Abstract
BACKGROUND Primary intrahepatic mesothelioma (PIHMM) has been rarely reported. Its typical clinical presentation, radiological features and pathology have not been defined. Here, we aimed to summarize its diagnosis and treatment. METHODS We conducted a retrospective analysis of three cases of PIHMM in the First Affiliated Hospital of Zhejiang University School of Medicine and reviewed the current literature to investigate the clinical and pathological characteristics and prognosis of PIHMM. RESULTS Based on our case series and the literature, the mean age of PIHMM was 59.7 (41-83) years. Most patients present with nonspecific symptoms such as abdominal pain, fever, weight loss and weakness. On imaging, PIHMM usually presented as a solid, heterogeneous soft tissue mass with irregular margins and significant enhancement of the margins in the arterial phase. Immunohistochemical markers such as calretinin, cytokeratin (CK)5/6, D2-40, WT-1, mesothelin CK and vimentin may be useful for diagnosis. The 3-year relapse-free survival rate (RFS) was 51.85%, the 3-year overall survival (OS) rate was 83.33% and the 3-year postoperative overall survival rate was 100%. CONCLUSION PIHMM can only be diagnosed by careful postoperative pathology, because of its nonspecific clinical presentations, serological indicators or imaging features. Immunohistochemical staining is very useful to distinguish this tumor from other liver tumors. Surgery is the mainstay of treatment.

Abstract
Key Clinical Message Malignant peritoneal mesothelioma, a rare and poor prognosis disease, is seldom treated surgically, especially for recurrence. However, early diagnosis and aggressive treatment of primary and recurrent tumors can achieve long-term patient survival. Abstract Malignant peritoneal mesothelioma (MPM) is a rare and aggressive tumor, and rarely indicated for surgery, especially for recurrence. In the present case, we report a rare case who could survive long-term after two surgeries in 4 years for MPM.

Abstract
Localized malignant peritoneal mesothelioma is a rare tumor with limited information in the literature. In this study, we present our experience with 18 cases seen in our hospital over a period of 43 years (1978 to 2021). Patients' median age was 55 years (y) (range: 33 to 79 y) and most of them were Caucasians. Patients presented with abdominal pain (11), ascites and right leg swelling (1), abdominal mass (1), and as incidental finding (1). Thirty percent of patients reported asbestos exposure, and all patients with available information had family history of tumors; a third had personal history of tumors. Seventy-seven percent had some form of abdominopelvic surgery and/or inflammatory process. Most cases had microscopic features typically seen in malignant mesothelioma; however, some cases had confounding features such as signet-ring cells, spindle cells, clear cell changes, and adenomatoid tumor-like appearance. BAP-1 by immunohistochemistry was lost in 1/3 cases. Only 1 patient underwent genetic testing and had an MSH2 germline mutation. Homozygous deletion of CDKN2A by FISH was not found in 1 tested case, although next-generation sequencing identified a CDKN2A pathogenic mutation. 16/18 (88%) had surgical treatment, and some also received adjuvant chemotherapy. The mean overall survival (OS) of our patients was 80.4 months (95% confidence interval: 54.3-106.52); the 3-year OS was 79%, while the 5-year OS was 52.6%. Fifty-three percent of patients had recurrences and 20% had tumor progression. Although the limited sample precludes definitive conclusions, small tumor size, low-grade cytology, and low mitotic index appeared to be associated with an indolent behavior.

