What is the common name for interdigital fibroma?

• A. Corn
• B. Wart
• C. Granulation
• D. Laceration

Answer: (A)

Interdigital fibroma is a benign growth that forms between the digits and often presents as a firm, horn-like mass. Clinically, this appearance and its location lead clinicians to refer to it as a corn. A corn is a hard, keratinized callus that develops from chronic pressure or irritation, which matches why this interdigital mass is described that way. It isn’t a wart (which is viral and usually has a more wart-like surface), it isn’t granulation tissue (which is vascular and fleshy during wound healing), and it isn’t a laceration (a tear in tissue). So corn best fits the common name used for this interdigital lesion.
