[The clinical entity of primary tracheal cylindroma (author's transl)].

: On the grounds of 5 own observations of primary tracheal cylindroma and under consideration of the cases mentioned in literature on this subject, the repeatingly occurring and, therefore, probably typical characteristics of this kind of tumour were described. In the course of the disease, three phases may quite easily be differentiated, and the special features of the main symptoms (dyspnoea, cough, expectoration, hoarseness) as well as apparently specific, however inconstant changes in the blood picture were set forth.
