case_images: 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).
case_images: 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.

case_images: There were no bony erosions or other structural abnormalities (Figure 2).
case_images: 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).

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

case_images: 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).
case_images: At the latest follow-up, no recurrence was observed in his middle finger.
