UNLABELLED The aim of this study was to investigate the clinicopathological features of nine unusual vascular tumors of the female genital tract and to investigate the problems in the differential diagnosis from other genital lesions. MATERIAL-METHODS In a review of 15,000 specimens of the female genital system examined in our Laboratory during the last(More)
During the last 15-year period in our laboratory, 14 cases of malignant change of endometriosis were diagnosed in women 37-70 years of age. Seven cases were adenocarcinomas, one case was an adenosarcoma and six cases presented the morphology of endometrial stromal sarcoma. Eleven cases developed in various sites of the genital system (5/11 in the ovaries,(More)
AIM The aim of this study was to investigate the relationship between adenomyosis, endometrial adenocarcinoma, hyperplasia and uterine leiomyomas. MATERIAL AND METHODS 135 consecutive hysterectomy specimens showing adenomyosis and 82 consecutive cases of endometrial adenocarcinoma were studied in our laboratory in the last 5-year period. The histological(More)
UNLABELLED The aim of the study was to review patients with metastatic ovarian tumors in relation to their outcome and clinical characteristics. METHODS It was a retrospective study including 83 patients with histopathological diagnosis of metastatic ovarian tumor. The examined parameters include age of the patients, origin of the tumor, consistency and(More)
BACKGROUND Treatment with lung volume reduction coils (LVRC) may be effective in patients with severe heterogeneous emphysema and incomplete fissures. OBJECTIVE We hypothesized that LVRC placement improves pulmonary function, exercise tolerance and quality of life in these patients. METHODS Twenty-six patients with chronic obstructive pulmonary disease(More)
Three patients (2 male and 1 female) undergoing maintenance hemodialysis for more than 4 years with tumoral calcifications were treated by sodium thiosulfate. All patients had periarticular and soft tissue calcification. A considerable regression of calcified masses with concurrent clinical improvement was noted in 2 of the 3 patients.
PURPOSE To further study the clinicopathologic and immunohistochemical features of ovarian granulosa cell tumors (GCTs). METHODS We retrospectively studied all cases of GCTs diagnosed in our laboratory over the last 10-year period. Immunohistochemistry for inhibin, vimentin, cytokeratin, Ki-67 and p53 was performed on archival paraffin blocks. Pathologic(More)
BACKGROUND One of the most common forms of pulmonary hypertension (PH) is that associated with chronic obstructive pulmonary disease (COPD). So far, patients with severe emphysema and established PH have been excluded from endoscopic lung volume reduction (ELVR) therapy due to the risk of right heart decompensation. OBJECTIVE The aim of this pilot study(More)
INTRODUCTION Valve implantation has evolved as a therapy for patients with advanced emphysema. Although it is a minimally invasive treatment, it is associated with complications, the most common being pneumothorax. Pneumothorax occurs due to the rapid target lobe volume reduction and may be a predictor of clinical benefit despite this complication. (More)
Six cases of extraovarian cystic tumors of mullerian type are reported. Patient age ranged from 27-71 years. Tumor diameters were 5-11 cm and were located in the mesentery (4/6) and retroperitoneum (2/6). Four tumors were of mucinous type (1/4 of borderline malignancy) and two of serous type. These tumors clinically and histopathologically mimic other(More)
