Purpose: Learning the concepts of pathology can be facilitated by repeated learning situations with illustrative pathology images. Virtual microscopes are digital facsimiles of glass slides that can be viewed on a computer screen. This study was designed to evaluate the possibility of using virtual microscopes as a teaching modality in the pathology laboratory. Methods: The virtual microscope was produced from high resolution images scanned by an exclusive slide scanner from newly made teaching glass slides. The final teaching material was put up on personal computers in the computer laboratory, classroom, and medical library. Results: This material was easily accessed by exclusive viewers. The students readily adapted to the use of virtual microscopes. The quality of the images in this material was appropriate for viewing. The response from the students displayed highly significant differences between the traditional and virtual microscopes, with the virtual microscope being preferred. Conclusion: The virtual microscopes in this study were helpful for medical students studying pathology. The results of this implementation suggest that virtual microscope technology may be extended to other educational venues where traditional microscopes and photomicrographs are currently used.

IgA nephropathy can occur commonly in alcoholic liver cirrhosis and is the most common form of secondary IgA nephropathy. Defective clearance of IgA-containing complexes by liver is thought to contribute to the development of IgA nephropathy in alcoholic cirrhosis. Although IgA deposition is found up to 64% in autopsy cases of alcoholic cirrhosis, most patients have mild clinical symptoms, and nephrotic range proteinuria occurs rarely in these patients. We report a case of IgA nephropathy with a membranoproliferative pattern that is detected with unusual massive ascites in a patient with alcoholic liver disease. A 60-year-old male patient was referred to our hospital for evaluation and management of abdominal distension. Abdominal ultrasonographic findings were compatible with diffuse liver cirrhosis with splenomegaly and large amount of ascites. He had nephrotic range proteinuria, azotemia, hyperlipidemia, and hematuria in dipstick. Renal biopsy performed under the impression of acute nephritis revealed mesangial and endocapillary proliferative glomerulonephritis with double contour of capillary loop. Immunofluorescence findings showed mesangial IgA and C3 deposit, compatible with IgA nephropathy. He was treated with high dose steroid, and steroid was tapered during 2 months. Steroid treatment induced complete remission state, and ascites was resolved.

소아에서 관찰된 IgG-associated mesangial glomerulonephritis 2례

이상후,김병길,송지선,Lee, Sang-Hoo,Kim, Pyung-Kil,Song, Ji-Sun 대한소아신장학회 2008 Childhood kidney diseases Vol.12 No.1

IgG 신병증(IgG-associated mesangial glomerulonephritis)은 전세계적으로 드물게 보고되고 있는 새로운 원발성 사구체 질환으로 1993년 Sato 등에 의해 처음으로 보고되었고 이후 1994년 Yoshikawa 등에 의해 소아에서의 10례가 보고되었다. 주로 단백뇨를 주소로 하며 현미경적 혈뇨를 동반하기도 한다. 이 질환은 조직 면역 형광 검사상 사구체 간질에 IgG의 침착을 보이는 사구체 신염이다. 이 질환은 초기에는 양성 경과를 취하는 것으로 알려졌으나 2002년 Fakhouri 등은 대부분은 양성 경과를 보이지만 일부는 말기 신부전증으로 진행함을 관찰할 수 있었으며 1례에서는 신장이식 후 이식신에서 IgG 신병증이 재발된 예도 보고 하였다. 본 증례에서는 한명은 신증후군이 동반되었고 한명은 무증상 현미경적 혈뇨만을 보였다. 이들 모두 면역 형광 현미경 소견상 사구체 간질에 IgG 침착이 주로 보였고 IgM, 보체의 침착도 보였다. 또한 전자현미경 소견상 사구체간질에 고밀도 전자 침착이 보였다. 신생검에서 면역 현미경 소견과 전자 현미경 소견으로 진단된 IgG 신병증 소아환자 2례를 경험하고 국내에서는 아직 보고된 예가 없기에 문헌 고찰과 함께 증례를 보고하는 바이다. Rare cases of IgG associated mesangial glomerulonephritis(IgG GN) defined by exclusive or predominant mesangial IgG deposits were reported first by Sato et al.(1993). and subsequently 10 pediatric cases were reported by Yoshikawa et al.(1994). Previous reports suggested that the prognosis of IgG GN is relatively benign course but recent report suggested that prognosis of IgG GN is highly variable. Also the recurrence of IgG GN in a renal transplant was reported by Fakhouri et al. (2002). Such a recurrence highlights the specificity of this type of glomerulonephritis. We experienced two pediatric cases of IgG GN proven by renal biopsy. Case 1. 4-year-old girl with nephrotic syndrome admitted because of general edema. The patient's urinalysis showed proteinuria and microscopic hematuria. Renal biopsy was performed because of relapsed nephritic syndrome. Light microscopic finding was nonspecific with almost normal histology. Immunofluorescent findings showed diffuse segmental IgG(+) and IgM(+) deposits in the capillary walls, and focal segmental spotty C4(trace), C1q(trace) deposits. Electron microscopic findings showed focal portion of mesangial electron dense deposits without mesangial widening. Case 2. 11-year-old girl admitted for evaluation of microsopic hematuria detected through mass school urinary screening program. Renal biopsy was performed for exact diagnosis. Immunofluorescent findings showed focal segmental IgG(+), IgM(+/-) and C3(+/-) deposits. Electron microscopic findings showed focal portion of mesangial electron dense deposits without mesangial widening.

