Onychomatricoma is a rare and benign tumour of the nail matrix but originates rarely from the ventral portion of the proximal nail fold. This tumour is characterised by fingerlike projections that invade the nail plate. This lesion, of unknown aetiology, is typically asymptomatic with slow progression. Localisation on the finger is the most frequently described. We report the case of a 68-year-old woman who has an onychomatricoma in an unusual location, the fifth toe of the left foot. Due to its clinical appearance, the tumour can be confused with and treated as onychomycosis. However, if it is resistant to an oral antifungal well behaved treatment, one must consider onychomatricoma diagnosis.
甲母质瘤是一种罕见的甲母质良性肿瘤，但很少起源于近端甲襞的腹侧部分。该肿瘤的特征是呈指状突起侵入甲板。这种病因不明的病变通常无症状且进展缓慢。最常描述的发病部位是手指。我们报告了一例68岁女性，其甲母质瘤位于一个不寻常的部位，即左脚第五趾。由于其临床表现，该肿瘤可能会与甲癣混淆并按甲癣治疗。然而，如果它对口服抗真菌药物规范治疗有抵抗，就必须考虑甲母质瘤的诊断。
