The study aimed at checking if MAGE-A expression in oral leukoplakia (OLP) lesions is related to malignant transformation. The 48 samples of OLP that transformed to oral squamous cell carcinoma (OSCC) (group 1) and 50 samples of OLP that did not transform to OSCC (group 2) were included in the study. The expression of MAGE-A was restricted to group 1. The correlation between malignant transformation and MAGE-A occurrence in OLP was statistically significant (p < .0001). Detection of MAGE-A may allow identifying OLP with a high risk of malignant transformation giving a view to a new approach to prevention of oral cancer.

Medullary thyroid cancer (MTC) is a frequently metastatic tumor of the thyroid that develops from the malignant transformation of C-cells. These tumors most commonly have activating mutations within the RET or RAS proto-oncogenes. Germline mutations within RET result in C-cell hyperplasia, and cause the MTC pre-disposition disorder, multiple endocrine neoplasia, type 2A (MEN2A).

Over the past decade, immune checkpoint inhibitors (ICIs) have transformed the treatment of cancer, though they come with the risk of immune-related adverse (irAEs) events such as hepatotoxicity or Immune-mediated Liver Injury from Checkpoint Inhibitors (ILICI). ILICI is a serious irAE that, when severe, requires cessation of ICI and initiation of immunosuppression. Cytotoxic T Lymphocytes (CTLs) play a central role in ILICI; however, they are just part of the picture as immunotherapy broadly impacts all aspects of the immune microenvironment and can directly and indirectly activate innate and adaptive immune cells.

Stem cell implantation holds promise for enhancing bone repair, but risks of pathogen transmission and malignant cell transformation should not be ignored. Compared to stem cell implantation, recruitment of endogenous stem cells to injured sites is more critical for in situ bone regeneration. In this study, based on the acidic microenvironment of bone injury, an HG-AA-SDF-1α composite hydrogel with a dual-control intelligent switch function is developed by incorporating stromal cell-derived factor (SDF-1α), arginine carbon dots (Arg-CDs), and calcium ions (Ca) into the oxidized hyaluronic acid/gelatin methacryloyl (HG) hydrogel.

Mixed epithelial and stromal tumor (MEST) of the kidney is a rare benign neoplasm composed of both stromal and epithelial components. MEST is mainly seen in adults with a strong predilection for perimenopausal women with history of hormone replacement therapy. While MEST is generally benign, there are reported cases of malignant transformation and adverse clinical outcomes.

Malignant transformation is a rare complication of ovarian mature cystic teratoma that occurs in 1-3% of cases. We herein report a case of squamous cell carcinoma originating from mature cystic teratoma of the ovary diagnosed 10 years after initial tumor detection. A 69-year-old woman presented to the Department of Internal Medicine with a seven-month history of abdominal fullness.
