Abstract
Situs inversus totalis (SIT) is a rare congenital anatomical variation. However, patients with SIT combined with cancer are rare and these patients with two types of lung cancer have not been reported. We report here a case of combined lung adenocarcinoma and solitary fibrous tumor of the pleura with SIT and discuss its clinicopathological features and outcomes. A 68-year-old asymptomatic woman was referred to the Affiliated Hospital of Qingdao University because of an abnormal shadow on chest radiography. Computed tomography showed SIT and an irregularly shaped nodule (measuring 38 × 27 mm in diameter) in the pleural area of the left lower lobe and a 5-mm nodule in the dorsal segment of the lower lobe of the left lung. Surgery was then performed. For such patients, we should eliminate anxiety in patients, perform regular reexaminations, focus on the individual features of these patients, and avoid misdiagnosis because of habitual thinking. At the same time, the lymph nodes should be completely removed and different parts of the tumor with different properties should be treated differently according to the situation.

Abstract
BACKGROUND Situs inversus (SI) is a rare congenital anomaly characterized by the transposition of thoracic and abdominal viscera. Laparoscopic pancreaticoduodenectomy (LPD) is increasingly used in patients with periampullar and pancreatic carcinomas. For patients with SI, LPD can be more complicated because of reversed anatomy and possible other associated anomalies that have not been expected before surgery. CASE PRESENTATION A female patient with SI totalis presented with inappetence, vomiting, and weight loss for 2 months. Imaging modalities and angiography revealed a mass in the periampullary region without obvious vascular abnormalities. The mass was successfully resected via LPD based on an elaborate preoperative plan. The surgical pathology report demonstrated adenocarcinoma of the duodenal papilla. The patient has been followed up for 4 months and no tumor recurrence or long-term complications were observed. CONCLUSION LPD is technically difficult but feasible in patients with SI.

Abstract
Situs inversus totalis (SIT) denotes complete right-left inversion of the thoracic and abdominal viscera. Diagnosis and surgical procedures for abdominal pathology in patients with SIT are technically more complicated because of mirror-image transposition of the visceral organs. Moreover, SIT is commonly associated with cardiovascular and hepatobiliary malformations, which make hepatobiliary-pancreatic surgery difficult. Two cases of pancreaticoduodenectomy for biliary tract carcinoma in patients with SIT are presented. Both patients had an anomaly of the hepatic artery. Advanced diagnostic imaging techniques were very important for careful preoperative planning and to prevent misunderstanding of the arrangement of the abdominal viscera. This facilitated the surgical team’s adaptation to the mirror image of the standard procedure and helped avoid intraoperative complications due to cardiovascular and hepatobiliary malformations associated with SIT. Pancreaticoduodenectomy in patients with SIT can be performed successfully with detailed preoperative assessment, use of effective techniques by the surgeon, and appropriate support by assistants.

Abstract
BACKGROUND Situs inversus totalis represents an unusual anomaly characterized by a mirror-image transposition of the abdominal and thoracic viscera. It often occurs concomitantly with other disorders that make difficult diagnosis and management of abdominal pathology. The relationship between situs inversus totalis and cancer remains unclear. CASE PRESENTATION We describe a 33-year old Guinean man with situs inversus totalis who presented with obstructive jaundice. Imaging and endoscopic modalities demonstrated a mass of distal common bile duct which biopsy identified an adenocarcinoma. The patient was successfully treated by cephalic pancreaticoduodenectomy followed by adjuvant chemoradiation and he is doing well without recurrence 8 months after surgery. CONCLUSION The occurrence of bile duct adenocarcinoma in patient with situs inversus totalis accounts as a rare coincidence. In this setting, when the tumor is resectable, surgical management should be considered without contraindication and must be preceded by a careful preoperative staging.

Abstract
Alterations of human laterality range from situs reversal or consensus isometry to isolated anomalies of the cardiac, respiratory, gastrointestinal, skeletal, and central nervous systems. A mechanism for human situs determination has been derived from the general model of Brown and Wolpert (1990) , with steps involving A-P axis, D-V axis, midline, global situs, and local situs specification. Comparison with Drosophila segmentation is supported by maternal transmission of certain human situs defects and mutation of appropriate Drosophila gene homologues in the human Waardenburg and Greig syndromes. Anteroposterior gradients in expression of vertebrate homeotic genes may relate to a proposed hierarchy of regional laterality decisions. Early alterations in A-P or D-V axis polarity would produce situs reversal in 100 of individuals, as observed in pure situs inversus, homozygous inv mice or manipulated Xenopus embryos. Later alterations would permit random right-left decisions and account for heterotaxy in 50 of affected individuals, as observed in poly asplenia or homozygous iv mice. Randomisation of brain asymmetry could explain why situs but not brain laterality may be reversed in humans, with forebrain situs reversal or isometry leading to brain anomalies. Homologues of Drosophila genes regulating axis polarity, heart and gut development are attractive candidates in human laterality disorders, but none is uniquely localised to the 6q14-q21 or9q32-q34, 7q22, 10q21-22, 11q13 or 11q25, 12q13, 13qter, or Xq24-q27.1 chromosome regions highlighted by heterotaxic patients or mutant mice.

