A 32-yr-old man was admitted to Anjo Kosei Hospital for the examination of a cystic peritoneal lesion. This patient had a past medical history significant for an appendectomy. Ultrasonography and computed tomography revealed multiple cysts in the abdominal and pelvic cavities. An exploratory laparotomy was performed on July 1, 1993, revealing numerous thin-walled and translucent cysts in the serosal tissues of the parietal and visceral abdominal peritoneum. These cysts were excised surgically because of clinical suspicion of pseudo-myxoma peritonei. Microscopic examination revealed cysts within the thin cyst wall that were composed of fibrous connective tissue and lined by a single layer of cuboidal or flattened epithelium. Immunohistochemical and ultrastructural studies demonstrated that the lining cells were of mesothelial origin, and the diagnosis was benign cystic mesothelioma. In this paper, we present appropriate diagnostic and treatment procedures for benign cystic mesothelioma and discuss the particular usefulness of using immunohistochemical methods to achieve a histological diagnosis.
一名32岁男性因检查囊性腹膜病变入住安城光生医院。该患者既往有阑尾切除术史。超声检查和计算机断层扫描显示腹腔和盆腔内有多个囊肿。1993年7月1日进行了剖腹探查术，发现腹前壁和脏腹膜浆膜组织中有许多薄壁半透明囊肿。由于临床怀疑为腹膜假黏液瘤，这些囊肿被手术切除。显微镜检查显示薄囊壁内的囊肿由纤维结缔组织构成，内衬单层立方上皮或扁平上皮。免疫组织化学和超微结构研究表明内衬细胞起源于间皮，诊断为良性囊性间皮瘤。在本文中，我们介绍了良性囊性间皮瘤的适当诊断和治疗方法，并讨论了使用免疫组织化学方法进行组织学诊断的特殊用途。
