Successful Treatment to Dermatitis Papillaris Capilliti (Kaposi) with Kampo (Japanese Traditional Herbal Medicine) Formulations

We report a case of dermatitis papillaris capilliti (DPC) that was successfully treated with Kampo (Japanese traditional herbal medicine) formulations (Keigai-rengyo-to and Keishi-bukuryo-gan). A 38-year-old man presented with longstanding-therapy resistant papillomatous lesions on the occipital area and nape for 15 years. Diagnosis was made as DPC. He had also cystic acne. Histopathological findings revealed follicular hyperkeratosis in the infundibulum and fibrosis in the dermis. After Kampo formulations (Keigai-rengyo-to and Keishi-bukuryo-gan) were administered, inflamed and granulomatous lesions subsided remarkably. The successful treatment with these herbal formulations shows Kampo therapy can acts as an alternative treatment for DPC.
