Lymphangioleiomyomatosis

Common Name(s)

Lymphangioleiomyomatosis, Lymphangioleiomyomatosis (LAM)

"Lymphangioleiomyomatosis (lim-FAN-je-o-LI-o-MI-o-ma-TO-sis), or LAM, is a rare lung disease that mostly affects women in their mid-forties. In LAM, an unusual type of cell begins to grow out of control throughout the body, including in the lungs, lymph nodes and vessels, and kidneys. Over time, these LAM cells form cysts and clusters of cells, which grow throughout the lungs and slowly block the airways. They also destroy the normal lung tissue and replace it with cysts. As a result, air cannot move freely in and out of the lungs, and the lungs cannot supply enough oxygen to the body’s other organs.

More than 1 out of every 3 people with LAM also develops growths called angiomyolipomas, or AMLs, in their kidneys. People with LAM also may develop growths in other organs, including the liver and brain, and large tumors on their lymph nodes.
There are two forms of LAM: sporadic LAM, which occurs for unknown reasons and LAM that occurs in people with a rare inherited disease called tuberous sclerosis complex. This is often a milder form.
