Phototherapy of cutaneous T-cell lymphomas
Cutaneous T-cell lymphomas (CTCL) are a heterogenous group of non-Hodgkin lymphomas arising in the skin. Phototherapy with ultraviolet radiation, introduced in 1976, is still a mainstay of treatment. Depending on CTCL variant and stage psoralen and ultraviolet A, narrow-band ultraviolet B, or photopheresis are used and can provide effective palliation for many patients.

Mechanistic considerations on the wavelength-dependent variations of UVR genotoxicity and mutagenesis in skin: the discrimination of UVA-signature from UV-signature mutation
Based on the polη-dependent TLS across deaminated CPDs, the wavelength dependence of UVR mutations can be explained by different photochemistries of CPD formation, the singlet/triplet and collective excitations that cause UV-signature and UVA-signature mutations, respectively.
