Oncocytoma of the adrenal gland in Birt-Hogg-Dube syndrome.

A 32-year-old man was referred to our surgical unit with a left adrenal lesion. He was previously diagnosed with Birt-Hogg-Dube syndrome after presenting with a left pneumothorax and an incidental finding of a right apical lung mass. This syndrome is characterised commonly by benign skin hamartomas, recurrent pneumothoraces and an increased risk of renal tumours. He was unable to tolerate a biopsy of his lung lesion, however, this lung lesion was thought to be benign. Given the size of his adrenal lesion and radiological appearances, we performed a laparoscopic left adrenalectomy. Pathology confirmed that based on morphological appearances and immunohistochemical staining, this may represent an oncocytic tumour of the adrenal gland. This is only the third published case of an oncocytic tumour of the adrenal gland in a patient with Birt-Hogg-Dube syndrome.
