[Adrenocortical cancer: late diagnosis of the disease on the example of a clinical case. Case report].

Adrenocortical carcinoma (ACC) is a rare malignant tumor originating in the adrenal cortex and characterized by poor 5-year survival. It occurs with a frequency of 2-4 cases per 2 million in the population. Women are more frequently affected than men and it is mostly detected in the fourth and fifth decades. In the most of cases, the cancerogenesis occurs sporadically because of gene driver mutations in somatic adrenocortical cells, in other cases it can be found as part of a genetically determined syndrome such as Li-Fraumeni syndrome or Wermer's syndrome (multiple endocrine adenomatosis type I). ACC most frequently happens occurs without symptoms in the initial stages leading to poor diagnoses. Because of this lack of early detection, the tumor is not considered malignant reducing the benefits of further treatment. Sometimes the fact that the resected tumor is indeed adrenocortical carcinoma becomes clear only after recurrence, or after the appearance of metastases. We present a case of adrenocortical carcinoma in a 46-year-old woman who went to the doctor in 1.5 year after symptoms were manfested. This clinical case illustrates the consequences of late diagnosis of a malignant tumor. We would like to emphasize the importance of timely detection of a neoplasm, using all of the potential of laboratory-instrumental and genomic analysis. Due to low oncological awareness, our patient was slow to seek medical help, which in turn led not only to metastases, but also to complications in the cardiovascular system.
