anonymous Rosai-Dorfman disease confirm with imunostain for S100 protein which highlights the large histiocytes  100

anonymous Rosai Dorfman's disease. (100%) Do S100 protein stain to confirm the nature of the histiocytes.  100
anonymous Axillary nodule - Rosai-Dorfman's disease (= sinus histiocytosis with massive lymphadenopathy 100% For confirmation by S-100 protein immunostaining of the histiocytes.  100
anonymous Extranodal Rosai-Dorfman's disease, 100% The SHML cells can be highlighted by S100 stain immunohistochemically.  100
anonymous EXTRANODAL ROSAI DORFMAN'S DISEASE 100% SUGGEST S100 PROTEIN TO CONFIRM DIAGNOSIS  100
anonymous Rosai Dorfman disease. Perform special stains to exclude infectious agents.  100
anonymous Rosai-Dorfman Disease Suggest immunohistochemical stain for S-100 protein which is positive in Rosai-Dorfman disease. Also suggest PAS and ZN stains to rule out infectious diseases.  100

anonymous Rosai-Dorfman Disease Confirmed by immunohistochemistry (S100+)  100
anonymous Extranodal Rosai-Dorfman disease. 100% Probability nil  100
anonymous Sinus histiocytosis with massive lymphadenopathy 100% nil  100
anonymous EXTRANODAL ROSAI-DORFMAN DISEASE nil  100
anonymous Inflammatory lesion with plasmacytosis and numerous foamy histiocytes. Need stains to exclude infection and need to correlate with clinical features.  30
