Splinter hemorrhages are non-blanchable usually distal reddish-brown linear hemorrhages beneath the nails. Among a variety of etiologic factors reported, trauma is the most common cause. A 26-year-old Hispanic female presented with asymptomatic, extensive fingernail hemorrhages of two months duration. There was no history of physical trauma to the nails. Treatment with a topical antifungal medication for one month produced no improvement. The past medical history was noncontributory. Extensive laboratory testing revealed no underlying systemic disease. Three months after the initial presentation, 6 of 10 fingernails showed signs of resolution without treatment. We conclude that idiopathic atraumatic subungual splinter hemorrhages can occur in healthy individuals. Spontaneous resolution occurred in our patient.
甲下线状出血是指甲下通常位于远端的不可褪色的红棕色线状出血。在已报道的多种病因中，外伤是最常见的原因。一名26岁的西班牙裔女性出现了持续两个月的无症状广泛性指甲出血。没有指甲受到物理外伤的病史。外用抗真菌药物治疗一个月没有改善。既往病史无特殊。广泛的实验室检查未发现潜在的全身性疾病。初次就诊三个月后，10个指甲中有6个未经治疗显示出消退迹象。我们得出结论，特发性非创伤性甲下线状出血可发生在健康个体中。我们的患者出现了自发消退。
