Benign cystic mesothelioma of the peritoneum: a case report and literature review.

Benign cystic mesothelioma of the peritoneum (BCM) is an uncommon lesion with some 130 cases reported since the first case described by Smith and Mennenmeyer in 1979. It is a rare intra abdominal tumor occurring predominantly in women of reproductive age. Due to the rarity of this tumor, similarity of patient presentation, and comparable features on imaging, the diagnosis of this pathology is difficult, and is based on histological findings. This tumor is known for local recurrence. It's agreed that surgery is the only effective treatment, but there are no evidence-based treatment strategies for BCM.
