Abstract
We herein report a case of type I congenital cystic adenomatoid malformation of the lung (CCAML) with non-immune hydrops fetalis (NIHF), a mediastinal shift and polyhydramnios diagnosed at 24 weeks' gestation by ultrasonography. The fetus was treated with a cyst-amniotic shunt at 29 weeks' gestation. Following a postnatal whole resection of the right lung, postpneumonectomy syndrome appeared and, as a result, the infant died 13 months after delivery due to respiratory failure. Only 19 cases demonstrating CCAML associated with NIHF have been reported previously in Japan. Four cases showed a spontaneous resolution of NIHF, while 5 cases with type I CCAML, which all underwent fetal intervention, demonstrated an excellent outcome.

Abstract
The authors report the case of a 2-year-old girl with pulmonary cystic adenomatoid malformation type II who presented with a mass on the lower lobe of the left lung. Resection and histological examination revealed pleomorphic rhabdomyosarcoma. Chemotherapy and radiotherapy followed the operation and the girl is alive and in perfect condition 10 years after the operation. The literature on primary rhabdomyosarcoma of the lung in children is reviewed.

Abstract
Respiratory distress due to either medical or surgical causes occurs commonly in neonates. It is the most common cause of admission to a neonatal surgical intensive care facility in a tertiary care hospital. The distress can be caused by a variety of clinical conditions; common conditions treated in medical intensive care units are transient tachypnea of the new born, respiratory distress syndrome, pulmonary air leak and pneumothorax. In surgical causes of respiratory distress in neonates the underlying mechanisms include airway obstruction, pulmonary collapse or displacement and parenchymal disease or insufficiency; the common causes are congenital diaphragmatic hernia, congenital cystic adenomatoid malformation, congenital lobar emphysema and esophageal atresia with or without tracheo-esophageal fistula. Obstructive lesions of the new born airway include choanal atresia, macroglossis, Pierre-Robin syndrome, lymphangioma, teratoma or other mediastinal masses, cysts, subglottic stenosis and laryngo tracheomalacia. Imaging plays a very major role in the pre-operative diagnosis of these conditions and proper pre-operative resuscitation helps in improving the results of surgery dramatically.

Abstract
OBJECTIVE We evaluated the outcome of fetuses diagnosed with having congenital cystic adenomatoid malformation (CCAM) on ultrasonographic examination and managed conservatively. METHODS A retrospective study of 19 cases of CCAM diagnosed antenatally in our hospital was conducted between 1990 and 2001. Complete clinical information was available for all patients, with a mean follow-up of 62 months. RESULTS The median gestational age at which CCAM was diagnosed was 23 weeks and there were eight live births. With conservative postnatal management, seven neonates had no major complications and one developed bronchopneumonia. CONCLUSION Taken together, the findings of the present study and a review of the literature strongly support the conservative management of selected neonates with CCAM.

Abstract
Cystic adenomatoid malformation is an uncommon embryonic developmental abnormality usually diagnosed in neonates and infants. Its presentation in adulthood is rare, with only 27 cases reported up to now. Due to its rarity, it is seldom suspected and adult physicians are not familiar with its clinical and radiologic features. We report two cases of cystic adenomatoid malformation presenting in adults, one as a recurrent pneumonia, and another as a coincidental finding on a chest roentgenogram. We describe the clinical features, radiologic and computed tomographic findings, and the histopathologic characteristics in this article, along with a review of the literature.

