상 시행한 흉부전산화 단층 촬영에서 간유리상음영이 우폐 하엽에서 발견되어 우하엽 절제술 시행받은 뒤 병리학적 소견상 경결 림프구성 증식증이 진단되어 보고하는 바이다.

저자들은 배양에 성공한 결절성 갑상선종 2예와 유두성 갑상선암 2예에서 염색체 이상을 찾아내어 이러한 이상들이 서로 연관을 갖는지 여부를 연구하고자 본 실험을 시행하였다. 결절성 갑상선종의 염색체 형태는 매우 다양하게 나타나면서도 2예 모두가 특이적인 염색체 이상은 보이지 않았다. 제 1 예 : modal 염색체 슷자는 42에서 46범위 내였고 염색체 8, 19, 21, 22는 빈번한 결손을 보였다. 51개 분석 세포들 중에 9가지 구조적 변성이 관찰되었으나 집단 염색체 변화는 없었다. 제 2 예 : modal 염색체 수는 43이었고, 염색체 17과 19는 흔한 결손을 나타내었다. 이 두 결절성 갑상선종의 세포유전학적 특성은 저이배체(hypodiploidy)와 매우 다양한 염색체 양상을 나타내었다. 유두성 갑상선암에 대한 분석 결과는 다음과 같다. 제 3 예 : 다소의 숫적, 구조적 염색체 변화가 관찰되었으나 특이적인 염색체 이상은 찾아볼 수 없었다. 제 4 예 : 염색체 양상이 del(11)(q23)의 집단 염색체 변화를 수반하는 매우 다양한 이질적인 양상을 나타내었다. 유두성 갑상선암의 del(11)(q23) 염색체 변화는 이미 Eva Olah등이 1989년 보고한 바 있다. 아마도 갑상선에서 유두성 갑상선암의 암화과정에 11q 결손이 중요한 역할을 할 것으로 추정된다. 이상의 결과에 따르면 유두성 갑상선암과 결절성 갑상선종 둘 다 염색체 이상을 나타냈지만 양자간의 염색체의 특이적인 상관 관계를 발견할 수 없었다.

A 25 years old male patient with Hodgkin's disease, considered as complete remission, underwent $^{18}F$-FDG whole body PET/CT. $^{18}F$-FDG whule body PET/CT showed unexpected hypermetabolic nodule in left quadratus femoris muscle suggesting local recurrence. Subsequent MRI also revealed well-enhancing nodular lesion with intermediate and high signal intensity on T1WI and T2WI, respectively. The lesion was confirmed as nodular fasciitis by pathologic examination of the excited specimen.

The diffuse nodular lung lesion has a diagnostic problem and should be made differential diagnosis. A chest X-ray of 62-year-old male patient with dyspnea showed small-sized scattered multinodular lesion on entire lung field. Bronchoalveolar lavage and transbronchial needle aspiration showed the non-specific findings, so open lung biopsy was done and revealed bronchioloalveolar cell carcinoma.

A 2-year-old intact female dachshund dog was presented with recurrent subcutaneous nodules and fistulations on the neck, back and hip. The patient was diagnosed as a sterile nodular panniculitis based on the cytology, histopathology, and cultures for bacteria and fungus. The fistulas were surgically removed and methylprednisolone was administrated 2 mg/kg twice daily per oral. The lesions were all disappeared, but the relapses were happened when the dosage of the drug was tapered off. The repeated treatments with methylprednisolone or azathioprine were performed, consequently, the patient was controlled with relatively low-dosage methylprednisolone (0.25 mg/kg, every third day).

Differentiating central vestibulopathy from more common vestibular disorders is crucial because it often necessitates different treatment strategies, and early detection can help to minimize potential complications. Isolated nodular infarct is one of the central brain lesions that can mimic peripheral vertigo. We present a case of isolated nodular infarct that had been misdiagnosed as vestibular neuritis on the contralateral side at the initial evaluation. The patient was successfully treated with anticoagulants and antihyperlipidemic agents. Clinicians should keep in mind that some causes of central vertigo mimic peripheral vestibulopathy at the early stage.
