Various causes of hallux valgus exist. However, mass-induced hallux valgus is a rare phenomenon. To the best of our knowledge, there has been 1 previous report on mass-induced hallux valgus in the English literature; however, that report described giant cell tumor of the extensor digitorum longus tendon sheath. We believe ours to be the first published case of osteochondroma of the second metatarsus-induced hallux valgus. A 19-year-old woman presented with pain and tenderness in the left hallux of 3 months' duration. After a diagnosis of bony mass with hallux valgus, an operative excision was performed through a dorsal approach on the first web space of the left foot. The histopathologic diagnosis was osteochondroma. One-year follow-up radiographs showed a decreased hallux valgus angle and intermetatarsal angle. Unilateral hallux valgus occurs in a mass area. After excision of the mass, hallux valgus angle and intermetatarsal angle decrease. The rotational deformity is not severe. There is little probability of discovering its etiology, but mass-like osteochondroma should be considered.
拇外翻存在多种病因。然而，肿块导致的拇外翻是一种罕见现象。据我们所知，英文文献中此前仅有1例关于肿块导致拇外翻的报道；不过，该报道描述的是趾长伸肌腱腱鞘巨细胞瘤。我们认为我们的病例是首例关于第二跖骨骨软骨瘤导致拇外翻的发表案例。一名19岁女性，左拇趾疼痛及压痛3个月。在诊断为伴有拇外翻的骨质肿块后，通过左脚第一蹼间隙的背侧入路进行了手术切除。组织病理学诊断为骨软骨瘤。一年的随访X线片显示拇外翻角和跖间角减小。单侧拇外翻发生在肿块区域。切除肿块后，拇外翻角和跖间角减小。旋转畸形不严重。发现其病因的可能性很小，但应考虑肿块样骨软骨瘤。
