Primary intracranial squamous cell carcinoma is extremely rare, with most cases arising from malignant transformation of dysembryogenetic lesions such as epidermoid and dermoid cysts. Intracranial squamous cell neoplasm arising de novo is even rarer and has been reported in only four patients to date. We herein describe a case of primary intracranial squamous cell carcinoma arising de novo in the right frontal lobe in a 35-year-old woman treated with a combination of surgery and postoperative conformal radiation. We have also shed light on the biology and the therapeutic options of this enigmatic tumour.

The gastrointestinal tract is a prominent portal of entry for HIV-1 during sexual or perinatal transmission, as well as a major site of HIV-1 persistence and replication. Elucidation of underlying mechanisms of intestinal HIV-1 infection are thus needed for the advancement of HIV-1 curative therapies. Here, we present a human 2D intestinal immuno-organoid system to model HIV-1 disease that recapitulates tissue compartmentalization and epithelial-immune cellular interactions.

The use of dental implants to replace lost or damaged teeth has become increasingly widespread due to their reported high survival and success rates. In reality, the long-term survival of dental implants remains a health concern, based on their short-term predicted survival of ~15 years, significant potential for jawbone resorption, and risk of peri-implantitis. The ability to create functional bioengineered teeth, composed of living tissues with properties similar to those of natural teeth, would be a significant improvement over currently used synthetic titanium implants.

Metastasis in patients with oral squamous cell carcinoma has been associated with a poor prognosis. However, sensitive and reliable tests for monitoring their occurrence are unavailable, with the exception of PET-CT. Circulating tumor cells and cell-free DNA have emerged as promising biomarkers for determining treatment efficacy and as prognostic predictors in solid tumors such as breast cancer and colorectal cancer.

Objective: To explore the clinical efficiency of using the sentinel lymph node (SLN) imaging agent Tc-rituximab for lymphoscintigraphy and SLN biopsy (SLNB) in oral squamous cell carcinoma (OSCC) patients.
Methods: A retrospective study was conducted on 23 patients with OSCC who underwent Tc-rituximab lymphoscintigraphy and SLNB. The cohort comprised 16 men (69.
