- Probably can be considered a localized variant of PVNS.
Localized nodular synovitis, abbreviated LNS, is an uncommon pathology of the joint closely related to diffuse tenosynovial giant-cell tumour (also known as pigmented villonodular synovitis).[1]
General
Classification of PVNS:[2]
- Generalized.
- Local.
- Articular.
- Extra-articular.
Gross
Features:
- Location: fat pad inferior to patella.[3]
Microscopic
Features:[1]
- Similar to diffuse tenosynovial giant-cell tumour - see diffuse tenosynovial giant-cell tumour.