비박형 사구체 기저막 질환이 동반된 중복 자궁 일측성 폐쇄질 및 동측 신장 무형성 증후군 ( Herlyn - Werner- Wunderlich syndrome ) 1례

김명수,박용준,박영준,박노혁,송지선,김병길,Kim, Myoung-Soo,Park, Yong-Jun,Park, Young-Jun,Park, Noh-Hyuck,Song, Ji-Sun,Kim, Pyung-Kil 대한소아신장학회 2007 Childhood kidney diseases Vol.11 No.2

HWW(Herlyn-Werner-Wunderlich) 증후군은 중복자궁, 일측성 폐쇄질 및 동측 신장 무형성을 보이는 비뇨생식기계의 선천성 기형으로 매우 드문 질환 중 하나이다. 대부분 초경 이후 발생하는 월경통이나 복강내 종물등으로 발견되지만, 본 증례는 소아에서 반복되는 요로 감염과 현미경적 혈뇨로 인해 진단된 경우이다. 복부 초음파 검사에서 일측 신무형성이나 중복 자궁의 소경이 보일 때는 이러한 뮬러관 기형의 가능성을 염두에 두어야 보다 빠른 진단이 가능하고, 환자의 고통 또한 중여줄 수 있을 것이다. 특히 반복되는 요로 감염시에도 단순한 감염 치료보다 정밀검사를 항상 염두에 두어야 할 것이다. Herlyn-Werner-Wunderlich syndrome(HWWs) is a rare variant of Mullerian ductal anomalies characterized by the presence of a hemivaginal septum, a didelphic uterus, and ipsilateral renal agenesis. It usually presents after menarche with progressive pelvic pain, and palpable mass due to hemihematocolpos. If a cystic mass is detected behind the urinary bladder in children, in association with the absence of a kidney, the diagnosis of uterus didelphys with imperforate vagina and hydrocolpos should be considered. When renal agenesis is found in asymptomatic children, the small size and the tubular shape of the uterus makes it almost impossible to evaluate uterine anomalies, so follow-up should be performed until the end of puberty. Appropriate preoperative diagnosis and treatment will prevent unnecessary procedures and offer relief of symptoms. We report one case of didelphic uterus with blind hemivagina and ipsilateral renal agenesis with biopsy- proven thin glomerular basement membrane disease which is not related to the above syndrome.

소아 IgA 신병증의 장기 추적(평균 10.8년)에 따른 임상 경과 및 병리학적 변화

문창민,김병길,임범진,송지선,정현주,Moon, Chang-Min,Kim, Pyung-Kil,Lim, Beom-Jin,Song, Ji-Sun,Jeong, Hyeon-Joo 대한소아신장학회 2010 Childhood kidney diseases Vol.14 No.2

