Ectopic Cushing’s syndrome (ECS) associated with malignant tumors, such as small cell lung carcinoma, bronchial carcinoids, and pheochromocytoma, has been reported in human medicine. However, ECS related to pheochromocytoma has not been reported in dogs.

The diagnosis of lung typical carcinoid tumors results challenging when limited size and unfavorable sampling location is associated. It has been reported that bronchoscopy with endobronchial ultrasound (EBUS) significantly increases the diagnostic yield of peripheral nodules smaller than 2 cm.

Paraneoplastic neurological syndromes (PNS) have frequently been described in patients with lung or breast cancer. However, some reports also described a correlation to carcinoid tumors, probably triggered via the excessive release of hormones.

Harrison's Internal Medicine Chapter 96. Paraneoplastic Syndromes: Endocrinologic/Hematologic Paraneoplastic Syndromes: Endocrinologic/Hematologic: Introduction In addition to local tissue invasion and metastasis, neoplastic cells can produce a variety of peptides that that can stimulate hormonal, hematologic, dermatologic, or neurologic responses. Paraneoplastic syndromes refer to the disorders that accompany benign or malignant tumors but are not directly related to mass effects or invasion.

Etiology Vasopressin is an antidiuretic hormone normally produced by the posterior pituitary gland. Ectopic vasopressin production by tumors is a common cause of the syndrome of inappropriate antidiuretic hormone (SIADH), occurring in at least half of patients with SCLC. Compensatory mechanisms, such as decreased thirst, suppression of aldosterone, and production of atrial natriuretic peptide (ANP), may mitigate the development of hyponatremia in patients who produce excessive vasopressin.

Bronchial Adenomas Bronchial adenomas (80% are central) are slow-growing endobronchial lesions; they represent 50% of all benign pulmonary neoplasms. About 80–90% are carcinoids, 10–15% are adenocystic tumors (or cylindromas), and 2–3% are mucoepidermoid tumors. Adenomas present in patients 15–60 years old (average age 45) as endobronchial lesions and are often symptomatic for several years. Patients may have a chronic cough, recurrent hemoptysis, or obstruction with atelectasis, lobar collapse, or pneumonitis and abscess formation.
