His symptoms initiated 20 years earlier with a pustule on his left ear, which evolved into an erythematous plaque that ulcerated and progressively destroyed the surrounding cartilage. Initial treatment of presumed cutaneous leishmaniasis was ineffective. Biopsies performed revealed chronic granulomatous dermatitis, and cultures on Sabouraud medium identified <jats:italic>Sporothrix<\/jats:italic> spp. Additionally, a sporotrichin intradermal test was performed, revealing a positive result. The patient achieved complete resolution after treatment with potassium iodide (6 g per day for 4 months). He declined reconstructive surgery. Infections by <jats:italic>Sporothrix<\/jats:italic> spp. can lead to lesions that can mimic other infectious or noninfectious causes such as cutaneous leishmaniasis. It is important to consider endemic mycosis even in unusual anatomical locations such as the auricle, especially when prior treatment has failed.<\/jats:p>","DOI":"10.4269\/ajtmh.25-0038","type":"journal-article","created":{"date-parts":[[2025,6,17]],"date-time":"2025-06-17T14:25:26Z","timestamp":1750170326000},"page":"701-703","source":"Crossref","is-referenced-by-count":0,"title":["Ear Sporotrichosis Mimicking Cutaneous Leishmaniasis"],"prefix":"10.4269","volume":"113","author":[{"given":"V\u00edctor M.","family":"Tarango-Mart\u00ednez","sequence":"first","affiliation":[{"name":"Department of Dermatology, Instituto Dermatol\u00f3gico de Jalisco \u201cDr. Jos\u00e9 Barba Rubio\u201d, Universidad de Guadalajara, Jalisco, Mexico;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arturo","family":"Robles-Tenorio","sequence":"additional","affiliation":[{"name":"Escuela de Medicina y Ciencias de la Salud, Tecnol\u00f3gico de Monterrey, Monterrey, Mexico;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jesus Alberto","family":"Cardenas-de la Garza","sequence":"additional","affiliation":[{"name":"Department of Rheumatology, Hospital Universitario \u201cDr. Jos\u00e9 Eleuterio Gonz\u00e1lez\u201d, Monterrey, Mexico;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lucio","family":"Vera-Cabrera","sequence":"additional","affiliation":[{"name":"Laboratorio Interdisciplinario de Investigaci\u00f3n Dermatol\u00f3gica, Servicio de Dermatolog\u00eda, Hospital Universitario, Monterrey, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2795","reference":[{"key":"b1","series-title":"Braz J Microbiol","first-page":"49","article-title":"Sporotrichosis in Mexico","volume":"52","author":"Toriello","year":"2021"},{"key":"b2","series-title":"JAMA Dermatol","first-page":"259","article-title":"Endemic human cutaneous leishmaniasis incidence in the United States","volume":"155","author":"Kipp","year":"2019"},{"key":"b3","series-title":"Rev Chil Infectol","first-page":"83","article-title":"Esporotricosis del pabell\u00f3n auricular.
