Localization of basic fibroblast growth factor in cholesteatoma matrix; an immunochemical study
Abstract: Objectives; to investigate the expression of b-FGF in the matrix of human acquired cholesteatoma compared to the deep meatal skin. To our knowledge, this topic has not been fully investigated before. Materials and methods; an immunochemical study was employed. Cholesteatoma tissues from adult patients were collected during surgery (n=19). Control specimens were taken from the deep meatal skin (n=8) ... Read more

Case report of congenital cholesteatoma in the oval window and posterior mesotympanum surrounding a dehiscent fallopian canal in a young adult
Congenital cholesteatoma is defined as cholesteatoma occurring behind an intact tympanic membrane (TM). In the middle ear, it has different stages according to its site and relation with surrounding structures. We report an unusual case which is congenital cholesteatoma in the oval window and posterior mesotympanum surrounding a dehiscent fallopian canal in a young adult without obvious lesion behind intact ...

Cytokeratin 13, Cytokeratin 17, and Ki-67 Expression in Human Acquired Cholesteatoma and Their Correlation with Its Destructive Capacity
OBJECTIVES Cholesteatoma is a nonneoplastic destructive lesion of the temporal bone with debated pathogenesis and bone resorptive mechanism. Both molecular and cellular events chiefly master its activity. Continued research is necessary to clarify factors related to its aggressiveness. We aimed to investigate the expression of Ki-67, cytokeratin 13 (CK13) and cytokeratin 17 (CK17) in acquired nonrecurrent human cholesteatoma and correlate ... Read more

Expression of basic Fibroblast Growth Factor in acquired cholesteatoma and correlation with its destructive capacity
INTRODUCTION: Angiogenesis is an essential requirement for cholesteatoma growth and expansion. It is mediated via variety of cytokines and growth factors like basic fibroblast growth factor (basic-FGF). Localization of basic FGF in cholesteatoma matrix and its correlation with the destructive capacity of cholesteatoma were seldom seen in previous reports. METHODOLOGY: A prospective immunohistochemical study was employed using 19 acquired cholesteatoma ... Read more