Abstract
Pleuropulmonary blastoma (PPB) was defined in 1988 by Manivel et al. in a series describing 11 intrathoracic pulmonary neoplasms in young children. The PPB is a unique peripheral pulmonary or pleural-based tumor of childhood that is characterized in its earliest form as a bland-appearing multiloculated cyst with small foci of tumor cells and in later forms as mixed and predominantly primitive, overtly malignant neoplasms. Prior to the introduction of the PPB as a distinct entity, this tumor had been reported in the literature as pulmonary blastoma, sarcoma arising in mesenchymal cystic hamartoma, embryonal sarcoma, malignant mesenchymoma, primary pulmonary rhabdomyosarcoma and rhabdomyosarcoma arising in congenital adenomatoid malformation or bronchogenic cyst. Over the past 15 years, PPB has come to be recognized in centers around the world. With the establishment of the Pleuropulmonary Blastoma Registry by Jack Priest, MD, and colleagues, there has been improved understanding of this rare pediatric neoplasm.

Abstract
Congenital cystic adenomatoid malformation of the lung is rare in adults. We present a 51-year-old man with recurrent lower respiratory tract infections and intermittent febrile episodes for more than 10 years. Multiple cavitary lesions with fluid accumulation were seen in the right lower lobe of the lung on radiography and computed tomography of the chest. Wedge resection of the right lower lobe of the lung was performed through a mini-thoracotomy using video-assisted thoracoscopy. Multiple infected cysts were found in a 10 x 8 x 6 cm area of lung. The histologic diagnosis was infected type I congenital cystic adenomatoid malformation. The patient remains well 1 year after the operation.

Abstract
As far as the prognosis is concerned, it is important to diagnose the exact type of congenital cystic adenomatoid malformation (CCAM) in order to exclude associated anomalies, as well as the risk of development of malignancies in later life. The frequency of associated malformations of CCAM type 4 is unknown. We report a 4-month-old boy with CCAM type 4 and aneurysmal malformation of the vein of Galen (AVG). Although AVG is the most frequent arteriovenous malformation during childhood, this is the first case report, to our knowledge, of CCAM type 4 in association with an anomaly. In addition, we speculate that the relation between CCAM type 4 and AVG appears to be more likely a possibly related association rather than a rare coincidence, as both malformations develop at the same stages of embryonic life, and pathogenetically, apoptosis play a significant role in both entities. However, further studies are needed to validate this speculation placing emphasis on the association of the two anomalies, otherwise a rare coincidence cannot be excluded.

Abstract
We present a surgically proven case of infradiaphragmatic pulmonary sequestration combined with cystic adenomatoid malformation. Prenatal magnetic resonance imaging revealed a well-defined hyperintense mass with a hypointense septum in the left infradiaphragmatic region. Postdelivery computed tomography (CT) and 3-month follow-up CT showed replacement of intralesional cystic areas by solid content. Such unusual postnatal CT changes, to our knowledge, have not been previously documented.

Abstract
Although adrenomedullin (ADM) is a potent vasodilating peptide reported to play a possible role in the mechanisms of fetal lung differentiation and maturation, the ADM blood level in fetuses and in neonates with persistent pulmonary hypertension (PPHN) and pulmonary hypoplasia is not known. Therefore, we examined 15 patients with PPHN: 10 with congenital diaphragmatic hernia, four with congenital cystic adenomatoid malformation of the lung, and one with misalignment of pulmonary vessels with alveolar capillary dysplasia. Eight surgical patients with neonatal conditions such as intestinal atresia served as controls. Blood samples were drawn from the umbilical artery and vein at birth, and arterial blood was drawn from patients with PPHN on the 3rd and 6th days after birth. Plasma levels of ADM were measured by radiometric assay. Plasma levels of ADM in the umbilical artery and vein were elevated in patients with PPHN compared with controls, and in all groups the levels in the umbilical vein were higher than those in the umbilical artery. The arterial levels in patients with poor prognoses were elevated on the 3rd and 6th days after birth compared with those in survivors. These results indicate that ADM may be involved in the pathophysiology of PPHN and in the mechanisms of lung differentiation and/or maturation.

