Endocrine and immunohistochemical studies were performed in a patient with lung cancer associated with gynecomastia. Elevated level of human chorionic gonadotropin (hCG) in plasma and mild hyperadrenocorticism were demonstrated by hormone assays. Postmortem examination proved the existence of anaplastic small cell carcinoma of the lung mixed with a feature of chorioepithelioma. The presence of significant amounts of adrenocorticotropic hormone (ACTH), beta-melanocyte stimulating hormone (beta-MSH), calcitonin, gastrin, hCG, hCG-alpha, hCG-beta and human chorionic somatomammotropin (hCS) in tumor tissues was demonstrated by radioimmunoassays, bioassay and immunohistochemical techniques. We present here a unique case of multiple hormones producing tumor elaborating both hormones of amine precursor uptake and decarboxylation (APUD) series (ACTH, beta-MSH, calcitonin and gastrin) and of placental origin (hCG, hCG-alpha, hCG-beta and hCS).

Tumours of non-endocrine origin may exert deleterious effects by elaborating active principles which disturb body regulation. Systemic manifestations are fairly common with neoplasms of the lung, kidney, gastro-intestinal tract and thymus. The secretion of these tumours may have a known chemical structure (serotonin), may present hormone-like action (parathormone, antidiuretic hormone, insulinoid), or have well-defined biological properties (erythropoietin, gastrin-like principle). Tumours may stimulate endocrine glands by an unknown mechanism, producing disorders such as Cushing's syndrome, hypercalcemia, gynecomastia and hypoglycemia. Thymomas may be associated with autoimmune diseases. Tumours may extensively utilize or excrete some metabolite (glucose) or electrolyte (Na or K). Awareness of the systemic effects of various neoplasms may lead to an early diagnosis and proper treatment of these manifestations.
