A small polypoid lesion was removed from the incisive papilla region of a healthy female aged 8 years. It was composed of non‐cycling smooth muscle fibres that were immunoreactive for various muscle antigens, surrounded by basement membrane containing collagen IV, arranged as bundles and mixed with CD34(+) interstitial cells, mast cells, dendrocytes and nerves. The lesion could be attributed to dysgenesis affecting media of vessels emerging from the incisive foramen. Intra‐oral smooth muscle hamartomas tend to favour regions featuring complex developmental events.
