Mitotane-induced dyspnoea: an unusual side effect.

Mitotane is a cytostatic antineoplastic agent that is used in the treatment of adrenocortical carcinoma and Cushing's syndrome. The commonly reported side effects associated with mitotane are anorexia, nausea, vomiting, diarrhoea, decreased memory, rash, gynaecomastia, arthralgias and leucopenia. We present a case of a 68-year-old female who developed gradual dyspnoea concurrent with the use of mitotane for the treatment of adrenocortical carcinoma.
