The ‘ultra slow’ BCC Two case studies

Introduction

Most basal cell carcinomas (BCCs) can be diagnosed readily on the basis of a medical history and clinical examination, particularly when various ‘red flags’ are taken into account. The purpose of this article is to show two cases in which BCCs have apparently remained unchanged for over 20 years, masking one of the major indicators of malignancy: change. A general practitioner must maintain a high degree of vigilance so as not to miss those BCCs that behave in an atypical manner.
