We present a unique case of papillary mesothelioma of the pelvic peritoneum with extensive myxoid change in a 44-year-old woman. The patient presented with lower abdominal pain; imaging studies revealed a pelvic mass. Microscopic examination of the surgically resected specimen showed extensive areas of myxoid stroma and only focal areas of classical papillary mesothelioma. A small biopsy of this lesion might have been misinterpreted as a soft tissue neoplasm with myxoid stroma or pseudomyxoma peritonei. It is suggested that mesothelioma with myxoid change should be included with differential diagnoses of myxoid lesions of the peritoneum.
我们报告了一例44岁女性盆腔腹膜乳头状间皮瘤伴广泛黏液样改变的独特病例。患者表现为下腹部疼痛；影像学检查发现盆腔有肿块。对手术切除标本的显微镜检查显示有广泛的黏液样基质区域，仅局灶性区域为经典的乳头状间皮瘤。对该病变进行的小活检可能会被误诊为伴有黏液样基质的软组织肿瘤或腹膜假黏液瘤。建议将伴有黏液样改变的间皮瘤纳入腹膜黏液样病变的鉴别诊断中。
