The lesion is a 'rodent ulcer' i.e. an ulcerated nodular basal cell carcinoma.

The lesion should be fully excised by an experienced skin surgeon with a margin of several millimetres. Although primary closure may be possible in this patient, reconstruction may require a flap or skin graft.

The patient's skin should be fully examined, as there is a high chance he will have more than one significant skin lesion. He may have other basal cell carcinomas, solar keratoses, squamous cell carcinomas or perhaps a melanoma. The patient should be advised regarding sun protection, self skin examination and the need to return to his medical practitioner should he develop any further skin lumps or sores.
