세기관지를 침범하는 많은 질환들이 세기관지에 유사한 병리소견을 일으킴으로 이들의 원인, 병인, 진단을 위하여서는 임상 및 병리소견을 연관시킴이 거의 필수적이다. Small airways disease를 포함한 세기관지 질환의 병리소견 특히 호흡성 세기관지염, bronchiolitis obliterans organizing pneumonia, constrictive bronchiolitis obliterans 등에 대하여 중점적으로 기술하였다. BOOP은 어떤 급성 폐손상에 대한 비특이성 소견이며 조직병리적인 기술이다. 반면 Idiopathic BOOP은 COP와 동의어로써 특정한 질환이며 이의 주된 병리소견이 BOOP인 것으로 이해하는 것이 좋겠다. Constrictive bronchiolitis obliterans는 임상적으로나 병리학적으로 BOOP과는 다르다고 하겠다.

The endoscopic pathological findings of gastrointestinal tract (GIT) are important in the early diagnosis of colorectal cancer. Deep learning based on convolutional nueral network (CNN) has been implemented to solve the subjective analysis problem and to increase the performance of early detection of pathological findings. However, the desired performance is yet to be achieved and CNNs are computationally complex. To solve these problems, in this paper, we propose a vision transformer based endoscopic pathological findings classification for the early detection of colorectal cancer. Publicly available endoscopic images with three pathological findings, including esophagitis, polyps, and ulcerative colitis, each with 1000 images were used. Using our approach, we have achieved a test accuracy of 98% in classifying the three pathological findings.

In this case report, we present the radiologic and pathologic findings of atypical ductal hyperplasia (ADH) in the male breast. It is well known that a high-risk lesion such as ADH is a precursor of breast cancer in females. However, the clinical significance of these lesions in the male breast is still uncertain because male breasts mainly consist of ducts without lobule formation, unlike the female breast. To our knowledge, imaging findings of ADH in the male breast have not been reported previously, except for a few studies on the pathologic findings of these lesions. Through this paper, we would like to present the possible imaging features of this high-risk lesion in the male breast and review the related literature.

콜레스테롤 육아종은 콜레스테롤 결정이 주위조직에 이물질로 작용하여 육아성 반응 및 골파괴 반응을 유발시키는 질환으로 병리조직학적으로 많은 콜레스테롤 결정이 거대세포를 가진 만성적인 염증성 침윤속에 나타나는것을 특징으로 한다. 이 병변은 아주 드물지만 특징적인 방사선적소견, 병리조직학적 소견과 임상양상으로 쉽게 진단이 된다. 두부에서는 다양한 위치에서 발견되는데 특히 함기화가 잘 된 측두골, 유양동, 고실강에서 많이 보이며 전두골, 상악골, 협골, 인상측두골 및 후두개와에서도 보고되고 있으나 부비동에 발생하는것은 특히 드물다. 부비동에서 발생한 콜레스테롤 육아종의 발생기전은 환기장애설, 배출장애설 및 출혈설 등으로 보고되고 있다. 저자들은 최근 복시와 측두통을 호소하는 50세 여자환자에서 접형동에 발생한 콜레스테롤 육아종이 우측 상안와열 (superior orbital fissure)과 경사대(clivus)를 파괴하며 전교조 (Prepontine cistern)로 확장된 1례를 경험하였기에 임상 증세, 특징적인 전산화단층 및 핵자기공명소견과 병리조직학적인 소견을 문헌 고찰과 함께 보고하는 바이다.

Angiosarcoma of the breast is a rare malignant sarcoma of endovascular origin that presents with various radiological findings. We encountered a case of angiosarcoma of the breast presenting as an irregular indistinct hyperechoic mass on ultrasonography, with a large single angiosarcoma of the spleen in a previously healthy 36-year-old female. Herein, we report the imaging and pathologic findings and review the literature.

Background : Tumor size in lung cancer is not as good a prognostic factor for adenocarcinoma as it is for other types of lung cancer; therefore it is difficult to estimate the prognosis preoperative. However, there have recently been some reports on the radiologic findings correlating to the clinicopathologic prognostic factors in peripheral small adenocarcinoma of lung. We tried to evaluate the prognostic importance of High-Resolution CT (HRCT) findings of such adenoearcinoma, Material and Method: One houndred and seventy-six surgically resected small peripheral adenocarcinoma measuring 3 cm or less in greatest dimension were reviewed radiologically and clinicopathologically. Result: The patients with greater extent of ground-glass attenuation (GGA) had better clinico-pathological factors. The tumors with gross appearance of GGA or bubble-like shape showed better clinicopathological prognostic factors than scar-like or solid shape. Conclusion: HRCT findings of small peripheral adenocarcinomas of the lung correlated well with the histologic and clinical prognostic factors. We can predict the post-operative prognosis with the radiologic findings.

Purpose: Recently, a wide application of gastrofiberscopy in the pediatric group have revealed that nodular duodenitis is not an uncommon disease in children and is suspected to be associated with H. pylori infection. The aim of this retrospective study was to investigate the clinical and histopathologic features in children with nodular duodenitis, and to assess the correlations beween both. Methods: During a period of 5 years (Jan. 1995~Dec. 1999), we investigated clinical, endoscopic and histopathologic features of 39 consecutive patients diagnosed as having nodular duodenitis at Pediatric department of Seoul Red Cross Hospital. In 35 children with nodular duodenitis endoscopic biopsy specimens were stained with Hematoxylin & Eosin and Giemsa's stain, and were graded according to the criteria outlined by Triadafilopoulos, Whitehead et al., and Prieto et al.. Statistical analyses were performed with Graph PAD InStat. Results: The prevalence rate of nodular duodenitis was 17.1% and the most frequent chief complaint was abdominal pain (69.2%). Endoscopically grade 1 was the most common (45.7%) and nodular gastritis was coexistent in 28.3%. The most common histology of the duodenum was grade 2 (54.3%), and the most common histologic score of the stomach was 2 (42.9%). H. pylori was found in the duodenum in 37.1%, and in the stomach in 31.4%. The correlation coefficient between the endoscopic grade and the histologic grade of nodular duodenitis was 0.3983 (p=0.0178). And the correlation coefficient between the histologic grade and the grade of H. pylori colonization in the duodenum was 0.5154 (p=0.0018). Conclusion: There was significant correlation between the endoscopic grade and the histologic grade of nodular duodenitis, and was also significant correlation between the histologic grade and the grade of H. pylori colonization in the duodenum. Therfore H. pylori infection should be regarded as an etiologic factor of nodular duodenitis.
