Prognosis

The prognosis of the disease is, to a certain extent, favourable, but depends largely on the degree of development, particularly if it has not yet become atro-phic. In this latter condition the lesions are lasting; but in its earlier stage, and especially when there is only moderate hypertrophic change in the connective tissue, there is a tendency to spontaneous disappearance.

Its course of development, when mainly hypertrophic, is quite short, as compared with the period elapsed during the atrophic stage, which is usually slow and chronic, extending over several years.
