Acanthoma fissuratum--spectacle frame acanthoma.

The development of a cutaneous nodule at the site of friction of spectacles has been discussed by several authors. In all but one case the lesion occurred behind the ears. The only previous report of this acquired tumour occurring on the nose is that of Farrell & Wilson (4). It is suggested that this problem is relatively common and most frequently presents when mistaken for basal cell epithelioma or when identified in medical personnel. A further six cases of this neglected tumour occurring on the nose are described.
