Laboratory Studies
- None
Imaging Studies
- Ultrasound of the leg can exclude vascular abnormalities such as arteriovenous fistula.
- Plain radiographs can exclude abnormalities of the bone.
- After a subcutaneous injection of dye, lymphangiography of patients with Milroy disease shows lymphatic vessels that cannot be cannulated.
- Lymphoscintigraphy using the subcutaneous injection of technetium-labeled colloid demonstrates an absence of lymphatic vessels.
- Fluorescence microlymphography using a light fluorescence microscope following subepidermal infection of FITC-dextran 150,000 demonstrates a lack of microlymphatics.[12]
- MRI can also be used; however, it is more useful to show lymph trunk anatomy and causes of obstructive secondary lymphedema.
Procedures
- Biopsy of the skin is performed using standard techniques. A 25-gauge needle is used to infiltrate the skin with local anesthesia. The skin is stretched perpendicular to the desired line of the scar. A punch biopsy tool is rotated into the skin to obtain a small circle of tissue, which is sent to pathology for histologic staining. Bleeding is controlled by the application of pressure to the area or by the use of a single suture. Topical antibiotics applied twice daily speed wound healing.
Histologic Findings
Early in the disease, lymphatic vessels are conspicuously absent upon biopsy. Late in the disease, histology shows lymphangiectasia and fibrosis involving the subcutaneous skin.
