sheep (ovine) pulmonary adenocarcinoma (spa), also known as ovine pulmonary adneomatosis (opa),jaagsiekte and ovine pulmonary carcinoma (opc) is a contagious lung tumor in sheep and, more rarely, ingoats. this study was carried out in khuzestan, in the southwest of iran for a period of six months. a totalnumber of 3985 native breed goats were clinically inspected and postmortem examination was ...

This report describes the case of a 57-year-old man with an anterior mediastinal tumor. Four years previously, he underwent laparoscopic anterior resection for sigmoid colon cancer. Thirty months after that procedure, bilateral pulmonary metastasectomy was performed. Twelve months later, follow-up computed tomography revealed a 1-cm pulmonary nodule on the upper lobe of the right lung and a sol...

We present two cases of occult gastric carcinoma associated to a large pulmonary tumors thrombosis microangiopathy (PTTM). The first case is a 28 years-old man. He was dead due to a respiratory failure. Autopsy showed a whitish indurated mass invading the stomach wall. Histological findings showed a primary "signet ring" gastric adenocarcinoma with pulmonary carcinomatosis and multiple PTTM and...

A 62-year-old woman was found to have multiple bilateral pulmonary nodules showing different (18)F-fluorodeoxyglucose (FDG) uptakes on positron-emission tomography/computed tomography (PET/CT). Only the largest nodule in the left lower lobe showed an increased (18)F-FDG uptake on PET/CT. Three nodules were surgically resected from different lobes of the left lung. Two lobes were benign and show...

We herein report the first case of pulmonary metastasis with lepidic growth that originated from cholangiocarcinoma. A 77-year-old man was admitted to our hospital due to exertional dyspnea and liver dysfunction. Computed tomography showed widespread infiltration and a ground-glass opacity in the lung and dilation of the intrahepatic bile duct. The pulmonary lesion progressed rapidly, and the p...

Pulmonary sclerosing hemangiomas (PSH) of the lung are uncommon tumors and may present cytological atypia with unusual manifestations. The development of PSH combined with other different tumors in lung is extremely rare. We report a case of coexistence of PSH and primary adenocarcinoma in a young female occurring in the same pulmonary nodular mass of right lower lobe. The solitary mass of lung...

We report a rare case of classic pulmonary blastema (CPB) without recurrence for 3 years after the operation. A 70-year-old man presented with cough and sputum for a month. Chest computed tomography (CT) showed a 5cm-sized mass in the right middle lobe. Bronchoscopic examination was performed, and the mass was suspected as adenocarcinoma of the lung. Right middle lobectomy and lymph node dissec...

OBJECTIVES Pulmonary ground-glass nodules (GGNs) are occasionally diagnosed as invasive adenocarcinomas. This study aimed to evaluate the clinicopathological features of patients with pulmonary GGNs to identify factors predictive of pathological invasion. METHODS We retrospectively evaluated 101 pulmonary GGNs resected between July 2006 and November 2013 and pathologically classified them as ...

INTRODUCTION Obstructive jaundice caused by metastases to the distal common bile duct or the ampulla of Vater is often observed in patients with various advanced cancers; however, metastasis of lung cancer to the ampulla of Vater with subsequent development of jaundice is rare. CASE PRESENTATION The patient was a 41-year-old Chinese female who presented with apparent jaundice and itching. An ...

Pulmonary enteric adenocarcinoma (PEAC), a extremely rare variant of primary invasive adenocarcinoma of the lung, was recognized by the international multidisciplinary classification of lung adenocarcinoma which was proposed by the International Association for the Study of Lung Cancer (IASLC), the American Thoracic Society (ATS), and the European Respiratory Society (ERS) published in early 20...
