The results of immunohistochemical staining in reactive and neoplastic hematopoietic disorders are summarized in Table 1. Characterization and distribution of an oncofetal antigen M2A antigen expressed on testicular germ cell tumours. In this study, we investigated the expression patterns of podoplanin using a new mouse monoclonal antibody D, and compared them with CD21, a well-established FDC marker, in a comprehensive panel of cases. Perez Ordonez B, Rosai J. Our study revealed that D strongly stained 3 of 4 FDC sarcomas. Other cancers 4 oesophagus, 4 cervix uteri, 2 endometrial, 3 gastric, 1 colon, 1 pancreas, 1 prostate, 1 melanoma.

Monoclonal antibody D, a new marker of lymphatic endothelium, reacts with Kaposi’s sarcoma and a subset of angiosarcomas. The screen of the device must have a resolution of at least pixels horizontally and pixels vertically. September 12, Date written: This page last revised 6.

Benign primary adnexal tumour. In these circumstances, you must negotiate with your tutor to get their agreement to submit your assignment on paper. March 15, Date written: No expression of podoplanin was detected in normal or neoplastic lymphoid and myeloid cells. stufy

Consider systemic and sociocultural issues in a counselling case study. FDCs participate in the fase center reaction by preventing apoptosis of germinal center B-cells and by stimulating cellular interactions and proliferation [ 12 ]. Other antibodies are shown for comparison. A novel diagnostic immunohistochemical marker.

Further studies with more cases cas needed to confirm our findings. Clinical, pathologic, and histogenetic characteristics of an underrecognized disease entity. Employer sponsorship Studying with The Open University can boost your employability.

Although D appears to be highly sensitive for the diagnosis of FDC sarcoma, it is well known that D also stains several other types of spindle cell sarcomas, such as angiosarcoma and Kaposi’s sarcoma [ 2122 ].

Significance of lymph vessel invasion identified by the endothelial lymphatic marker D in node negative breast cancer. Although most occur in lymph nodes, about one-third of them are located in extranodal sites [ 6 ].

Kaposi sarcoma stains, suggesting derivation from lymphatics. See the satisfaction survey stduy for this course. Castleman’s disease, hyaline vascular type: Support Center Support Center. Finding time to study Is my English good enough?

March 20, Date written: What you will study There has been tremendous growth in counselling since the late s, with huge numbers of people seeking help in individual counselling, in group therapy sfudy through related ‘self-help’ books. Interdigitating dendritic cells IDCwhich were identified by positive staining for S protein, were negative for D Figure 3. Follicular dendritic cells FDCs are stromal cells unique to primary and secondary lymphoid follicles. Find your personal contacts including your tutor and student support team:.

Marked nuclear pleomorphism and high mitotic count are seen in this case. In vitro studies indicated that podoplanin is involved in mediating cell motility by promoting rearrangement of the actin cytoskeleton [ 13 ]. NY Find articles by Lugen Chen. This study was based on cell blocks prepared from serous effusions 3. The biological function of podoplanin is poorly understood. d420

Results Comparison of D and CD21 Immunohistochemical Staining in Reactive and Neoplastic Hematopoietic Disorders The results of immunohistochemical staining in reactive and neoplastic hematopoietic disorders are summarized in Table 1.

Clinicopathologic analysis of 17 cases suggesting a malignant potential higher than currently recognized. We confirmed that podoplanin, as detected by the D monoclonal antibody, is expressed in FDCs. Clusterin expression distinguishes follicular dendritic cell tumors from other dendritic cell neoplasms: Podoplanin, D, follicular dendritic cell, follicular dendritic cell sarcoma.
