A few words of thanks would be greatly appreciated.

Carcinomatous lymphangitis - Definition


Carcinomatous lymphangitis is the invasion of lymphatic vessels in the lungs by cancer cells. The cells may be from a tumor in the lungs or the metastasis from a cancer elsewhere, like the breasts, stomach, or thyroid. The symptoms of carcinomatous lymphangitis are a persistent dry cough, a significant shortness of breath, an impaired general condition with loss of appetite, weight loss, and clinical signs of cancer. A chest X-ray or a CT scan enhances diagnostic suspicion by showing small nodules, and an analysis of the bronchoalveolar fluid taken during an endoscopy is often necessary to confirm the diagnosis. Care rests on the research and treatment of primary cancer.
