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.<\/jats:p>\n          <jats:p>A 19-year-old woman presented with pain and tenderness in the left hallux of 3 months\u2019 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.<\/jats:p>\n          <jats:p>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.<\/jats:p>","DOI":"10.3928\/01477447-20101021-34","type":"journal-article","created":{"date-parts":[[2010,12,16]],"date-time":"2010-12-16T20:05:47Z","timestamp":1292529947000},"source":"Crossref","is-referenced-by-count":1,"title":["Mass-Induced Unilateral Hallux Valgus"],"prefix":"10.3928","volume":"33","author":[{"given":"Ki Won","family":"Young","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kyung Tai","family":"Lee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeong Ja","family":"Kwak","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Young Koo","family":"Lee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Young Uk","family":"Park","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2308","reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.3113\/FAI.2008.0534"},{"key":"e_1_3_1_3_2","doi-asserted-by":"publisher","DOI":"10.3113\/FAI.2007.0759"},{"key":"e_1_3_1_4_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-195840050-00007"},{"key":"e_1_3_1_5_2","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.62B2.7364833"},{"key":"e_1_3_1_6_2","doi-asserted-by":"publisher","DOI":"10.1177\/107110070102201007"},{"key":"e_1_3_1_7_2","doi-asserted-by":"publisher","DOI":"10.1177\/107110070102200203"},{"key":"e_1_3_1_8_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199606000-00018"},{"key":"e_1_3_1_9_2","doi-asserted-by":"publisher","DOI":"10.1177\/107110070002101004"},{"key":"e_1_3_1_10_2","first-page":"150","volume-title":"Surgery of the Foot and Ankle","author":"Mann RA","year":"1999","unstructured":"Mann RA, Coughlin MJ.
