Background: Non-infectious granulomatous disorders of the upper lip represent a special chapter of oral and maxillofacial pathology. In this work we report a case-series of this process, to analyse its main clinicopathological features and find differential data that allow us improve its diagnosis and understand its pathogenesis.
Methods: We present 11 cases of non-infectious granulomatous disorders of the upper lip, 8 women and 3 men with an age range of 29-84 years, who have been attended at the Oral Medicine Department of the IUCT (France) and the Oral Medicine Unit of the UPV/EHU (Spain).
Commenting on a recently published article on sicca syndrome linked to immune checkpoint inhibitor therapy, this letter to the editor shares another viewpoint on the management of this immune‐related adverse event.

Patients And Methods: This prospective study enrolled 15 patients who underwent F-NaF and F-FDG PET/CT. We compared the delineations of bone invasions obtained with F-NaF PET/CT and F-FDG PET/CT with the results of histopathological analysis of mandibular resections (from right and left bone borders).
Oral lichen planus (OLP) is a chronic inflammatory disease considered as a CD8+ T lymphocyte-mediated autoimmune reaction, which may be triggered by undetermined virus. Recent reports have described the detection of Merkel cell polyomavirus (MCPyV) DNA in oral samples from healthy patients and in patients with different forms of oral cancers. We therefore investigated in a prospective way whether MCPyV was detectable in oral lesions of patients with active OLP.

The most important differential diagnostic considerations of MASC are low-grade adenocarcinoma not otherwise specified (NOS), cystadenocarcinoma, and acinic cell carcinoma (AciCC). These tumors may share an overlapping morphology with MASC, and additional immunohistochemical studies are required to reinforce the diagnosis.

- Primary hyperparathyroidism (PHP) can be caused by benign conditions or parathyroid carcinoma, which may show a high ratio of third generation/second generation PTH levels in some patients.
- This study focused on a case of a 60-year-old woman with parathyroid carcinoma and monitored her PTH levels using both assays before and after surgery, revealing significant differences.
- The findings suggest that a high third generation/second generation PTH ratio may indicate parathyroid carcinoma, while normal ratios are typical in patients with benign PHP and osteoporosis, hinting at the need for tailored surgical approaches for those with elevated ratios.
