목 적: 융모 위축을 보이는 FPIES 환자의 소장 점막에는 TNF-${\alpha}$의 발현이 증가한다. TNF-${\alpha}$는 상피 세포의 세포 자렴사를 유발하는 것으로 알려져 있다. 저자들은 FPIES 병리생리의 특성을 알아보고자 십이지장 점막 조직에서 TNF family와 TNF-수용체 family의 세포 자멸사를 연구하였다. 방 법: 표준화된 경구 유발 시험을 통하여 FPIES로 진단된 15례의 환자와 5례의 대조군을 대상으로 연구하였다. 세포 자멸사를 확인하기 위하여 terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) 염색을 시행하였다. 세포 자멸의 기전을 알아 보기 위해 TNF family의 TNF-${\alpha}$, Fas ligand (FasL)와 TNF-수용체 family의 TNF-related apoptosis-including ligand (TRAIL) receptor 1 (DR4), TRAIL receptor 2 (DR5), Fas를 면역조직화학으로 염색하였다. 결 과: $TUNEL^+$ 세포는 대조군에 비하여 FPIES 환자군의 십이지장 점막에서 의미 있게 높게 발현하였다($P$=0.043). TNF-${\alpha}$ ($P$=0.0001)와 DR4 ($P$=0.003)도 대조군에 비하여 FPIES군에서 의미 있게 높게 발현하였다. FasL, Fas, DR5의 발현은 두 군 모두에서 낮았으며, 두 군간에 의미 있는 차이를 보이지도 않았다. 결 론: FPIES의 병리생리는 세포 자멸사에 의하여 발생하며, TNF-${\alpha}$의 발현과 DR4 경로가 세포 자멸사에서 중요한 역할을 하는 것으로 추정된다. Purpose : Expression levels of tumor necrosis factor (TNF)-${\alpha}$ expression on the mucosa of the small intestine is increased in patients with villous atrophy in food protein-induced enterocolitis syndrome (FPIES). TNF-${\alpha}$ has been reported to induce apoptotic cell death in the epithelial cells. We studied the TNF family and TNF-receptor family apoptosis on the duodenal mucosa to investigate their roles in the pathogenesis of FPIES. Methods : Fifteen infants diagnosed as having FPIES using standard oral challenge test and 5 controls were included. Terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) staining was performed to identify the apoptotic cell death bodies. Immunohistochemical staining of TNF-${\alpha}$, Fas ligand (FasL) for TNF family and TNF-related apoptosis-including ligand (TRAIL) receptor 1 (DR4), TRAIL receptor 2 (DR5), and Fas for TNF-receptor family were performed to determine the apoptotic mechanisms. Results : $TUNEL^+$ was significantly more highly expressed in the duodenal mucosa of FPIES patients than in controls ($P$-0.043). TNF-${\alpha}$ ($P$=0.0001) and DR4 ($P$=0.003) were significantly more highly expressed in FPIES patients than in controls. Expression levels of FasL, Fas, and DR5 were low in both groups and were not significantly different between the 2 groups. Conclusion : These results suggest that FPIES pathogenesis is induced by apoptosis, and that TNF-${\alpha}$ expression and DR4 pathway may have an important role in apoptosis.

주기성 구토증(cyclic vomiting syndrome)의 장기 추적 관찰 -이형 편두통(migraine variant)으로의 이행 과정인가?-

황진복,오희종,최광해,Hwang, Jin-Bok,Oh, Hee-Jong,Choi, Kwang-Hae 대한소아소화기영양학회 2000 Pediatric gastroenterology, hepatology & nutrition Vol.3 No.1

