Phosphaturic mesenchymal tumors (PMTs) are rare mesenchymal neoplasms of soft tissue or bone origin that can give rise to a challenge in diagnostic imaging. These tumors are frequently associated with tumor-induced osteomalacia, also called oncogenic osteomalacia, which is a rare paraneoplastic syndrome characterized by ectopic secretion of fibroblast growth factor 23, a hormone that regulates serum phosphate level. PMTs show polymorphic features on both radiological findings and histological examination, causing problems in diagnosis owing to their similarity with other mesenchymal tumors. Thus, this paper aims to describe radiological aspects of PMTs and suggest an imaging pathway for accurate diagnosis throughout the evidence from the literature review.

Superficial CD34+ fibroblastic tumor (SCD34FT) is a relatively recently described borderline mesenchymal neoplasm. Owing to a relative lack of specificity in clinical presentation, radiopathologic findings, and immunohistochemical staining, the diagnoses of SCD34FT can be challenging. In this study, we present a case of a 55-year-old woman with an indolent painless nodule on the right shin.

Paediatric renal tumours include a broad range of neoplasms which largely differ, but also overlap to a smaller extent, with adult kidney cancer. These include the embryonal tumour nephroblastoma, which accounts for the majority of cases of kidney cancer in the first decade of life and, despite boasting a cure in ~ 90% cases, still presents clinical challenges in a small proportion of cases. A variety of less common mesenchymal tumours, including the mostly indolent congenital mesoblastic nephroma, clear cell sarcoma of kidney which continues to be associated with poor outcomes for higher stage disease, and the typically lethal malignant rhabdoid tumour, form the bulk of the remaining presentations in the first decade.

miR-155 exhibits variable expression in different tumors and fulfills diverse biological roles. However, specific molecular mechanisms by which miR-155-5p, which is under-expressed in prostate cancer (PCa), operates are yet to be elucidated. The role of the enhancer of zeste 2 (EZH2)/miR-155-5p axis in PCa was determined by using bioinformatics tools and performing luciferase reporter assay, chromatin immunoprecipitation PCR, CCK-8 assays, cell migration and invasion assays, RNA isolation, reverse transcription quantity (RT-qPCR) and Western blot.

The long non-coding RNA (lncRNA) metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) is highly expressed in multiple types of tumour tissues and may be associated with the growth of PC cells. In this study, we aimed to assess the role and possible mechanisms of MALAT1 in PC progression.

A male in his seventies presented with lung cancer in the right lower lobe. The surgically resected specimen revealed a pleomorphic carcinoma featuring an adenocarcinoma component with lepidic, acinar, and papillary patterns, alongside a spindle cell component spreading along the pulmonary artery wall, resembling intimal sarcoma. The spindle tumor cells were positive for keratins, TTF-1, napsin A, and vimentin, but negative for p40, CK14, desmin, alpha-smooth muscle actin, CDK4, and MDM2.
