On physical examination, there was diffuse thickening, predominantly, of the radial and ulnar aspects of the PIP joint, without any skin pigmentation or neurological deficits (Figure 1).
Fusiform soft tissue swelling without joint space narrowing was observed in the PIP joint of the middle finger. There were no bony erosions or other structural abnormalities.

There were no bony erosions or other structural abnormalities (Figure 2).
The lesion indicated homogenous isointensity to the muscle on a T1-weighted image (a). On the postcontrast fat-saturated T1-weighted image, the lesion was heterogeneously hyperintense, and no other abnormal enhancement was noted (b).

No fresh or chronic hemorrhagic change was demonstrated (Figure 3).
The lesion was characterized by coarse fibrosis with adipose tissue, peripheral nerve fibers, and eccrine glands.

Histopathologically, the lesion was characterized by coarse fibrosis with adipose tissue, peripheral nerve fibers, and eccrine glands; this is compatible with a diagnosis of PDD (Figure 4).
At the latest follow-up, no recurrence was observed in his middle finger.

At the latest follow-up, 3 years postoperatively, no recurrence was observed in his middle finger, and he was very satisfied with the outcome, both cosmetic and functional ones (Figure 5).
