1/158. Epignathus, double pituitary and agenesis of corpus callosum.Two infants from unrelated families died on the 1st day of life with epignathus, duplication of the entire pituitary, infundibulum and sella, and widening or separation of midline structures of the head including absent corpus callosum. We suggest that some infants surviving surgery for large epignathi may have relatively symptomless absent corpus callosum or double pituitary.- - - - - - - - - - ranking = 1keywords = pituitary (Clic here for more details about this article) |
2/158. Diprosopus (partially duplicated head) associated with anencephaly: a case report.Craniofacial duplication (diprosopus) is a rare form of conjoined twin. A 16 year old mother with a twin pregnancy delivered one normally formed baby boy and one diprosopus male. The malformed baby was 33 weeks of gestation with a single trunk, normal limbs and various degrees of facial duplication. Of the following structures there were two of each: noses, eyes, ears (and one dimple), mouths, tongues and, with bilateral central cleft lips and cleft palates. This was associated with holoprosencephaly and craniorachischisis. Internal organs showed no duplication. There were multiple congenital anomalies including diaphragmatic hernia, small lungs, two lobes of the right lung, ventricular septal defect, small adrenal gland and small left kidney with short ureter. The body also had a short neck, small chest cavities and kyphosis. X-ray revealed duplication of the vertebral column. The case presented here represents a type II of diprosopia of Rating (1933) and is the least common type reported. We also reviewed 22 recently reported cases of diprosopus. In addition to facial duplication, anencephaly, neural tube defect and cardiac malformations represent the more common congenital abnormalities associated with diprosopus. The pathogenesis of diprosopus is not well understood. Factors that play a role in diprosopus are probably similar to those factors (genetic, environmental and abnormal placental circulation) which affect monozoygotic twins as observed in this case report. Early ultrasonography diagnosis of diprosopus permits one to consider a vaginal therapeutic abortion.- - - - - - - - - - ranking = 0.012785278300472keywords = gland (Clic here for more details about this article) |
3/158. A Rapp-Hodgkin like syndrome in three sibs: clinical, dental and dermatoglyphic study.Rapp-Hodgkin ectodermal dysplasia is an autosomal dominant disorder characterized by distinctive craniofacies, cleft lip or palate, oligodontia or anodontia, hypoplasia of the nails, and a decrease in or absence of the sweat glands and hair follicles. We have identified a family in which three children display clinical features similar to Rapp-Hodgkin syndrome. The father and two other sisters of the patient had normal facial features, but had short stature and had dental anomalies, the latter suggestive of ectodermal dysplasia. The overall clinical, dental, and dermatoglyphic findings of these patients are discussed in relation to reports of families with Rapp-Hodgkin syndrome.- - - - - - - - - - ranking = 0.012785278300472keywords = gland (Clic here for more details about this article) |
4/158. Aplasia of right internal carotid artery and hypopituitarism.BACKGROUND: The pathogenesis of congenital hypopituitarism is unknown in many cases. OBJECTIVE: We report a case of congenital pan-anterior hypopituitarism in association with a complex vascular abnormality involving the central nervous system, nasal pyriform aperture stenosis, and a single central maxillary incisor. MATERIALS AND methods: MRI and MRA were used to define this patient's complex vascular anomaly. RESULTS: The vascular abnormality consists of absence of the right common carotid artery, the right internal carotid artery, the A1 segment of the right anterior cerebral artery, the anterior communicating artery, and partial absence of the M1 segment of the right middle cerebral artery. CONCLUSION: This unusual vascular anomaly may contribute to the pathogenesis of some cases of congenital hypopituitarism and related midline abnormalities, or may result from a common defect that causes pituitary insufficiency.- - - - - - - - - - ranking = 0.16666666666667keywords = pituitary (Clic here for more details about this article) |
5/158. Epignathus teratoma: report of three cases with a review of the literature.Three cases of epignathus teratoma associated with other midline anomalies are reported. The first case involved Pierre Robin sequence and a bifid tongue. The second case was characterized by two teratomas, a meningoencephalocele, and a cleft lip and nose. The third case had Pierre Robin sequence associated with duplication of the pituitary gland and hypoplasia of the corpus callosum.- - - - - - - - - - ranking = 0.95244132401075keywords = pituitary gland, pituitary, gland (Clic here for more details about this article) |
