Which statement best describes interdigital fibromas?

• A. They are fibrous tissue growth between digits
• B. They are malignant bone tumors
• C. They are vascular malformations
• D. They are inflammatory joint diseases

Answer: (C)

Interdigital fibromas are benign fibrous tissue proliferations that develop in the interdigital space of the hoof or claw. They arise from chronic irritation or mechanical stress and are composed mainly of dense fibrous connective tissue, not abnormal blood vessels or inflammatory tissue. That makes them a fibrous tissue growth between digits rather than a vascular malformation, an inflammatory joint disease, or a malignant bone tumor. Clinically, you’d expect a firm, nodular mass between the digits that can cause discomfort or lameness, and treatment typically involves surgical removal or debulking of the mass. The other options describe entities with vascular, inflammatory, or malignant bone characteristics, which do not fit interdigital fibromas.
