Published: September 2016

Biphasic malignant pleural mesothelioma is a rare malignant tumor, usually presenting as a pleural-based mass in a patient with history of chronic asbestos exposure. We herein report a case of a 41-year-old man who presented with chest pain and had a chest computed tomography (CT) scan suggestive of a primary skeletal tumor originating from the ribs (chondrosarcoma or osteosarcoma), with no history of asbestos exposure. CT-guided core needle biopsies were diagnosed as malignant sarcomatoid mesothelioma. Surgical resection and chest wall reconstruction were performed, confirming the diagnosis and revealing a secondary histologic component (epithelioid), supporting the diagnosis of biphasic malignant mesothelioma.

Background: Somatostatin receptors (SSTRs) are expressed in most neuroendocrine neoplasms, particularly in gastroenteropancreatic neuroendocrine tumours, and have been utilised as diagnostic markers and therapeutic targets. The radioiodinated somatostatin analogue 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid- Tyr3-octreotate (DOTATATE) has been employed for SSTR targeting for either diagnostic or therapeutic purposes depending on the labelling with Gallium or Lutetium, respectively. SSTR expression is reported in a subset of breast adenocarcinoma and breast neuroendocrine carcinomas; however, minimal knowledge exists regarding their expression in fibroepithelial (biphasic) breast lesions such as fibroadenoma and phyllodes tumours.

The extracellular matrix (ECM) is a complex structure involved in many biological processes with collagen being the most abundant protein. Density of collagen fibers in the matrix is a factor influencing cell motility and migration speed. In cancer, this affects the ability of cells to migrate and invade distant tissues which is relevant for designing new therapies.

Kaposi's sarcoma-associated herpesvirus is an oncogenic gammaherpesvirus that plays a major role in several human malignancies, including Kaposi's sarcoma, primary effusion lymphoma, and multicentric Castleman's disease. The complexity of KSHV biology is reflected in the sophisticated regulation of its biphasic life cycle, consisting of a quiescent latent phase and virion-producing lytic replication. KSHV expresses coding and noncoding RNAs, including microRNAs and long noncoding RNAs, which play crucial roles in modulating viral gene expression, immune evasion, and intercellular communication.

Synovial sarcoma is an aggressive soft-tissue cancer that shows limited responses to current immunotherapeutic approaches using immune checkpoint blockade or adoptive cell therapy. To improve immunotherapy for this cancer, understanding how the immune cells in the tumor microenvironment associate with histological subtype, disease progression and current therapies is vital. To evaluate the immune infiltrate in synovial sarcoma in relation to histological subtype, disease progression and in response to cytotoxic treatment, we performed immunodetection of T cells, CD68 myeloid cells, endothelial cells and keratin on a series of 41 synovial sarcoma patients at various stages of disease.
