Clonal dominance of CD133+ subset population as risk factor in tumor progression and disease recurrence of human cutaneous melanoma.

Chemotherapeutic refractoriness of advanced cutaneous melanoma may be linked with melanoma-initiating cells, also known as melanoma stem cells. This study aimed to determine relative risk of clonal dominance of the CD133+ phenotype in tissues from melanoma patients with different clinical outcomes that could be applied to early diagnosis, prognosis or disease monitoring. Significant overexpression of CD133 (p<0.

Neck management in patients undergoing postradiotherapy salvage laryngeal surgery for recurrent/persistent laryngeal cancer.

Objective: To determine a plan for the management of cervical lymph nodes in patients undergoing salvage laryngeal surgery (SLS) for recurrent/persistent laryngeal cancer after primary radiotherapy (RT).

Study Design: : Retrospective chart review.

Methods: Charts of 51 consecutive patients who had salvage total or supracricoid laryngectomy with or without neck dissection for recurrent/persistent laryngeal squamous cell carcinoma after primary RT from 1988 to 2005 in our institution were reviewed.

Combined surgical and endovascular treatment of a spontaneous diploic arteriovenous fistula. Case report.

The authors report on the case of a 28-year-old woman presenting with an intraosseous arteriovenous fistula (AVF) located in the left parietal bone. The fistula was formed by direct arteriovenous shunts connecting branches of the left middle meningeal and superficial temporal arteries with a parietal diploic vein. Drainage occurred through both the external and internal jugular venous systems.

Atypia in inverted urothelial papillomas: pathology and prognostic significance.

Inverted papillomas of the bladder are considered benign urothelial neoplasms, based on their histology and clinical course. There are scant data on inverted papillomas with atypical features. Whether to designate them as inverted papillomas with atypia or low-grade transitional cell carcinomas with inverted features is controversial.
