Histopathology of a calcifying aponeurotic fibroma from a finger, H&E stain.

Aponeurotic fibroma, also known as calcifying aponeurotic fibroma, and juvenile aponeurotic fibroma is characterized by a lesion that usually presents as a painless, solitary, deep fibrous nodule, often adherent to tendon, fascia, or periosteum, on the hands and feet. The World Health Organization in 2020 reclassified aponeurotic fibroma nodules as a specific benign type of the fibroblastic and myofibroblastic tumors. Aponeurotic fibromas are diagnosed based on histopathology and treated by surgical excision. They are more common in males than females.
