Challenges of Benign Multicystic Mesothelioma: Recurrence and Metastasis- A Rare Case Report

A rare condition called multicystic mesothelioma, also known as benign multicystic peritoneal mesothelioma (BMCM), originates from parietal or visceral peritoneum mostly affecting females of reproductive age, often challenging to diagnose accurately prior surgery. We present a 28-yearold woman with a image guided core biopsy proven mucinous ovarian adenocarcinoma who underwent definitive surgery, her biopsy surprisingly revealed benign multicystic mesothelioma. Since multicystic mesothelioma can behave like locally malignant tumors despite its benign origin, an accurate diagnosis is crucial to formulate appropriate management plan. This case report highlights the need for awareness of multicystic mesothelioma due to its rarity, diagnostic complexity, and potential for recurrence despite its generally benign behavior. Further research is warranted to elucidate the pathogenesis, optimize treatment strategies, and improve patient outcomes. Comprehensive diagnostic and surgical strategy play a crucial role in this regard.
