A case of cystic mesothelioma of the peritoneum, presenting as acute appendicitis is reported. The authors stress the difficulty of a correct preoperative diagnosis of this rare tumor, which however, may be considered benign, with a good long-term prognosis.

A case of peritoneal cystic mesothelioma in a 40-yr-old woman is reported. The patient was operated on for signs of acute appendicitis. The lesion was made up of small, multiple, thin-walled cysts and both visceral and parietal layers of the peritoneum in the appendix region were involved. The lesion must be differentiated from other cystic lesions of the abdominal cavity and in particular from the multilocular lymphangioma. The diagnostic role of special techniques, such as immunohistochemistry and electron microscopy, in difficult cases is emphasized.

An extremely rare case of mucinous cystadenoma developing to pseudomyxoma peritonei together with multicystic peritoneal mesothelioma is herein reported. The patient was 25-year-old Japanese woman who underwent an appendectomy under the diagnosis of acute appendicitis because of right lower abdominal pain. The patient histopathologically demonstrated appendiceal mucocele with pseudomyxoma peritonei. She underwent a laparotomy in our unit following detailed examinations. Several cystic tumors measuring from 3 to 5 cm in diameter were found in the omentum, and thus omentectomy, partial cecectomy and left oophorectomy were all performed to resect the tumors. Immunostaining and electron microscopy showed the appendiceal lesion to be mucinous cystadenoma, while the peritoneal lesion was multicystic mesothelioma. To our knowledge, this is the first report in the world literature of this rare combination of diseases.

The aim of this study is to report the experience of a case of benign multicystic mesothelioma of the peritoneum presented with acute appendicitis symptomatology. A 28 years old man with right lower and upper abdominal pain was admitted into hospital. Because of the clinical picture, the symptomatology and the leukocytosis a diagnosis of acute appendicitis was made and the patient underwent appendicectomy according to Mc Burney. At laparotomy some cc of purulent fluid were sucked and a cystic mass that contained clear fluid was revealed. In consequence of the incidental diagnosis a following middle laparotomy was made with a careful surgical excision of the mass and of the appendix. Macroscopically the lesion was identified like a neoplastic mass 25 centimeters in diameter, with a multicystic and fibrous-adipose aspect, with cysts 5 centimeters in diameter. The cystic spaces were lined by a layer of eptelial cells which presented positive reaction for cytokeratin and EMA, whereas endothelium markers were absent. The ultrastructural, morphological and immunohistochemical findings were diagnostic of a benign multicystic mesothelioma.
