Two cases of androgen secreting adrenocortical carcinoma have been described by light and electron microscopy. The histological and ultrastructural features of the tumour cells were similar to those of compact cells of zona reticularis and to those described in virilizing adenomas. They possess numerous mitochondria with lamellar and tubular cristae, abundant smooth endoplasmic reticulum, lipofuscin bodies and scanty lipid. Irregularly shaped, crenated mitochondria, with outpouchings of the outer limiting membrane have also been observed. The clusters of neoplastic cells were surrounded by basement membrane which demonstrated a focal discontinuity, probably reflecting malignancy of the tumours. Hyperplasia of smooth endoplasmic reticulum and the presence of outpouchings of the mitochondrial outer limiting membrane might be the morphological manifestation of endocrine activity of the tumours.

Major endocrine ablation therapy was carried out in 133 patients with advanced breast cancer. Of 40 patients undergoing left suprarenal to inferior mesenteric venous shunt with bilateral oophorectomy and right adrenalectomy, 16 cases (40 per cent) had an objective response. The mean postoperative survival of the patients with a positive response, those showing some response and those who failed to respond was 35-8, 26-5 and 8-8 months respectively. Thus, the results of the present procedure are comparable to those of adrenalectomy. No replacement therapy with corticoids was necessary. An increase in the response rate and extension of the survival time can be expected with the addition of postoperative long term maintenance therapy with chemotherapeutic agents and androgens.

The second fully documented case of ACTH-producing prostatic adenocarcinoma with elevated plasma and tissue levels of ACTH is presented. The distinguishing characteristics of ACTH-producing extrapituitary neoplasms and the various modes of therapy are discussed.

Mouse lymphoma cells in culture which are killed by adrenal steroids contain specific cortisol receptors that may be involved in the initial events of hormone action. The similarity of these receptors to those in hepatoma tissue culture cells, where adrenal steroids induce tyrosine aminotransferase, suggests that certain aspects of steroid action are similar in the two systems. In three steroid-resistant lymphoma cell populations specific binding was less than in the parent lines, suggesting that conversion to steroid resistance may be associated with changes in specific steroid binding.
