Slide Tracheoplasty for Tracheal Cartilaginous Sleeve in a Patient With Apert Syndrome.

Apert syndrome is a form of acrocephalosyndactyly involving craniosynostosis, syndactyly, and less commonly, tracheal cartilaginous sleeve (TCS), a potential cause of tracheal stenosis. Slide tracheoplasty is performed in children with tracheal stenosis. No reports exist for its application in stenosis related to TCS.

Head and neck paragangliomas: A two-decade institutional experience and algorithm for management.

Objectives: Paragangliomas of the head and neck and cranial base are typically benign, slow-growing tumors arising within the jugular foramen, middle ear, carotid bifurcation, or vagus nerve proper. The objective of this study was to provide a comprehensive characterization of our institutional experience with clinical management of these tumors and posit an algorithm for diagnostic evaluation and treatment.

Methods: This was a retrospective cohort study of patients undergoing treatment for paragangliomas of the head and neck and cranial base at our institution from 2000-2017.

Epigenetic alterations in metastatic cutaneous carcinoma.

Background: Squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) are the 2 most common cutaneous carcinomas. Molecular profiles predicting metastasis of these cancers have not been identified.

Methods: Epigenetic profiles of 37 primary cases of cutaneous SCC and BCC were quantified via the Illumina Goldengate Cancer Panel.

Cancer stem cells: mediators of tumorigenesis and metastasis in head and neck squamous cell carcinoma.

Background: Cancer stem cells (CSCs) represent a subpopulation of cells responsible for tumor growth. Their role in head and neck squamous cell carcinoma (HNSCC) tumorigenesis and metastasis remains uncertain.

Methods: Wound healing and an orthotopic animal model were used to study cells expressing the CSC phenotype (CD44(high) and aldehyde dehydrogenase [ALDH](+)) and assess mobility, tumorigenesis, and metastasis.

The role of head and neck squamous cell carcinoma cancer stem cells in tumorigenesis, metastasis, and treatment failure.

Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer worldwide. Despite advances in diagnostic and therapeutic methods, survival of HNSCC remains unchanged over the last 30 years with treatment failure and metastases being the strongest indicators of poor outcome. Cancer stem cells (CSC) have been identified in multiple other solid tumors, including breast, prostate, and pancreatic carcinoma.
