Clinicopathological analysis of myelolipoma within adrenocortical adenoma / 医学研究生学报

ABSTRACT

Objective At present, there are few studies about myelolipoma within adrenal cortical adenoma.Our aim was to provide more basis for correct diagnosis and treatment by investigation into its clinical and pathological features.Methods The clinical and pathological data were retrospectively reviewed in 11 patients of myelolipoma within adrenal cortical adenoma, along with relative literature reviews.Results The median age of 11 patients (7 females, 4 males) was 49±9.5 years, among whom 3 patients presented Cushing's syndrome, 1 patient with more than 10 years' recurrent dizzy with hypertension, other 7 patients were found coincidently by routine examination.Adrenal mass were found by imaging examination.Pathologically, myelolipomas were in solitary nodule distribution and/or admixed with adrenal cortical adenomas.Myelolipomas were composed of variable admixture of mature adipose tissue and hematopoietic elements.Surgical treatment was performed for all 11 patients, and no relapse was found in 2 months' to 11 years' follow-up.Conclusion Myelolipoma within adrenal cortical adenoma is extremely rare, which is common in females.The patients may present with Cushing's syndrome, hypertension or without obvious clinical syndrome.All the patients are in favorable prognosis after surgical resection.
