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...

Solitary pulmonary nodules are common, often incidental findings on chest CT scans. The investigation of pulmonary nodules is time-consuming and often leads to protracted follow-up with ongoing radiological surveillance, however, clinical calculators that assess the risk of the nodule being malignant exist to help in the stratification of patients. Furthermore recent advances in interventional ...

BACKGROUND Pulmonary glandular papillomas are rare neoplasms, and their very slow or absent growth over time generally facilitates establishing the diagnosis. CASE PRESENTATION In an 84-year-old woman who underwent surgery for sigmoid colon cancer, a growing solitary pulmonary nodule was identified on postoperative follow-up computed tomography. A computer tomography-guided needle biopsy was ...

Pulmonary nodule is one of the important lesions of lung cancer, mainly divided into two categories of solid nodules and ground glass nodules. The improvement of diagnosis of lung cancer has significant clinical significance, which could be realized by machine learning techniques. At present, there have been a lot of researches focusing on solid nodules. But the research on ground glass nodules...

It has long been recognized that tumors of capillary vessels in the lung are extremely rare. While pulmonary capillary hemangiomatosis, which is a rare cause of pulmonary hypertension, is relatively well known, there have been only a few reports of solitary capillary hemangioma (SCH) of the lung. Herein we report two cases of SCH. Both cases were first detected as a solitary nodule of the lung ...

The approach to patients with indeterminate pulmonary nodules is poorly defined. Should every pulmonary nodule be biopsied, is needle biopsy adequate, and other questions are challenges. Video assisted thoracic surgery or thoracoscopy has added a new diagnostic possibility which is evaluated in this paper. Fifty-five patients underwent thoracoscopy for diagnosis of a solitary pulmonary nodule. ...

Asymptomatic solitary pulmonary nodules incidentally revealed by computed tomography has become a serious medical problem. Depending on their diameter, solid, part-solid, or pure ground-glass pulmonary nodules may be observed, diagnosed radiologically/invasively, or resected in accordance with international guidelines. Pure ground-glass nodules, semi-solid lesions, or solid lesions smaller than...

A 38-year-old female was found to have multiple bilateral lung nodules in a routine chest X-ray examination. Thoracoscopy was performed with biopsy of three nodules from the right lower lobe and Congo red staining showed typical amyloid pattern. Initial diagnosis of pulmonary nodular amyloidosis was made. However, one nodule in the right upper lobe enlarged as detected by follow-up CT scan. The...

Background: The role of fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) in the surgical approach solitary pulmonary nodule (SPN) is still debated, as increased metabolic avidity lesion was not a sure sign malignancy. purpose this study to evaluate effectiveness 18F-FDG-PET/CT characterization SPN based on analysis most recent data literature.

We report an extraordinary case of collision tumor consisting of a lung adenocarcinoma and a metastatic adenoid cystic carcinoma in a 56 year-old man. He was diagnosed with a pulmonary nodule 11 years after treatment of an adenoid cystic carcinoma of the right maxillary sinus. A non-small cell carcinoma was observed when a transbronchial biopsy was performed. The other component of the nodule w...
