Esophageal perforation (EP) is a medical condition which demands urgent confrontation with significant complications. The cause of the perforation may be common, spontaneous or iatrogenic, with conservative or surgical therapeutic strategy, which is needed in the majority of incidents, depending on the characteristics of the lesion. We report a case of a 68-year-old man, with the existence of an ulcerative lesion 31 cm approximately from the dental barrier, and a coexistent stenosis, diagnosed through esophagogastroduodenoscopy, which evolved to an extensive purulent necrotic mediastinitis, diagnosed through a thorax CT scan after the patient began to complain of asphyxiation during eating. A right posterolateral thoracotomy was performed along with intensive wide spectrum antibiotic therapy. Primary closure of the perforation as well as pulmonary tenting was used with satisfactory results. There was no evidence of leakage after a 12-month "follow-up" period. The early diagnosis of an EP combined with immediate surgical procedure and frequent "follow-up" of the patient, eliminate the risks for the patient's life and ensure a satisfactory outcome.
