In the present study, 13 cases of a peculiar gall-bladder granuloma characterized by marked proliferation of ceroid-fllled brown histiocytes were pathomorphologically, histochemically and ultrastructurally examined to define the pathologic features of such a lesion previously undescribed in the literature. The lesion grossly showed a granulomatous appearance of yellow brown to dark brown color developing in the wall of gall-bladder. Histologically, there was proliferation of histiocytes containing abundant brown pigment granules In their cytoplasm. The pigment granules proved to have staining characteristics closely resembling those of lipogenic ceroid-like pigment. Ultrastructurally, these granules showed membrane-bound, pleomorphic osmiophilic inclusions of heterogenous materials. With regard to the pathogenesis of this granuloma, it may be suggested that lipid components of bile juice, particularly unsaturated fatty acids and phospholipids, play an Important role as a source of ceroidogenesis In the proliferating histiocytes. 相似文献

A case of the syndrome of sea-blue histiocyte is presented in a 53-year-old Japanese woman, which is the first recorded case in Japan. The patient had hepatosplenomegaly, bleeding manifestations, mild thrombocytopenia, fatty metamorphosis and cirrhosis of the liver, as well as abnormal serum lipid profiles. Her parents were consanguineous and her maternal grandmother with hepatomegaly died of hepatic failure. Histologically, peculiar histiocytes containing numerous, intracytoplasmic sea-blue stained granules on May-Giemsa stain were demonstrated in biopsy materials of the bone marrow, lymph node and liver. The sea-blue granules in these histiocytes proved to have histochemical staining characteristics of lipogenic ceroid-like pigment. Ultrastructurally, these granules showed membrane-bound, pleomorphic inclusions of heterogeneous nature, including electron-dense amorphous or variegatedly osmiophilic, frequently laminated materials. Enzyme cyto-chemically, localization of acid phosphatase activity was demonstrated in and around the intracytoplasmic inclusions. With regard to the pathogenesis of the sea-blue histiocytes in this case, it may be suggested that the existence of the abnormality in lipid metabolism plays an imporant role in intralysosomal ceroidogenesis in these histiocytes. 相似文献

Immunohistochemical profile of primary sclerosing Iipogranuloma of the scrotum: Report of five cases
Kazuo Watanabe Nobuo Hoshi Kei-ichi Baba Takeaki Fukuda Hando Hakozaki Toshimitsu Suzuki 《Pathology international》1995,45(11):854-859
Five cases of primary sclerosing scrotal lipogranuloma were examined histologically and immunohistochemically. Every case lacked a history of injection or trauma, and revealed Common histologicat features; a typical granuloma composed of epithelioid cells and multinucleated giant cells, and inflammatory infiltrates of eosinophils, lymphocytes and macrophageimonocytes in the interstitium. lmmunahistochemistry disclosed the epithelioid cells and multinuclaated giant cells of the granuloma to be monocytetr in nature, as bath types of cells were positive for lyso-yme, α-1-antltrypin, α-1-antichymotrypsin, and KP-1. In the interstitium, KP-1 positive monocytes, L-26 positive B lymphocytes, UCHL-1 positive T lymphocytes and 5–100 protein positive Langerhans-like cells were frequently found. 5100 protein positive cells could not be detected in the granuloma. Primary sclerosing lipogranuloma of the scrotum, therefore, is a peculiar inflammation characterized by granulomas consisting of monocytes and marked tissue eosinophilia of unknown etiology. 相似文献

Demographic, drug use and criminal correlates of risky drug practices were examined among 279 detained youth in NSW Juvenile Justice Centres. Binge drinking was common, with 63% reporting the consumption of at least five drinks in a row in the 2 weeks prior to incarceration. It was associated with being older, being from an English-speaking background, regular tobacco consumption and having a current drug problem. A quarter (24%) of the sample had injected an illicit drug, over one-third (37%) of whom also reported sharing needles. Injectors were more likely to be polydrug users, regular amphetamine users and have a past history of drug treatment. While 16% of the sample indicated a need for drug treatment, only 10% were currently receiving some form of treatment, most commonly counselling. Appropriate strategies are needed among this population to address gaps in treatment provision. 相似文献