저자들은 주기성 구토증으로 진단된 3명의 소아에서 6년 이상의 장기 추적관찰을 통하여 임상양상의 다양한 변화과정을 관찰하여 보고, 뇌파검사의 이상소견을 근거로 이형 편두통의 형태로 진행하여 가는 과정을 관찰하였다. 시간의 경과에 따라 구토 발병 주기, 기간의 변화와 함께 위배출능 저하, 두통의 발현, 뇌파의 이상 등 다양한 임상 양상의 변화를 보여주며, 2례에서는 증상의 소실이 관찰되었다. 특히, 뇌파 검사상 증상 발현시 발생하는 서파는 편두통의 발생 직전에 뇌혈류의 감소로 발생하는 양상과 매우 유사하며, 주기성 구토증과 편두통의 관련성을 시사하여 주는 소견으로, 진단 및 치료적 접근시 반드시 고려하여야 한다. 주기성 구통증은 이형 편두통으로의 이행 과정인가? Cyclic vomiting syndrome(CVS) is a disorder of unknown etiology that is characterized by its clinical pattern of intermittent episodes of severe vomiting, similar in time of onset and duration, with no symptoms during the intervening period. By definition, CVS is an idiopathic disorder that requires exclusionary laboratory testing. Not only can it be mimicked by many specific disorders, eg, surgical, neurologic, endocrine, metabolic, renal, but within idiopathic CVS there may be specific subgroups that have different mechanisms. It has been reported that CVS usually begins in toddlers and resolves during adolescence. Migraine is also self-limiting episodic condition of children and the clinical features of migraine and CVS show considerable similarity. It is proposed that CVS is a condition related to migraine. This paper reports clinical courses of long term follow-up and reversible EEG changes in three patients whose history included CVS. Clinical situations of attack interval, duration and associated symptoms had changed variablely in each patients through long term follow-up period. Cyclic vomiting subsided in two cases. Abnormal delta activity was seen during episodes and resolved at follow-up, when the patient asymptomatic. The brain wave changes support the interpretation of CVS as a migraine variant.

식품 단백질 유발성 장염 증후군: 임상적 접근과 병태생리의 최신 지견

황진복,Hwang, Jin-Bok 대한소아소화기영양학회 2007 Pediatric gastroenterology, hepatology & nutrition Vol.10 No.2

Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE mediated hypersensitivity disorder, which is associated with mainly gastrointestinal symptoms and has a delayed onset. The vomiting and/or diarrheal symptoms of FPIES typically begin in the first month of life in association with a failure to thrive, metabolic acidosis, and shock. Therefore, the differential diagnosis of FPIES and neonatal or infantile sepsis-like illnesses or gastroenteritis is difficult. The early recognition of indexes of suspicion for FPIES may help in the diagnosis and treatment of this disorder. The diagnosis of FPIES is generally made through clinical practice and food-specific IgE test findings are typically negative in this condition. Therefore, oral cow's milk challenge (OCC) remains the valid diagnostic standard for FPIES. An investigation of positive OCC outcomes helps to find out a diagnostic algorithm of criteria of a positive challenge in FPIES. Moreover, it has not been clearly determined in infantile FPIES when $1^{st}$ follow up-oral food challenge (FU-OFC) should be performed, with what kind of food protein (e.g., cow's milk, soy), and how much protein should be administered. Hence, to prevent the risk of inappropriate FU-OFC or accidental exposure and achieve appropriate dietary management, it is necessary to identify tolerance rates to major foods under the careful follow up of infantile FPIES patients. On the other hand, small intestinal enteropathy with villous atrophy is observed in FPIES and this enteropathy seems to be in part induced by both of epithelial apoptosis and intercellular junctional complex breakdown. The purpose of this report is to introduce an update on diagnostic and therapeutic approaches in FPIES and suggest the possible histopathological evidences in this disorder.

황진복,최선윤,권태찬,오훈규,감신,Hwang, Jin Bok,Choi, Seon Yun,Kwon, Tae Chan,Oh, Hoon Kyu,Kam, Sin 대한소아소화기영양학회 2004 Pediatric gastroenterology, hepatology & nutrition Vol.7 No.1

