title: [Syringocystadenoma papilliferum as a differential diagnosis of a carcinoma of the lower lip].
abstract: A 56-year-old patient showed a skin-colored tumor of the lower lip which had been photographically documented since his 10th year of age. On account of the localisation, increase of size during the last few months, as well as irregular epithelial hyperplasia observed in a punch biopsy from the periphery, we suspected the tumor to be a squamous cell carcinoma. Histological examination, however, revealed syringocystadenoma papilliferum.
