Grading of chronic synovitis—a histopathological grading system for molecular and diagnostic pathology
V Krenn, L Morawietz, T Häupl, J Neidel… - … -Research and Practice, 2002 - Elsevier
The following is a proposition for a simple histopathological classification system to measure
inflammation in synovial tissue. This synovitis-score is employed in conventionally stained
routine sections, and is applicable to every kind of synovitis, irrespective of etiology and
including the following relevant morphological alterations. First: hyperplasia/enlargement of
synovial lining cell layer. Second: activation of resident cells/synovial stroma. Third:
inflammatory infiltration. All defined histopathological qualities are graded from absent (0) …
