Fibrous Tissue Abnormalities – Subungual Exostosis
Subungual Exostosis is a benign fibrous tissue abnormality that I occasionally encounter in both my The Woodlands and Conroe dermatology offices. Clinically, Subungual Exostosis appears as a protrusion from below the end of the nail plate on the fingers and/or toes. Subungual Exostosis is most often found in women and appears pink to flesh colored. Over time as the lesion grows, the nail plate can become brittle and break. Subungual Exostosis can become over 1cm in size. Treatment involves excision of the lesion.
