These tumors can behave as malignant neoplasms clinically and pathologically and can metastasize occasionally. No cases of MLTB in rodents have been reported, to our knowledge. We describe a novel case of an MLTB in a guinea pig. An adult guinea pig had an exophytic mass fixed on the frontal bone, maxilla, and nasal bone. On radiography, the mass had a spherical contour and variable density and was formed on the surface of the cranial bones. The mass was excised surgically. The cut surface was light-yellow to milky-white and had a granular texture with fine fibrous septa. Histologically, the neoplasm had a multilobular pattern, which consisted of many islands of bone and\/or cartilage matrix surrounded by small cells and separated by fibrous septa, which closely resembles the equivalent neoplasm in dogs.<\/jats:p>","DOI":"10.1177\/1040638720941507","type":"journal-article","created":{"date-parts":[[2020,7,18]],"date-time":"2020-07-18T04:05:33Z","timestamp":1595045133000},"page":"747-749","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Multilobular tumor of bone on the forehead of a guinea pig"],"prefix":"10.1177","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9063-7616","authenticated-orcid":false,"given":"Hitoshi","family":"Hatai","sequence":"first","affiliation":[{"name":"Department of Pathogenetic and Preventive Veterinary Science, Joint Faculty of Veterinary Medicine, Kagoshima University, Kagoshima, Japan (Hatai)"},{"name":"Kanazawa Zoological Gardens, Yokohama Greenery Foundation, Yokohama, Kanagawa, Japan (Kido)"},{"name":"Laboratory of Veterinary Pathology, Faculty of Agriculture, Iwate University, Morioka, Iwate, Japan (Ochiai)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7285-3457","authenticated-orcid":false,"given":"Nobuhide","family":"Kido","sequence":"additional","affiliation":[{"name":"Department of Pathogenetic and Preventive Veterinary Science, Joint Faculty of Veterinary Medicine, Kagoshima University, Kagoshima, Japan (Hatai)"},{"name":"Kanazawa Zoological Gardens, Yokohama Greenery Foundation, Yokohama, Kanagawa, Japan (Kido)"},{"name":"Laboratory of Veterinary Pathology, Faculty of Agriculture, Iwate University, Morioka, Iwate, Japan (Ochiai)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenji","family":"Ochiai","sequence":"additional","affiliation":[{"name":"Department of Pathogenetic and Preventive Veterinary Science, Joint Faculty of Veterinary Medicine, Kagoshima University, Kagoshima, Japan (Hatai)"},{"name":"Kanazawa Zoological Gardens, Yokohama Greenery Foundation, Yokohama, Kanagawa, Japan (Kido)"},{"name":"Laboratory of Veterinary Pathology, Faculty of Agriculture, Iwate University, Morioka, Iwate, Japan (Ochiai)"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2020,7,18]]},"reference":[{"key":"bibr1-1040638720941507","doi-asserted-by":"publisher","DOI":"10.1111\/j.1751-0813.2004.tb11127.x"},{"key":"bibr2-1040638720941507","doi-asserted-by":"publisher","DOI":"10.1002\/9781118924051.ch05"},{"key":"bibr3-1040638720941507","doi-asserted-by":"publisher","DOI":"10.2460\/javma.244.6.651"},{"key":"bibr4-1040638720941507","doi-asserted-by":"publisher","DOI":"10.5326\/15473317-34-1-11"},{"key":"bibr5-1040638720941507","doi-asserted-by":"publisher","DOI":"10.1177\/089875641002700304"},{"key":"bibr6-1040638720941507","doi-asserted-by":"publisher","DOI":"10.1111\/j.1740-8261.2000.tb01480.x"},{"key":"bibr7-1040638720941507","doi-asserted-by":"publisher","DOI":"10.1111\/j.1748-5827.1994.tb03845.x"},{"key":"bibr8-1040638720941507","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9975(84)90068-9"},{"key":"bibr9-1040638720941507","doi-asserted-by":"publisher","DOI":"10.1638\/2012-0068R.1"},{"key":"bibr10-1040638720941507","first-page":"804","volume":"186","author":"Morton D.","year":"1985","journal-title":"J Am Vet Med Assoc"},{"key":"bibr11-1040638720941507","doi-asserted-by":"publisher","DOI":"10.4142\/jvs.2006.7.3.297"},{"key":"bibr12-1040638720941507","doi-asserted-by":"publisher","DOI":"10.4142\/jvs.2009.10.1.81"},{"key":"bibr13-1040638720941507","first-page":"289","volume":"182","author":"Richardson DW","year":"1983","journal-title":"J Am Vet Med Assoc"},{"key":"bibr14-1040638720941507","doi-asserted-by":"publisher","DOI":"10.1016\/j.jfms.2006.12.006"},{"key":"bibr15-1040638720941507","first-page":"1764","volume":"195","author":"Straw RC","year":"1989","journal-title":"J Am Vet Med Assoc"},{"key":"bibr16-1040638720941507","doi-asserted-by":"crossref","unstructured":"Thompson KG, Dittmer K.
