Living with Lymphatic malformation 6
A rare inherited condition with widespread lymphedema (swelling from lymph fluid) and sometimes fluid around organs.
Understanding Lymphatic malformation 6
It often involves other body systems, such as lymph vessel problems in the intestines and lungs and fluid around the lungs and heart. Fluid buildup in a baby before birth (non-immune hydrops fetalis) is common and may fully resolve after birth. Some people have severe, recurring facial skin infections. Intelligence is normal, and seizures are absent.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Widespread lymphedema
- Skin infection (cellulitis)
- Eye folds (epicanthus)
- Enlarged spleen
- Fluid around the lungs or heart
- Small lower jaw
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
