Sucking blister in a newborn: atypical localisation.

Abstract

A meticulous examination of the oral cavity is an essential part of the initial newborn assessment. The differential diagnosis can involve benign and self-limiting lesions to those lesions compromising quality of life. We present a clinical case of a newborn born with a purple, hard tumour on the hard palate that spontaneously regressed, being thus compatible with the case of a sucking blister. Neonatal sucking blisters typically result from vigorous sucking in utero, most commonly of the hand or forearm; however, more atypical locations may be involved. These benign blisters should be differentiated from other newborn conditions by their presentation, characteristic morphology and self-limiting course. A high index of clinical suspicion is necessary to avoid unnecessary investigations and treatments.