목 적: 효율적인 진단과 치료 및 적절한 의학적 교류를 목적으로 소아 위장관 알레르기 질환의 새로운 분류법이 발표되었다(J Pediatr Gastroenterol Nutr 2000;30:S87-94). 그러나 명칭과 분류의 변경으로 이미 알려진 질환들이 새로운 질환으로 보고되기도 하는데, 저자들은 새로운 분류법에 따른 소아 위장관 알레르기 질환의 질병군에 관하여 알아보고, 국내에서 이미 보고된 관련 문헌을 함께 고찰하여 의학적 교류에 혼선을 최소화 하고자 한다. 방 법: 2003년 3월부터 7월까지 계명대학교 의과대학 소아과를 방문하여, 우유 유발 및 제거시험, 내시경을 이용한 조직생검 등을 이용하여 소아 GI-CMA로 진단된 37례(남 19, 여 18)를 대상으로 후향성 조사하였다. 새로운 분류에는 포함되지 않았으나 위식도역류 관련 알레르기를 추가하였다. 국내 문헌은 소아과학회지, 소아소화기영양학회지, 소아알레르기호흡기학회지를 근거로 고찰하였다. 결 과: 1) 대상 환아의 연령은 2주~15개월, 평균 $5.4{\pm}4.8$개월이었다. 2) 출생체중은 전례에서 10~90백분위수를 차지하였으며, 25~75백분위수가 25례(68%)를 차지하였다. 내원 당시 체중은 3백분위수 이하가 18례(49%)이었다. 3) 증상발현에서 진단까지 걸린 시간은 2주~12개월, 평균 $2.4{\pm}3.3$개월이었다. 4) IgE 군인 IgE 매개형 우유알레르기(IGE) 6례(16%), IgE와 Non-IgE 혼합군인 호산구성 위장관염(EOS) 2례(5%), Non-IgE군인 전형적 우유 단백질 유발 장관염(CMPIE-T) 7례(19%), 비전형적 우유 단백질 유발 장관염(CMPIE-AT) 5례(14%), 알레르기성 대장염(AC) 12례(32%)이었다. 위식도역류증 관련 우유 알레르기(GERA)는 5례(14%)이었다. CMPIE-T 전례에서 소장 조직생검상 장병증이 관찰되었다. 5) 진단 당시 연령은 IGE $4.3{\pm}0.8$개월, EOS 생후 2주와 14개월, CMPIE-T $3.8{\pm}4.6$개월, CMPIE-AT $10.4{\pm}3.8$개월, AC $3.4{\pm}3.9$개월, GERA $7.8{\pm}5.7$개월로 질환군간 유의한 차이를 보였다(p<0.05). 6) 내원 당시 3백분위수 이하를 보인 경우가 IGE 17%, EOS 0%, CMPIE-T 86%, CMPIE-AT 60%, AC 25%, GERA 100%로 질환군간 유의한 차이를 보였다(p<0.05). 7) 국내 문헌을 고찰하여 소아 위장관 우유 알레르기 질환은 만성설사, 난치성설사, 우유 불내성, 우유 알레르기, 위장관 알레르기, 우유 과민성 장병증, 호산구성 위장관염, 알레르기성 대장염 등의 용어로 보고되었다. 결 론: 새로운 분류법에 따른 소아 위장관 우유 알레르기 질환은 연령, 임상 증상, 위장관 침범 부위에 따라 특징적인 유형으로 구분할 수 있으며, 임상적으로 드물지 않다. 국내의 문헌을 통하여 다양한 용어로 각 유형의 알레르기 질환들은 연구 보고되어 왔다. Purpose: A new classification of gastrointestinal food allergy was published, but the changes of terminology between previously reported terms and the new ones were in a state of disorder. This has resulted in confusion between medical communication and diagnostic and therapeutic approaches. The clinical observations of infants presenting with gastrointestinal cow milk allergy (GI-CMA) were performed, and the changes in the terminology reviewed through the published Korean literature. Methods: Between March 2003 and July 2003, data from 37 consecutive infants with GI-CMA, aged 2 weeks to 15 months, were reviewed. The challenge and elimination test of cow milk, and the endoscopic and histologic findings, were used for the seven subdivisions of GI-CMA according to a new classification on the basis of patients' ages, clinical manifestations and location of gastrointestinal lesions. Results: The 37 patients had a mean age of $5.4{\pm}4.8$ months, with those observed in 26 (70.3%) of patients being below 6 months of age. The seven final diagnoses were; cow milk protein-induced enterocolitis (CMPIE) in 12 (32.4%), cow milk protein proctitis (PROC) in 12 (32.4%), IgE-mediated (IGE) in 6 (16.2%), gastroesophageal reflux-associated cow milk allergy (GERA) in 5 (13.5%) and eosinophilic gastroenterocolitis in 2 (5.4%). CMPIE was revealed as the typical type in 7 (18.9%) and the atypical type in 5 (13.5%), and all of typical CMPIE revealed cow milk protein-induced enteropathy. The mean age at symptom onset was $4.3{\pm}0.8$ months, and for those with typical and atypical CMPIE, and PROC and GERA were $3.8{\pm}4.6$, $10.4{\pm}3.8$, $3.4{\pm}3.9$ and $7.8{\pm}5.7$ months, respectively (p<0.05). The period from onset of symptom to diagnosis was $2.4{\pm}3.3$ (0.5~12) months, with those observed in atypical CMPIE and GERA being over 3months. Although the birth weights in all patients were within the 10~90 percentile range, the body weights on diagnoses were below the 3 percentile in 48.6%; IGE 16.7%, EOS 0%, typical CMPIE 85.7%, atypical CMPIE 60.0%, PROC 25.0% and GERA 100% (p<0.05). Through the review of the Korean literature, 8 case reports and 14 original articles for GI-CMA were found. Conclusion: GI-CMA is not a rare clinical disorder and is subdivided into seven categories on the basis of the patient's age, clinical manifestations and location of the gastrointestinal lesions. The terms for GI-CMA are changing with new classifications, and careful approaches are necessary for medical communications.

