Cat scratch disease, a mild flu-like infection, with swollen lymph nodes (lymphadenitis) and mild fever of short duration, due to cat scratches, especially from kittens. There is usually a little bump (a papule) which may be pus-filled (a pustule) at the site of the scratch. The infection is self-limited and usually goes away by itself in a few weeks. It can also be treated with antibiotics, but it can cause a severe inflammation called bacillary angiomatosis in patients with weakened immune systems. A cat carrying the microbe does not show symptoms and it is not necessary to get rid of it. If someone in the household is at high risk, a test to detect the infection can be done and the cat can be treated. The disease is caused by a bacterium called Rochalimaea henselae, eventually reclassified as Bartonella henselae, named for Diane Hensel, a microbiologist. The disease has also been called benign lymphoreticulosis.
Abnormally enlarged lymph nodes. Commonly called swollen glands.

An X-ray of the lymphatic system for which a dye is injected to outline the lymphatic vessels and organs.
LAM is generally progressive, leading to increasingly impaired lung function. The rate of development can vary considerably among patients. As the disease advances, there is more extensive growth of muscle cells throughout the lung and repeated leakage of fluid into the chest cavity (pleural effusions). As an increasing number of cysts are formed, the lung […]
An abnormal structure that consists of a collection of blood vessels and lymph vessels that are overgrown and clumped together. Depending on its nature, a lymphangioma may grow slowly or quickly. Lymphangiomas can cause problems because of their location. For example, a lymphangioma around the larynx might cause a breathing problem.