목 적 : 소아 IgA 신병증의 임상 양상 및 병리학적 분류(Haas 분류)와 임상 경과와의 상관 관계를 조사하여 이들이 예후를 반영할 수 있는지 알아보고자 하였다. 방 법 : 병리학적으로 IgA 신병증으로 진단받고 추적 중이던 환자들 중 추적 신생검을 시행한 20명의 환자를 대상으로 후향적으로 자료를 분석하였다. 결 과 : 최초 신생검시 평균 9.5세였고 남자 16명, 여자 4명이었으며, 최종 조직 검사까지 평균 10.8년이 경과하였다. 안지오텐신 전환효소 억제제 등으로 치료를 지속한 후 정상뇨 소견, 정상 혈압, 정상 크레아티닌 청소율(CCr)을 보이는 임상적 관해 상태의 환자는 10명(50%)이었으며, 비관해 상태의 환자 10명(50%)도 초기와 비교하여 호전된 경과를 보였고, CCr이 중등도 이상 저하되거나 말기 신질환 양상을 보이는 환자는 없었다. 최초 Haas 분류는 임상경과와 상관 관계가 없었다. 초기 고혈압은 5명(25%)에서 보였고 이는 임상 경과(P =0.010) 및 최종 Haas 분류(P =0.007)와 유의성이 있었다. 초기 CCr의 중등도 저하는 Haas 분류와 유의성이 있었으나(P =0.048), 임상 경과와는 상관관계가 없었다. 결 론 : 소아 IgA 신병증의 추적 기간 중 임상 경과는 양호하나 최초 Haas 분류로 임상 경과를 예측할 수는 없었으나 적극적인 조기 진단 및 치료로 말기 신질환으로의 진행을 지연시킬 수 있을 것으로 보인다. 초기 고혈압은 임상 경과 및 최종 Haas 분류와 유의한 상관관계를 보여 적합한 예후인자로 보인다. 최초 병리학적 소견은 임상 경과를 반영하지 못하나, 추적 Haas 분류가 예후를 반영할 수 있을지에 대해서는 보다 많은 추적 관찰 및 추적 신생검을 통한 연구가 있어야 할 것으로 보인다. Purpose : We know little about the natural course of IgA nephropathy (IgAN) in association with histologic changes especially in children. We investigated clinicopathologic features with long-term follow-up biopsy to clarify the outcomes and prognostic indicators for childhood IgAN. Methods : From our patients' medical records, we retrieved 20 patients with IgAN, to whom renal biopsies had been performed for the initial diagnosis and follow-up to find out any histologic changes. Initial and follow-up biopsies were classified by Haas classification. The changes of these parameters were compared with the evolution of clinical features. Results : Patients were treated with angiotensin-converting enzyme inhibitors in combination with angiotensin receptor blockers (in subclass II or above) and short-term cyclosporine A(in patients showing nephrotic syndrome). Histologic improvement in 7 cases and deterioration in 3 cases were observed. At the time of last biopsy, 10 cases (50%) showed clinical remission and the others showed improved clinical features. These clinical outcomes did not correlate with initial Haas classifications. Hypertension at onset observed in 5 cases (25%) revealed significant correlation with clinical outcome (P =0.01) and last Haas classification (P =0.007). None of the cases showed progression to CRF or ESRD. Conclusion : During a mean follow-up of $10.8{\pm}3.4$ years, childhood IgAN showed good clinicopathologic outcome. Hypertension at onset was only a strong predictor of clinicopathologic outcomes, but initial Haas classification cannot predict outcomes in children. Histologic change of IgAN in long term follow-up period cannot be completely predicted by clinical data and vice versa. Therefore, a renal biopsy should be considered as a part of follow-up plan.

이건혁(Gun Hyuk Lee),송지선(Ji-Sun Song),윤소연(So Yeon Yoon),조윤진(Youn Jin Cho),홍현준(Hyun Jun Hong) 대한두경부종양학회 2020 대한두경부 종양학회지 Vol.36 No.2

Neck mass has various etiologies, including inflammatory, congenital, neoplastic causes. The IgG4-related disease can cause symptoms in the head and neck areas with an inflammatory neck mass. It also shows clinical and pathological findings from inflammation caused by immune reactions, such as lymphocyte and plasma cell infiltration, storiform fibrosis, obliteration phlebitis, and invigorated serum IgG4 levels. The treatment guideline has not been established and still under debate, but systemic glucocorticoid seems to be effective in the most cases. In this brief report, a 48-year-old male patient presented with voice change for 3 weeks. Left side paramedian vocal fold palsy was observed in the flexible laryngoscopy. About 2.5X2.0X1.2cm size, heterogeneously enhanced neck mass with irregular margin encasing left carotid artery was noted on preoperative contrast enhanced neck CT scan, and it was suspicious of left carotid body tumor. The pathology shows IgG4-related disease rather than carotid body tumors. We report this case of IgG4-related disease, which can be misdiagnosed to carotid body tumors.

