TLDR A rare finger tumor was imaged, showing a unique pattern not seen before.
The document reported on a rare case of a proliferating trichilemmal tumor (PTT) located in the subungual region of a finger, which was unusual as 90% of PTTs typically occurred on the scalp. Sonographic imaging revealed a heterogeneous mass with echogenic foci, likely representing keratin and cholesterol, and no detectable intratumoral vascularity. This case was significant as it was the first to describe the sonographic findings of a PTT in this specific location.
