Adrenocortical carcinomas are rare but aggressive tumors that are frequently discovered as incidentalomas. Secretory tumors often lead to endocrine abnormalities, namely cushingoid features, virilization, or feminization. Non-functioning tumors, on the other hand, can be completely dormant with an insidious course or cause malaise, weight loss, abdominal pain, etc.

Alveolar epithelial type I (AE1) cells with their wide spatial expansion form approximately 95% of the outer surface area of the air-blood barrier inside the lung. Serial block-face scanning electron microscopy (SBF-SEM) investigations led to the hypothesis that AE1 cell mitochondria are preferentially distributed as aggregates in those parts of AE1 cells that are located above connective tissue pillars between capillaries, thus not increasing the thickness of the diffusion distance for oxygen and carbon dioxide. Furthermore, it was hypothesised that postnatal development requires adapting the amount and distribution of mitochondria in AE1 cells.
