Living with Microcystic lymphatic malformation

A non-cancerous lump made of small fluid-filled cysts in the lymph channels, often in the head and neck.

Understanding Microcystic lymphatic malformation

Microcystic lymphatic malformation is a rare, non-cancerous growth made of widened lymph channels and small cysts.

The cysts are smaller than 1 centimeter across. They usually show up at birth or in the first years of life and most often occur in the head and neck, but they can occur anywhere. Symptoms depend on where the growth is and how large it is. Infection, injury, or bleeding inside the cysts can make it grow. GARD says it does not turn into cancer.
