Interdigital fibromas are most accurately described as which of the following?

• A. Benign soft tissue tumors
• B. Malignant soft tissue sarcomas
• C. Malignant bone tumors
• D. Inflammatory conditions

Answer: (A)

Interdigital fibromas are benign soft tissue tumors arising in the interdigital spaces. They are composed of fibrous connective tissue, forming slow-growing, well-demarcated masses that originate in soft tissue rather than bone. Because they do not invade nearby structures or spread to other parts of the body, they are classified as benign soft tissue tumors. This sets them apart from malignant soft tissue sarcomas, which are aggressive and can metastasize, from malignant bone tumors, which originate in bone, and from inflammatory conditions, which involve active inflammation rather than a discrete fibrous mass.
