Eighteen patients with Cushing's disease were treated with reserpine and pituitary irradiation. Complete remission was obtained in 9 out of 18 patients after reserpine treatment of 1-2 mg per day for a mean period of 20.4 months, and pituitary irradiation with a mean of 5,865 rads. In another 9 patients, reserpine 0.8-2 mg per day for a mean period of 22.5 months, and pituitary irradiation with a mean of 6,650 rads, were employed. Of these 9 patients, an additional subtotal adrenalectomy was carried out in 6 patients who are now in complete remission. Because of severe psychic symptoms resulted from the original disease in 2 of the remaining 3 patients, subtotal adrenalectomy was performed first and pituitary irradiation and reserpine treatment followed. Remission was eventually obtained in these 2 cases. One patient refused the operation, and thus had little clinical remission. All of the 17 cases in remission were followed up for periods of 6 months to 10 yr. During this time, only one case which had responded to reserpine and pituitary irradiation relapsed, but regained remission following resumption of therapy. Another died of cerebral glioblastoma 4 yr after remission of the disease. It was noteworthy that endocrinologic data including: plasma levels of ACTH and 11-OHCS, suppressibility by dexamethasone, responses of plasma GH to arginine and to insulin loads, and diurnal rhythm of plasma 11-OHCS were nearly normal in a considerable number of the cases in remission. Effectiveness of the combined therapy with reserpine and pituitary irradiation for treating Cushing's disease may support a working hypothesis that reserpine acts through some as yet unknown mechanism to correct a presumed central nervous disorder, while suitable pituitary irradiation probably corrects the pituitary dysfunction directly.

Pituitary carcinoma is defined as a malignant pituitary tumour associated with blood- or lymph-borne metastases. Cushing's disease is frequently present in patients with this condition. After adrenalectomy for Cushing's disease, a 37-year-old man developed Nelson's syndrome resulting from a pituitary carcinoma with metastases to the spinal cord, cauda equina, heart, liver, and pancreas. The primary tumour and its metastases showed immunocytochemical staining for ACTH, beta-lipotrophin, and variably for beta-endorphin and alpha-melanocyte stimulating hormone (alpha-MSH). A coincidental glioblastoma was also present. Nine cases of Cushing's disease associated with pituitary carcinoma, including the present patient, are documented in the literature. The case reported is only the second in which immunohistochemical staining of the primary pituitary tumour and its metastases was performed, and the first in which ACTH-related peptides, in addition to ACTH itself, were demonstrated in the carcinoma cells.
