Malignant pleural effusion is a condition in which cancer causes an abnormal amount of fluid to collect between the thin layers of tissue lining the outside of the lung and the wall of the chest cavity. [1] Lung cancer and breast cancer account for about 50-65% of malignant pleural effusions.
On radiological studies, thoracic splenic lesions are visualized using CT scans. Visualized lesions can be described as solitary or multiple nodules. The locations of the lesions are mostly in the lower left pleural space and/or splenic bed. Confirmation can be done using scintigraphy with 99mTc tagged heat-damaged red blood cells. [6]
There are two main types of lung cancer, categorized by the size and appearance of the malignant cells seen by a histopathologist under a microscope: small cell lung cancer (SCLC; 15% of cases) and non-small-cell lung cancer (NSCLC; 85% of cases). [18] SCLC tumors are often found near the center of the lungs, in the major airways. [19]
This particular variant of lung cancer is usually asymptomatic and is found after chest x-rays are taken for other reasons. [7] Hemoptysis is seen occasionally [7] and, in some cases, distal obstruction of bronchi by blood clots or mucus plugs produces cough and/or infection. [1] Lesions often enlarge and progress slowly, over many years. [8]
Nearly 40% of lung cancers are adenocarcinomas, which usually originates in peripheral lung tissue. [10] Most cases of adenocarcinoma are associated with smoking; however, among people who have smoked fewer than 100 cigarettes in their lifetimes ("never-smokers"), [11] adenocarcinoma is the most common form of lung cancer.

The incidence of bronchiolo-alveolar carcinoma has been reported to vary from 4–24% of all lung cancer patients. [23] An analysis of Surveillance epidemiology and End results registry ( SEER) by Read et al. revealed that although the incidence of BAC has increased over the past two decade it still constitutes less than 4% of NSCLC in every ...
A neoplasm can be benign, potentially malignant, or malignant . [9] Benign tumors include uterine fibroids, osteophytes, and melanocytic nevi (skin moles). They are circumscribed and localized and do not transform into cancer. [8] Potentially-malignant neoplasms include carcinoma in situ. They are localised, and do not invade and destroy but in ...
