Giant cell tumour of tendon sheath is a relatively common tumour of small joints. It is grouped with the chondro-osseous tumours. It is abbreviated GCT of tendon sheath.
Fibroma of tendon sheath (abbreviated FTS) redirect to this article.
General
- Can be thought of as the small joint version of diffuse tenosynovial giant-cell tumour (AKA PVNS).[1]
- Rarely recur.
- Classically afflicts the hand.[2]
- Rarely malignant.[3][4]
Gross
Features:[2]
- Circumscribed mass - yellow-brown to tan.
Note:
- May be associated with bony erosions in larger lesions.[2]
Image:
Microscopic
Features:[1]
- Foam cells.
- Cells with moderate to abundant foamy-appearing cytoplasm.
- Multinucleated giant cells - may be scarce.
- +/-Tendon.
- Dense connective tissue.
- +/-Hemosiderin-laden macrophages.
Note:
- Features of malignancy: nuclear pleomorphism,[4] abnormal mitoses, >10 mitoses/HPF, tumour necrosis lack of maturation to superficial part (nuclei shrink, cytoplasm lipid-ified).[1]
DDx:
- Giant cell lesions.
- Plexiform fibrohistiocytoma.[citation needed]
- Fibroma of tendon sheath (FTS) - if one believes it is a separate entity.[6]
- IHC suggests FTS and GCT of tendon sheath are one entity.[7]

Micro
The sections show histiocytes and rare multinucleated giant cells on a background of dense connective tissue compatible with tendon. No nuclear atypia is apparent. Rare mitotic activity is identified. No atypical mitoses are apparent.
Alternate
The sections show histiocyte-like cells and rare multinucleated giant cells on a background of dense connective tissue compatible with tendon. Hemosiderin-laden macrophages are present. No nuclear atypia is apparent. No mitotic activity is apparent.
