Molecular defects in BRAF wild-type ameloblastomas and craniopharyngiomas—differences in mutation profiles in epithelial-derived oropharyngeal neoplasms

Virchows Archiv, 2018
The aim of this study was to evaluate the mutation profile of BRAF wild-type craniopharyngiomas and ameloblastomas. Pre-screening by immunohistochemistry and pyrosequencing for identifying BRAF wild-type tumors was performed on archived specimens of ameloblastic tumors (n = 20) and craniopharyngiomas (n = 62).

Oropharyngeal Mixed Neuroendocrine-Nonneuroendocrine Neoplasm (MiNEN): A Case Report and Literature Review

Head and Neck Pathology, 2021
Primary mixed neuroendocrine-nonneuroendocrine neoplasm (MiNEN) of the head and neck region is a rare biphasic tumor with an aggressive biological behavior. This report highlights an additional case of oropharyngeal MiNEN in a 46-year-old male patient with a previous long-term smoking history.

Association of human papillomavirus (HPV) infection with the occurrence of second neoplasms and their prognostic impact in patients with oropharyngeal carcinoma.

Acta Otorrinolaringologica (English Edition)
This study analyzes the incidence of second neoplasms in patients with oropharyngeal carcinoma according to human papillomavirus (HPV) status and its impact on survival.A retrospective analysis of 583 patients with oropharyngeal cancer treated between 1991 and 2023 was performed. A total of 112 patients (19.2%) had HPV-positive tumors.During the follow-

Oropharyngeal Mixed Neuroendocrine-Nonneuroendocrine Neoplasm (MiNEN): A Case Report and Literature Review

Head and Neck Pathology
Mixed neuroendocrine-nonneuroendocrine (MiNEN) neoplasms in the head and neck are exceptionally rare biphasic tumors with unclear pathogenesis and an aggressive clinical behavior. This is the first reported case of an oropharyngeal MiNEN with the nonneuroendocrine component being an HPV-associated adenocarcinoma.
