Primitive neuroectodermal tumors(PNETs) are a group of small round cell tumors that may arise in the central or peripheral nervous system. In the extracranial location, these neoplasms may occur anywhere and at any age group, but most likely in the bone and soft tissue of children and young adults. The incidence of adrenal gland involvement is very rare. This tumor... |
Neonatal alloimmune thrombocytopenia(NAIT) is a very rare disease caused by maternal alloantibodies` response to neonatal platelet antigens. Because the most common cause of NAIT is incompatibility for platelet-specific antigens, NAIT cases due to anti-HLA antibodies are very exceptional. The patient was a second born female. She had no petechia or purpura at birth. But her platelet count was 55,000/mm3 and... |
Autoimmune thrombocytopenia and autoimmune hemolytic anemia occur in 10-26% of patients with systemic lupus erythematosus(SLE). These hematological manifestations may be the sole presenting sign and can precede the appearance of diagnosable SLE in 5 to 23% of cases. The conventional treatment for SLE associated with these disorders includes corticosteroid therapy and splenectomy, but autoimmune thrombocytopenia or autoimmune hemolytic anemia may... |
Lymphangiomatosis, a benign tumor consisting of a cluster of dilated lymphatic channels, is very unusual. Most lymphangiomatoses are found in the neck and head area. Less than 5% are diagnosed intraabdominally and they are very infrequently encountered in the retroperitoneal area. Herein, we report a rare case of asymptomatic lymphangiomatosis of a 13 year-old boy during a routine chest... |
Wernicke,s encephalopathy(WE), a neurological disorder caused by thiamine deficiency, is characterized by the triad of ocular symptoms, ataxia, and mental confusion. More than 90% of the cases are observed in chronic alcoholics. Other conditions less frequently associated with WE are anorexia nervosa, prolonged parenteral nutrition, hemodialysis, uremia, hyperemesis gravidarum, gastroplasty for morbid obesity, and acquired immunodeficiency syndrome(AIDS). One of the... |
Mesenteric lymphangioma, which is rare and often diagnosed incidentally, is a benign tumor in infants and children. Most cases of lymphangioma are in the neck and axilla. About 5% of these lesions are in the mediastinum, mesentery or retroperitoneal region. Although most lymphangioma produce no symptoms, it may present an acute surgical condition suggesting acute intestinal obstruction. We report one... |
Hypoglossia-hypodactylia syndrome is a congenital disease which is characterized by severe micrognathia, hypoglossia and various anomalies of extremities. This was first reported as 'aglossia congenita' back in 1932 by Rosenthal, and has been reported many times ever since, but has never been reported in Korea. Hall first used the term 'hypoglossia-hypodactylia syndrome', and classified it as one of the oromandibular-limb... |
Enterovirus 71(EV71), like polioviruses, invades the central nervous system to give rise to aseptic meningitis, encephalitis or myelitis. EV71 was first isolated in California in 1969 from a 9-month- old infant with encephalitis. Since then it has been isolated from the brain of children who died of encephalitis and from feces of patients with meningitis, encephalitis or paralysis. Related strains... |
Hyper-IgE syndrome is a rare congenital immune deficiency disease characterized by severe eczema, recurrent infection of the sinopulmonary tract, cold subcutaneous abscess and high serum IgE levels. It is an autosomal dominant disease with incomplete penetrance. We examined the case of a 12 month old infant with hyperIgE syndrome since neonate. The diagnosis of hyper IgE syndrome was made because... |
Hyperornithinemia-hyperammonemia-homocitrullinuria(HHH) syndrome is a rare autosomal recessive disorder caused by a defect in the urea cycle. Protein intolerance, mental retardation, seizure, ataxia, and stupor are characteristic symptoms. Patients showing these symptoms may also present symptoms of acute hepatic disease at the same time. When fed with a high protein diet, they may refuse to eat, vomit, become lethargic, or go... |
Fanconi-Bickel syndrome is a rare autosomal recessive disorder of the carbohydrate metabolism recently demonstrated to be caused by mutations in GLUT2, the gene for the glucose transporter protein 2 expressed in the liver, pancreatic β islet-cells, intestine and kidney. Typical clinical and laboratory findings of Fanconi-Bickel syndrome are hepatomegaly secondary to glycogen accumulation, glucose and galactose intolerance, fasting hypoglycemia, a... |
