2/81. Bilateral inflammatory breast metastases of epithelial ovarian cancer.Metastases to the breast are rare. Secondary breast involvement from an epithelial ovarian cancer heralds widespread dissemination and a very poor prognosis. We report an unusual case of a patient who had epithelial ovarian cancer and who showed signs of recurrence with inflammatory metastases to both breasts, 2 years after her diagnosis of ovarian cancer. She died within 3 months of breast involvement. Our case has unique features, with both bilateral breast metastases and also with its inflammatory pattern of metastasis, which is extremely rare.- - - - - - - - - - ranking = 1.75keywords = cancer (Clic here for more details about this article) |
3/81. Report of a fatal case of dengue infection with hepatitis: demonstration of dengue antigens in hepatocytes and liver apoptosis.A fatal case of dengue (DEN) infection associated with a spleen rupture and with hepatitis is reported here. Microscopic studies showed numerous areas of spleen rupture with hematomas and revealed necrotic foci in liver samples obtained at autopsy. Although hepatitis was reported in several cases of DEN fever, the mechanism of liver injury remains poorly understood. In this case, immunohistochemistry showed that DEN viral antigens were mostly detected in hepatocytes surrounding the necrotic foci. By in situ detection of dna fragmentation, apoptotic hepatocytes were found to be colocated with DEN virus-infected hepatocytes. These findings suggest that hepatocytes are the major sites of DEN virus replication in the liver and that DEN virus induces apoptosis of hepatocytes in vivo.- - - - - - - - - - ranking = 0.61864653013984keywords = spleen (Clic here for more details about this article) |
4/81. Intracranial inflammatory tumors: a survey of their various etiologies by presentation of 5 cases.Due to similar clinical and neuroradiological features, intracranial inflammatory tumors (IITs) are frequently misdiagnosed as brain neoplasms, from which they notably differ in respect to therapy and prognosis. In this article, five cases of such tumors are presented. Three of the patients with brain tumors (cases 3, 4 and 5) presented a history of 'pararheumatic' syndromes but no diagnosis of defined immunopathies. On the basis of radiological findings, all processes were classified as genuine brain neoplasms, but histology showed reactive inflammatory features. The possible etiologies of these 'tumors' are discussed on the basis of all clinical and histological data of the patients. The spectrum of diseases potentially leading to the manifestation of an IIT is reviewed. Additionally, the presentation of case 5, who developed a highly malignant B-cell-lymphoma 6 months after the removal of an IIT without any histological signs of atypia, shows that this differential diagnosis always has to be kept in mind.- - - - - - - - - - ranking = 0.25207070538273keywords = neoplasm (Clic here for more details about this article) |
5/81. immunotherapy of cancer patients with bacillus Calmette-Guerin: summary of four years of experience in japan.Active immunotherapy with living BCG was conducted on 98 patients with various types of cancer. The candidates for this therapy were patients with residual or inoperable cancer of the colorectum, liver, breast, biliary tract, lung, and other organs with a follow-up of 4-58 months. Eleven of the 98 (11%) were able to survive for as long as 37-58 months (mean survival time 42.5 months) because of this treatment and are still living. Another 11 patients are also alive more than 24 months after starting treatment. Thirty-seven patients, however, succumbed within 12 months despite BCG immunotherapy. On the other hand, 37 patients in the control group, who shared the same clinical status and did not receive BCG therapy during this period, underwent unhappy courses for 2-12 months (mean survival time 8.7 months). The pretreatment immunoresponsiveness of these 98 patients was suppressed, as measured by the following immunologic parameters: T-cell subpopulation in the peripheral blood, stimulation index of PHA, and skin tests to DNCB, KLH, PPD, and PHA. All of these parameters improved shortly after initiation of BCG injections in 22 patients who survived more than 24 months. In contrast, in patients who died within 12 months, immunoresponsiveness remained suppressed throughout the course. This result has suggested that there was an apparent correlation between the effectiveness of BCG and immunoresponsiveness. In addition, a good correlation was observed between the duration of inflammatory reactions at BCG injection sites and clinical prognoses. Moreover, it was shown that a relatively high amount of BCG (20-80 mg as an initial dosage) and repeated injections of living BCG were necessary to obtain a sufficient enhancing effect on the immunocompetency of these late-stage cancer patients. The most conventional criterion used to determine an optimal time for booster injections of BCG was measurement of the PPD-evoked skin reaction at the BCG injection site, that is, Koch's phenomenon. When a marked flare-up reaction of more than 2.5 X 2.5 cm in size was observed, the effect of BCG was considered to be continuing, and no additional booster injection was needed. The mean interval between the first and second BCG injections was 6.2 /-1.1 months in patients who survived more than 2 years. In contrast, the duration of this reaction was only transient in ineffective cases. The most frequent side effects of this therapy were fever and malaise; these complications occurred in 62% of the cases. No severe side effects, such as dissemination, anaphylactic shock, or granulomatous hepatitis, have been experienced throughout this study, even in patients to whom a total dosage of more than 200 mg of living BCG were injected.- - - - - - - - - - ranking = 1.75keywords = cancer (Clic here for more details about this article) |
