Enanthema refers to a rash of mucous membranes.
Term used in analogy to the term "exanthema" for localized or disseminated mucosal changes. Mostly occurring in connection with typical and diagnostically groundbreaking skin symptoms triggered by viruses, bacteria or medication; rarely isolated, more often combined with similar symptoms of the conjunctiva and genital mucosa. Correspondingly, macular, purple-hemorrhagic, lichenoid, aphthoid, pemphigoid or ulcerative enanthema are found.
