Talc-induced lung disease comprises of a group of pathologies that can occur due to exposure to the mineral talc (hydrated magnesium silicate).
Four types of pulmonary disease secondary to talc exposure have been defined. These are:
talcosilicosis: associated with occupational exposure
talcoasbestosis: associated with occupational exposure
talcosis: associated with inhalation of pure talc
pulmonary talc granulomatosis: occurs in the setting of people with substance use disorder who inject tablets intended for oral use (related to talc pulmonary embolism)