Abstract
UNLABELLED Diagnosis and treatment of congenital respiratory cystic dysplasias - more complicated than acquired pulmonary diseases. In 20% of cases treatment should be started in newborn age because of respiratory distress syndrome. MATERIAL AND METHODS During the period of 1990-2002 we have diagnosed and treated 30 patients due to congenital respiratory cystic dysplasias. Clinical symptoms, diagnostic methods, indications for the operation and results of the surgical treatment were analyzed. RESULTS We operated on 18 boys and 12 girls. Age of the patients - 6 newborns, 8 infants, 3 children from 1 till 3 years, 13 patients from 7 till 15 years. Lobectomy was performed for 13 patients, segmentectomy in 1 case, and removal of the cyst in 14 cases. In 1 case videotoracoscopy and in 1 case angiography was made. All patients survived. Other diseases were found in 16 cases. CONCLUSIONS Congenital respiratory cystic dysplasias are serious respiratory disease of newborns and children which can cause respiratory distress syndrome. 1. Because of respiratory distress, possible infection and malignant transformation surgical treatment is recommended. 2. Antenatal diagnosis of congenital respiratory cystic dysplasias could enable the neonatologist and surgeon to prepare for the treatment, because in 20% of cases the treatment is necessary in early postnatal period.

Abstract
Extralobar sequestration is a congenital acquired disease more frequently observed after birth or during infancy. In half of the cases, it is associated with another malformation. In the following case we report the observation of a 24-year-old female with right extralobar sequestration associated with a diaphragmatic hernia and containing gastric mucosa and a congenital cystic adenomatoid lung malformation. Such malformative lung tissue is known to potentially degenerate and justifies surgery even when patients are asymptomatic.

Abstract
Pulmonary sequestration and congenital cystic adenomatous malformations (CCAM) are well known but still uncommon anomalies of the lung. Extralobar sequestrations are well described in association with CCAM, but fewer intralobar lesions are found with this association. The existence of striated muscle within CCAM is described, and we have evidence of dysplastic changes within the various cellular components occurring, with rhabdomyomatous dysplasia being one of these. A literature review shows no previous evidence of a reported intralobar sequestration associated with CCAM and rhabdomyomatous dysplastic changes.

Abstract
A congenital cystic adenomatoid malformation (CCAM) is a congenital lung lesion that, when associated with hydrops, is thought to have a dismal prognosis without fetal intervention. The authors report a case of a fetus with a CCAM associated with ascites as the only manifestation of hydrops, which was diagnosed at 19 weeks gestation. The CCAM regressed without intervention between 23 and 29 weeks of gestation with resolution of the ascites. The baby was born asymptomatic at term, and the infant underwent elective resection of the CCAM at 1 year of age. A review of the literature from 1980 to 2000 yielded 9 other cases of spontaneous resolution of hydrops associated with CCAM, suggesting that although rare, this outcome is a possibility in fetuses diagnosed with the condition. Because most fetuses diagnosed with hydrops undergo termination of pregnancy, the true incidence of hydrops resolution is potentially higher than predicted. This has important implications for prenatal counseling particularly in centers in which fetal intervention is not available.

Abstract
The purpose of this study was to review cases of congenital cystic adenomatoid malformations (CCAMs) arising in children and adults, in order to assess the recently expanded classification system for these lesions and their association with malignant transformation. Of 28 CCAMs, there were 16 type 1, 4 type 2, and 8 type 4 lesions, 12 of which presented in adults. Five of 16 type 1 CCAMs were accompanied by microscopic foci of bronchioloalveolar carcinoma; two others showed focal mucous cell hyperplasia. In two further cases, foci of nonmucinous atypical adenomatous hyperplasia were identified in the adjacent lung parenchyma. The bronchioloalveolar carcinomas showed less cytologic atypia, proliferative activity (Ki-67), and p53 expression than a comparative group of bronchioloalveolar carcinomas arising de novo, but this was not statistically significant (p = 0.15). Neither bronchioloalveolar carcinomas nor hyperplasia was identified in type 2 or type 4 CCAMs. Four of the eight type 4 CCAMs showed focal stromal hypercellularity, and one case subsequently developed a pleuropulmonary blastoma. We conclude that classification according to the current system is of clinical value. Bronchioloalveolar carcinomas arise in association with type 1 CCAMs, but recurrence following resection is exceptional. Type 4 CCAMs show histologic overlap with grade 1 pleuropulmonary blastomas, and distinction between these entities may not be possible on histology alone. However, stromal cellularity in a type 4 CCAM should raise the possibility of blastomatous transformation.

