ABSTRACT

Calcifying fibrous pseudotumor is a rare, benign, hypocellular tumor-like lesion that is characterized by the presence of dense hyalinized collagenous tissue interspersed with small spindle cells, dystrophic calcifications, or psammomatous and variable lymphoplasmacytic infiltrations. We report the case of a 37-year-old woman with a posterior mediastinal mass, in close contact with the distal third of the esophagus, treated by complete resection through a laparoscopic approach. The tumor had the histologic and immunohistochemical features of a calcifying fibrous pseudotumor.

Key Words: Calcifying fibrous pseudotumor, lower posterior mediastinum, laparoscopy, resection
