CROVETTO MARTINEZ, R.; WHYTE OROZCO, J.; CISNEROS, A.I.  e  CROVETTO DE LA TORRE, M.A.. Cocaine-induced midline destructive lesion and oronasal fistula. Av Odontoestomatol [online]. 2014, vol.30, n.2, pp.63-67. ISSN 2340-3152.

The authors perform a literature review of palatal fistulas present in midline necrotizing nasal lesions due to inhalation of cocaine and present a case report. The frequency of palatal fistulas associated with midline necrotizing lesions by inhalation of cocaine is superior to tose found in Wegener's granulomatosis. The presence of a palatal fistula is also suggestive of a extranodal lymphoma. Histopathology is the key to the differential diagnosis but getting an unequivocal diagnosis is more difficult to obtain than might be supposed.

Palavras-chave : Midline necrotizing nasal lesions; cocaine; palatal fistula.
