一位 86 歲的婦女進來時，她的左第三個腳趾上有一個緩慢生長的無痛腫塊，大小約為 1. 0 × 0. 5 × 0. 5 厘米。透過手術切除了腫塊。顯微鏡下檢查顯示真皮腫瘤呈繩狀或螺旋狀，由梭形細胞組成。沒有異常變化或細胞分裂。這稱為甲週纖維瘤，是結締組織的非癌性生長。
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
