About 90% of PTTs occur on the scalp. The sonographic findings of PTT in the subungual region have not been reported previously. In our case, sonography showed a heterogeneous mass containing echogenic foci with no detectable intratumoral vascularity. These echogenic foci probably represent keratin and cholesterol. \u00a9 2017 Wiley Periodicals, Inc. <jats:italic>J Clin Ultrasound<\/jats:italic> <jats:bold>46<\/jats:bold>:215\u2013217,