6/81. A case of inflammatory breast cancer following augmentation mammoplasty with silicone gel implants.A 54-year-old-woman who underwent augmentation mammoplasty with silicone gel implants 30 years previously, visited our hospital with complaints of bloody nipple discharge, redness and itching of her right breast. Cancer of the right breast was diagnosed by dynamic magnetic resonance imaging (MRI) examination with gadolinium (Gd)-DTPA enhancement. Radical mastectomy was subsequently performed. The histopathological findings demonstrated scirrhous and inflammatory breast cancer with invasion of dermal lymphatics.- - - - - - - - - - ranking = 1.25keywords = cancer (Clic here for more details about this article) |
7/81. Mass-forming inflammatory periductal fibrosis mimicking hilar bile duct carcinoma.A case of a rare benign biliary lesion at the hepatic hilum mimicking hilar bile duct carcinoma is reported. A 73-year-old man was found to have gastric cancer by gastrointestinal fiberscopy. Dilated right intrahepatic bile ducts and a 2-cm mass in the right hepatic duct were demonstrated by further imaging investigations. He was finally diagnosed as having hilar bile duct and gastric carcinomas, and underwent right portal vein embolization followed by a single-stage extended right hepatectomy and total gastrectomy. Pathologically, however, the lesion in the right hepatic duct showed inflammatory changes with periductal fibrosis, without any signs of malignancy. A literature search revealed 11 such cases including the present one.- - - - - - - - - - ranking = 0.25keywords = cancer (Clic here for more details about this article) |
8/81. Early small cell lung cancer with extensive inflammation and scar formation.A 56-year-old man, at one year before his first visit to our hospital, had presented cough, stridor and chest pain, and expectorated a mass, resulting in prompt disappearance of the symptoms. He was afflicted with recurrent symptoms, and the bronchoscopy showed a polypoid tumor occluding the right lower bronchus. The tumor was resected via bronchoscopy, which revealed histologically small cell carcinoma with significant inflammation and scar formation. The tumor was macroscopically the same as the one that had been expectorated by the patient at one year previously. A right lower lobectomy was conducted, but the specimen demonstrated no residual tumor. Tumor invasion into the bronchial wall was therefore limited within the submucosal layer for more than a year. Finally, the present tumor was diagnosed as an early small cell lung cancer with a characteristic of self involution. With no adjuvant treatment, the patient is well without tumor recurrence at 3 years to date after the surgery.- - - - - - - - - - ranking = 1.25keywords = cancer (Clic here for more details about this article) |
9/81. Inflammatory myositis: a rare differential diagnosis of a neck lump.Inflammatory myositis is an extremely rare benign inflammatory condition of skeletal muscle. It usually affects the extremities, and there are only 10 cases reported in the head and neck region. Its significance is that in this region it can be clinically mistaken for a neoplasm. We describe a case and review the literature.- - - - - - - - - - ranking = 0.12603535269137keywords = neoplasm (Clic here for more details about this article) |
10/81. Treatment of metastatic melanoma with autologous, hapten-modified melanoma vaccine: regression of pulmonary metastases.A human cancer vaccine composed of autologous tumor cells modified with the hapten dinitrofluorobenzene (DNP) induces cell-mediated immunity to the tumor cells and the development of inflammatory responses within metastatic sites. In this study we determined whether DNP vaccine could induce regression of established metastases. Ninety-seven patients (83 evaluable) with surgically incurable metastatic melanoma were treated with DNP vaccine preceded by low-dose cyclophosphamide. Tumor regression was assessed by standard criteria. The development of cell-mediated immunity to melanoma-associated antigens was measured by delayed-type hypersensitivity (DTH) testing before and after DNP vaccine treatment. survival analysis was performed by the Kaplan-Meier method. There were 11 antitumor responses: 2 complete, 4 partial and 5 mixed. Both complete responses and 2 of the 4 partial responses occurred in patients with lung metastases. Response durations were as follows: partial responses-5, 6, 8 and 47 months; and complete responses-12 and 29 months. Tumor regression required at least 4 months to become evident and in 2 cases maximum regression was not observed until 1 year after beginning treatment. patients who exhibited tumor regression survived longer than those who did not (median survival times: responders, 21.4 months; non-responders, 8.7 months; p = 0.010). DTH to DNP-modified and unmodified autologous melanoma cells was induced in 87% and 42% of patients, respectively. The DTH response to unmodified cells was significantly associated with prolonged survival. Autologous DNP-modified melanoma vaccine can induce clinically meaningful regression of metastases and small lung metastases appear to be unusually sensitive. The development of DTH to unmodified, autologous tumor cells may be an important indicator of the vaccine's efficacy.- - - - - - - - - - ranking = 0.25keywords = cancer (Clic here for more details about this article) |
