Dermoscopy, reflectance confocal microscopy and histopathology of a melanoma in situ from an individual homozygous for GSTP1∗105Val/MC1R∗92Met

Abstract

Glutathione S-transferase 1 is an enzyme involved in the detoxification of reactive oxygen species, and the rs1695∗Val polymorphism has been proposed as a melanoma-associated variant with significant effect. We report a case of malignant melanoma in an individual homozygous for the rs1695∗Val variant and discuss the non-invasive and histopathological tools used in diagnosis.
