Only a few human ovarian endometrioid carcinoma cell lines are currently available, partly due to the difficulty of establishing cell lines from low-grade cancers. Here, using a cell immortalization strategy consisting of i) inactivation of the p16-pRb pathway by constitutive expression of mutant cyclin-dependent kinase 4 (R24C) (CDK4) and cyclin D1, and ii) acquisition of telomerase reverse transcriptase (TERT) activity, we established a human ovarian endometrioid carcinoma cell line from a 46-year-old Japanese woman. That line, designated JFE-21, has proliferated continuously for over 6 months with a doubling time of ~ 55 h.

: Acinic cell carcinoma (ACC) is a rare lung neoplasm that can affect both children and adults as a parenchymal or endobronchial mass. It is histologically similar to this kind of tumor described in salivary glands, but with a different immunophenotype. In general, it poses a reduced degree of malignancy, with indolent growth and a favorable prognosis, with exceptionally rare cases associated with recurring disease or lymph node metastases.

Among the mechanisms, cancer cells develop to elude immune system, immune regulation and the use of molecules that play important roles in immune escape stand out. One of these molecules, the human leukocyte antigen G (HLA-G), plays an important role in the maintenance of immune tolerance and contributes to the progression of cancer by exerting an immunosuppressive effect. By creating an immunosuppressive field in the microscopic environment of the tumor, the aberrant expression of HLA-G facilitates the evading of cancer cells from the immune system and contributes to the progression of the disease.

Pilomatrix carcinoma (PC) is a rare malignant adnexal tumor originating from follicular matrix cells primarily impacting Caucasian males. This review provides a comprehensive analysis of scientific literature on PC through an exploration of 206 cases reported between 1980 and 2024. We discuss the epidemiology, clinical presentation, histopathology, and diagnostic challenges of PC, and explore various treatment methods for this rare malignancy as well as their associated outcomes.

Introduction: Neuroblastoma is an embryonic tumor of the peripheral sympathetic nervous system. It is the most common extracranial solid tumor of childhood and accounts for up to 15% of all pediatric cancer fatalities. The manifestation of neuroblastoma is variable depending on the location of the tumor and the presence or absence of paraneoplastic syndromes.
