Epidermoid Cholesteatoma

Squamous Cell Carcinoma Developing in an Intracranial Epidermoid Cyst (cholesteatoma).

Epidermoid tumour (tumor perlée, cholesteatoma) of the fourth ventricle: case report and review of literature.

The history, clinical course, and the 17 year follow-up after surgery are reported in a patient who had an epidermoid tumour removed from the fourth ventricle. The gross appearance of the contents of the tumour showed multiple tissue aggregates, with the classical pearl-like appearance. Previous cases reported in the literature are collated.

Congenital Intralabyrinthine Cholesteatoma

A patient with a congenital intralabyrinthine cholesteatoma is presented. High-resolution computerized tomographic scans and intraoperative photomicrographs display features of intralabyrinthine extension. We discuss pathogenetic theories for the development of congenital intralabyrinthine cholesteatoma. The distinction of this condition from congenital cholesteatoma with labyrinthine erosion i...

Molecular biology of cholesteatoma.

Cholesteatoma is a non-neoplastic, keratinizing lesion, characterized by the proliferation of epithelium with aberrant micro-architecture into the middle ear and mastoid cavity. The exact pathogenic molecular mechanisms behind the formation and propagation of cholesteatoma remain unclear. Immunohistochemical examinations of the matrix and perimatrix have considerably improved the knowledge of c...

Cholesteatoma - the Silent Killer

Objective-Cholesteatoma has been discussed in all International and National conferences periodically because it is an enigma. The treatment options keep on changing due to sustained recurrence even after perfect surgery. It is a silent killer and therefore is of utmost importance to diagnose and treat this condition early to reduce the mortality and morbidity. Method-In this study we discuss i...