Localized biphasic malignant mesothelioma presenting as a giant pelvic wall mass: a rare case report and literature review. BMC Med Imaging 2020; 20:48. [PMID: 32375654 PMCID: PMC7203907 DOI: 10.1186/s12880-020-00443-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2019] [Accepted: 04/15/2020] [Indexed: 11/28/2022] Open
Abstract
Background Localized biphasic MPeM is rare in clinical practice, we reviewed 8 cases of localized biphasic MPeM (including our present case), and summarized the clinical and imaging features of the disease. Case presentation We reported a 79-year-old man with chief complaint of a narrowing in the caliber of the stool for one year. A soft tissue shadow was occasionally found by CT examination in the right pelvic wall, and it was diagnosed as localized biphasic malignant peritoneal mesothelioma (MPeM) by postoperative pathology. Radical excision was performed and no radio-chemotherapy was applied. Nearly six years after surgery, the mass was significantly enlarged, and the neighboring tissues including rectum, prostate, seminal vesicle, and right ischial ramus were all infiltrated. The patient was in the end stage of cancer with poor prognosis. Conclusions The localized biphasic MPeM may show following characteristics: (1) with heterogeneous low-density and obscure margin; (2) with low incidence rate of ascites; (3) with few central hemorrhage and necrosis; (4) with few calcified structures; (5) with mild to moderate heterogeneous delayed enhancement on contrast-enhanced CT. The imaging characteristics can provide further information for the diagnosis of localized biphasic MPeM in the future.

Abstract
Localized malignant mesotheliomas (LMM) is an uncommon and poorly recognized neoplasm. Its pathologic diagnosis is often surprising in patients with serosal/subserosal based localized tumors that are clinically suspicious for metastatic lesions or primary sarcomas. Once a tumor is diagnosed as "mesothelioma", LMM is often mistaken for diffuse malignant mesothelioma (DMM). Best currently available evidence about LMM was collected from the literature and cases diagnosed by members of the International Mesothelioma Panel (IMP). One hundred and one (101) LMM have been reported in the English literature. Patients had localized tumors with identical histopathologic features to DMM. Patients ranged in age from 6 to 82 years; 75% were men. Most (82%) of the tumors were intrathoracic. Others presented as intrahepatic, mesenteric, gastric, pancreatic, umbilical, splenic, and abdominal wall lesions. Tumors varied in size from 0.6 to 15 cm. Most patients underwent surgical resection and/or chemotherapy or radiation therapy. Median survival in a subset of patients was 29 months. Seventy two additional LMM from IMP institutions ranged in age from 28 to 95 years; 58.3% were men. Sixty tumors (83.3%) were intrathoracic, others presented in intraabdominal sites. Tumors varied in size from 1.2 to 19 cm. Median survival for 51 cases was 134 months. Best evidence was used to formulate guidelines for the diagnosis of LMM. It is important to distinguish LMM from DMM as their treatment and prognosis is different. A multidisciplinary approach is needed for the diagnosis of LMM as it shows identical histopathology and immunophenotype to DMM.

Abstract
RATIONALE Malignant mesothelioma is a malignant tumor with poor prognosis, which usually originates in the pleura, peritoneum, and pericardial cavity. Mesotheliomas that originate from the diaphragm are very rare. Here, we report a case of primary malignant mesothelioma of the diaphragm with liver invasion. PATIENT CONCERNS A 66-year-old woman was admitted to our hospital because of a "liver space-occupying lesion," without any special clinical symptoms. Imaging examinations suggested a cystic-solid mixed lesion in the right lobe of the liver. DIAGNOSIS The tumor was diagnosed as epithelioid mesothelioma of the diaphragm with liver invasion. INTERVENTION The patient underwent abdominal surgery in our hospital to remove the diaphragmatic mass, liver mass, and part of the diaphragm. OUTCOMES The postoperative course was uneventful. LESSONS Primary diaphragmatic malignant mesothelioma is very rare and may involve liver or lung tissue and be mistaken for liver or lung tumor. Accurate diagnosis depends on careful pathological examination. Immunohistochemical staining is very useful to distinguish this tumor from other liver or diaphragmatic tumors.

