Medicine:Aponeurotic fibroma

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.
