The grades of lymphoid neogenesis in idiopathic dacryoadenitis. a Grade 1 was defined as lymphocytic aggregates corresponding to 10–20 radial cell counts (arrow). b Grade 2 was defined as more than 20 radial cell aggregations but without GC-like structure formation (arrow). c Grade 3 was defined as massive lymphocytic aggregates with GC-like structure formation (arrows indicate the localization of GC-like structure).
