RESUMO
Adrenal gland incidentaloma (incidental - sudden, accidental) is a mass of the adrenal gland(s), accidentally detected by an instru-mental examination conducted for other reasons. The frequency of detection of this pathology based on computer tomography of the abdominal organs is 0.5%-2%. In most cases, the mass is represented by adrenocortical adenomas without hormonal secretion. It is an extremely rare case (less than 1% of all cases) when the adrenal incidentaloma is a primary adrenal lymphoma, which accounts for 1% of all non-Hodgkin lymphomas and 3% of all extranodal lymphomas with a few cases reported in the literature. In our article, we present a case of left adrenal incidentaloma of the adrenal gland, which, during further observation and examination, increased in size, which was the reason for performing laparoscopic adrenalectomy. According to the results of the histological examination, the mass turned out to be diffuse large B-cell lymphoma.
