Abstract
Pulmonary glial heterotopia is an extremely rare entity whose pathophysiology remains unclear. We report for the first time one case of pulmonary glial heterotopia occured in a one-month baby free from any malformation. She has the particularity of being born from monozygotic monochorionic twin pregnancy where her anencephalic exencephalic sister suffered a medical termination of pregnancy. She presented neonatal respiratory distress, which recurred one month later. Chest X-ray revealed bilateral cystic pulmonary lesions mainly located in the right lung. Given the suspicion of congenital cystic adenomatoid malformation (CCAM), she underwent an upper and a lower right lung lobectomy at four months old. The pathological study found a multi-cystic lesion consisted of well-differentiated and poorly cellular glial tissue sometimes lined by bronchic epithelium. There was no pathological evidence for a CCAM. The evolution was favorable after surgery with an infant who was well five months later. This is one of the very few cases where the disease did not lead to rapid death in utero or during the perinatal period. This suggests that effective management by surgery could be a decisive factor in the survival of these patients.

Abstract
Neuroglial heterotopias (NGH) are rare congenital head and neck lesions composed of differentiated neuroectodermal tissue and representing developmental heterotopias rather than true neoplasms. The case of a male neonate with respiratory distress and early feeding problems depicting a retropharyngeal space mass which in the intraoperative squash smears revealed glial cells with multiple cytoplasmic processes is reported here. Small clusters of cuboidal epithelial cells with rosette-like ependymal structures and cuboidal cells arranged in sheets or branching folds suggestive of choroid plexus cells were also identified. Through this cytological approach a cytologic diagnosis of a NGH or low-grade astrocytoma was suggested. Further evaluation and immunohistochemical studies were conducted on formalin-fixed, paraffin-embedded material. Glial cells, ependymal structures and choroid plexus were identified on H&E sections. Immunohistochemically, the glial cells showed diffuse and strong cytoplasmic staining for glial fibrillary acidic protein (GFAP) and S-100 protein and focal immunoreactivity for synaptophysin and neurofilament. The proliferative index with MIB-1 was around 4%. The diagnosis of NGH of the retropharyngeal space was confirmed based on the clinical, cytopathologic, histopathology, immunohistochemical results, and the location of the tumor. We demonstrated here for the first time the cytopathological features of NGH of the retropharyngeal space with emphasis on differential diagnostic considerations.

Abstract
PURPOSE To investigate the proliferation and neuronal death in brain tissue heterotopia in the lung in an experimental model during both fetal and neonatal periods. METHODS Twenty four pregnant female Swiss mice were used to induce brain tissue heterotopia on the 15th gestational day. Briefly, the brain of one fetus of each dam was extracted, disaggregated and injected into the right hemithorax of siblings. Six of these fetuses with pulmonary brain tissue implantation (PBI) were collected on the 18th gestational day (group E18) and six other on the 8th postnatal day (group P8). Immunohistochemical staining for PCNA and Bcl2 were used to assess proliferation and cell death. RESULTS PCNA Labelling Index (LI) in heterotopic brain tissue was greater in fetal than postnatal period (E18 > P8) (p<0.05) and the immunostaining with Bcl2 antibody did not show difference. CONCLUSION Cell proliferation is maintained in brain tissue heterotopia, although apoptosis is also observed.

Abstract
We report on a male infant with extensive, bilateral cystic and solid lung lesions who presented postnatally with respiratory distress caused by bilateral cystic lung lesions. Parenchyma-sparing resections were performed. Histology revealed the presence of neuroglial cell-lined cysts and glial nodules. In addition, a neural element containing palatinal teratoma was detected and excised. Based on previously published cases, the pathogenesis and clinical features of pulmonary neuroglial heterotopia are discussed.

Abstract
Neural maturation involves diverse interaction and signaling mechanisms that are essential to the development of the nervous system. However, little is known about the development of neurons in heterotopic brain tissue in the lung, a rare abnormality observed in malformed babies and fetuses. The aim of this study was to identify the neurons and to investigate their maturation in experimental brain tissue heterotopia during fetal and neonatal periods. The fetuses from 24 pregnant female Swiss mice were used to induce brain tissue heterotopia on the 15th gestational day. Briefly, the brain of one fetus of each dam was extracted, disaggregated, and injected into the right hemithorax of siblings. Six of these fetuses with pulmonary brain tissue implantation were collected on the 18th gestational day (group E18), and six others were collected on the 8th postnatal day (group P8). The brain of each fetus from dams not submitted to any experimental procedure was collected on the 18th gestational day (group CE18) and on the 8th postnatal day (group CP8) to serve as a control for neuronal quantitation and maturation. Immunohistochemical staining of NeuN was used to assess neuron quantity and maturation. The NeuN labeling index was greater in the postnatal period than in the fetal period for the experimental and control groups (P8 > E18 and CP8 > CE18), although there were fewer neurons in experimental than in control groups (P8 < CP8 and E18 < CE18) (P < 0.005). These results indicate that fetal neuroblasts/neurons not only survive a dramatic event such as mechanical disaggregation, in the same way as it happens in human cases, but also they retain their development in heterotopia, irrespective of local tissue influences.

Abstract
The presence of heterotopic brain tissue in the lung is a rare abnormality. The cases reported thus far are usually associated with neural tube defects (NTD). As there are no reports of experimental models of NTD that present this abnormality, the objective of the present study was to develop a surgical method of brain tissue heterotopia in the lung. We used 24 pregnant Swiss mice divided into two groups of 12 animals each, denoted 17GD and 18GD according to the gestational day (GD) when caesarean section was performed to collect the fetuses. Surgery was performed on the 15th GD, one fetus was removed by hysterectomy and its brain tissue was cut into small fragments and implanted in the lung of its litter mates. Thirty-four live fetuses were obtained from the 17GD group. Of these, eight (23.5%) were used as control (C), eight (23.5%) were sham operated (S) and 18 (52.9%) were used for pulmonary brain tissue implantation (PBI). Thirty live fetuses were obtained from the females of the 18GD group. Of these, eight (26.6%) were C, eight (26.6%) S and 14 (46.6%) were used for PBI. Histological examination of the fetal trunks showed implantation of GFAP-positive brain tissue in 85% of the fetuses of the 17GD group and in 100% of those of the 18GD group, with no significant difference between groups for any of the parameters analysed. The experimental model proved to be efficient and of relatively simple execution, showing complete integration of the brain tissue with pulmonary and pleural tissue and thus representing a model that will permit the study of different aspects of cell implantation and interaction.
