Back to Diseases List

Overview

NCI Definition: A tumor usually arising in the synovium of joints, bursa or tendon sheath. It is characterized by the presence of mononuclear cells, multinucleated osteoclast-like giant cells, hemosiderin-laden macrophages, foam cells, and an inflammatory infiltrate. According to the growth pattern, it is classified as localized or diffuse. [1]

Tenosynovial giant cell tumors most frequently harbor alterations in NOTCH1, TP53, PDGFRA, NOTCH3, and MECOM [2].

Most Commonly Altered Genes in Tenosynovial Giant Cell Tumor

NOTCH1 Mutation, NOTCH1 Missense, TP53 c.217-c.1178 Missense, TP53 R175H, and TP53 Mutation are the most common alterations in tenosynovial giant cell tumor [2].
