Figure 3a.   Palmar fibromatosis. (a) Clinical photograph shows multiple subcutaneous cords and nodules (arrowheads) at the bases of the second through fifth digits, which resulted in flexion contractures. (b, c) Axial (b) and sagittal (c) T1-weighted magnetic resonance (MR) images (repetition time msec/echo time msec = 633/20) obtained in another patient show the fibromatosis as a low-signal-intensity band (arrowheads) superficial to and paralleling the flexor tendon (arrow) of the fifth digit.
