There are many histologic types of gynecologic malignancies. I reviewed three rare ovarian tumor types that have poor prognoses. Ovarian mesonephric-like adenocarcinoma (MLA) is a newly described histological type known for its aggressive behavior.

Introduction: Primary squamous cell carcinoma (SCC) is a rare type of pancreatic cancer with an extremely low incidence rate and a prognosis that is poorer than that of pancreatic ductal adenocarcinoma.
Presentation Of Case: We report a case of pure pancreatic SCC in an 80-year-old man. Based on the examination before surgical resection, we did not detect any SCC lesions that might have metastasized to the pancreas.
Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer worldwide. HPV-negative HNSCC, which arises in the upper airway mucosa, is particularly aggressive, with nearly half of patients succumbing to the disease within five years and limited response to immune checkpoint inhibitors compared to other cancers. There is a need to further explore the complex immune landscape in HPV-negative HNSCC to identify potential therapeutic targets.

Objective: This study was aimed at investigating the roles of podoplanin (PDPN) as a marker associated with malignant development, progression, and poor prognosis in oral leukoplakia and various forms of oral squamous cell carcinoma (OSCC), particularly in relation to the extent of invasion.
Methods: Immunohistochemical analysis of PDPN was conducted on 77 histologically confirmed, formalin-fixed, paraffin-embedded samples representing various degrees of OSCC invasion and dysplasia grades.
Results: The samples were analyzed with Fisher's exact test and the Kruskal-Wallis test.

Head and neck squamous cell carcinoma (HNSCC) is an aggressive cancer that is notably associated with a high risk of lymph node metastasis, a major cause of cancer mortality. Current therapeutic options remain limited to surgery supplemented by radio- or chemotherapy; however, these interventions often result in high-grade toxicities. Distant metastasis significantly contributed to the poor prognosis and decreased survival rates.
