Chemical inhibition of melanogenesis, disturbance in the transport mechanism of melanosomes, UV absorption in scale deposits.
The so-called pseudoleukoderm does not involve disorders of melanocyte function but simple contrast phenomena which occur as in Psseudoleucoderma psoriaticum due to dithranol staining of the surrounding healthy skin.
