Pelvis-shoulder dysplasia is rare skeletal dysplasia characterised by symmetrical hypoplasia of the iliac wings and scapulae. It may be associated with unstable hips in infancy, a prominent lumbar lordosis and a waddling gait. Symptoms tend to lessen with increasing age. A child with this condition who has been followed up to the age of five years is described. Her pelvic dysplasia is milder than in previous cases and has caused no disability. Minor skeletal abnormalities are also present in the lumbar spine, femora and rib cage. Radiography of other members of the family was normal.

The extracellular matrix adhesion molecule fibronectin exhibits different isoforms derived by alternative splicing as well as recently demonstrated variation in O-glycosylation. Although fibronectin is widely distributed in normal tissues, the individual isoforms have been found to show restricted tissue distribution and association with malignancies. The monoclonal antibody FDC-6 defines a cancer-associated de novo glycosylation of a specific threonine residue in the C-terminal region of the fibronectin molecule termed oncofetal fibronectin. Here we report an immunohistological study of oral squamous cell carcinomas (n = 33), premalignant lesions (n = 15), and normal oral mucosa (n = 10) using the FDC-6 antibody. A selective expression of the oncofetal fibronectin epitope was demonstrated in close relation to the invading carcinoma, whereas no staining was observed in premalignant lesions without epithelial dysplasia, or in normal epithelium. Furthermore, we attempted to identify additional carbohydrate-related epitopes distinguishing fibronectin of human hepatoma cell line HUH-7 from plasma fibronectin. No novel epitopes were identified, as all generated monoclonal antibodies lacking reactivity with plasma fibronectin showed the same specificity as FDC-6. Previous studies have indicated that the de novo glycosylation is induced by a novel transferase activity only found in fetal and carcinoma cell lines, placenta and hepatoma tissues. Here we provide further evidence that a purified UDP-GalNAc:peptide N-acetylgalactosaminyltransferase from normal bovine thymus and human placentae is incapable of utilizing the hexapeptide VTHPGY as a substrate. The results demonstrate that oncofetal fibronectin is highly associated with malignancy, and appears to be induced by expression of a unique glycosyltransferase or modification of the specificity of the normally expressed transferase.

The campomelic syndrome is a skeletal dysplasia with a characteristic pattern of deformity involving the proximal and distal extremities, pelvic and shoulder girdles, thoracic cage and palate. Respiratory compromise often leads to death in early infancy. Etiology has not been determined although evidence suggests genetic heterogeneity in patients with campomelia. Cytogenetic analysis in the past have revealed an unexpectedly high incidence of a 46, XY karyotype in phenotypic females. We report here on a patient with a typical case of campomelic dysplasia in whom a de novo paracentric inversion of chromosome 17q was identified. Review of the genetic map of the inverted region identified potential "structural" genes including the Hox-2-homeobox gene and the collagen gene, COLIA1, which may be involved in the pathogenesis of campomelic syndrome.

We examined the localization of squamous cell cancer associated antigens (SCCAA) in dysplasia, cancer in situ (CIS) and microinvasive SCC of the uterine cervix, since detection of SCCAA in these subjects is highly effective for early diagnosis. Anti-squamous cell cancer associated antibody (Anti SCCAAb IgG) was prepared by immunizing rabbits with specific components at around PI 6.1 that were originally purified from SCC of maxillary sinus. In this study, the following results were obtained by the immunoperoxidase method. (1) Eleven out of 15(73%) cases of dysplasia, 20 out of 26(77%) cases of CIS, 21 out of 24(88%) cases of Stage I, 13 out of 14(93%) cases of Stage II and 9 out of 10(90%) cases of Stage III-IV in the clinical stages of SCC showed positive staining, while controls of unrelated SCC were almost negative. (2) The SCCAA positive ratio was 2 out of 2 cases of small cell nonkeratinized type, 86% in large cell nonkeratinized type and 94% in Keratinized type of SCC. (3) The SCCAA was demonstrated on all the layers of stratified squamous epithelium in a lesion of CIS and some layers migrated to adjacent nonneoplastic lesion with lateral invasion in middle layer. These results suggest that the demonstration of SCCAA may be useful in diagnosing the malignant transformation of squamous epithelium in the early stage of SCC.

Spondylocostal dysplasia (Jarcho-Levin syndrome) comprises multiple malformations of the vertebrae and ribs coupled with a characteristic clinical picture of short neck, scoliosis, short trunk, and deformity of the rib cage. We describe a patient with the syndrome who also had spina bifida and diastematomyelia. We surmise that this association is not coincidental. Additional evidence is needed to support the hypothesis that spondylocostal dysplasia and neural tube defects are aetiologically related.

