Tenosynovial giant cell tumor, localized type
Definition
A well-circumscribed, lobulated tumor, completely or partially covered by a fibrous capsule. It usually arises in the fingers. It is characterized by the presence of mononuclear cells, multinucleated osteoclast-like giant cells, hemosiderin-laden macrophages, foam cells, and an inflammatory infiltrate. The tumor is slow-growing, usually developing over several years. Clinical presentation includes painless edema of the affected site.
