Although the management of benign pigmented skintumors are mainly conducted by dermatologists, some Korean traditional doctors provide care. We aimed to evaluate the appropriateness of the medicinal knowledge of pigmented benign skintumors that is recorded in the Korean traditional medicinal literature, in the context of modern medicine. We defined benign pigmented skintumors as macules, papules, or nodules with homogeneous surfaces and coloration patterns, that are round or oval in shape, exhibit regular outlines, and have relatively sharp borders. We investigated textbooks and articles in the Korean traditional medicinal field to analyze descriptions of clinical classification, pathophysiology, histologic knowledge, and treatmentmethod. We compared them with modern medicinal facts. In Korean traditional medicine, clinical classification of pigmented skintumors is simple and did not include histologic natures. Unique theories, such as Yin-Yang and Qi, were applied to pathophysiologic understanding of these diseases. Interestingly, oral medications were used beside surgical methods. We could not find any comment about skintumors with worrisome clinical features that warrant excision in Korean traditional medicinal literature. There is still a gap between traditional medicine and modern medicine regarding pigmented skintumors. Traditional Korean medicinal knowledge about benign pigmented skintumors seemed to be insufficient in the context of modern medicinal standards.