우유 과민성 장병증(cow's milk-sensitive enteropathy)에서 소장 생검조직의 형태학적 계측을 이용한 정량적 분석

황진복,김용진,Hwang, Jin-Bok,Kim, Yong-Jin 대한소아소화기영양학회 1998 Pediatric gastroenterology, hepatology & nutrition Vol.1 No.1

목 적: 우유 과민성 장병증(cow's milk-sensitive enteropathy, CMSE)은 우유를 식이 하였을 때 유해 반응과 함께 발생하는 상부 소장 점막의 손상이 병리적 특징으로 관찰되며, 이러한 점막의 손상은 우유를 제거하면 회복될 수 있고, 다시 유발시험을 하면 재발될 수 있다. CMSE 환자에서 소장 점막 손상의 정도를 형태학적 계측을 이용하여 정량적으로 분석하여 보고, 이를 이용한 CMSE의 진단적 가치 및 병리적 특성에 관하여 알아보고자 본 연구를 시행하였다. 대상 및 방법: 1994년 3월부터 1996년 6월까지 만성 설사와 성장 장애를 주소로 대구효성가톨릭 대학병원 소아과에 입원한 환자에서 우유에 대한 유발, 제거시험에 따른 임상적 반응 및 상부위장 관내시경을 시술하여 얻게 된 십이지장부의 생검조직 소견을 통하여 CMSE로 진단된 생후 $30.4{\pm}11.7$(14~56)일된 13명의 환아를 대상으로 하였다. 소장 생검조직의 형태학적 계측을 이용하여 융모 높이(villous height, VH), 음와 영역 깊이(crypt zone depth, CZD), 점막전체 두께(total mucosal thickness, TMT), 음와 영역에 대한 융모의 상대적 높이(VH/CD), 융모 1 mm당 상피세포간 림프구의 수(interepithelial lymphocytes, IEL), 0.5 mm의 점막근육판(muscularis mucosa)에 해당하는 상피 표면의 길이(length of surface epithelium, LSE), 상피층의 호산구 침윤(EOS-EP), 고유층(lamina propria)의 호산구 침윤(EOS-LP)을 측정하고, 대조군 및 회복기 생검 조직과 비교하였다. 결 과: 1) VH는 CMSE 환자군에서 $135{\pm}59\;{\mu}m$으로 대조군 $408{\pm}48\;{\mu}m$에 비하여 유의하게 낮았으며(p<0.001), 전례에서 융모 위축의 소견이 관찰되었다. 2) CZD는 CMSE 환자군에서 $311{\pm}65\;{\mu}m$으로 대조군 $188{\pm}24\;{\mu}m$에 비하여 유의하게 깊었다(p<0.05). 3) TMT는 CMSE 환자군에서 $449{\pm}56\;{\mu}m$으로 대조군 $596{\pm}71\;{\mu}m$에 비하여 유의하게 낮았다(p<0.001). 4) VH/CD는 CMSE 환자군에서 $0.46{\pm}0.28$로 대조군 $2.17{\pm}0.12$에 비하여 유의하게 낮았다(p<0.001). 5) LSE는 CMSE 환자군에서 $889{\pm}231\;{\mu}m$으로 대조군 $2547{\pm}378\;{\mu}m$에 비하여 유의하게 낮았다(p<0.001). 6) IEL은 CMSE 환자군에서 $34.1{\pm}10.5$개로 대조군 $13.6{\pm}3.6$개에 비하여 유의하게 높았다(p=0.001). 7) EOS-EP는 CMSE 환자군에서 $0.47{\pm}0.83$개로 의미 있는 침윤은 관찰되지 않았으며, 대조군 $0.80{\pm}0.84$개와 유의한 차이는 보이지 않았다. EOS-LP는 환자군에서 $2.67{\pm}3.72$개로 의미 있는 침윤은 관찰되지 않았으며, 대조군 $4.0{\pm}2.5$개와 유의한 차이를 보이지 않았다. 8) 회복기의 형태학적 변화는 VH $320{\pm}34\;{\mu}m$, CZD는 $194{\pm}19\;{\mu}m$, TMT $514{\pm}21\;{\mu}m$, VH/CD $1.41{\pm}0.25$, LSE $1840{\pm}210\;{\mu}m$, IEL $10.8{\pm}2.3$개로 관찰되었다. 결 론: 소장 조직의 생검은 상부위장관내시경을 이용하여도 그 임상적 유용성이 높으며, CMSE 환자에서 소장 점막의 손상은 형태학적 계측을 통하여 정량적으로 평가할 수 있으며 진단적 민감도가 높다. CMSE에서 점막의 손상은 빠른 융모 상피의 손상에 대한 음와 세포의 충분한 보상의 실패로 사료되며, 단백질 가수분해물의 수유후 빠른 회복이 관찰되었다. Purpose: To make objective standards of small intestinal mucosal changes in cow's milk-sensitive enteropathy (CMSE) we analyzed histological changes of endoscopic duodenal mucosa biopsy specimens from normal children and patients of CMSE. Methods: We review the medical records of patients who had been admitted and diagnosed as CMSE by means of gastrofiberscopic duodenal mucosal biopsy following cow's milk challenge and withdrawal. Thirteen babies with CMSE, ranging from 14 days to 56 days of age, were studied. Five non-CMSE patients were used as control, ranging from 22 days to 72 days of age. The morphometric parameters under study were villous height, crypt zone depth, ratio of villous height to crypt zone depth, total mucosal thickness and length of surface epithelium by using H & E stained specimens under the drawing apparatus attached microscope. In addition, the numbers