Congenital Chevalier Jackson syndrome

Although there are few thousands of rare diseases known to occur in humans, there is often limited professional knowledge, experience and awareness of the manifestations of them and their most appropriate management because of the small number of patients having each one of them. Diagnostic challenges and difficulties, diagnosis delay, and misdiagnoses, inappropriate or unsatisfactory management are well known to be associated with rare diseases. The aim of this book is to describe a prototype of rare disorder "Congenital primary cricopharyngeal achalasia, also called congenital Chevalier Jackson syndrome" which was observed for the first time in Iraqi patient, and its occurrence was associated with diagnostic difficulties before referral to us. The patient received management that can't be considered very satisfactory or very appropriate in the presence of a therapeutic intervention that is considered simple and curative for the disease.
