Spectrum of adrenal lesions on fine needle aspiration cytology

Fine needle aspiration (FNA) cytology of adrenal gland is not a commonly performed technique and is limited primarily to tertiary care centers. However, it is a sensitive and specific procedure in the workup of patients with adrenal gland's mass lesions. Though cytomorphological features for various lesions have been described, there are a limited number of studies in cytologic literature.
