Granulomatous papular rosacea may be found on both medial and lateral facial areas and it may appear on diascopy as yellow-brown nodules and on histologic examination as noncaseating epithelioid cell granulomas which may resemble sarcoidosis, tuberculosis, or other granulomatous diseases. Patients presenting these features should not be considered to have tuberculids, and antituberculous therapy is not indicated unless, of course, an active site of tuberculosis is actually identified. Beneficial results have been obtained in these cases with Danish ointment (betanaphthol, sublimed sulfur, Peruvian balsam, and petrolatum) along with or without the topical use of steroids or systemic use of tetracycline or both.
