AB  - Basal cell carcinomas (BCCs) are slow-growing, locally invasive lesions that rarely metastasise, however, if left untreated can progress to extensive destruction of local structures giving rise to the alternative name ‘the rodent ulcer’. Here we present a case of BCC of the ear progressing to destruction of the pinna and mastoid, involving the facial nerve and breaching dura. This case presentation shows not only the seldom-seen natural progression of the rodent ulcer with impressive imaging and clinical photographs but also highlights a broader topic of capacity and consent in patients displaying maladaptive denial or abnormal illness behaviour, how this can affect patient outcomes and what we as clinicians can do to ensure the best care for our patients.
