Mesotheliomas are benign masses that can arise from any body parts that contain mesothelium, such as the abdominal, pelvic, pleural, and pericardial cavities. Benign multicystic peritoneal mesothelioma is a cystic tumor that arises from peritoneal mesothelial cells. It is a rare pathological entity, as only fewer than 200 cases have been reported. Benign multicystic peritoneal mesothelioma mainly occurs in women, and it is extremely rare in men. Its diagnosis and management are often challenging.
This report demonstrates a case of a 61-year-old man who presented to the outpatient clinic with persistent abdominal discomfort that progressed over the years. He had visited different clinics and was referred to a gastroenterologist because of a misdiagnosis. After an extensive clinical evaluation, we failed to provide a definitive diagnosis; thus, diagnostic laparotomy for possible intra-abdominal malignancy was performed. After successful surgical resection of the lesions, the pathology was found compatible with benign multicystic peritoneal mesothelioma.
Given its high recurrence rates and potential malignant transformation, meticulous and detailed surgical excision of the cystic lesions is of utmost importance to avoid repeated surgeries. Long-term follow-up is recommended.
间皮瘤是一种良性肿块，可起源于任何含有间皮的身体部位，如腹腔、盆腔、胸腔和心包腔。良性多囊性腹膜间皮瘤是一种起源于腹膜间皮细胞的囊性肿瘤。它是一种罕见的病理实体，因为报告的病例少于200例。良性多囊性腹膜间皮瘤主要发生于女性，男性极为罕见。其诊断和治疗往往具有挑战性。
本报告展示了一例61岁男性病例，该患者多年来持续出现腹部不适，并到门诊就诊。他曾就诊于不同诊所，因误诊被转诊至胃肠病学家处。经过广泛的临床评估，我们未能做出明确诊断；因此，对可能的腹腔内恶性肿瘤进行了诊断性剖腹手术。成功手术切除病变后，病理结果显示与良性多囊性腹膜间皮瘤相符。
鉴于其高复发率和潜在的恶性转化，对囊性病变进行细致彻底的手术切除对于避免重复手术至关重要。建议进行长期随访。
