The purpose of the present study is to asses the value of high frequency ultrasonography (20 MHz), a new noninvasive imaging technique, in cutaneous tumors. Cutaneous tumors are clinically varied and their diagnosis is still based on histopathological analysis. 140 cutaneous tumors have been examined with US and imaging findings have been compared to the results of clinical and histological examinations. This study shows that high frequency ultrasonography, even though it cannot replace pathological analysis, may help the dermatologist in the positive diagnosis of some cutaneous tumors and in accessing the location and the in depth-extension of the lesions in the different layers of the skin.

Methyltransferase-like 1 (METTL1)-mediated m7G modification is a common occurrence in various RNA species, including mRNAs, tRNAs, rRNAs, and miRNAs. Recent evidence suggests that this modification is linked to the development of several cancers, making it a promising target for cancer therapy. However, the specific role of m7G modification in cutaneous squamous cell carcinoma (cSCC) is not well understood.

Background: Programmed cell death 1 (PD-1) signaling blockade by immune checkpoint inhibitors (ICI) effectively restores immune surveillance to treat melanoma. However, chronic interferon-gamma (IFNγ)-induced immune homeostatic responses in melanoma cells contribute to immune evasion and acquired resistance to ICI. Poly ADP ribosyl polymerase 14 (PARP14), an IFNγ-responsive gene product, partially mediates IFNγ-driven resistance.

A calcifying epithelial odontogenic tumour (CEOT) is a rare benign odontogenic tumour of epithelial origin accounting for approximately 1% of all odontogenic tumours. The intraosseous form occurs more commonly in the posterior mandible whereas the extraosseous form is common in the anterior maxilla. CEOT is often asymptomatic and presents with a painless swelling of the mandible.
