Mucus extravasation phenomenon in newborn babies: report of two cases

Two rare cases of congenital mucoceles in newborn babies are reported. The patients presented with nodular swellings on their lower lips at birth with no obvious local aetiology. In both cases the mucoceles interfered with normal feeding. The lesions were excised by surgical approach under general anaesthesia and histopathological examination confirmed the lesions to be extravasation-type mucoceles. The article includes a brief discussion of the epidemiology and ethiopathogeny of mucoceles.
