December 2nd, 2008. Monitoring of Chemotherapy Response in Malignant Pleural Mesothelioma Using Fluorodeoxyglucose Positron Emission Tomography
The tumor lesion exhibited shrinkage on CT and a decrease in the standardized uptake value (SUV) max after the first course of chemotherapy, but exhibited size enlargement and an increase in SUV max after the second course of chemotherapy. These findings suggest that results of quantification of metabolic response by FDG-PET are related to the objective response as determined by CT in patients with MPM.

November 17th, 2008. Malignant mesothelioma of the tunica vaginalis of the testis without exposure to asbestos
Conclusion: In conclusion, though a rare tumor, malignant mesothelioma of the tunica vaginalis of the testis should be considered whenever a paratesticular mass lesion is seen even without a history of trauma or asbestos exposure as is highlighted in this case. Ultrasound findings are helpful and fine needle aspiration of the tumor may assist in arrival at a diagnosis. Surgical orchidectomy remains the modality of treatment.
November 8th, 2008. Effective chemotherapy based on a chemosensitivity test for malignant pleural mesothelioma
Numerous chemotherapeutic agents have been tested in many clinical trials, but the response rate does not exceed 20% for most of the investigated regimens. Here we report a case of MPM in which the chemotherapy based on the chemosensitivity test was very effective on palliation with stable disease for a long time.
November 6th, 2008. Benign mesothelioma of peritoneum presenting as a pelvic mass
Postoperative recovery was satisfactory. At 3 years follow-up, patient is symptom-free.
November 5th, 2008. Malignant mesothelioma of the tunica vaginalis: a case report
The patient has not received additional therapy because there has been no evidence of metastasis. He has been free of disease 3 months postoperatively.
November 5th, 2008. Case of malignant mesothelioma presenting as a perineal and intrascrotal mass
The patient died six months after the initiation of therapy. To our knowledge, 24 cases of malignant mesothelioma in the perineum or intrascrotum were reported in Japan and this case was thought to be the 25th case in Japan.
November 5th, 2008. Polyneuropathy in a patient with malignant pleural mesothelioma: a paraneoplastic syndrome
The patient was treated with immunoglobulin and prednisolone, and this resulted in subjective, objective, and paraclinical improvement of the symptoms. We therefore suggest that polyneuropathy is a possible paraneoplastic syndrome in MPM.
October 22nd, 2008. A case of solid pseudopapillary tumour of the pancreas and malignant mesothelioma
Discussion: An abdominal computerised tomogram revealed pancreatic body mass arising. Pleural fluid cytology and a pleural biopsy failed to demonstrate malignancy. The pancreatic tumour was resected by distal pancreatectomy, segmental colectomy and splenectomy. The tumour was a solid pseudopapillary pancreatic tumour (SPT) with a high metastatic potential. The patient deteriorated and a repeat biopsy of the thickened pleura confirmed malignancy which was initially thought to be metastases from the SPT. Immunohistochemical staining confirmed malignant mesothelioma. The patient developed liver metastases and died 2 years from the diagnosis of metastatic disease.

October 16th, 2008. Cardiac tamponade as primary manifestation of angioimmunoblastic T-cell lymphoma (AILT). Coexistence with malignant mesothelioma
Conclusion: CT as primary clinical manifestation of AILT is very rare. This case reflects the differences in the underlying biology of AILT and consequently the vast spectrum of its clinical presentations. Coexistence of AILT with malignant pleural mesothelioma is also extremely rare.
October 8th, 2008. Acute abdomen in an asbestos factory worker
We treated a man who had a primary peritoneal mesothelioma with an unusual presentation — an acute abdomen. We report this case and discuss the relevant literature.
September 30th, 2008. Mesothelial reaction in longstanding Crohn’s ileitis simulating papillary mesothelioma
The peritoneal surface of the ileal resection specimen displayed exuberant tubulo-papillary formations of the mesothelium, with superficial invasion of the underlying stroma. The case demonstrates the well-recognised difficult differential diagnosis between a benign mesothelial proliferation and malignant mesothelioma in a novel clinical setting, and the diversity of the extramural manifestations of Crohn's disease.
September 27th, 2008. Treatment of peritoneal mesothelioma in pediatric patients
Treatment was well tolerated, and three of these patients have achieved long-term survival. The fathers of three of the patients worked in the construction industry and may have been the source of indirect asbestos exposure.

September 17th, 2008. Metastasis of Malignant Peritoneal Epithelioid Mesothelioma in Endoscopic Gastric Biopsy: A Diagnostic Pitfall
Conclusions: Metastases of malignant peritoneal mesotheliomas are unusual, and a predominantly gastrointestinal localization is rare. Pathologists should be aware of this possibility to avoid misdiagnosis, particularly in small biopsy specimens.
September 12th, 2008. Inguinal lymph node as the only evidence of progressive lung cancer
The primary tumours of these cases were malignant mesothelioma, salivary duct and breast carcinoma. In this paper, we report a case of carcinoma of the lung metastatic to an inguinal lymph node as the only evidence of progressive lung cancer.
August 30th, 2008. Metastatic appendiceal mucinous adenocarcinoma to well-differentiated diffuse mesothelioma of the peritoneal cavity: a mimicker of florid mesothelial hyperplasia in association with neoplasms
Although commonly associated with atypical/ florid mesothelial hyperplasia, a carcinoma can rarely metastasize to a well-differentiated mesothelioma, which can pose significant diagnostic difficulties because it can mimic a reactive process. This unusual case report expands the spectrum of mesothelial proliferation in conjunction with a malignant neoplasm and serves to remind pathologists that such a concomitant occurrence exists.
August 19th, 2008. Primary malignant mesothelioma developed in liver
A local recurrence was noted 15 months after surgery, which was treated by radiofrequency ablation. At 23 months after initial surgery, locally recurrent masses with direct invasion of the diaphragm and a solitary intrahepatic metastasis were noted, which was treated by partial excision of the diaphragm with intraoperative RFA after transarterial chemoembolization.
August 14th, 2008. Full-thickness pleural biopsy using an Insulation-tipped Diathermic knife in a patient with malignant pleural mesothelioma
Pathology revealed extensive fibrosis and epithelial mesothelioma by the specimen. This biopsy technique using IT knife through semiflexible thoracoscopy enabled to obtain a full-thickness pleura It is thought to be useful for the diagnosis of malignant pleural mesothelioma (MPM) in which standard forceps are difficult to grasp.
August 1st, 2008. Establishment of a human malignant fibrous mesothelioma cell line and the biological characteristics compared with malignant epithelial mesothelioma cell line
1, among others may be a major mechanism of malignant mesothelioma carcinogenesis. We considered and supported the combination theory for the histogenesis of malignant mesothelioma.
July 25th, 2008. Environmental exposure to Libby asbestos and mesotheliomas
Results: These exposures are considered to be of a low degree of magnitude, but are similar to those in Western Australia's crocidolite mine at Wittenoom Gorge. An epidemic of mesothelioma can likely be expected from this type of asbestos contamination over the next 20 plus years.
July 24th, 2008. Primary yolk sac tumor of the omentum: a case report and review of the literature
Conclusion: To our knowledge this is the fourth case of primary omental YST. A review of the literature indicates that the diagnosis of YST requires proper evaluations of tumor makers and a skilled pathologist for analysis of frozen sections.