We report the case of a 4 year-old boy with Menetrier's disease, who was presented with edema and hypoalbuminemia. Gastroduodenal endoscopy showed the characteristic features of giant hypertrophy of the gastric rugae and large quantities of adherent gelatinous material. Histologic findings revealed foveolar hyperplasia. The presence of CMV infection was identified by serology. His symptoms resolved spontaneously, and he has... |
Annular pancreas is a rarely found gastrointestinal tract malformation, and is frequently associated with Down syndrome. Endocardial cushion defect is a type of congenital heart disease, commonly also related to Down syndrome. However, a combination of endocardial cushion defect with annular pancreas has not been reported previously. We recently experienced such a case in 2 month old boy. Moreover Down... |
Chondrodysplasia punctata is a heterogenous skeletal dysplasia characterized by small focal calcifications in articular and other cartilages in infancy, with subsequent epiphysial dysplasia and associated anomalies of the face, eyes, and skin. Chondrodysplasia punctata is classified with autosomal recessive rhizomelic type, autosomal dominant nonrhizomelic type(Conradi-Hunermann type), and X-linked dominant type. These types have different clinical manifestations respectively. We report cases... |
Childhood onset nemaline myopathy, first described in 1963 by Shy, et al and Conen, et al, is rare congenital myopathy, characterized by nonprogressive or slowly progressive muscle weakness associated with rod-like structures in muscle fibers, often with dysmorphic features. This myopathy was confirmed by muscle biopsy. The light microscopic features noted generally small round fibers that showed variation in size... |
Cutis laxa is a rare disorder of the elastic tissue characterized by loosely hanging and folded skin giving a premature senile appearance, often with internal organ involvement. Recently, we experienced a case of cutis laxa in a neonate. The patient who presented with dyspnea and loose skin at birth was delivered by Cesarean section in our hospital. He was the... |
The interstitial lung diseases(ILD) comprises a large, heterogeneous group of disorders characterized by derangement of alveolar walls and alveolar capillary unit causing restrictive pulmonary dysfunction and disordered gas exchange. It is rare, especially in children, and the opinions on investigation and treatments are controversial. The classification of adult ILD is applied to that of children. But considering occurrence during the developing state of lung... |
We report on two Korean siblings with multiple congenital anomalies : microcephaly, gyral abnormality, minor facial anomalies, and congenital nephrotic syndrome. The first infant developed proteinuria at age 3 days. This condition appeared similar to that described by Galloway and Mowat and reviewed by Cooperstone, et al, especially the presence of abnormal gyral patterns. She died at 19 months. The second infant; the brother... |
Cytomegalovirus(CMV) colitis is an important opportunistic infection in immunocompromised individuals. The clinical symptoms are abdominal pain, diarrhea, colonic hemorrhage and perforation. The endoscopic appearance shows three characteristic features with focal or diffuse inflammatory changes, submucosal hemorrhagic spots, and well demarcated ulcers. We experienced a case of CMV colitis in an 8-year-old girl presented with Stevens-Johnson syndrome, vanishing bile duct syndrome and infection-associated hemophagocytic histiocytosis, which... |
Ectopic pancreas is defined as being the presence of pancreatic tissue outside its usual or habitual location and without anatomic relation either of continuity or of vascularization with the pancreatic proper. The most common developing sites are the stomach(especially greater curvature of antrum), duodenum and proximal jejunum. Most lesions do not cause any clinical symptoms, but sometimes nonspecific significant symptoms... |
