Abstract

BACKGROUND: Applicability of dermoscopy in evaluation of outcome and monitoring of superficial basal cell carcinoma (sBCC) after nonablative therapies has not been sufficiently assessed.OBJECTIVES: Certain dermoscopic criteria, namely pigmented structures, ulceration and arborizing vessels, have been suggested to predict the presence of residual disease [residual disease-associated dermoscopic criteria (RDADC)]. We aimed to assess this hypothesis.PATIENTS AND METHODS: Lesions exhibiting RDADC 3 months after treatment were biopsied and in the case of histopathological confirmation were excised. Lesions characterized by white/red structureless areas, superficial fine telangiectasias, or lacking any dermoscopic criterion, were monitored for 12 months.RESULTS: At the 3-month evaluation, one or more of the RDADC were detected in 25/98 (25·5%) sBCCs, in which histology confirmed tumour persistence. In 45 (61·6%) of the 73 remaining lesions, dermoscopy showed white/red structureless areas and/or superficial fine telangiectasias. Twenty-eight lacked any dermoscopic criterion of sBCC. The two latter groups entered follow-up. In total, disease recurred in 13 (17·8%) of the 73 lesions.CONCLUSIONS: RDADC accurately predict residual disease. Absence of dermoscopic criteria of sBCC safely predicts complete histopathological clearance. Detection of white/red structureless areas and/or superficial fine telangiectasias warrants close monitoring to recognize early recurrence.