Abstract
Background Malignant peritoneal mesothelioma is a rare aggressive tumor of the peritoneum. We report a rare case of resection of multiple localized malignant peritoneal mesotheliomas. Case presentation A 55-year-old Japanese woman was admitted to our hospital because liver tumors were detected by abdominal ultrasonography during a screening examination. Blood examination findings, including tumor makers, were within normal ranges. She had no evidence of exposure to asbestos. Computed tomography showed four hypervascular, round liver tumors, one in the lateral liver segment adjacent to the hepatic hilus, and the other three on the liver surface. Computed tomography angiography revealed that the tumor in the lateral segment had strong enhancement and was fed from the left gastric artery. In contrast, the other tumors showed no enhancement, and were fed from the right inferior phrenic artery. Abnormal accumulation was identified in the four tumors only with 18F-fluorodeoxyglucose positron emission tomography. It was very difficult to obtain a definitive preoperative diagnosis, but surgical resection was performed because we considered potential malignancy. Laparotomy revealed the principal site of the tumor in the lateral segment was on the hepatoduodenal ligament, and all other tumors were on the diaphragm. A left lobectomy and partial diaphragmatic resection were performed. The final pathological diagnosis was multiple malignant epithelioid mesotheliomas. Our patient has had no recurrence for 20 months postoperatively. Conclusions In general, malignant peritoneal mesotheliomas are classified as diffuse tumors, which are often unresectable and have a poor prognosis. However, early diagnosis and treatment, particularly with the localized type, as in our patient, could lead to long-term survival of the patient. We recommend that multiple malignant epithelioid mesotheliomas be included in the differential diagnosis for patients with subcapsular hepatic tumors.

Abstract
INTRODUCTION Primary Intrahepatic mesotheliomas are malignant tumors arising from the mesothelial cell layer covering Glisson's capsule of the liver. They are exceedingly rare with only fourteen cases reported in the literature. They have nonspecific signs and symptoms and need a high index of suspicion and an extensive workup prior to surgery. Surgery remains the mainstay of treatment. PRESENTATION OF CASE 48 year old male presented with a 3 months history of abdominal pain, productive cough, anemia and weight loss. He had no history of asbestos exposure. A computed tomography scan and magnetic resonance study demonstrated a heterogeneous subscapular mass within the dome of the right hepatic lobe measuring 11.3 × 6.1 cm involving the diaphragm. Combined resection of the liver and diaphragm was performed to achieve negative margins. Pathology demonstrated an epithelioid necrotic intrahepatic mesothelioma that stained positive for calretinin, CK AE1/AE3, WT-1, D2-40 and CK7. DISCUSSION Primary intrahepatic mesotheliomas originate from the mesothelial cells lining Glisson's capsule of the liver. They predominantly invade the liver but may also abut or involve the diaphragm. Surgery should include a diagnostic laparoscopy to rule out occult disease or diffuse peritoneal mesothelioma. Complete resection with negative margins should be attempted while maintaining an adequate future liver remnant. Attempts at dissecting the tumor off the involved diaphragm will result in excessive bleeding and may leave residual disease behind. CONCLUSION Intrahepatic mesotheliomas are rare peripherally-located malignant tumors of the liver. They require a high index of suspicion and a comprehensive workup prior to operative intervention.

Abstract
Background Malignant mesothelioma commonly arises from the pleura, but can also arise from the peritoneum, pericardium, and tunica vaginalis testis. However, malignant mesothelioma of the liver is extremely rare and coexistence with malignant mesothelioma of the greater omentum has not been described in the literature. In this case report, we present a case of multiple malignant mesothelioma of the liver and greater omentum. Case presentation A 36-year-old woman was admitted to our hospital for the evaluation of an elastic hard mass in the right upper abdomen. Abdominal contrast computed tomography showed a cystic mass measuring 13 × 14 × 11 cm in the right liver lobe with enhanced mural nodule. Abnormal accumulation was identified in the liver and lower abdominal area on 18F-fluorodeoxyglucose positron emission tomography. The patient underwent hepatectomy of the posterior segment and partial resection of the omentum. The final pathological diagnosis was low-grade multiple malignant epithelioid mesothelioma based on characteristic immunohistochemical findings. As of 6 months postoperatively, the patient has shown no disease recurrence. Conclusions We present the first case of a 36-year-old woman with multiple malignant mesothelioma of the liver and greater omentum.
