Esophageal inflammatory pseudotumor mimicking malignancy

A 54-year-old man with a complaint of dysphagia was found to have a promine nt stricture in the proximal esophagus. A biopsy of the stenotic area indic ated sarcoma, leading to subtotal esophagectomy. The surgically removed eso phagus 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.
