Various types of fibromatosis have been reported in infancy and early childhood. We describe an infant with diffuse fibromatosis on the scalp. A one year and five months-old girl showed a diffuse and hard mass 3 × 5 cm in diameter and no tenderness on the scalp. Two months later, the size of the mass had increased and several other tumors appeared on the lateral head. The magnetic resonance imaging (MRI) disclosed that a large and diffuse tumor had spread from the frontal to occipital head; a ‘helmet-like’ configuration of the tumor was exhibited on sagittal MR images. The tumor showed high signal intensity on T2-weighted images and was enhanced with Gd-DTPA. Histological examination showed a fibroblastic proliferation with intervening thick collagen bundles. The patient was diagnosed as having diffuse fibromatosis. The tumor at the resection site immediately recurred, whereas the tumor in the frontal head showed marked regression. Three months after the resection, new tumors appeared in the occipital head. The size and number of these tumors have remained unchanged for more than 18 months. The sites and appearance of the tumors were identical to that of juvenile hyaline fibromatosis (JHF) in this patient. However, JHF usually includes fibroblasts associated with large amounts of hyalinized collagen-like material, which were not present in our patient. The different histology of JHF comparing our case and other reported cases may depend on the different phase of the disease progression at resection. Long-term observation is necessary for the appropriate diagnosis and evaluation of prognosis in this patient. 相似文献

This is the report on a prospective, single blind, comparative study of a component acellular pertussis vaccine produced by a combination of detoxified, column purified pertussis toxin (PT) and filamentous hemagglutinin (FHA) combined with diphtheria and tetanus toxoids (DTcaP) and the traditional acellular pertussis vaccine produced with essentially the same method as described by Sato with DT (DTaP) of the same manufacturer. A total of 616 infants and children received DTcaP and a total of 289 received DTaP. In all age groups for both vaccines values of serum antibodies to PT and FHA after two doses of the vaccines were comparable to those of convalescent sera. Incidences of systemic and local reactions were, in general, not greatly different between DTcaP and DTaP recipients. In Japan the use of traditional acellular vaccines replaced whole cell vaccines in 1981. Protective antigens of Bordetella pertussis have now been specified and thus component vaccines have become theoretically possible. This is the first component vaccine which has been developed in Japan. Several other component vaccines are now under investigation in the world. 相似文献

We describe two cases of asymptomatic Brugada syndrome that displayed a persistent ECG manifestation, but in which the typical ECG pattern disappeared following surgical castration for prostate cancer. These facts suggest a possible association between manifestation of the Brugada-type ECG pattern and testosterone. (PACE 2003; 26[Pt. I]:1551–1553) 相似文献

Aims : We rarely encounter solid-type poorly differentiated colorectal carcinoma, and their histogenesis and biological behaviour are not fully disclosed. Methods and results : A review of 60 poorly differentiated carcinomas of the colorectum was undertaken, 36 (59%) of which were located in the right side of the colorectum. Although, on the basis of the World Health Organization (WHO) classification solid carcinomas are included among undifferentiated carcinomas, the poorly differentiated carcinomas were divided into four types; 27 solid carcinomas (Sol.), 17 poorly differentiated adenocarcinomas (PDA), six signet-ring cell carcinomas (Sig.) and 10 mucinous carcinomas (Muc.). Solid carcinomas revealed a solid alveolar growth of fairly uniformly sized tumour cells with occasional mitotic figures. This type of tumour had a relatively lower percentage of lymphatic permeation and lymph node metastasis compared with the other three types. The 5-year survival rates were 31% for all poorly differentiated carcinomas, 47% for the Sol. type, 32% for the PDA type, and 0% for both the Sig. and the Muc. types, with a rate of 72% for well-differentiated adenocarcinomas selected as controls. Immunohistochemically, bcl-2 protein expression was demonstrated in 38% of the Sol. type, but in only 12 % of the other three non-solid types, this difference being significant ( P < 0.05). Conclusions : These findings suggest that solid carcinomas of the colorectum should be regarded as a distinct type of poorly differentiated carcinoma, leading to a good prognosis. 相似文献

To assess the characteristics of intrahepatic metastatic lesions (IML) in hepatocellular carcinoma (HCC), we analysed both the histological features and proliferative activities of 15 resected cases of HCC accompanied by IML. The histological features of the IML were essentially the same as those observed in the main nodules in 12 (80%) of 15 cases. In 13 (87%) of 15 cases, the labelling index of proliferating cell nuclear antigen (PCNA) in the IML was either higher than or the same as in the main nodules. In 10 (77%) of 13 cases, the MIB-1 labelling index in the IML was either higher than or the same as in the main nodules. The results indicate that the histological features of the IML are essentially the same as those of the main nodules, while the proliferative activities in the IML were generally higher than those in the main nodules. Such characteristics may thus provide a clue to help distinguish intrahepatic metastasis from the multicentric occurrence of HCC. 相似文献

A 2-year-old boy developed acute myositis associated with rotavirus gastroenteritis. He had remarkable swelling and subcutaneous edema, mostly in the legs, 4 days after the onset of gastroenteritis. Marked elevation of creatine kinase was observed while serum albumin, immunoglobulin, and complement were decreased. 相似文献

Sarcomatous transformation is found in approximately 5% of patients with intrahepatic cholangiocarcinoma. According to previous reports, sarcomatous cholangiocarcinomas are composed of spindle-shaped cells and/or multinucleated giant cells. Usually, vimentin is expressed by these sarcomatoid cells. We report a case of intrahepatic cholangiocarcinoma with an element of rhabdoid cells that occurred in a 61-year-old woman admitted for back pain. Various imaging techniques demonstrated multiple liver masses. Histologically, these tumours formed in both sarcomatous and ordinary tubular adenocarcinomatous areas. The sarcomatoid areas were occupied mainly by loosely arranged, eosinophilic rhabdoid cells, which expressed both keratin and vimentin. These findings suggest that rhabdoid cells may occur in an undifferentiated stage of cholangiocarcinoma and possess a strong tendency to metastasize. 相似文献

Recently, the expression of vimentin has been reported in some carcinomas. This study was designed to clarify the significance of vimentin expression in solid type poorly differentiated adenocarcinomas of the stomach. Immunohistochemically, 239 poorly differentiated adenocarcinomas with solid components of the stomach were stained for vimentin. Vimentin-positive cases were also stained by CAM 5.2 using serial mirror sections. We found 15 (6.3%) vimentin-positive cases. Twelve of them demonstrated varying amounts of rhabdoid-like cells. Eight cases diffusely co-expressed vimentin and cytokeratin simultaneously. In addition, four co-expressing cases showed positive staining with Keratin-903 which recognizes the high molecular-weight cytokeratin. Most of the co-expressing cases showed a diffuse proliferation of polygonal tumour cells with focal cell-to-cell contact. The prognosis of the co-expressing cases was poor in comparison with that of the 89 vimentin-negative tumours ( P < 0.05). 相似文献

A 30 year old female was admitted twice during her pregnancy for genital bleeding. An ultrasonography at 19 weeks gestation showed several nodules on the chorionic plate. Cardiotocography during labor at 37 weeks gestation indicated a non-reactive pattern. A 2230 g infant girl was delivered soon after rupture of membranes with asphyxia and hydrops fetalis. The placenta weighed 600 g with a maximal thickness of 6 cm. Nodules occupied about one-third of the placenta and were diagnosed as placental hemangiomas. Postnatal examination revealed that the infant had disseminated intravascular coagulation and cardiac failure. This baby recovered after treatment in the intensive care unit, and was discharged home on the 52nd day of life. 相似文献
