Describe the clinical appearances and behavior of the lupus ulcerations.
They are rounded, shallow excavations, with soft and reddish borders. In exceptional instances exuberant granulations appear— lupus hypertrophicus; or papillary outgrowths are noted—lupus verrucosus. The ulcerations secrete a variable amount of pus, usually slight in quantity, which leads to more or less crust formation; later, however, cicatricial tissue, generally of a firm and fibrous character, results.

In what manner does the disease spread?
The patches spread by the appearance of new tubercles, or infiltrations at the peripheral portion. New islets and areas of disease may continue to make their appearance from time to time, usually upon contiguous parts.
Are the mucous membranes of the mouth, throat and larynx ever involved?
In some instances, and either primarily or secondarily.
