Laryngeal cancer involving a branchial cleft cyst.

Background: Benign secondary neck lesions in the setting of laryngeal cancer have been described, but not with branchial cleft cysts. This article describes a branchial cleft cyst in a laryngectomy/neck dissection specimen.

Methods And Results: A 44-year-old woman presented to our emergency department with an obstructing laryngeal tumor that was staged as a T4N0M0 squamous cell cancer on the basis of clinical and radiographic findings.

Outcome analysis of patients with squamous cell carcinoma of the head and neck and hepatitis C virus.

Objective/hypothesis: Infection with the hepatitis C virus (HCV) is a global problem with over 170 million people infected. Recently, we have noticed that a large number of patients diagnosed with squamous cell carcinoma of the head and neck (SCCHN) have also been diagnosed with HCV. A review of the literature reveals little information concerning this patient population.

Prevalence and epidemiology of hepatitis C virus in patients with squamous cell carcinoma of the head and neck.

Objective: Recently, we have noticed that a large number of patients with squamous cell carcinoma of the head and neck (SCCHN) are also infected with the hepatitis C virus (HCV). A review of the literature has revealed no published studies examining this association. The objective of this study was to determine the incidence and epidemiology of HCV infection in patients with SCCHN.

Collision tumor of apocrine carcinoma and squamous carcinoma occurring in the ear.

An unusual case of a cutaneous collision tumor comprised of a squamous cell carcinoma and an apocrine carcinoma occurring in the auricle of an 82-year-old man is presented. Microscopic study confirmed 2 distinct tumors: a squamous cell carcinoma arising in the epidermis and an adjacent apocrine carcinoma. We discuss the diagnostic criteria and review pertinent recent literature.
