Tracheal Transplantation.

Airway stenosis and malignant tumors are the 2 main reasons to perform a surgical resection of part of the trachea. Tracheal lesions with a length shorter than 5 cm can be resected and primary reconstruction can be safely effected. Excessive anastomotic tension should be avoided because it may lead to restenosis or dehiscence at the anastomosis.

Molecular analysis using SalvGlandDx improves risk of malignancy estimation and diagnosis of salivary gland cytopathology: An exploratory multicenter study.

Background: Diagnosis of salivary gland neoplasms is challenging, especially on cytological specimens acquired by fine-needle aspiration. The recently implemented standardized Milan system for reporting salivary gland cytopathology provides an estimated risk of malignancy (ROM); yet, for two of the categories, the diagnosis of the lesion remains unclear. However, a precise diagnosis is desirable for optimal patient management, including planning of surgery and imaging procedures.

Molecularly defined sinonasal malignancies: an overview with focus on the current WHO classification and recently described provisional entities.

Classification of tumors of the head and neck has evolved in recent decades including a widespread application of molecular testing in tumors of the sinonasal tract, salivary glands, and soft tissues with a predilection for the head and neck. The availability of new molecular techniques has allowed for the definition of multiple novel tumor types unique to head and neck sites. Moreover, an expanding spectrum of immunohistochemical markers specific to genetic alterations facilitates rapid identification of diagnostic molecular abnormalities.

Malignant carotid body tumors: What we know, what we do, and what we need to achieve. A systematic review of the literature.

Malignant carotid body tumors (MCBT) are rare and diagnosed after detection of nodal or distant metastases. This systematic review (SR) focuses on MCBT initially approached by surgery. Preferred Reporting Items for SR and Meta-Analysis (MA) guided the articles search from 2000 to 2023 on PubMed, Scopus, and Web of Science.
