Abstract
BackgroundLeiomyomas of esophagus, although rare, are the most frequent benign tumors of esophagus. Aim of this study is the presentation of 7 patients with esophageal leiomyomas who underwent surgical treatment during a 9-year period.MethodsEpidemiological data (sex, age), the presenting symptoms, diagnostic examinations, tumor location, histopathological findings and the safety and efficacy of surgical resection are analyzed and assessed.Results5 men and 2 women with mean age of 56.9 years were operated. In 3 cases the tumor was located at the lower esophagus, while in the other 4 cases, the leiomyoma was found at the median third of esophagus. 4 patients had severe symptoms related to the leiomyoma, such as dysphagia and epigastric pain. All patients underwent a right postolateral thoracotomy with enucleation of the lesion. None of them received resection of part of the esophagus. The mean diameter of the resected tumors was 4.3 cm. The dimensions of leiomyomas were immediately associated with the symptoms. In no case was detected malignancy or recurrence. All patients were relieved from their symptoms, while postoperative morbidity and mortality did not occur.ConclusionsEsophageal leiomyoma is a benign tumor, which causes symptoms only if its size becomes large. Surgical enucleation is considered to be safe and effective, without complications.

Summary
Leiomyomas of esophagus, rare, are the most frequent benign tumors of esophagus. Aim of this study is the presentation of 7 patients with esophageal leiomyomas who underwent surgical treatment during a 9-year period. The esophageal leiomyoma is a benign tumor of the esophagus. Other non-malignant lesions of esophagus are hemangioma, lymphangioma, squamous papilloma, fibrovascular polyp and granular cell myoblastoma. The incidence of this kind of lesions is referred to be almost 1% of the esophageal neoplasms in the international literature [1]. Differential diagnosis should always include esophageal cancer [2]. It is important for the modern cardiothoracic surgeon to be aware of this entity.
