Benign multicystic mesothelioma of peritoneum : a clinico-pathological study of four cases

Abstract EN

Objective : to study the clinico-pathological findings of benign multicystic mesothelioma, also known as multicystic peritoneal inclusion cyst (MPIC) which is a rare disease of mesothelial origin.

Methods & materials : the clinical medical records and the pathology reports of four patients diagnosed as having benign multicystic mesothelioma at Bahrain Defence Force Hospital during one year period between 2003-2004 were evaluated.

The H&E stained slides along with the special histochemistry stains and immunoperoxidase techniques were applied for confirmation of the diagnosis.

Results : all cases in our study occurred in females aged of 28-46 years with the mean 39.

Two patients had previous surgery.

The chief complaints included abnormal uterine bleeding, abdominal or pelvic pain and dyspareunia.

The size of the cysts ranged 2-3.

2 cm in diameter.

The histology showed multilocular cystic spaces lined by mesothelial cells which were confirmed by application of special stains and immunoperoxidase techniques.

Conculsion : benign muticystic mesothelioma / MPIC should be distinguished from other benign and malignant tumours as it has excellent prognosis if completely excised.

Proper utilization of diagnostic facilities is essential for accurate diagnosis.
