Abstract

Background: Melanocytic tumours which colonise basal cell carcinomas (BCC) may be considered as either lentigo maligna (LM) (in situ) or invasive melanomas. Objectives: To highlight the diagnostic approach and long-term prognosis of LM which colonises BCC. Materials and methods: Using Satter et al.’s classification, we identified a case of BCC colonised by LM and reviewed similar cases in the literature with longterm follow-up. Results: In the absence of melanocytic extension beyond the lamina propria of theBCCcompartment, mixed tumours may be considered as LM colonising the BCC, allowing for less invasive surgery. The absence of long-term relapse in our short series supports this diagnosis, rather than invasive melanomas. Conclusion: Our case report, review of the literature, and series follow-up illustrate the most recent assessment of melanocytic/BCC tumours, and guide the physician and the pathologist in their recognition and classification, thus allowing them to make the most appropriate therapeutic decisions.
