Optical coherence tomography imaging of basal cell carcinoma undergoing photodynamic therapy: A pilot study

- The conversion of hyporeflective basal cell carcinoma nodules into hyperreflective ovoid structures was remarked with optical coherence tomography (OCT) as a sign of tumor regression under photodynamic therapy (PDT).
- OCT presented a higher accuracy in identifying residual and non-residual lesions after PDT treatment compared to clinical inspection alone.
- OCT might be used in the future as a standard procedure for detecting non-melanoma skin cancer sparing patients invasive procedures.
