Self-healing Hypernephromas

Abstract

While studying the phenomenon of spontaneous regression in epidermal cancer, our attention was drawn to Hultquist’s findings on self-healing hypernephromas. The present report is based on autopsy material collected from a small hospital over a two-year period and emphasizes the common occurrence of spontaneous regression of cortical renal cancers, particularly of the clear-cell variety. These lesions may impress as banal scars. Five tumors, some of which were multiple, are reported.
