title: Esophageal inflammatory pseudotumor mimicking malignancy.
abstract: A 54-year-old man with a complaint of dysphagia was found to have a prominent stricture in the proximal esophagus. A biopsy of the stenotic area indicated sarcoma, leading to subtotal esophagectomy. The surgically removed esophagus demonstrated a well-defined intramural mass, consisting of a mixture of fibroblastic cells with bland cytological appearances and inflammatory cells. Reflux esophagitis which was present distal to the stricture seemed to play a role in the development of this inflammatory pseudotumor.
