Calcifying fibrous pseudotumor of the anterior parietal peritoneum: Treatment by laparoscopic resection*1

Abstract

A 37-year-old man had a computed tomography scan of the abdomen performed as part of a workup for blunt torso trauma. A 3-cm calcified mass was incidentally noted in the left upper quadrant of the anterior abdominal wall juxtaposing the anterolateral body of the stomach (Fig 1). The patient underwent laparoscopic excision of the mass (Fig 2, A, B) and was discharged home the same day. At the 1-month follow-up, the patient was doing well and reported no complaints. Histopathologic analysis revealed a densely localized, well-demarcated collagenous nodule with irregular and psammomatous calcifications, scattered chronic inflammatory cells (Fig 2, C), and heterotopic neo-ossification (Fig 2, D) characteristic of a calcifying fibrous pseudotumor.
