Background

Drug-induced skin pigmentation disorder becomes a common adverse drug reaction, can bring negative effects to physical and mental health of patients, and is easy to cause anxiety and contradict medication. Drug-induced skin pigmentation disorders may manifest as hyperpigmentation or hypopigmentation. Hyperpigmentation is generally due to increased deposition of melanin or non-melanin derived chromophores in the skin caused by drugs, as well as deposition of endogenous or exogenous pigments in the dermis; hypopigmentation is the loss or significant decrease in the number of melanocytes in the basal epidermis layer caused by the drug. Drug-induced skin pigmentation disorders may be temporary or permanent. The variety of drugs that cause skin pigmentation disorders is wide, including antibacterial, antitumor, nervous system and cardiovascular system drugs, etc.

In medical institutions, doctors and pharmacists diagnose skin pigmentation disorders based on medical and pharmaceutical expertise in combination with patient history and clinical characteristics (e.g., pigmentation disorder areas, boundary conditions, line or mesh patterns, etc.), and provide references for patient medication regimen formulation. However, in both clinical and scientific and teaching fields, descriptions of drug-induced skin pigmentation disorders are often subjective and lack uniform, quantitative reference standards, while being susceptible to environmental and individual judgment. In addition, due to the lack of metrics, the degree, progression and prognosis of pigmentation disorders are not accurately described in the existing clinical medical data, and objective evaluation and study of drug-induced skin pigmentation disorders is difficult.