Abstract
Discrepancies in upper and lower limb patterning in split hand foot malformation. Split hand foot malformation (SHFM) is genetically heterogeneous with five loci mapped to date. Highly variable in presentation, it can occur as an isolated finding or with other anomalies. The genetic heterogeneity and clinical variability make genetic counselling of SHFM families challenging. By establishing genotype/phenotype correlations, one can provide insight into responsible developmental genes and help to direct mapping efforts and target genetic testing, ultimately providing more accurate information for family members. Preaxial involvement of the upper extremities was a significant discriminating limb-specific variable in our analysis of genetically mapped SHFM cases. This finding, which was originally identified through descriptive epidemiology, was subsequently confirmed by discriminant function analysis (p < 0.0001) to be a significant locus discriminator. Preaxial involvement of the upper extremities was most commonly seen at the SHFM3 locus mapped to chromosome 10q24 (OMIM 600095) and consisted of proximally placed thumbs and/or triphalangeal thumbs (TPT), preaxial polydactyly and/or absence of the first ray. These patients' feet, however, tended to show a classical central longitudinal deficiency without a significant preaxial component. This article discusses this discrepant clefting pattern between the upper and lower extremities and proposes potential mechanisms.

Abstract
Heterotaxy results from failure of the developing embryo to establish normal left-right asymmetry. Typical manifestations include abnormal symmetry and malposition of the thoraco-abdominal organs and vessels, complex congenital heart disease and extracardiac defects involving midline-associated structures. The spleen is almost always affected, and there is syndromic clustering of the malformations corresponding to the type of splenic abnormality present. This review outlines the embryologic and genetic background of the heterotaxy syndrome as well as the characteristic anatomic features, clinical manifestations, and diagnostic clues of its two main presentations with asplenia or polysplenia.

Abstract
Many internal organs in the vertebrate body are asymmetrically oriented along the left-right (L-R) body axis. Organ asymmetry and some components of the molecular signaling pathways that direct L-R development are highly conserved among vertebrate species. Although individuals with full reversal of organ L-R asymmetry (situs inversus totalis) are healthy, significant morbidity and mortality is associated with perturbations in laterality that result in discordant orientation of organ systems and complex congenital heart defects. In humans and other vertebrates, genetic alterations of L-R signaling pathways can result in a wide spectrum of laterality defects. In this review we categorize laterality defects in humans, mice, and zebrafish into specific classes based on altered patterns of asymmetric gene expression, organ situs defects, and midline phenotypes. We suggest that this classification system provides a conceptual framework to help consolidate the disparate laterality phenotypes reported in humans and vertebrate model organisms, thereby refining our understanding of the genetics of L-R development. This approach helps suggest candidate genes and genetic pathways that might be perturbed in human laterality disorders and improves diagnostic criteria.

Abstract
We report on a female infant with partial deletion of the short arm of chromosome 18 (del 18p) and heterotaxy with left atrial isomerism. Congenital heart defect (CHD) is found in 10% of the literature reports. Interestingly, situs abnormalities have been diagnosed in four patients with del 18p, including ours. This finding could imply that a locus or loci involved in the development of normal body situs lies within this chromosomal region. Del 18p must be consid- ered when evaluating a patient with phenotypic anomalies and CHD in lateralization defects.

Abstract
PURPOSE To provide insight into the possible etiology and prevalence of heterotaxy, we studied conditions associated with heterotaxy in a consecutive hospital population of newborns. METHODS From 1972 to March, 1999 (except February 16, 1972 to December 31, 1978), 58 cases of heterotaxy were ascertained from a cohort of 201,084 births in the ongoing Active Malformation Surveillance Program at the Brigham and Women's Hospital. This registry includes livebirths, stillbirths, and elective abortions. Prevalence among nontransfers (i.e., patients whose mothers had planned delivery at this hospital) was calculated as approximately 1 per 10,000 total births (20 of 201,084). RESULTS We analyzed a total of 58 patients consisting of 20 (34%) nontransfers and 38 (66%) transfers. Patients were categorized by spleen status as having asplenia (7 nontransfers, 25 total), polysplenia (8, 20), right spleen (4, 11), normal left (0, 1), and unknown (1, 0). Among the 20 nontransfer and 59 total heterotaxy patients, the following associated medical conditions were present: chromosome abnormality (1 nontransfer, 2 total), suspected Mendelian or chromosome microdeletion disorder (1 nontransfer, 6 total), and maternal insulin-dependent diabetes mellitus (1 nontransfer, 2 total). There were 6 twins (1 member each from 6 twin pairs including 1 dizygous, 4 monozygous, 1 conjoined; 2 were nontransfers). An associated condition occurred in 5 (25%) nontransfer and 16 (28%) total patients, or among 10 of 53 singleton births (19%). CONCLUSIONS Although most cases of heterotaxy in this series were sporadic events, an associated condition was present in about one-fourth of the cases. Not all of these conditions would be considered causative etiologies. Based on this small series alone, maternal insulin-dependent diabetes cannot be viewed as a risk factor for heterotaxy. However, the specific association of diabetes with polysplenia with/without left atrial isomerism is noteworthy, and adds weight to animal and epidemiologic case-control data.