Apert-Crouzon syndrome (formerly ACS type 2; 10130) is now considered a subset of autosomal dominant Apert acrocephalosyndactyly type 1 (10120), with features of craniosynostoisis, syndactyly of all extremities, maxillary hypoplasia, "parrot-beaked" nose, hypertelorism, exophthalmos, external strabismus, and short upper lip. We report a 3 1/2-month-old infant with features of Apert syndrome, plus thoracic vertebral anomalies radiographically similar to those seen in spondylothoracic dysplasia, a condition in which block thoracic vertebrae with widely open neural arches and a fan-shaped thoracic cage are found. Our patient also had flared metaphyseal ends of humeri, dislocated radii with immobile elbows, an unusual tail-like protuberance in the coccygeal area, and a solid cartilaginous tracheal wall. To date, in ongoing reviews of radiographs of other patients with acrocephalosyndactyly or acrocephalopolysyndactyly complexes and of relevant literature, we have not identified other patients with these findings. The vertebrae and intervertebral discs of the patient in this report, three patients with Jarcho-Levin syndrome, and one with Apert syndrome were measured from anteroposterior chest radiographs; the findings clearly distinguish the condition in our patient from Jarcho-Levin syndrome or Apert syndrome.

Human colorectal carcinoma tissues may exhibit several patterns of altered blood group substance (BGS) expression: reappearance of A, B, H, or Lewisb antigens in distal colon; deletion of BGS in the proximal colon with or without precursor substance accumulation; and incompatible BGS expression in proximal or distal colon. The present study evaluated these cancer-associated alterations in colorectal polyps with different malignant potential. With respect to ABH antigens, hyperplastic polyps (HPs), considered to have no malignant potential, did not exhibit incompatibility and only a few cases demonstrated BGS reappearance or deletion. Adenomatous polyps (APs) however, frequently reexpressed ABH antigens or expressed incompatible BG-A or B in 27% of polyps; one specimen demonstrated BG-B deletion. Precursor expression was not found in HPs but was frequently observed in APs. Reappearance of ABH in distal polyps was significantly correlated with increasing grade of dysplasia, but was not significantly correlated with polyp size or histological type. With respect to Lewis antigen expression, Lewisb reappearance occurred in almost every distal polyp, and Lewisa-Lewisb coexpression was also quite common. Lea deletion was frequently noted, especially in HP, but the significance of this finding is unclear. This study indicates that several antigenic alterations that occur in colorectal cancer tissues also appear in premalignant polyps, and often in early stages of the neoplastic process. The observation that incompatible expression of BG-A or B occurs only in AP and cancer tissues (as well as mucosa adjacent to cancer) but not in fetal colonic mucosa, adult normal colonic mucosa, or HP, suggests that this may be a cancer-specific phenomenon.

The LeY determinant, a difucosylated type 2 blood group-related antigen, is a positional isomer of the Leb blood group antigen and a fucosylated derivative of the LeX antigen. The LeX antigen behaves like an oncodevelopmental tumor-associated antigen in human colon cancer, and extended polyfucosyl LeX antigens are more specific for colon cancer tissues than are simple, monofucosyl LeX antigens. The present investigation compared the expression of simple and extended LeY antigens in a variety of malignant and nonmalignant human colonic tissues to gain insight into the normal distribution and cancer-associated expression of these antigens. Monoclonal antibody AH-6, which recognizes the LeY epitope irrespective of its carrier carbohydrate chain, stained the majority of specimens regardless of malignant potential or location within the colon. In contrast, CC-1 and CC-2 monoclonal antibodies, which recognize extended LeY structures, and KH-1, which is specific to trifucosyl LeY, preferentially stained malignant colonic tissues and rarely stained normal colonic mucosae. Mucosa immediately adjacent to cancer usually stained with AH-6 but not with KH-1, CC-1, or CC-2. Extended or trifucosyl LeY antigen expression was limited exclusively to premalignant (adenomatous) polyps and was invariably absent from nonpremalignant (hyperplastic) polyps. Moreover, among adenomatous polyps, extended LeY antigen expression tended to correlate with three parameters of malignant potential: larger polyp size; villous histology, and severe dysplasia. AH-6 failed to distinguish between hyperplastic and adenomatous polyps. In second-trimester fetal colonic mucosa, AH-6 bound to both proximal and distal segments whereas KH-1, CC-1, and CC-2 bound only to proximal segments. We conclude that in human colon, the LeY hapten is an oncodevelopmental cancer-associated antigen and extended LeY antigens are highly specific markers for malignancy and premalignancy.

A case of kyphomelic dysplasia is reported in a boy followed up over three years. The most striking feature of this recessively inherited generalised bone dysplasia is marked angulation of the femora, associated with short stature, bowing and shortening of other long bones, metaphyseal changes in infancy, flared ribs, small thoracic cage, and platyspondyly. The good prognosis regarding motor and intellectual development in this condition is stressed and the association with cleft lip and palate is described for the first time.

Substantial agreement has previously been demonstrated between qualitative and morphometric grading of gastric dysplasia. In the present study, a further attempt is made to quantitatively define the dysplastic changes in relation to associated benign or malignant changes of gastric mucosa. In total, 232 cases were studied and were associated with benign peptic ulcer (89 cases), histologically proven gastric cancer (88 cases), and gastritis-associated mild, moderate, and severe dysplasias (55 cases). The analysis showed that one discriminant function consisting of seven morphometric features is sufficient to separate the regenerative and cancer-associated cases. The classification results obtained on the basis of this discriminant function in both training and testing sets are encouragingly similar, indicating that the classification is reliable. This was further confirmed by the results of the application of this rule in the mild, moderate, and severe dysplasia biopsies (the above-mentioned gastritis-associated cases) used in a previous study. The quantitative analysis permits two grades, instead of three, to be distinguished: low-grade and high-grade dysplasia.
