[Rare esophageal tumors of mesenchymal origen].

We present a 77-year-old male, smoker of 50 packs/year, with chronic obstructive pulmonary disease (COPD) and atrial fibrillation. He was admitted to the emergency because of progressive dysphagia for solids of three months duration and, in the last month, with liquid weight loss and anorexia. Endoscopy detected an exophytic neoformation in the middle third of the esophagus causing six centimeters partial stenosis of the lumen. The scan showed an esophageal tumor without local or distant spread. Bronchoscopy was negative for malignancy, thus ruling invasion of the respiratory tree. The microscopic study showed a mesenchymal spindle cell proliferation arranged in bundles, with increased vascularity and high mitotic index with abundant necrosis (Fig. 1 A and B). Fig. 1. A. Mesenchymal cells with atypical mitosis and necrosis forming multiple beams stained with hematoxylin and eosin. B. Shows more than one nucleolus indicating loss of normal architecture. A
