Proliferating trichilemmal tumor (PTT) is a rare tumor that originates from the outer root sheath of a hair follicle. 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. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 46:215-217, 2018.
增殖性外毛根鞘瘤(PTT)是一种起源于毛囊外根鞘的罕见肿瘤。约90%的增殖性外毛根鞘瘤发生于头皮。此前尚未有关于甲下区域增殖性外毛根鞘瘤的超声检查结果报道。在我们的病例中,超声检查显示一个不均质肿块,内含高回声灶,肿瘤内未检测到血管。这些高回声灶可能代表角蛋白和胆固醇。© 2017威利期刊出版公司。《临床超声杂志》46:215 - 217,2018年。
