The etiology of sarcoidosis (lymphogranulomatosis benigna, Besnier-Boeck-Schaumann disease, sarcoid of Boeck, lupus pernio), granuloma annulare and lupus erythematosus is still undetermined. The discussion usually centers around the following possibilities: (1) a specific disease, caused by (a) Mycobacterium tuberculosis, (b) another specific micro-organism or (c) an unknown organism or virus, and (2) a syndrome or cutaneous reaction caused by any of a multiplicity of agents.
The association of these diseases with general tuberculosis has been used in defending as well as in refuting the possibility of a tuberculous origin. Therefore, it seems justified to report a statistical study of the incidence of tuberculosis of the lungs with these conditions.
The statistics presented are based on the records of the radiologic department of the university dermatologic clinic at Breslau, Germany (directors, Prof. J. Jadassohn and Prof. M. Jessner), from 1925 to 1934.The statistics concerning sarcoidosis, granuloma annulare and lupus erythematosus
