E-mail: [email protected] A 28-year-old woman presented with a painless tumour on her upper lip (Fig. 1). She had no medical history and used no medications. The tumour had been present since early childhood and had so far been considered benign. Over the last 5 years the tumour had grown slowly, and therefore the patient was referred for dermatological evaluation. On exa- mination, the tumour was 1.5 cm in diameter, well-defined, circular, with marked induration, and non-adherent to the surroundings. The skin covering the tumour was unremark­ able apart from mild redness and minor telangiectasia at the periphery. The patient was otherwise asymptomatic and had no palpable lymph nodes.
