Cervical Mesonephric Adenocarcinoma Treated with Neoadjuvant Chemotherapy: A Case Report and a Literature Review.

Introduction: Cervical mesonephric ductal adenocarcinoma (MA) is an HPV-independent adenocarcinoma that occurs in middle-aged women. MA originates from remnants of the Wolffian duct that usually regress in females once the induction of sex differentiation is activated. MA is a rare disease that accounts for less than 1% of all cervical adenocarcinomas.

Extended 73-month survival in an elderly patient with BRAF V600E-mutated lung adenocarcinoma: A case report.

BRAF is a mediator that activates the mitogen-activated protein kinase pathway. A mutation in BRAF can cause abnormal pathway activation, leading to cell proliferation. In a Phase II study, the combination therapy of the BRAF inhibitor dabrafenib and the MEK inhibitor trametinib was found to be effective in non-small cell lung cancer (NSCLC) patients with the BRAF mutation.

Cotyledonoid dissecting leiomyoma with peritoneal dissemination.

Cotyledonoid dissecting leiomyoma (CDL) is a rare benign uterine leiomyoma that macroscopically shows multinodular placenta-like growth. Its border with the myometrial layer is unclear, making it clinically difficult to differentiate from uterine sarcoma. CDL is often misdiagnosed.

The association between CD34 expression status and the clinicopathological behavior of dedifferentiated liposarcoma.

Lipogenic and fibrous tumors are thought to originate from CD34-positive stromal fibroblastic/fibrocystic cells. Well-differentiated lipogenic tumors typically express CD34, whereas dedifferentiated liposarcoma (DDLPS) often loses it. We conducted survival analyses involving 59 patients with DDLPS.

A Case of Anti-Synthetase Syndrome With Anti-Glycyl tRNA Synthetases Antibody Developed After COVID-19.

Coronavirus disease 2019 (COVID-19) is a life-threatening respiratory disease characterized by severe acute infection. In some cases, COVID-19 symptoms may persist for a long term, posing a significant social problem. Long-term COVID-19 symptoms resemble those observed in various autoimmune diseases, such as dermatomyositis and polymyositis.