of lymphocytes in the epithelium and eosinophil cells in the lamina propria and epithelium were measured. Results: In the duodenal mucosal biopsy specimens in CMSE we found partial and subtotal villous atrophy with an increased number of interepithelial lymphocytes. The mean villous height($135{\pm}59\;{\mu}m$), ratio of villous height to crypt zone depth ($0.46{\pm}0.28$), total mucosal thickness ($499{\pm}56\;{\mu}m$), length of surface epithelium of small intestinal mucosa ($889{\pm}231\;{\mu}m$) in CMSE was significantly decreased compared with the control (p<0.05). The mean crypt zone depth ($311{\pm}65\;{\mu}m$) was significantly greater than the control ($188{\pm}24\;{\mu}m$)(p<0.05). Infiltration of interepithelial lymphocytes ($34.1{\pm}10.5$) were significantly greater than the control ($13.6{\pm}3.6$)(p<0.05). The number of eosinophil cells in both lamina propria and epithelium was no significant differences between groups (p>0.05). The small intestinal mucosa in treated CMSE showed much improved enteropathy of villous height, crypt zone depth, interepithelial lymphocytes compared with the control as well as untreated CMSE. Conclusion: Quantitation of mucosal dimensions confirmed the presence of CMSE. It seems to be a limitation in the capacity of crypt cells to compensate for the loss of villous epithelium in CMSE. Specimens obtained by gastrofiberscopic duodenal mucosal biopsy were suitable for morphometric diagnosis of CMSE. Improvement of CMSE also can be confirmed histologically after the therapy of protein hydrolysate.

영유아 식품알레르기의 임상적 조망

황진복,Hwang, Jin-Bok 대한소아소화기영양학회 2011 Pediatric gastroenterology, hepatology & nutrition Vol.14 No.2

Food allergies affect 7~8% of infants and young children, and their prevalence appears to have increased in recent years. Food allergy refers to an abnormal immunological reaction to a specific food. These reactions can be recurrent each time the food is ingested. Food allergy manifests itself with a wide spectrum of clinical characteristics including IgE-mediated diseases as immediate reactions, non-IgE-mediated disorders as delayed reactions, and mixed hypersensitivities. As a consequence, the clinical picture of a food allergy is pleomorphic. A well-designed oral food challenge is the most reliable diagnostic test for infants and young children whose clinical history and physical examination point towards a specific food allergy. Food specific IgE antibody tests (RAST, MAST, skin prick test, Uni-CAP, etc) are an alternative tool to determine oral food challenge for IgE-mediated disorders, but not for non-IgE-mediated allergies. Moreover, parents often impose their children on unnecessary diets without adequate medical supervision. These inappropriate dietary restrictions may cause nutritional deficiencies. This review aims to introduce clinical perspectives of food allergy in infants and young children and to orient clinicians towards different strains of diagnostic approaches, dietary management, and follow-up assessment of tolerance development.

