摘　　要：目的探讨获得性指（趾）纤维角化瘤临床及病理特点。方法对确诊为获得性指（趾）部纤维角化瘤患者的临床表现、组织病理特点和治疗方法及转归进行分析。结果12例患者发病年龄17—64．5岁（39．75±17．69）岁，病程0．5—20年（4．83±5．77）年，男：女为1．4：1。皮损表现为多形态，主要累及指、趾、甲沟，也可累及非肢端部位。皮损组织病理检查：表皮角化过度和棘层肥厚，表皮突增宽呈分枝状，皮损中心由成熟的胶原束、成纤维细胞和大量扩张毛细血管组成。其中大部分胶原束与表皮相垂直走行，为其特征性表现。结论获得性指（趾）部纤维角化瘤是一种少见、原因不明的皮肤纤维组织良性肿瘤，多发于成年人指或趾，一般为单发，但也可发生于非肢端。采取手术或激光治疗，少有复发。Objective To investigate clinical and pathological characteristics of acquired digital fibrokeratoma （ADF）. Methods Clinical data were collected from 12 patients with ADF, and their clinical manifestations, histopathological features, treatment and prognosis were analyzed retrospectively. Results The mean age at onset of ADF was 39.75 ± 17.69 years （range, 17 - 64.5 years）, and the average disease duration was 4.83 ± 5.77 years （range, 0.5 - 20 years）. The ratio of male to female was 1.4∶1. Most skin lesions were polymorphic, and mainly involved fingers, toes and nail grooves. Sometimes non-extremity sites are also involved. Histopathological examination of skin lesions showed epidermal hyperkeratosis, acanthosis and broadened dendroid rete ridges. The dermis consisted of mature collagen bundles, fibroblasts and a large number of dilated capillaries. The characteristic manifestation was that most collagen bundles were vertical to the epidermis. Conclusions ADF, a rare benign fibrous tumor with unknown etiology, usually occurs in adults as a solitary lesion on fingers or toes, sometimes in non-extremity sites. Surgery and laser therapy are common treatments for ADF with low recurrence rate.
