The production of adrenocorticotropic hormone by non-pituitary carcinomas has been documented in several tumors, most frequently small cell carcinoma of the lung, islet cell carcinomas of the pancreas, thymomas and carcinoids. Electron microscopy of these tumors reveals typical membrane-limited "neurosecretory" granules. Confirmation of the granules as adrenocorticotropin (ACTH) requires the use of OsO4 as a primary fixative to give the characteristic cored granule appearance in conjunction with immunohistochemical demonstration of the hormone peptide. Because of the rarity of ectopic ACTH production by mammary carcinomas and the absence of appropriate ultrastructural studies in the two examples of such ectopic hormone production in the literature of which we are aware (1,2), we present biochemical and ultrastructural data from a carcinoma of the breast with apparent ACTH production.The patient had her primary tumor in the right breast in 1969. The tumor recurred as visceral and subcutaneous metastases in 1976 and again in 1977.

The paper describes a clinical example of the topical diagnosis of adrenocorticotropic hormone (ACTH)-producing typical peripheral pulmonary carcinoid. The first stage in its diagnosis was to rule out the production of ACTH by the pituitary gland. The paper presents information on the most common localization of functioning neuroendocrine tumors, as well as a diagnostic algorithm to search for an ectopic focus of the ACTH-secreting tumor that causes hypercorticism. Taking into account that bronchopulmonary neuroendocrine tumors with ectopic hormone production occur rarely (5%), a clinical example is given to demonstrate the capabilities of imaging techniques and standards for their implementation using an integrated approach.

Immunohistochemistry with antibodies targeting enzymes responsible for the final conversion steps of cortisol (CYP11B1) and aldosterone (CYP11B2) is gaining ground as an adjunct tool in the postoperative evaluation of adrenocortical nodules. The method allows the pathologist to visualize hormone production for each lesion, thereby permitting a more exact assessment regarding the distinction between adrenocortical adenomas and adrenocortical hyperplasia, with implications for patient follow-up. We describe how immunohistochemistry facilitated the histopathological diagnosis of twin adenoma (one cortisol- and one aldosterone-producing) from suspected hyperplasia in a patient with hypertension, mild autonomous cortisol secretion and concurrent adrenocorticotropic hormone–producing adrenomedullary hyperplasia. As the nodules were similar in size and displayed rather analogous histology, CYP11B1 and B2 immunohistochemistry was needed to exclude adrenocortical hyperplasia, allowing us to discharge the patient from further surveillance. We conclude that the application of functional immunohistochemistry has direct clinical consequences and advocates the prompt introduction of these markers in clinical routine.
