The subclinical Cushing′s syndrome (SCS) is found in 20% of incidental adrenal tumors (AI). The overnight 1 mg oral dexamethasone suppression test (DST) with the measurement of circulating cortisol (F) is a sensitive method to rule out SCS. The assessment of salivary cortisol (SAF) as a surrogate of F became a non-invasive methodological advance. There are few data on the functional evaluation of AI through SAF in DST (SAFdex). The aim of this retrospective study was to investigate the utility of SAFdex for the detection of SCS in patients with AI. Subjects and Methods: 20 subjects with AI (7 male and 13 women; 65.0 ± 11.0 y/o; BMI: 26.5 ± 1.4) were studied. Sixteen had unilateral and 4 bilateral tumors (size: 10.0 - 90.0 mm; density (UH) was
