Introduction The clinical complex, sarcoidosis, has gradually emerged and enlarged since the descriptions of Hutchinson,1 Besnier,2 Boeck,3 and Schaumann.4 The "concept" of sarcoidosis has been the subject of a great deal of controversy which at the present time is still far from being resolved. The present case offers a perplexing example of the complexity seen in the sarcoidosistuberculosis relationship. Report of Case The patient is a 75-year-old retired white male schoolteacher. He was seen for the first time at the University of Chicago Clinics in December of 1930, at the age of 45. Physical examination at that time was normal with the exception of the chest. Rales were heard posteriorly at both apices, and bilateral narrowing of Krönig's isthmus to percussion was noted. A large chest roentgenogram revealed the presence of lacy shadows extending bilaterally from the hilus to the apices and toward the third interspaces.
