title: Unusual presentation of pulmonary inflammatory pseudotumor (plasma cell granuloma) as esophageal obstruction.
abstract: A 12-year old boy had a five-year course of dysphagia secondary to lower esophageal obstruction by a posterior mediastinal extension of an inflammatory pseudotumor of the lung. The case illustrates the capacity of pseudotumor to behave in a locally aggressive manner and to present in extrapulmonic sites.
