We report the case of a painless deforming subungual mass at the nail tip, progressively enlarging over three months. Radiographs showed an extra-osseous ossification. Intraoperatively this was found to be a bony mass arising from the sterile matrix. Unusual extra-osseous ossification in the finger is rare and this case highlights the need of this benign lesion to be considered when a patient presents with finger swellings.
我们报告了一例发生在指尖的无痛性变形甲下肿物病例，该肿物在三个月内逐渐增大。X线片显示为骨外骨化。术中发现这是一个起源于无菌甲床的骨性肿物。手指出现不寻常的骨外骨化情况较为罕见，该病例强调了在患者出现手指肿胀时需要考虑这种良性病变。
