What term describes a fibrous tissue growth between digits?

• A. Interdigital fibroma
• B. Plantar fibroma
• C. Digital myxoma
• D. Osteophyte

Answer: (A)

Interdigital fibroma describes a fibrous tissue growth that occurs in the interdigital spaces between digits. This fibromatous mass specifically develops in the web space between toes (or fingers) and presents as a firm nodular lesion that may cause discomfort, especially with footwear. It is distinct from a plantar fibroma, which forms on the sole of the foot, not between digits; a digital myxoma, which is a mucinous tumor of a digit; and an osteophyte, which is a bone spur rather than fibrous tissue. Thus, interdigital fibroma is the term that best fits a fibrous tissue growth between digits.
