ObjectiveTo review and analyse clinical data on the diagnosis and management of patients with adrenal masses.Patients And MethodsPatients admitted with adrenal masses between 1960 and 1995 were reviewed. The series comprised 116 males (mean age 41.4 years, SD 10.5, range 3-77) and 95 females (mean 36.9 years, SD 11.6, range 1-62); eight patients were < 14 years old and the overall mean (SD) age was 39.4 (12.8) years. The diagnosis was based on symptoms, signs, hormone levels and imaging studies. All tumours were confirmed by surgery, and pathology and results of analysis assessed statistically.ResultsOver the last 35 years, the incidence of adrenal tumours was 1.7% of all patients admitted with genitourological diseases or 9.7% of patients with genitourinary tumours at our institution. The prevalence of adrenal tumours in males and females was similar but Cushing's syndrome was 3.1 times more frequent in females than in males and phaeochromocytoma 1.9 times more frequent in males than females. Most patients with adrenal tumour were aged 30-50 years. Of 211 adrenal tumours, 151 (72%) were functional, with a prevalence of benign tumour, and 60 (28%) were nonfunctional, with 35% malignant. There were 78 'incidentalomas' which included 18 functional tumours. Overall, 210 tumours were removed and one was explored. Correlation analysis between tumour size and character or hormone levels showed that size was significantly positively correlated with tumour character (r = 0.4010, P < 0.001), but there was no relationship between tumour size and hormonal levels. The postoperative complication rate was 3.3% and the mortality 0.5%.ConclusionsBased on this analysis we recommend that computed tomography is the first method used to define and localize the adrenal masses, that hormone levels should be determined in symptomatic or asymptomatic patients with adrenal masses, and that functional adrenal tumours and solid incidentalomas of any size should be removed surgically.
