Metastases to the Parathyroid Glands: A Comprehensive Literature Review of 127 Reported Cases.

Metastases to the head and neck organs are uncommon, potentially representing the initial presentation of an occult malignancy. Single case reports and small series report metastases to the parathyroid gland, but there is no large review of the literature on secondary tumors involving the parathyroid glands. A review of the English literature between 1950 and 2017 was performed of all metastases or secondary involvement of the parathyroid glands.

Treatment of the Chronic Type B Aortic Dissection: The Pro-endovascular Argument.

Although thoracic endovascular aortic repair (TEVAR) is the standard of care in acute complicated type B dissections, its role in chronic type B dissections remains controversial. This controversy stems from anatomical differences between acute and chronic dissections, such as a thicker intimal clap and improved results in descending aortic replacement. However, despite these important differences, there has been accumulating evidence on the safety and efficacy of TEVAR in chronic type B aortic dissections, especially when considering the alternative of open surgical repair, which is associated with significantly higher morbidity and in many hands also higher mortality.

Sinonasal tract adenoid cystic carcinoma ex-pleomorphic adenoma: a clinicopathologic and immunophenotypic study of 9 cases combined with a comprehensive review of the literature.

Primary sinonasal tract carcinoma ex-pleomorphic adenoma (CEPA) is very uncommon, with adenoid cystic carcinoma (ACC) CEPA exceptional. These tumors are often misclassified. This is a retrospective study.
