Published: March 2016

Background: The histopathological diagnosis of malignant mesothelioma is based mainly on the immunohistological profile of the neoplasia, using different immunohistochemical markers to distinguish between a malignant mesothelioma and a carcinoma.

Case Report: A female patient presented with a right paravertebral rapidly growing tumor and severe pain. Based on the immunohistochemical findings, we present the first case of a malignant mesothelioma with immunohistochemical expression of thyroid transcription factor-1.

Conclusions: The detection of a positive reaction for thyroid transcription factor-1 in the tumor cells may not exclude a malignant mesothelioma.

Malignant pleural mesothelioma (MPM) is a rare neoplasm with increasing incidence and mortality rates. Although recent advances have improved the overall prognosis, they have not had an important impact on survival of patients with MPM, such that more effective treatments are needed. Some species of marine snails have been demonstrated to be potential sources of novel anticancer molecules.

Cell therapies, including tumor antigen-loaded dendritic cells used as therapeutic cancer vaccines, offer treatment options for patients with malignancies. We evaluated the feasibility, safety, immunogenicity, and clinical activity of adjuvant vaccination with Wilms' tumor protein (WT1) mRNA-electroporated autologous dendritic cells (WT1-mRNA/DC) in a single-arm phase I/II clinical study of patients with advanced solid tumors receiving standard therapy. Disease status and immune reactivity were evaluated after 8 weeks and 6 months.

Malignant peritoneal mesothelioma (MPM) is a rare and aggressive malignancy of mesothelial cells in the peritoneum. Herein, we describe the 68Ga-FAPI and 18F-FDG PET/CT findings of MPM in a 41-year-old man. In the present case, the primary and metastatic tumors showed intense 68Ga-FAPI accumulation but no significantly increased 18F-FDG uptake.

BRCA1-associated protein 1 (BAP1) is a tumor suppressor gene that was first identified in 1998. Germline loss of functional variants in BAP1 is associated with a tumor predisposition syndrome with at least four cancers; uveal melanoma (UM), malignant mesothelioma (MMe), renal cell carcinoma (RCC), and cutaneous melanoma (CM). Furthermore, somatic BAP1 mutations are important drivers for several cancers most notably UM, MMe, RCC, intrahepatic cholangiocarcinoma (ICC) and hepatocellular carcinoma (HCC).

Background: Rosai-Dorfman disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy, is a rare non-malignant disorder characterized by excessive proliferation of histiocytes, the cause of which remains unknown. Although the lymph nodes are the most commonly affected site, some patients may present with extranodal involvement, particularly in the skin, nasal cavity, eyes, and bones. In this report, we aim to present a unique case of RDD with pleural involvement in a 61-year-old patient.