Intrathecal administration of methotrexate(IT-MTX) has constituted the standard approach to prophylaxis and treatment of central nevous system(CNS) leukemia. We experienced a quadriplegia and motor aphasia in a 14-year-old boy following repeated IT-MTX for the prophylaxis of meningeal leukemia. He was diagnosed as ALL without CNS involvement and treated by CCG- 1882 protocol. IT-MTX was administered for CNS prophylaxis. The patient began complaining of urinary incontinence,... |
Status epilepticus has been occasionally reported as a cause of acute disseminated intravascular coagulation(DIC), but little is known regarding the pathogenesis of this uncommon association. The occurrence of DIC in status epilepticus may be related to widespread endothelial damage secondary to seizure-induced hyperpyrexia or status epilepticus due to high fever. We experienced two cases of status epilepticus accompanying fever in which laboratory data demonstrated... |
Hereditary motor and sensory neuropathy type III, which is also known as Dejerine-Sottas disease, is a severe demyelinating polyneuropathy which presents from birth or infancy, and is sometimes presented as a hypotonic or floppy infant. The disease is inherited autosomal recessively and includes clinical findings of generalized muscle weakness and atrophy, with the greatest severity in distal limb muscles, areflexia, and sensory loss. The... |
Enteric duplications are uncommon congenital anomalies. Duplications of the stomach account for only 3.8% of gastrointestinal duplication. More particularly, duplications involving the pylorus are extremely rare. These are characterized by firm attachment to at least one point of the alimentary tract with a well developed coat of smooth muscle and mucous membrane. The most frequent presentation is an abdominal mass with vomiting, mainly discovered... |
Trisomy 9 mosaicism is a disease characterized not only by intrauterine growth retardation and mental retardation but also congenital heart defects, musculoskeletal, genitourinary and CNS anomalies, as well as craniofacial anomalies such as microcephaly, micrognathia, narrowed temples, prominent occiput, broad-based nose with bulbous tip, low set ears, deeply set eyes, short palpebral fissure and small mouth. This syndrome was first reported back in 1973... |
Vascular leak syndrome(VLS) is characterized by endothelial damage, which causes extravasation of plasma proteins and fluid from capillaries into the extravascular space. It has been suggested that the increased vascular permeability is the result of an IL-2-induced suppression of endothelin- 1 secretion by endothelial cells, an IL-2-induced activation of the complement cascade or TNF-αrelease from IL-2-activated T-cells. A 13-year-old male patient visited our hospital... |
This is a case report of multiple coil embolization for the diffuse pulmonary arteriovenous malformations( PAVM). PAVMs are direct communications between pulmonary arteries and pulmonary veins, resulting in an anatomic right-to-left shunt that may cause paradoxical embolization to may occur, resulting in neurologic complications such as stroke or cerebral abscess. The treatment of choice for solitary PAVMs was limited to surgical resection or ligation... |
Graves disease is the most common clinical feature of hyperthyroidism in childhood. Clinical manifestations include emotional lability, hyperactivity, tremor, excessive sweating, exophthalmos and weight loss. In Graves disease, osteoporosis could occur because of a disturbance of mineral homeostasis which rarely develops from reduced calcium absorption of the gastrointestinal tract and increased urinary calcium excretion related to an increased bone resorption.... |
Chondrodysplasia punctata is a rare congenital syndrome caused by a peroxisomal dysfunction. Chondrodysplasia punctata is classified into four main types-Coradi-Hunermann's type, rhizomelic type, X-linked dominant form and X-linked recessive form. A male patient with this condition was born at 39 weeks gestation, the pregnancy being complicated by polyhydroamnios, breech presentation, and anomalies of congenital limbs. At delivery, there was no... |
Malignant ectomesenchymoma is a rare tumor originating from remnants of migratory neural crest(ectomesenchyme) and composed of neuroectodermal as well as mesenchymal components. Neuroblasts and ganglion cells constitute the neuroectodermal components and rhabdomyosarcoma is the most frequently encountered mesenchymal components. We report a case of malignant ectomesenchymoma in a two-month-old boy who was presented with abdominal pain and urinary difficulty. The... |
