Adrenal cortical carcinoma initially presented with overwhelming disseminated intravascular coagulation.

We report a 54-year-old man who had adrenal cortical carcinoma initially manifested as features of overwhelming disseminated intravascular coagulation (DIC). In the initial diagnostic work-up, an adrenal mass was detected with venous thrombi in the abdominal imaging study, but the radiologic diagnosis was a hematoma arising from the adrenal gland and a biopsy was not possible due to a bleeding tendency. A lot of platelets and plasma products were transfused, but the bleeding tendency and other DIC features persisted. Finally, he expired because of newly developed massive pulmonary thromboembolism. To our knowledge, this is the first reported case of adrenal cortical carcinoma complicated with bleeding tendency caused by DIC as an initial manifestation. This suggests that adrenal cortical carcinoma should be considered in a patient with an adrenal mass and DIC features.
