A 4-month-old male Siberian Husky dog had a history of coughing, high fever and anorexia. Thoracic radiographs revealed increased radiographic density in the cranial and middle lobes of the right lung, with pleural effusion. Cytological examination of the pleural fluid suggested carcinomatous pleuritis. Right-side thoracotomy and resection of the cranial and middle lobes were performed. Histopathological examination of the resected tissue revealed an anaplastic large cell carcinoma. The tumour cells were positive for neuron specific enolase and also contained neuroendocrine granules. A particularly unusual feature of this case of pulmonary neuroendocrine carcinoma was the young age of the affected animal.

Neuroendocrine carcinoma of the nasopharynx was diagnosed in a 9-year-old male Golden Retriever. The mass was identified by computed tomography of the nasal cavity and nasopharyngoscopy, and it was surgically excised. Histologic, cytochemical, and electromicroscopic examination of specimens confirmed the type of tumor. The dog was clincally improved for 150 days but was then reexamined because of respiratory difficulty and poor appetite. Thoracic radiographs revealed multiple nodules in all lung lobes, and ultrasonography revealed a mass in the spleen. The dog died the next day.

Ectopic ACTH syndrome is a rare disease often associated with severe hypercortisolism. When feasible, optimal management is surgical excision of the tumor. A 33-year-old male patient was admitted to the hospital in 1993 with clinical manifestations suggestive of Cushing's syndrome. He presented high plasma ACTH and markedly elevated urinary free cortisol excretion that was not suppressed with high-dose dexamethasone administration. Pituitary MRI scan was normal. No central-to-peripheral ACTH gradient was present in bilateral inferior petrosal sinus sampling. Thoracic CT scan showed a 1.7 cm nodule at the left lung. Pulmonary fine needle cytology and immunocytochemical and ultrastructural studies, together with the presence of bone metastases, led to the diagnosis of an ACTH-producing neuroendocrine carcinoma. He was initially submitted to chemotherapy and has been on treatment with octreotide LAR since 1998, having shown a favorable clinical, biochemical and imaging response. We highlight the excellent long-term response to medical therapy with octreotide LAR, without tachyphylaxis, probably due to its antiproliferative effect.

The synchronous primary lung tumors is a rare condition and presented patient is the first reported case of simultaneous two distinct neuroendocrine lung cancer lesions in the same lobe. We present the case of a 55-year-old woman with synchronous two distinct neuroendocrine lung cancer lesions in the right upper lobe. Initially she showed no signs or symptoms related to lung lesions and was admitted to Thoracic Surgery Ward for the investigation of two oval, solitary pulmonary nodules (11 and 19 mm in diameter) detected on a chest X-ray performed three months earlier. The radiological imaging showed a variability of growth of both lesions (smaller tumor has enlarged while the larger one remained unchanged). After the CT-guided lung biopsy, patient underwent right upper lobectomy. Histological examination revealed a small cell carcinoma in one of the tumors and a large cell neuroendocrine carcinoma in the other one. The patient was discharged in good condition and lung inflation in chest X-ray and qualified for adjuvant chemotherapy with a combination of cisplatin and etoposide and the prophylactic cranial irradiation. Very important issues, having impact on outcome of patients with multiple lung tumours is differentiation whether the lesions are metastases or synchronous primary lung tumors and the optimal management of these patients.

Nestin is considered to be a cancer stem cell marker. Nestin expression in neuroendocrine tumours might be useful to predict prognosis and facilitate treatment planning. 88 patients with neuroendocrine lung tumours operated in the Department of Thoracic Surgery from 2007 to 2015 were included into the study. Immunohistochemical staining for nestin was performed. Clinicopathological and survival data were retrospectively analyzed. Nestin expression was detected in 15 (17%) specimens. Multivariate analysis showed that lymph node metastases (p = 0.0001; hazard ratio (HR) = 3.93; confidence interval (CI) 95%: 1.96-7.87), nestin expression (p = 0.034; HR = 2.30; CI 95%: 1.06-4.99) and patient's age (p = 0.024; HR = 1.04; CI 95%: 1.00-1.09) were independent negative prognostic factors. Nestin expression was significantly higher in large cell neuroendocrine carcinoma when compared with carcinoids (p = 0.001). Collected data support the thesis that nestin can be regarded as a biomarker in patients with neuroendocrine lung tumours.
