Vet. Sci."],"abstract":"<jats:p>An 11-year-old, intact female Pomeranian dog was presented for evaluation due to an 18-h history of anorexia and lethargy. Abdominal ultrasound revealed a 3\u00d73 cm mass of mixed echogenicity at the level of the left ovary. At laparotomy, a 5\u2009mm mass was identified at the cranial region of the right uterine horn and a 3\u2009cm round mass was visualized near the cranial aspect of the left uterine horn. Ovariohysterectomy was performed. A diagnosis of grade 1 oviductal and uterine leiomyosarcoma was made via histopathology for both masses. Oviductal leiomyosarcomas are rare and generally locally invasive similar to other soft tissue sarcomas but do not often metastasize. Uterine leiomyosarcomas are also uncommon but are one of the more common tumors affecting the female reproductive tract. This is the only known case report of oviductal leiomyosarcoma in the dog and the only report of uterine leiomyosarcoma in addition to oviductal leiomyosarcoma as well. This case illustrates the oviduct as an additional site that can be affected by leiomyosarcoma and demonstrates surgery as a treatment option for patients diagnosed with this condition.<\/jats:p>","DOI":"10.3389\/fvets.2023.1227799","type":"journal-article","created":{"date-parts":[[2023,12,7]],"date-time":"2023-12-07T12:13:09Z","timestamp":1701951189000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Case report: A case of oviductal and uterine leiomyosarcoma in an 11-year-old dog"],"prefix":"10.3389","volume":"10","author":[{"given":"Jillian","family":"Kazmierczak","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicole J.","family":"Sugai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katie E.","family":"Withowski","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abe","family":"Jonatan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tanya","family":"LeRoith","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julie T.","family":"Cecere","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2023,12,7]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"597","DOI":"10.1016\/B978-0-323-59496-7.00027-X","article-title":"Tumors of the female reproductive system","volume-title":"Withrow and MacEwen\u2019s small animal clinical oncology","author":"Saba","year":"2019"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"515","DOI":"10.1177\/104063870301500602","article-title":"Uterine neoplasia in 13 cats","volume":"15","author":"Miller","year":"2003","journal-title":"J Vet Diagn Investig"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"552","DOI":"10.1354\/vp.43-4-552","article-title":"Uterine myxoid leiomyosarcoma with widespread metastases in a cat","volume":"43","author":"Cooper","year":"2006","journal-title":"Vet Pathol"},{"key":"ref4","doi-asserted-by":"publisher","first-page":"2382","DOI":"10.3382\/ps.0702382","article-title":"Research note: lack of an effect of high levels of menadione on tumor development in Japanese quail females","volume":"70","author":"Nestor","year":"1991","journal-title":"Poult Sci"},{"key":"ref5","first-page":"268","article-title":"Smooth muscle neoplasia of suspected oviductal origin in the cloaca of a blue-fronted Amazon parrot (Amazona aestiva)","volume":"11","author":"Antinoff","year":"1997","journal-title":"J Avian Med Surg"},{"key":"ref6","doi-asserted-by":"publisher","first-page":"456","DOI":"10.1016\/j.tjog.2018.04.024","article-title":"Primary leiomyosarcoma of the fallopian tube: three case reports and review of the literature","volume":"57","author":"Xia","year":"2018","journal-title":"Taiwan J Obstet Gynecol"},{"key":"ref7","first-page":"1096","article-title":"Leiomyosarcoma of the fallopian tube in a young patient","volume":"5","author":"Orsaria","year":"2018","journal-title":"Austin J Obst Gynecol"},{"key":"ref8","first-page":"445","article-title":"Tumors of the female reproductive system","volume-title":"Small animal clinical oncology","author":"Withrow","year":"2001"},{"key":"ref9","first-page":"97","article-title":"Tumors of the urogenital system in dogs and cats.
