is there any morphological differences between primary and secondary follicles?
Don't they both have germinal centers?
 
Reason I am asking is becausr hashimoto's thyroiditis exhibits secondary follicles, which are characterised as secondary. I was wondering how that would be different from primary lymphoid follicles morphologically speaking🙄
