[1] The World Health Organization in 2020 reclassified aponeurotic fibroma nodules as a specific benign type of the fibroblastic and myofibroblastic tumors.

Aponeurotic fibroma occurs most frequently in the fingers, palms, and soles of the distal extremities.

[3] Typically, the tumor is defined as a smaller than 3 cm diameter, firm, non-tender mass that grows slowly.

[3] Imaging results include edematous alterations and subcutaneous neoplastic tumors with hazy margins that appear to be encroaching on the surrounding tissues.

The tumor often manifests in the first or second decade of life, while examples have been documented at birth and 67 years of age.
