Adrenocortical neoplasm disguised as a post-traumatic perinephric hematoma

Trauma and cancer are entities that are encountered frequently by surgeons and occasionally may exist simultaneously in certain patients. Illustrated here is the case of a man with a perinephric mass, discovered during evaluation for blunt abdominal trauma, which was originally thought to be a perinephric hematoma and later proved to be an adrenocortical carcinoma.