고지질 식이 투여를 이용하여 상부위장관내시경 소견으로 진단된 원발성 장림프관 확장증

권우현,황진복,이영환,김용진,Kwon, Woo-Hyun,Hwang, Jin-Bok,Lee, Young-Hwan,Kim, Yong-Jin 대한소아소화기영양학회 1999 Pediatric gastroenterology, hepatology & nutrition Vol.2 No.1

전신 부종을 주소로 내원한 20개월된 남아에서 대변의 ${\alpha}_1$-antitrypsin clearance를 이용하여 단백상실성 장병증으로 진단하고, 상부위장관내시경을 시행하였으나 육안적 및 조직학적 소견상 특기할 만한 진단적 실마리가 관찰되지 않아, 고지질 식이를 투여 후 내시경을 시행하여 육안적, 조직학적 소견상 장림프관 확장증의 특징적인 소견이 확인되어 원발성 장림프관 확장증으로 진단된 증례이다. We experienced a case of primary intestinal lymphangiectasia in a 20-month-old boy, which was confirmed gastrofiberscopically and histologically only after a high-fat meal before the procedure. A characteristic endoscopic finding was the appearance of tiny white dots scattered in the duodenal mucosa, which were proved dilated lymph vessels in the lamina propria on histological examination. Treatment with low-fat diet and medium chain triglycerides supplementation was satisfactory.

복강경 Nissen 위저추벽성형술 후 발생한 위배출지연에 대한 에리트로마이신의 유용한 효과 - 1예 보고-

정은영,황진복,최순옥,박우현,Jung, Eunyoung,Hwang, Jin-Bok,Choi, Soon-Ok,Park, Woo-Hyun 대한소아외과학회 2012 소아외과 Vol.18 No.1

Delayed gastric emptying (DGE) commonly occurs after Nissen fundoplication in patients with gastroesophageal reflux disease. Since the understanding of its pathogenesis is insufficient, an effective method of management has not yet been suggested. The authors report a case of a 16-year-old girl with DGE after laparoscopic Nissen fundoplication and treated with intravenous injection of low dose erythromycin.

토혈과 원통 모양의 토물을 주소로 내원한 Trichosporon beigelii 식도염 1례

박은정,황진복,안욱수,전창호,김용진,Park, Eun-Jung,Hwang, Jin-Bok,Ahn, Wook-Su,Jun, Chang-Ho,Kim, Yong-Jin 대한소아소화기영양학회 1999 Pediatric gastroenterology, hepatology & nutrition Vol.2 No.1

토혈과 함께 변성된 생체 조직의 일부로 보이는 토물을 주소로 내원한 소아에서 응급 상부위장관 내시경 시술을 이용하여 식도 부에서 유출된 토혈과 토물로 진단하고, 조직 검사를 이용하여 드문 원인 균인 T. beigelii에 의한 진균성 식도염으로 진단된 례를 경험하였다. 진균성 식도염에 의해 이미 형성되어 있던 가막성 조직은 변성된 식도 점막부의 상피 세포들로서 점막하 조직으로 부터 원통형으로 분리되었으며, 이때 발생한 구토에 의하여 토혈과 함께 토물로 배출된 희귀한 증례이다. We experienced a case of Trichosporon beigelii esophagitis in a 16-month-old boy who was presented with hematemesis with a large amorphous material. A spit-out material was silky, $10{\times}1.2\;cm$ in size and like a part of hollow viscus organ. Emergent gastrofiberscopy revealed that this silky material was teared up from upper and to lower esophagus and was threw with hematemesis. It was suggested that pseudomembrane on esophagus was peeled off followed by mucosal bleeding. Pathologic study revealed this material was pseudomembrane with esophageal mucosa of T. beigelii esophagitis and was teared at lamina propria level from submucosa.
