Postcricoid hemangioma of childhood: report of four cases.

ABSTRACT

Hemangiomas are the most common tumor of infancy, and the vast majority occur in the head and neck region. In children, laryngeal hemangiomas typically occur below the level of the true vocal folds, in the region of the subglottis, and other sites are exceedingly rare. We present four cases of hemangiomas located in the postcricoid region of the hypopharynx. Because of the location of these lesions, children may present with obstructive symptoms such as dysphagia, intermittent aspiration, hypersalivation, or recurrent respiratory infections. Clinical diagnosis is relatively easily made with flexible laryngoscopy, as the lesions have a propensity to enlarge with crying or straining. When these patients are examined under general anesthesia in a relaxed state, however, the lesions are typically much smaller, and can even go unnoticed. Unlike other reported cases, the postcricoid hemangiomas in our patients were not causing any symptoms and were simply incidental findings. Thus, we believe that the true incidence of postcricoid hemangiomas is likely higher than reports suggest. To our knowledge, we report the longest follow-up (6 years) of a patient with a postcricoid hemangioma and are the first to describe the natural course of such a lesion.