6/158. Heterotopic thyroid tissue at the porta hepatis in a fetus with trisomy 18.Heterotopic thyroid tissue at the porta hepatis in a fetus with trisomy 18 is described. The fetus had an eutopic thyroid gland without any abnormalities. The heterotopic thyroid was found at the porta hepatis and showed histological features similar to the eutopic thyroid. Immunohistochemically, the heterotopic follicles were positive for thyroglobulin, but no calcitonin-positive cells were found. Intra-abdominal heterotopic thyroid is exceedingly rare in locations other than the ovary, and to our knowledge, this is the first report of a fetal case. The present case provides clear evidence that abdominal heterotopic thyroid can occur as a congenital anomaly. Migration abnormality of the median anlage of the thyroid is the most likely histogenesis of heterotopic thyroid at the porta hepatis.- - - - - - - - - - ranking = 0.012785278300472keywords = gland (Clic here for more details about this article) |
7/158. Congenital nasal pyriform aperture stenosis associated with central diabetes insipidus.We describe a child who has central diabetes insipidus associated with congenital nasal pyriform aperture stenosis without any apparent anterior pituitary dysfunction. This association further strengthens the concept that congenital nasal pyriform aperture stenosis may be a microform of holoprosencephaly.- - - - - - - - - - ranking = 0.16666666666667keywords = pituitary (Clic here for more details about this article) |
8/158. A patient with de Morsier and Duane syndromes.de Morsier syndrome, or septo-optic dysplasia, is a developmental malformation complex characterized by optic nerve hypoplasia, dysgenesis of the septum pellucidum, and hypothalamic-pituitary dysfunction. (1,2) In duane retraction syndrome, there is absence of the sixth nerve nucleus with congenital retraction of the globe and narrowing of the lid fissure in adduction, frequent abduction deficiency, and variable limitation to adduction of the affected eye. (3) The purpose of this report is to present a patient with the uncommon and previously unreported concurrence of both of these congenital malformation complexes, presumably because of a common disturbance of neuronal development.- - - - - - - - - - ranking = 0.16666666666667keywords = pituitary (Clic here for more details about this article) |
9/158. costello syndrome: a cancer predisposing syndrome?costello syndrome is a specific MCA/MR syndrome mainly characterized by dysmorphic facial features, peculiar biphasic growth pattern, motor and mental retardation, ectodermal anomalies involving skin and nails, and age dependent development of nasal and perianal papillomata. heart malformations and/or hypertrophic cardiomyopathy are frequently observed. We report a 4-year-old girl with costello syndrome who developed an intrathoracic ganglioneuroblastoma. In previous reports two patients with ectodermal tumours have been described, a ganglioneuroblastoma of the adrenal gland and an epithelioma. This third report suggests that neural crest neoplasia may be a significant risk factor for children with costello syndrome.- - - - - - - - - - ranking = 0.012785278300472keywords = gland (Clic here for more details about this article) |
10/158. Case of complex craniofacial anomalies, bilateral nasal proboscides, palatal pituitary, upper limbs reduction, and amnion rupture sequence: disorganization phenotype?We report a case of a dizygotic twin with complex abnormalities of head, body, and limbs. The anomalies include the following: lateral and midline cleft upper lip, ectopic palatal pituitary, natal teeth, bilateral nasal proboscides with an absent nose, left microphthalmia with conjunctival-lined cyst, right ocular dysgenesis, bilateral retinal dysplasia, platybasia with skull asymmetry, hydrocephalus secondary to aqueductal atresia, brain hemispheric asymmetry with a parietal-occipital cortical flap, agenesis of posterior corpus callosum, absence of the olfactory nerves and left anterior cerebral artery, leptomeningeal and intraventricular heterotopias, right radial longitudinal terminal meromelia with constriction rings of fingers, partial syndactyly of the third and fourth left fingers, dorsiflexed great toes and pes equinovarus bilaterally, and multiple skin tags with a sacral appendage. Additionally, this twin's placental disc and extraplacental membranes were devoid of amnion. We regard these anomalies as a possible expression of the human homologue of the disorganization phenotype or another gene mutation. Nevertheless, an abnormality of blastogenesis with early damage to organizing tissues of the frontonasal region and limbs, or a vascular disruption, cannot be excluded. Early amnion rupture sequence (possible extraamniotic pregnancy with amniotic bands, limb reduction defects with Streeter bands, and multiple skin tags tapering into amniotic bands) was also present in this case, and may have acted as a contributing factor.- - - - - - - - - - ranking = 0.83333333333333keywords = pituitary (Clic here for more details about this article) |
