Eccrine pore carcinoma is an infrequent malign skin tumour that derives from the eccrine sweat glands, it fundamentally affects persons of advanced age, its growth is slow and it is predominantly located in the lower extremities. Its high malignancy and its potentiality for giving rise to distant metastasis makes it necessary to carry out aggressive surgical treatments with lymphadenectomies of the ganglion chains. There are no more than 300 tumours of this type described in the literature. Our study examines 9 cases detected in Navarra in the last ten years and analyses its clinical and histopathological behaviour. The chosen surgical treatment was extirpation with safety margins of 2 cm; we did not carry out prophylactic lymphadenectomies. At present the survival rate of patients is 100% and only in one of the series has a lymphatic metastasis been detected.

Head and neck squamous cell carcinoma (HNSCC) are invasive solid tumors accounting for high mortality. To improve the clinical outcome, a better understanding of the tumor and its microenvironment (TME) is crucial. Three -dimensional (3D) bioprinting is emerging as a powerful tool for recreating the TME in vitro.

Donafenib is an improved version of sorafenib in which deuterium is substituted into the drug's chemical structure, enhancing its stability and antitumor activity. Donafenib exhibits enhanced antitumor activity and better tolerance than sorafenib in preclinical and clinical studies. However, the specific mechanism of its effect on hepatocellular carcinoma has not been reported.

Thyroid cancer continues to be a notable health issue, requiring the creation of novel treatment methods to enhance patient results. The objective of this study is to investigate the potential of utilizing bee venom (BV)-loaded zeolitic imidazolate framework-8 (ZIF-8) nanoparticles as a novel strategy for specifically targeting and treating medullary thyroid cancer cells. Due to their wide surface area and configurable pore size, ZIF-8 nanoparticles are ideal for drug delivery.