황재형,신경훈,이성기,송지선,권지원,Jae Hyeong Hwang,Kyung Hoon Shin,Sung Ki Lee,Ji Sun Song,Ji Won Kwon 대한안과학회 2012 대한안과학회지 Vol.53 No.12

Purpose: To provide a case report of 1 patient (1 eye) who experienced recurrences of conjunctival papilloma and was treated with complete resection, electrocauterization, cryotherapy, intraoperative application of mitomycin C and postoperative topical mitomycin C. Case summary: We evaluated the clinical course of a 42-year-old male with recurrent conjunctival papillomas on the left upper and lower tarsal conjunctiva who was treated 10 times with a simple resection over the past 8 years. The patient was treated with complete resection, electrocauterization, intraoperative application of mitomycin C and cryotherapy. Topical mitomycin C was applied for 1 month. There was no recurrence or complications for 12 months postoperatively. Conclusions: Complete resection, electrocauterization, intraoperative application of mitomycin C, cryotherapy and topical mitomycin C in patients with recurrent conjunctival papilloma was shown to be an effective treatment without recurrence and complications.

문민선,이혜경,정희선,송지선,Moon, Min-Seon,Lee, Hye-Kyung,Jeong, Hii-Sun,Song, Ji-Sun 대한성형외과학회 2010 Archives of Plastic Surgery Vol.37 No.6

Purpose: Basal cell nevus syndrome (BCNS), also known as Gorlin syndrome, is a rare autosomal dominant disorder. It is characterized by complex neoplastic syndrome with multisystemic manifestations, involving six major features. This article presents a rare genetic disorder and usage of the author's methods for odontogenic keratocyst, developed in the maxillary sinus. Methods: A 67-year-old man was presented with large calcified maxillary mass and multisystemic manifestations and findings that matched with basal cell nevus syndrome. The calcified maxillary mass was removed via the versatile maxillary window and maxillary bone segment was repositioned. Results: Histopathologic findings revealed that maxillary and mandibular lesions were odontogenic keratocysts and the skin lesions were basal cell carcinoma. Conclusion: Basal cell nevus syndrome is a rare genetic disease that requires surveillance and care for basal cell carcinoma and multisystemic problems. The author's method was satisfactory for maxillary odontogenic keratocyst in the aspect of the approach and reconstruction.

막증식사구체신염은 혈관사이바탕질, 내피밑층의 면역침착물의 증가와 사구체 기저막의 이중윤곽을 특징으르 하는 증식성 일차성 사구체신염이다. 막증식사구체신염에서의 사구체 침범은 주로 미만성이지만, 초점성 또는 분절성의 막증식사구체신염이 몇몇 발표되었다. 그러나, 우리나라에서는 아직 발표된 예가 없어서 이에 저자들은 5세 여아에서 3년 동안 저보체혈증 및 현미경적 혈뇨와 단백뇨를 보인 초점분절 막증식사구체신염 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Membranoproliferative glomerulonephritis (MPGN) is a progressive primary glomerulonephritis characterized by mesangial proliferation with increased mesangial matrix, subendothelial immune deposits, mesangial interposition and a double contour feature of the glomerular basement membrane. The glomerular involvement in MPGN is usually diffuse, however, cases of focal or segmental MPGN have been reported by several authors. We report a case of focal segmental MPGN with prolonged hypocomplementemia for ,3 years in a 5 years old girl. (J Korean Soc Pediatr Nephrol 2005;9:237-244)

저자들은 이전의 보고와 달리 알레르기의 과거력이 없으면서 ANA 양성을 보인 6세된 여아에서 아급성 괴사성 림프절염 1례를 경험하였기에 주로 자가 면역 질환과의 관련성에 대한 최근의 문헌 고찰과 함께 보고하는 바이다. Since the first description of Kikuchi disease(Subacute necrotizing lymphadenitis) in Japan, 1972, this condition has been reported in a worldwide. The etiology remains unknown. This disease shows a marked predilection for young woman, and a few cases in children has been reported. The usual initial clinical manifestation is localized cervical lymphadenopathy with fever, weight loss and myalgia. We experienced a 6 year-old girl of subacute necrotizing lymphadenitis with ANA, therefore report a brief review with the related literatures.
