Which term describes a lesion that occurs between digits?

• A. Interdigital fibroma
• B. Osteophyte
• C. Hemangioma
• D. Tenosynovitis

Answer: (A)

Interdigital means between digits, and fibroma indicates a benign fibrous tissue mass. Put together, interdigital fibroma describes a fibrous lesion located in the interdigital space, i.e., between digits. That's exactly what the question is asking for—a lesion occurring between digits.

The other terms don’t specify a location between digits: an osteophyte is a bone spur, not defined by its position between fingers or toes; a hemangioma is a vascular tumor; and tenosynovitis is inflammation of a tendon sheath. None of these inherently describe a lesion specifically between the digits, so they aren’t the best fit.
