One month after initiating the new medication, he developed severe symptomatology with odynophagia and a very painful tongue. The physical examination reveals multiple erythematous patches on his tongue and a biopsy was performed. It allowed the diagnosis of benign migratory glossitis or geographic tongue. The patient was kept on tenofovir, but had to start topical corticoid therapy. Geographic tongue is a common condition that may be caused by drug idiosyncrasy, but has never before been associated to tenofovir. It is usually asymptomatic, but sometimes it causes severe symptoms, being an important impairment of quality of life.<\/jats:p>","DOI":"10.1136\/bcr-2013-008774","type":"journal-article","created":{"date-parts":[[2013,4,17]],"date-time":"2013-04-17T23:53:45Z","timestamp":1366242825000},"page":"bcr2013008774","source":"Crossref","is-referenced-by-count":8,"title":["Geographic tongue and tenofovir"],"prefix":"10.1136","volume":"2013","author":[{"given":"Alexandre Oliveira","family":"Ferreira","sequence":"first","affiliation":[{"name":"Department of Gastroenterology and Hepatology, Medical School of Lisbon, Hospital Santa Maria, Lisbon, Portugal"}]},{"given":"Rui Tato","family":"Marinho","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology and Hepatology, Medical School of Lisbon, Hospital Santa Maria, Lisbon, Portugal"}]},{"given":"Jos\u00e9","family":"Velosa","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology and Hepatology, Medical School of Lisbon, Hospital Santa Maria, Lisbon, Portugal"}]},{"given":"Jo\u00e3o Borges","family":"Costa","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Hospital Santa Maria, Lisbon, Portugal"}]}],"member":"239","published-online":{"date-parts":[[2013,4,17]]},"reference":[{"key":"2025082801323536000_2013.apr17_1.bcr2013008774.1","doi-asserted-by":"crossref","first-page":"751","DOI":"10.1016\/S0002-9343(02)01379-7","article-title":"Benign migratory glossitis or geographic tongue: an enigmatic oral lesion","volume":"2013","author":"Assimakopoulos","year":"2002","journal-title":"Am J Med"},{"key":"2025082801323536000_2013.apr17_1.bcr2013008774.2","doi-asserted-by":"crossref","first-page":"e44","DOI":"10.1056\/NEJMicm0810145","article-title":"Images in clinical medicine.
