To analyze the ultrasonography of pr imary malignant mesothelioma.Method:Comparing the pictures from ul-trasound,eight primary malignant m esothelioma cases proved by operation or autopsy were reviewed.Result:The result showed the char-acteristics of primary malignant me sothelioma from ultrasonography as following:â‘ The parietal peritoneum was thicken ed like placen-ta,and the visceral peritoneum was a lso thickened.It was often shown that the digestive system and intestinal loops were surro…
To prove up the cause of high incidence of malignant mesothelioma in population of Da Yao county in Yunnan province Methods A retrospective cohort study is implemented to collect subjects of exposured population and controlled population The comection between incidence of maligmant mesothelioma andexposure to smoking, environmental tobacco smoking, familial history of neoplasms and consumption of tea are analyzed Three subcohort sourced from dead subjects are set up to analyze th…
Aim: To explore and compare the clinical diagnostic importance of MRI versus CT in malignant pleural mesothelioma. Methods: Twenty-five cases of malignant pleural mesothelioma were verified by histology or cytology. All of them were examined with both MRI and CT. The imaging characteristics and their clinical diagnostic importance were analysed comparatively. Results: Except for the experssivity of calcification of tumor, MRI had commonly superior detection and evaluation of morphology …
Objective To improve our knowledge of clinical features, diagnostic and therapeutic methods of diffuse malignant peritoneal mesothelioma(DMPM) in women.Methods Through analyzing the ways of diagnosis and the course of treatment in 5 cases of female DMPM hospitalized from 1990 to 2000, we summarized its general diagnostic and therapeutic procedures.Results Clinical manifestations of this disease were acute and chronic abdominal pain, distension, intraperitoneal and pelvic masses, ascites. Spontaneous r…
Background: Cutaneous mesothelioma is rare but may occur following local surgical procedures for visceral mesothelioma or as a metastasis.Methods: A patient with pleural mesothelioma, who developed papules within chest wall scars, 14 and 15 months after pleural biopsy and thoracentesis, respectively, is reported.Results: Histopathology showed an epithelioid tumor forming tubulopapillary and glandular structures.The diagnosis of mesothelioma was confirmed with immunohistochemistry.Tum…
To evaluate medical thoracoscopy in the diagnosis and treatment of pleural mesothelioma. Twenty-one patients with pleural mesothelioma were studied, 17 male and 4 female, with a mean age of (62±12) years. All were brought into medical thoracoscopy after three consecutive pleurorrhea cytology and percutaneous pleural biopsy. The patients with diffuse pleural mesotheloima underwent pleurodesis after thoracoscopy. The diagnostic yield of all three techniques compared, complications and the effect …
Objective To investigate differential diagnosis of mesothelioma by means of the combined examinations of sections and smears of the deposits of pleural and peritoneal effisions.Methods Successive sections and smears of the deposits of 52 cases of mesothelioma were studied,in which 46 cases were testified by histology and 6 cases had typical clinical characteristics.Results All of 52 cases of mesothelioma were detected by means of section method,while only 38 cases were detected by means of smear method,its …
Objective To study the presence of simian virus-40(SV40)DNA in tissue sections of malignant mesothelioma and to evaluate the relation of prognosis. Methods We reviewed 60 cases of malignant mesothelioma confirmed by the methods of histology,immunohistochemistry and electron microscopy.The polymerase chain reaction was applied to detect the presence of SV40 DNA in tissue sections of malignant mesothelioma.Results SV40 DNA was detected in the tissue of malignant mesothelioma(60%).We al…
Malignant pleural mesothelioma(MPM),originated from pleural mesothelium cell,is a fatal tumor with atypical manifestation and poor clinical outcome.Here we present a review of the manifestations of MPM by several imaging methods(X-ray,CT,MRI and PET/CT),with a discussion in the values of thoses methods in the diagnosis,staging and prognosis of pleural mesothelioma.
To study the pathological diagnosis,differential diagnosis and prognosis of lymphohistiocytoid mesothelioma(LHM).Methods Histopathological characteristics and immunohistochemical findings were studied in two cases of LHM with review of the literatures.Results Paients presented with chest pain in two cases.The tumors showed a diffuse proliferation of large,atypical fibrohistiocytoid cells intermixed with numerous lymphocytes,plasma cells and occasional eosinophils.Ultrastructurally,the cases …