Abstract
Congenital cystic adenomatoid malformation of the lung can be detected with antenatal ultrasound as hyperechogenic areas in the fetal chest. Associated extrapulmonary malformations as well as chromosomal aberrations are described as very rare. We present a case report of a fetus in the 23rd week of gestation who showed in the course of a routine ultrasound screening a large number of malformations: holoprosencephaly, arrhinencephaly, cleft palate, CCAM type III of the right inferior pulmonary lobe, ventricular septal defect and bilateral clubfeet. Chromosome analysis confirmed the suspicion of trisomy 13. The present case shows how important it is-even with malformations that are rarely accompanied by associated anomalies and which have a very good prognosis-to carry out a directed diagnosis including a fetal karyotyping.

Abstract
BACKGROUND/PURPOSE Development of hydrops fetalis in fetuses with congenital cystic adenomatoid malformations (CCAM) is a significant risk factor for fetal or neonatal demise. In rare cases, resolution of CCAM has occurred, presumably owing to lesion maturation or involution. Steroid therapy, utilized for lung maturity, has been postulated to accelerate this process. The natural history of hydropic fetuses with CCAM after receiving steroid therapy is presented. METHODS The authors prospectively followed up with 3 patients who had antenatally diagnosed CCAM and nonimmune hydrops fetalis with predicted mortality. All patients declined or were not candidates for fetal intervention and were treated with standard prenatal betamethasone to increase lung maturity. RESULTS Three fetuses had CCAM and nonimmune hydrops fetalis diagnosed prenatally. After a course of prenatal steroids during the second trimester, all 3 patients had resolution of their hydrops and were delivered at term without respiratory distress. CONCLUSIONS Nonimmune hydrops fetalis in fetuses with congenital cystic adenomatoid malformation is a harbinger for fetal demise. The resolution of hydrops in these patients after receiving steroid therapy is an interesting and compelling observation. Because the mechanism of this process is speculative, further studies are needed to elucidate the relationship between antenatal steroids and maturation of congenital cystic adenomatoid malformation.

Abstract
For safer and simpler neonatal ECMO management, the authors have been developing an innovative, automatically-controlled ECMO machine using self-regulating blood pumps. The newest model is an air-driven, tube-type blood pump. A pair of blood pumps are placed in parallel and actuated alternately with compressed air. The pump flow is automatically regulated in accordance with hemodynamic changes of the body. The need for a venous reservoir is eliminated because the circuit does not generate excessive negative pressure when there are shortages of draining blood. Therefore, the priming volume of the circuit is only 85 ml. This ECMO apparatus has three driving modes, one of which is a "delay" mode. This enables the pump flow to easily be varied from 10 to 500 ml/min under automatic control, and it can be used when the pump flow is decreased for weaning. This newest ECMO apparatus was clinically used in 3 neonates with severe lung hypoplasia and persistent fetal circulation. The ECMO duration was 139 h to 168 h, and the maximum ECMO flow 71.3 to 109.0 ml/min/kg. Thanks to the self-regulation, intensive observation of the circuit was not necessary during ECMO. Damage to blood cells was less significant, and the use of blood products was only minimal (15.7 ml/kg/day) because a large volume of blood to stabilize the pump performance was not necessary. In conclusion, the automatically-controlled ECMO apparatus worked well without complications by changing the ECMO flow automatically in accordance with hemodynamic changes. This automatic ECMO system required fewer personnel expenditures and was also favorable in terms of hematological findings.
