Esophageal metastasis from breast carcinoma associated with pseudoepitheliomatous hyperplasia: An unusual endoscopic diagnosis

The clinicopathologic findings in a patient who developed dysphagia and obstruction of the middle third of the esophagus 12 years after mastectomy for breast carcinoma are presented. Endoscopic biopsy revealed metastatic breast carcinoma with pseudoepitheliomatous hyperplasia of the overlying esophageal mucosa.
