By application of morphological and ultrastructural methodsnosis. The pathogenesis of MDS is still unclear. It has been for identification of apoptosis, we analyzed the incidence of found that oncogene dysregulation is the basis of the disease. and two (6.8%) had refractory anemia with excess of blasts
Between 2% and 9% of malignant tumours are metastasizing to the skin. Cutaneous metastases from carcinoma of the prostate occur infrequently. Their presence is associated with poor prognosis. We report the case of a 65-year-old man with carcinoma of the prostate, presenting multiple metastases in the scrotal skin region.
T-cell-rich B-cell lymphoma (TCRBCL) is a recently recognized and ill-defined form of non-Hodgkin's lymphoma (NHL), with no generally accepted diagnostic criteria and with limited information regarding its incidence, cellular origin, morphologic spectrum and biologic behavior. The recent findings suggest that TCRBCL could be a biologically distinct disease characterized by male preponderance, advanced-stage disease initially and high incidence of extranodal localization, especially in the bone marrow. For the time being, proper diagnosis rests on the immunohistochemical identification of the scattered large malignant B-cells amid a sea of small reactive T-lymphocytes. In this study, the clinicopathologic features of 8 patients (pts) with TCRBCL are presented. The male to female ratio was 5/3, and the median age was 52 years (32-67). The disease was advanced in most patients: 5 pts with stage IV and 2 pts with stage III. The patients presented with generalized lymphadenopathy (5), splenomegaly and/or hepatomegaly (4) and bone marrow involvement (4). The diagnosis of TCRBCL was initially established in 6 pts, while the remaining 2 pts were initially diagnosed as having Hodgkin's disease (of mixed cellularity in 1 pt and lymphocytic predominance in another). Revision of the 2 samples comprising immunohistochemistry enabled diagnosis of TCRBCL. Immunohistomorphologically the present series can be differentiated from other types of lymphoma such as lymphocyte-predominant Hodgkin's disease and peripheral T-cell lymphoma.
Radical prostatectomy represents an optimal therapeutic method in treatment of the localized prostatic carcinoma. It may be performed using retropubic, perineal, transcoccygeal or laparoscopic approach. In a multicenter study, the authors have analyzed 127 patients surgically treated in the period 1992 - 2003. All the patients were preoperatively diagnosed with the localized prostatic carcinoma. The patients were operated at the Clinic of Urology in Belgrade (92 patients) and other departments of urology in Serbia (35 patients). The youngest patient was 49 while the oldest one was 75 (mean age 64 years). The surgical procedure duration ranged between 60 and 120 minutes. Over the last five years, the need for blood transfusion was below 50%. All the patients underwent retropubic radical prostatectomy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
