Cancer of the hilus.—Primary cancer of the lung mayin certain cases begin in the region of the hilus. In the onlycase which Barj on observed a congenital malformation ofthe lung existed. The left lung, in place of being dividedby a normal interlobar fissure into two lobes, upper andlower was divided by a longitudinal fissure into a short andlimited hilus lobe and a large longitudinal lobe occupying.

This last was absolutelynormal and the cancer remained limited to the hilus case, then, comes into the category of lobar cancer. Often cancer of the hilus region is secondary to tumors ofthe surrounding part—cancer of the mediastinum—and be-longs then in the following class: 2. Secondary cancer.—This may appear under two forms:a nodular form which is quite characteristic from a radio-logical point of view, and a diffuse form, the radiologicaldiagnosis of which is much more difficult. a.
