Objective: To describe the clinical case of a patient presenting a squamous cell carcinoma in a duplicated renal pelvis, after percutaneous nephrolithotomy.
Methods/results: 60-year-old male patient who was diagnosed of a squamous cell carcinoma of the renal pelvis in the pathological study of a lower pole nephrectomy after percutaneous nephrolithotomy for staghorn calculi in the left lower pole renal moiety. The patient suffered a bladder recurrence one year and a half later. A radical cystoprostatectomy was performed, but the patient died in a few months due to metastasis.
Conclusions: Squamous cell carcinoma of the renal pelvis is a rare tumor with poor prognosis, associated with stone disease and chronic infection. Taking biopsies from suspicious lesions during percutaneous nephrolithotomy may help early diagnosis and improve survival.

Background: Head and neck squamous cell carcinoma (HNSCC) is a very aggressive disease characterized by a heterogeneous tumor immune microenvironment (TIME). Tumor-associated macrophages (TAMs) constitute the major innate immune population in the TIME where they facilitate crucial regulatory processes that participate in malignant tumor progression. SPP1 + macrophages (SPP1 + Macs) are found in many cancers, but their effects on HNSCC remain unknown.

Background: Oral squamous cell carcinoma (OSCC) is an aggressive malignancy with poor prognosis. Neutrophil infiltration has been associated with unfavorable outcomes in OSCC, but the underlying molecular mechanisms remain unclear.
Methods: This study integrated single-cell transcriptomics (scRNA-seq) with bulk RNA-seq data to analyze neutrophil infiltration patterns in OSCC and identify key gene modules using weighted gene co-expression network analysis (hdWGCNA).

Background: Hepatocellular carcinoma (HCC) is the leading cause of cancer-related deaths worldwide, and the lack of effective biomarkers for early detection leads to poor therapeutic outcomes. Prostaglandin E Synthase 3 (PTGES3) is a putative prognostic marker in many solid tumors; however, its expression and biological functions in HCC have not been determined. The proteolysis-targeting chimera (PROTAC) is an established technology for targeted protein degradation.

Background: Mixed adenoneuroendocrine carcinoma (MANEC) of the cervix is a rare malignant tumor with high malignancy and poor prognosis, of which large-cell neuroendocrine carcinoma and HPV-independent adenocarcinoma are particularly rare, which have been reported limitedly in the literature. Here, we present 2 cases of MANEC of the cervix and discuss important considerations for diagnosing cervical poorly differentiated carcinoma.
Case Presentation: we reported two cases of mixed large cell neuroendocrine carcinoma and adenocarcinoma of the cervix, one HPV-independent and one HPV-associated, both with vaginal bleeding.

Background: Clear cell renal cell carcinoma (ccRCC) is a type of cancer characterized by a vast intracellular accumulation of lipids that are critical to sustain growth and viability of the cells in the tumour microenvironment. Stearoyl-CoA 9-desaturase 1 (SCD-1) is an essential enzyme for the synthesis of monounsaturated fatty acids and consistently overexpressed in all stages of ccRCC growth.
Methods: Human clear cell renal cell carcinoma lines were treated with small-molecule inhibitors of protein kinase CK2.
