What are the other cells present in classical Hodgkin’s disease
Lymphocytes
Eosinophils
Fibroblasts
What are the different types of Hodgkin’s disease based on
Differing proportions of Reed-Sternberg cells and lymphocytes
What is Lymphocyte rich Hodgkins
Few R-S cells and lots of lymphocytes
What is Lymphocyte depleted Hodgkins
Lots of R-S cells and few lymphocytes
What is Mixed cellularity Hodgkins
Roughly equal proportions of R-S cells and lymphocytes
What is Nodular sclerosing Hodgkins
As mixed cellularity, but different architecture
Are high grade lymphomas good or bad
bad
