title: Double tumors of anterior and posterior pituitary gland.
abstract: Double tumors were found in the anterior and posterior lobes of pituitary gland at autopsy in a patient who presented with progressive deterioration of mental status. The chromophobe adenoma of anterior lobe consisted of a mixture of non-immunoreactive hormone containing cells and a few prolactin (PRL) and growth hormone (GH) cells in the mid portion whereas the periphery of the tumor contained immunoreactive cells for PRL, GH, thyroid-stimulating hormone (TSH), luteinizing hormone (LH), and follicle-stimulating hormone (FSH). A microscopic focus of granular cell myoblastoma (GCM) was found in the posterior lobe. Differentiation of tumor cells into anterior pituitary cells and GCM is discussed.
