Riga-Fede disease is well reported in dental literature but is relatively unknown to the general pediatric community. It can be confused with nonaccidental trauma (NAT) from forced feeding or other abusive trauma because it presents with injury of oral structures including the sublingual frenulum and often results in problems with growth. This case highlights the importance for physicians to recognize RFD as a source of isolated oral injury that is distinct from NAT. Although approximately 35 cases of RFD have been reported in the literature, this is the first case to describe the process of distinguishing this disease from child abuse.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n We present a case of an 8-month-old female infant who presented with extensive injury of her ventral tongue from RFD who underwent a full workup for NAT. We review the literature for guidance on diagnosing RFD and discuss how to distinguish it from abuse.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Infants with characteristic ulceration of the ventral tongue opposing new teeth and with no other medical, social, or developmental concerns do not need to undergo further workup. Clinical examination and thorough history are sufficient to make the diagnosis.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Traumatic intraoral injury in nonmobile children is highly concerning for child abuse. However, RFD is a well described cause of sublingual ulceration in infants that is not associated with abuse.<\/jats:p>\n <\/jats:sec>","DOI":"10.1097\/pec.0000000000001922","type":"journal-article","created":{"date-parts":[[2019,11,12]],"date-time":"2019-11-12T10:08:39Z","timestamp":1573553319000},"page":"e1735-e1737","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":7,"title":["Riga-Fede Disease"],"prefix":"10.1097","volume":"37","author":[{"given":"Jonathan J.","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Division of Hospital Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maithri","family":"Sarangam","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Division of Hospital Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenneth W.","family":"Feldman","sequence":"additional","affiliation":[{"name":"Children's Protection Program, Seattle Children's Hospital, University of Washington, Seattle, WA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joel S.","family":"Tieder","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Division of Hospital Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","published-online":{"date-parts":[[2019,11,12]]},"reference":[{"key":"bib1-20250504","doi-asserted-by":"crossref","first-page":"195","DOI":"10.1016\/S0022-3476(44)80125-1","article-title":"Sublingual granuloma in infancy (Riga-Fede's disease): report of two cases","volume":"24","year":"1944","journal-title":"J Pediatr"},{"key":"bib2-20250504","doi-asserted-by":"crossref","first-page":"186","DOI":"10.1111\/j.1365-2230.2008.02796.x","article-title":"Traumatic lingual ulcer in a child: Riga-Fede disease","volume":"34","year":"2009","journal-title":"Clin Exp Dermatol"},{"key":"bib3-20250504","doi-asserted-by":"crossref","first-page":"285","DOI":"10.1111\/ced.12728","article-title":"Riga-Fede disease in a child","volume":"41","year":"2016","journal-title":"Clin Exp Dermatol"},{"key":"bib4-20250504","first-page":"142","article-title":"Lingual traumatic ulceration (Riga-Fede disease): report of a case and review","volume":"2","year":"2013","journal-title":"J Den Mater Tech"},{"key":"bib5-20250504","doi-asserted-by":"crossref","first-page":"209","DOI":"10.17796\/jcpd.25.3.9725k31q263800km","article-title":"Riga-Fede disease: report of a case and review","volume":"25","year":"2001","journal-title":"J Clin Pediatr Dent"},{"key":"bib6-20250504","doi-asserted-by":"crossref","first-page":"442","DOI":"10.1046\/j.1365-263X.2002.00396.x","article-title":"Riga-Fede disease: association with microcephaly","volume":"12","year":"2002","journal-title":"Int J Paediatr Dent"},{"key":"bib7-20250504","doi-asserted-by":"crossref","first-page":"283","DOI":"10.1186\/1752-1947-8-283","article-title":"Persistent lingual ulceration (Riga-Fede disease) in an infant with Down syndrome and natal teeth: a case report","volume":"8","year":"2014","journal-title":"J Med Case Reports"},{"key":"bib8-20250504","doi-asserted-by":"crossref","first-page":"581","DOI":"10.1097\/PEC.0000000000000286","article-title":"A perplexing case of child abuse: oral injuries in abuse and physician reporting responsibilities","volume":"31","year":"2015","journal-title":"Pediatr Emerg Care"},{"key":"bib9-20250504","doi-asserted-by":"crossref","first-page":"747","DOI":"10.1136\/archdischild-2017-313400","article-title":"Ex SI.
