Although very rare, cystic adenoid carcinoma (CAC) should be considered as a differential diagnosis for any lung tumor arising from the bronchial glands. The diagnosis is typically confirmed through histological examination, and treatment is primarily based on surgical intervention. In this report, we present the case of an 82-year-old male with primary CAC of the lung.
Malignant mesothelioma is a rare and aggressive cancer that usually affects subjects with prior asbestos exposure, a major risk factor that has been widely known as carcinogenic, and its use is now controlled if not banned in many areas of the world. Malignant mesothelioma originates from mesothelial surface cells covering the serous cavities, and the pleura is its most common site. Malignant pleural mesothelioma (MPM) typically presents with pleural effusion and chest wall pain with wide pleural thickening at radiological investigation. Although the histological examination along with immunohistochemistry helps yield the diagnosis, clinicians and experts face many challenges in diagnosing malignant mesothelioma not only due to the rarity of the disease but also due to the similarities that the disease share with other malignancies.
Here, we report a case of a 55-year-old male patient with a history of chronic asbestos work exposure for 12 years who initially presented with unexplained pleural effusion and chest wall pain and was lost to follow-up but came back later with a worsening clinical state. This case is specially presented to raise awareness against cases of unexplained pleural effusion and chest pain.
Chylothorax is defined by the presence of chyle in the pleural cavity. The diagnosis is mainly based on the dosage of triglycerides and/or the detection of chylomicrons in the pleural fluid. The most common causes of chylothorax are traumatic, mainly following surgery. Among the non-traumatic causes, we frequently find tumors and in particular lymphomas. The first-line treatment is conservative and consists of pleural drainage associated with a low-fat diet. We report the case of a 78-year-old man with rest dyspnoea, in whom the pleuropulmonary examination found a bilateral fluid effusion syndrome, the exploratory pleural puncture showed the presence of sero-sanguinous fluid, exudative with a triglyceride levels = 626 mg/dl in the left and 455 mg/dl in the right . The diagnosis of small B-cell lymphocytic-type lymphoma was retained following an anatomopathologic study of the adenectomy specimen.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
