Magnetic resonance imaging revealed a 20 x 15 x 10 mm mass of low intensity on T1-weighted images (a, d) and high intensity on T2-weighted images (b, e) and gadolinium enhancement (c, f).

Magnetic resonance imaging (MRI) revealed a 2 x 1.5 x 1 cm mass of low intensity on T1-weighted images and high intensity compared with normal muscle on T2-weighted images and gadolinium enhancement (Figure 1). 2-[18F]-Fluoro-2 deoxy-D glucose positron emission tomography revealed increased uptake with a maximum standardized uptake value of 3.73 in the mass.
(a, b) The tumor adhered to the flexor digitorum profundus of both the third and fourth fingers.

The tumor had adhered to the flexor digitorum profundus of both the third and fourth fingers (Figure 2).
(a) The external surface of the mass was smooth and glistening without any gross abnormalities or disruption. (b, c) The lesion was well circumscribed and contained fibroblastic spindle cells. Elongated, slit-like spaces were prominent (hematoxylin-eosin, original magnification 20x, 400x).

The external surface of the mass was smooth and glistening without any gross abnormalities or disruption and measured 2.0 x 1.3 x 0.9 cm (Figure 3). Elongated, slit-like spaces were prominent (Figure 3). beta-Catenin immunohistochemistry showed no nuclear staining.
