Benign cystic peritoneal mesothelioma.

Abstract

The well defined but rare entity of benign cystic mesothelioma is reported. The aetiology of this neoplasm remains obscure. The presenting features make a precise preoperative diagnosis difficult; information provided by computed tomography and cytology may help. A firm diagnosis can only come from electron microscopic or immunohistochemical examination of the tumour. Diagnostic accuracy and diligent follow up are essential because, although the tumour is considered benign, it does tend towards local recurrence.

“…In addition to hematoxylin-eosin sections, immunohistochemical staining is useful in the differential diagnosis. [7,8] Among these, benign multicystic peritoneal mesothelioma is most likely to …”

Peritoneal cystic mesothelioma presenting as a cystic mass in the pelvis: a challenging differential diagnosis

“…Preoperative findings according to most scoring systems indicate a benign lesion. Some authors suggest fine-needle aspiration cytology as an additional diagnostic step 11,28 . Mesothelial cells, perhaps with the presence of a brush border, are expected.…”
