    • "Tumor recurrence was reported in half of the patients even complete cytoreduction was achieved [1] [12]. Therefore, routine followup with imaging techniques is required in patients after operation [13]. Our patient was ended up with a recurrence of BMPM 15 years later following her first operation suggesting long term followup is necessary in patients with BMPM. "

    ABSTRACT: Benign multicystic peritoneal mesothelioma (BMPM) is a rare disease arising from the peritoneal mesothelium. Here, we report a 57-year-old woman admitted to our unit with an incisional hernia fifteen years later following her first operation due to BMPM. Computerized tomography demonstrated a cystic appearing mass with intraabdominal extension in hernia sac. The patient underwent en bloc resection of the mass and hernia repair. An immunohistochemical analysis of the mass confirmed the recurrence of BMPM. Our case supports that BMPM has slowly progressive nature and can recur with complicated incisional hernia long time after primary resection. Diagnosis and long-term followup are crucial for clarifying the characteristics of this disease.

    • "Patients usually complain of abdominal pain, anorexia, vague abdominal distress or palpable abdominal mass [5]. Less frequently it may be found incidentally on routine physical or imaging examinations without any symptoms, as in our case [9]. "

    ABSTRACT: Cystic mesotheliomas are benign neoplasms, often seen in the parietal and visceral peritoneum, omentum and pelvic organs, and are exceedingly rare in the liver. It is however important to be familiar with the radiological findings of this tumour because the signal-intensity and enhancement pattern of this tumor are unusual and not typical for any of the more frequently seen mass lesions. In our patient, characteristic imaging findings on dynamic contrast-enhanced MRI and histopathological confirmation with appropriate immunohistochemical markers facilitated a correct diagnosis. We herein describe the clinical, imaging and histopathological features, pathogenesis, differential diagnosis and treatment of benign cystic mesothelioma involving posterior segment of the right lobe of the liver.

    ABSTRACT: The report presents six cases of mesothelial inclusion cysts (MIC), detected in five females (22-53 years of age) and one male (47 years old). The lesions were unifocal (four cases) and multifocal (two cases), and were located on the surface of the peritoneum in the cul de sac, on the intestines, urinary bladder, uterine adnexa, also involved round ligament within the pelvis and in the inguinal canal (one patient). Additionally, in one female, small cysts, free-floating in the peritoneal cavity were present. In three patients, clinical signs resulted directly from the presence of MIC. One female had been 7 years previously operated on due to endometrioid ovarian cysts. Apart from MIC, three patients presented with concomitant diseases: appendicitis (two cases), peritoneal pseudomyxoma or primary ovarian carcinoma. Gross appearance: the lesions were polycystic, the surgical materials ranging from three fragments measuring 0.5 cm each to seven fragments, with the maximum size of 14x6 cm. The cysts were from microscopic size to 2 cm in diameter, the majority were thin-walled, semitranslucent, filled with clear or yellowish fluid or gelatinous contents. In one case, the cyst walls were thicker and showed intense inflammatory lesions and fibrinous exudate. Microscopically, the majority of cysts were lined with a single layer of flattened or cuboid mesothelial cells (CK+, calretinin+). In two patients, the mesothelium demonstrated diffuse squamous cell metaplasia; in one individual, the cells focally formed small papillae and were vacuolated. No mucus was observed either in the cytoplasm or outside the cells. Immunohistochemical reactions to CEA, ER, PR and MIB-1 were negative. Intramural proliferations and intracystic detached clumps of cells showed both mesothelial cells (without any mitotic activity and signs of atypia) and macrophages (CD68+). To date, the follow-up has been 7 years and 3 years in two individuals, and from 1 to 7 months in the remaining three patients--all of them are free from recurrent disease. One female failed to report for follow-up examinations. The report also presents the review of literature.
