Leiomyoma of the cervical esophagus: a case report.

Leiomyomas are the most common benign mesenchymal neoplasms of the esophagus and constitute 04-1.5% of all tumours of this organ. We present a case of a 53-year-old woman with a single, small leiomyoma located in the cervical esophagus. The lesion was asymptomatic and unexpectedly revealed during esophagoscopy. The endoscopic electroresection of the tumour was performed. The patient remains well seven months after resection. The microscopic examination found a well circumscribed tumour composed of interlacing bundles of spindle cells with elongated cigar-shaped nuclei without pleomorphism showing positive immunostaining for desmin and a-smooth muscle actin.
