Fig. 3: Additional histomorphologic features of CFTS.

From: Characterization of novel USP6 gene rearrangements in a subset of so-called cellular fibroma of tendon sheath

Fig. 3

CFTS with MYH9-USP6 fusion showing histomorphologic features of a nodular fasciitis in a central cellular area as well as b peripheral features a classic fibroma of tendon sheath. c CFTS with COL3A1-USP6 fusion showing enlarged multinucleated fibroblasts resembling floret cells. d CFTS in which no fusion was detected (Case 8) showing a cellular region with scattered eosinophilic cells similar to those seen in the tumor with PKM-USP6 fusion. Other regions of this tumor showed nodular-fasciitis like growth as well as peripheral features of classic fibroma of tendon sheath.
