Where are interdigital fibromas located?

• A. On the dorsal aspect of the paw
• B. Between digits
• C. Within the digital tendon sheath
• D. In the nail bed

Answer: (B)

Interdigital fibromas are fibrous masses that develop in the interdigital web spaces of the paw—the area between the toes. The word “interdigital” literally means between digits, so the correct location is between the digits themselves. They are not located on the dorsal surface of the paw, not inside the digital tendon sheath, and not in the nail bed, which would involve different tissues and disease processes. This specific interdigital location explains why these lesions present between the toes and helps distinguish them from other potential paw lesions.
