Esophagus leiomyoma with abnormal epidemiological characteristics: case report

Abstract

Introduction: Despite its rarity, the leiomyoma of the esophagus is the most common non-epithelial benign tumor in this organ. Case Report: The case of a 73-year-old woman diagnosed, initially, with esophageal mass to be clarified, oligosynthetics, was reported. A thorax CT scan revealed the presence of a tumor in the posterior mediastinum, coming from the proximal wall of the esophagus with extraluminal growth. A high digestive endoscopy and a biopsy of the lesion were performed, but turned out to be inconclusive. We chose surgical management through a right thoracotomy, with the esophageal tumor enucleated and the esophageal wall reconstructed. The pathology and immunohistokymic confirmed the diagnosis of a esophagealleiomyoma. Conclusion: The case has atypical epidemiological characteristics, such as the age group, the gender and location of the leiomyoma of the esophagus. Moreover, the literature review emphasizes the rarity of this pathology, which is usually an incidental finding in imaging or endoscopic exams, being quite a challenge not only diagnostically, but also therapeutically.