Abstract
We report on two cases of microdeletion of chromosome sub-band 2q37.3 with abnormal situs viscerum. The first patient had dextrocardia, duodenal and jejunal atresia, and an abdominal hernia. The liver was in the left upper quadrant, stomach in the right upper quadrant. In contrast anema the ascending colon was in the left, and descending colon on the right, with an area of atresia in the mid-jejunum. The second patient had malrotation and malposition of large and small bowel, with most of the bowels positioned above the liver and spleen. There was incomplete rotation of the cecum. The right kidney was malrotated and mal-positioned. The finding of 2q37.3 deletion in both patients implies that a locus or loci involved in the development of normal body situs lies within this chromosome region. Molecular cytogenetic evaluation for a possible 2q37.3 deletion should be considered in patients with abnormal situs viscerum.

Abstract
We report a family in which the proband has a direct insertion of band 7q21.3 into chromosome 22 at 22q13.3, karyotype 46,XX,dir ins(22;7)(q13.3;q21.2q22.1). Two of her children have unbalanced chromosome rearrangements involving 7q21.3, with one girl monosomic for the region and a boy trisomic for the region. The child monosomic for band 7q21.3 has a split hand/split foot (SHSF) anomaly and her clinical features are consistent with the 7q21-q22 contiguous gene deletion syndrome. In situ hybridisation studies have shown that the proband and her son have a submicroscopic deletion of chromosome band 22q13.3. Interstitial deletions of this chromosome band have rarely been reported.

Abstract
Split hand/split foot malformation (SHSF) has been described in several patients associated with cytogenetically visible rearrangements involving chromosome 7q. Characterisation of these patients has led to localisation of an autosomal dominant form of SHSF to 7q21-22; the locus has been designated SHFM1. We describe a patient with a complex, apparently balanced cytogenetic rearrangement, including a translocation breakpoint at 7q21.3 near the DSS1 gene. In addition to ectrodactyly of all four limbs, the patient has congenital deafness, submucous cleft palate, microcephaly, and mental retardation. This patient represents an additional case of syndromic ectrodactyly related to the SHFM1 gene region, which may be responsible for both syndromic and non-syndromic ectrodactyly.

Abstract
We present a 6-year-old girl with a balanced 11;20 translocation [46,XX,t(11;20)(q13.1;q13.13)pat], asplenia, pulmonic stenosis, Hirschsprung disease, minor anomalies, and mental retardation. This case represents the second report of an individual with situs abnormalities and a balanced chromosome rearrangement involving a breakpoint at 11q13. Polymerase chain reaction (PCR) analysis of microsatellite markers excluded uniparental disomy for chromosomes 11 and 20. Segregation analysis of markers in the 11q13 region in the proposita and her phenotypically normal carrier sibs did not show a unique combination of maternal and paternal alleles in the patient. We discuss several possible explanations for the simultaneous occurrence of situs abnormalities and a balanced 11;20 translocation. These include (1) chance, (2) a further chromosome rearrangement in the patient, (3) gene disruption and random situs determination, and (4) gene disruption plus transmission of a recessive or imprinted allele from the mother.

Abstract
Heterotaxy results from failure to establish normal left-right asymmetry during embryonic development. Most familial cases are thought to be autosomal recessive. We have identified a family in which 4 individuals from 3 generations manifest laterality defects. Twenty-five family members have been examined. Two have complete reversal of normal laterality (situs inversus) while 2 others have asplenia, midline liver, and complex cardiac malformations (situs ambiguus). Two additional obligate gene carriers are anatomically normal (situs solitus). Male-to-male transmission confirms autosomal inheritance. Identification of this family establishes an autosomal dominant form of laterality defect, suggesting that a portion of sporadic cases may be new-mutation dominant or unrecognized familial cases. The finding of all forms of laterality (solitus, ambiguus, and inversus) among obligate disease gene carriers within a single family may be relevant to genetic evaluation and counseling in apparently isolated patients with laterality disturbance.

Abstract
A boy with typical tetramelic split hands and feet is described. In addition, there was a large arteriovenous malformation of the right arm. Chromosome studies showed a pericentric inversion of chromosome 7: 46,XY,inv(7)(p22q21.3). Inspection of the extremities and chromosome studies in the parents were normal. This case confirms the suggested localisation of a locus, important for early limb differentiation, on the long arm of chromosome 7, most probably in the chromosomal region 7q21.2-7q21.3. Previously reported cases are reviewed briefly.

Abstract
We report on an individual with severe mental retardation, seizures, microcephaly, unusual face, scoliosis, and cleft feet and cleft right hand. The chromosomal study showed a proximal interstitial deletion 7q (q11.23q22). From our review of the literature, 11 patients have been reported with ectrodactyly (split hand/split foot malformation) and proximal/intermediate interstitial deletions or rearrangements of 7q. The critical segment for ectrodactyly seems to be located between 7q21.2 and 7q22.1. This malformation is present in 41% of the patients whose deletion involves the critical segment.
