An 85-year-old woman with a history of hypertension and diabetes mellitus was referred to the Dermatology Outpatient Clinic of the Complejo Hospitalario de Granada, Granada, Spain, in 2016 with an excrescent tumour on her upper forehead measuring 8 mm in diameter that had been present for the past two years. She had been exposed to significant ultraviolet (UV) radiation and undergone excision of two basal cell carcinomas (BCCs) 10 years prior. Upon physical examination, the lymph nodes were not palpable and there was no evid-ence of hepatosplenomegaly. In CCS cases, Mohs micrographic surgery is the treatment of choice and has been reported to result in a cure rate of ≥98%; in contrast, a recurrence rate of 33% has been reported without this surgery. As such, close observation of the patient is required if Mohs surgery is not performed. There is no evidence to support the use of adjuvant radiotherapy. The prev-alence of metastasis in CCS with a basal cell epith-elial component has been reported in 2% of cases.
