An eleven-year-old boy was seen by the general practioner due to a painfull hallux. The diagnosis unguis incarnatus was made. Therefore, a partial nail extraction was performed. Unfortunately, the patient still had complaints of a painful hallux and was forwarded to the surgical outpatient clinic. We saw a round, hard and benign tumor on the lateral side of the nail (picture 1). We performed a partial nail extraction as well. Due to persistence complaints and the abnormal course and X-ray was performed. On the X-ray an exostosis was seen (picture 2). This confirmed the diagnosis: subungual exostosis. It is a rare clinical manifestation and has a long delay up until diagnosis. It is a benign bone tumor and often seen on the hallux. A radical excision must be performed.
一名11岁男孩因拇趾疼痛就诊于全科医生。诊断为嵌甲。因此，进行了部分指甲拔除术。不幸的是，患者仍有拇趾疼痛的主诉，遂被转诊至外科门诊。我们在指甲外侧看到一个圆形、坚硬的良性肿瘤（图1）。我们也进行了部分指甲拔除术。由于症状持续以及病程异常，进行了X线检查。X线显示有骨赘（图2）。这证实了诊断：甲下骨赘。它是一种罕见的临床表现，诊断往往延迟较长时间。它是一种良性骨肿瘤，常见于拇趾。必须进行根治性切除。
