Subtypes include Squamous Cell Carcinoma, Adenocarcinoma, and Large Cell Carcinoma. Small Cell Lung Cancer Also known as Oat Cell Cancer, this makes up 10-15% of lung cancer cases and tends to spread quickly. Lung Carcinoid Tumor Responsible for under 5% of lung cancer cases, these are also ...
Bronchial carcinoidsaccount for up to 5% of lung cancers. Physicians sometimes refer to these tumors as lung neuroendocrine tumors. They are generally small (3 cm-4 cm or less) when diagnosed and occur most commonly in people under 40 years of age. Unrelated to cigarette smoking, carcinoid tu...

People with SPNs usually do not experience symptoms. SPNs are usually noticed by chance on a chest X-ray that has been taken for another reason (referred to as an incidental finding). SPNs are a common abnormality seen on chest X-rays that often needs further evaluation. Approximately 150,...
Carcinoid tumors are relative rare neuroendocrine tumors of the lung. Bronchial obstruction's symptoms as cough, hemoptysis and pneumonia may be present when they are centrally located and lung-sparing surgery is usually preferred. We describe the case of an adult patient with a central right upper...
(ACCP) guidelines, the initial evaluation should be complete within six weeks in patients with tolerable symptoms and no complications. Only 26% and 8% of cancers are diagnosed at stages I and II, respectively, whereas 28% and 38% are diagnosed at stages III and IV respectively. Therefore, ...
Diagnosis may be complicated by the paucity of signs and symptoms or by an atypical presentation. Prompt institution of empiric antimicrobial therapy is usually warranted, particularly in life-threatening infections. This review will focus on the epidemiology, diagnosis, and management of particular ...
In addition to bronchogeniccarcinoma, the differential diagnosis also includes other tumors such ascarcinoidandmetastatic disease. The most common benign cause of SPN in most series isgranuloma, often resulting from prior infection from endemic fungi ormycobacterium. Other etiologies includechronic inflammati...
38%, squamous cell carcinoma 20%, small cell (neuroendocrine) carcinoma 13%, and large cell carcinoma 5%. The remainder are composed of variant carcinomas, sarcomatoid (spindle cell) carcinomas, salivary-type carcinomas, neuroendocrine-carcinoid carcinomas, and others....
Neuroendocrine tumors of the lung.SCLC is a type of neuroendocrine cancer and there are three other less common neuroendocrine tumor types: typical carcinoid, atypical carcinoid, and large cell neuroendocrine carcinoma. The first two are less common in smokers and generally less aggressive, while the...