The relationship between route of administration and the adverse effects of amphetamine use (dependence symptoms, treatment-seeking, adverse psychological symptoms and violence) were examined among 231 Australian amphetamine users, half of whom usually injected amphetamine. Although 87% of users were recruited from non-treatment sources, a third had experienced symptoms of dependence on amphetamine, and a third had experienced an amphetamine-related health problem for which one in four had sought medical attention. There was also a high prevalence of psychological symptoms, such as depression, anxiety, paranoia, hallucinations and violence which were related to frequency of amphetamine use, and use by injection. Amphetamine users need to be better informed about the potential adverse effects of amphetamine use, and about ways in which they can reduce their risks of experiencing these harms by avoiding injecting use, and the regular use of high doses of amphetamines. 相似文献

A 79-year-old man noticed nasal obstruction and bleeding caused by a pedunculated tumor in the left nasal cavity. The tumor revealed a malignant neoplasm predominantly composed of immature neuroepithelial cells with rosettes and palisading patterns, rhabdomyoblastic cells with positivity for desmin and cross-striations, and immature mucin-producing glandular cells. Small amounts of mature chondroid tissue and neurofibrillary matrix were also present. Therefore, the tumor was diagnosed as nasal teratocarcinosarcoma. 相似文献

Inverse expression of Cdk4 and p16 in epithelial ovarian tumors 总被引:12,自引:0,他引:12
Sui L Dong Y Ohno M Goto M Inohara T Sugimoto K Tai Y Hando T Tokuda M 《Gynecologic oncology》2000,79(2):230-237
OBJECTIVES:The aim of this study was to elucidate the expression and the correlation of two cell cycle regulators, cdk4 and its inhibitor p16, in a series of benign, borderline, and malignant ovarian tumors and to evaluate whether their alterations correlate with clinicopathologial parameters and patients' prognosis in epithelial ovarian carcinomas. METHODS: Immunohistochemical analysis using anti-cdk4 and anti-p16 antibodies was carried out for 103 paraffin sections of ovarian tumors, and Western blot analysis and cdk4 activity assay were performed in 26 fresh ovarian tumor samples. RESULTS: The results of immunohistochemistry showed that 60.61 and 69.70% of benign, 69.57 and 56.52% of borderline, and 74.47 and 40. 43% of malignant tumors expressed cdk4 and p16, respectively, demonstrating increased cdk4 and decreased p16 expression in ovarian carcinomas. A significant inverse relationship between cdk4 and p16 expression was found. The loss of p16 expression was more correlated with G(2) and G(3) tumors in contrast with G(1) tumors. No significant correlation was observed between cdk4 expression and clinicopathological parameters. Neither cdk4 nor p16 expression has significant effects on overall survival by the Kaplan-Meier method. When the combined phenotypes of the two proteins were analyzed, patients with cdk4-positive/p16-negative expression had a reduced overall survival than other phenotypes of cdk4/p16. CONCLUSIONS: These data suggest that inverse expression of cdk4 and p16 may be involved in the development and progression of epithelial ovarian carcinomas. The combined phenotypes of cdk4 and p16 proteins could provide a useful prognostic indicator for patients with epithelial ovarian carcinoma. 相似文献

A 57-year-old woman was admitted to the hospital because of obstructive jaundice. Abdominal computed tomography and ultrasonography showed a homogeneous mass 7cm in diameter at the head of the pancreas. Gamma-scintigraphy showed uptake in the head of the pancreas. Histological diagnosis was obtained by endoscopic ultrasoundscopy-fine needle aspiration (EUS-FNA). The pathological and immunohistochemical studies showed diffuse lymphoma with large B-cells. We experienced a rare case of pancreatic malignant lymphoma and EUS-FNA was usefull in the diagnosis. 相似文献
