Intradermal nodular fasciitis of the ear auricle: A case report and literature review

Introduction: Nodular fasciitis (NF) is a benign self-limited neoplasm of fibroblastic and myofibroblastic derivation. It primarily arises within the subcutaneous tissue. It arises less frequently in the skeletal muscle, and very rarely in the skin. Nodular fasciitis of the ear is very rare with only seven publications including one case series of 50 cases, of which only 6 arising from the auricle or pinna are reported in total. Moreover, intradermal NF is itself an extremely rare entity with only 36 reported cases in literature.
