Fig. 4: Diagram showing the spectrum of fibroblastic/myofibroblastic tumors so far described with USP6 gene rearrangements and their respective fusion partners.

In our series, we describe six different fusion partners in a subset of CFTS, three of which are novel (highlighted in purple). Key: ABC aneurysmal bone cyst, CF cranial fasciitis, CFTS cellular fibroma of tendon sheath, FOPD fibro-osseous pseudotumor of digits, MO myositis ossificans, NF nodular fasciitis.
