Onychomatricoma is a rare, fibroepithelial tumor of the nail. Although it is benign, unnecessary and excessive treatment, such as extensive or total removal of the nail matrix, has been reported in the past. Recently, it was speculated that onychomatricoma is derived from onychomatricodermis, the dermal stroma of the nail matrix. Excision of the stromal rather than the epithelial component of the tumor is important. However, since the boundary between the normal and diseased stroma is usually unclear, minimal excision at the base of the tumor projection should be sufficient. We report a case of onychomatricoma and suggest a method of surgical treatment that would minimize postoperative deformity of the nail plate.
甲床纤维上皮瘤是一种罕见的甲部纤维上皮性肿瘤。虽然其为良性肿瘤，但既往曾有报道称对其行过度治疗，如广泛或全部切除甲母质。最近，有观点认为甲床纤维上皮瘤起源于甲母质真皮基质，即甲床的真皮基质。肿瘤的基质成分而非上皮成分的切除是重要的。然而，由于正常和病变的基质之间的边界通常不清晰，所以在肿瘤隆起的底部进行最小程度的切除应该就足够了。我们报告一例甲床纤维上皮瘤病例，并提出一种可将术后甲板畸形最小化的手术治疗方法。
