We present a case of a retained toothpick causing pseudotumor of the first metatarsal in a young female who was referred as a case of painless swelling in the dorsolateral aspect of the right foot to exclude a malignant tumor. Plain radiograph did show an osteolytic lesion in the head and neck of the first metatarsal. Magnetic resonance imaging revealed a toothpick inside the first metatarsal head. Surgical exploration revealed a 4 cm toothpick embedded inside the bone surrounded by granulation tissue. We could find seven cases of retained foreign bodies causing osteolytic lesions in the metatarsals of the foot with one case of osteomylitis in an adult due to a retained small piece of toothpick. Retained foreign body should be considered in the differential diagnosis of an osteolytic lesion of the foot.
我们报告一例年轻女性因一枚残留牙签导致第一跖骨假瘤的病例。该患者因右足背外侧无痛性肿胀前来就诊，以排除恶性肿瘤。X线平片确实显示第一跖骨头和颈部有溶骨性病变。磁共振成像显示第一跖骨头内有一根牙签。手术探查发现一枚4厘米长的牙签嵌入骨内，周围有肉芽组织。我们发现有7例残留异物导致足部跖骨溶骨性病变的病例，其中1例为成人因残留一小片牙签引发骨髓炎。足部溶骨性病变的鉴别诊断应考虑残留异物。
