An 86-year-old woman presented with a slowly growing, painless, smoothsurfaced mass on the left third toe, measuring ca. 1.0 × 0.5 × 0.5 cm). The mass was surgically resected. Histological examination revealed a storiform dermal tumor (i.e., one with a rope-like or whorled configuration) consisting of spindle cells without atypia or mitoses. This a periungual fibroma, a benign mesenchymal tumor
