Kaposiform lymphangiomatosis is a rare lymphatic anomaly that occurs in children and is associated with life-threatening complications. The somatic mutation NRAS Q61R (c.182A>G) has been identified in lesional tissue samples of patients with kaposiform lymphangiomatosis, and can be used to differentiate this condition from other complex lymphatic anomalies and to guide treatment. Tissue sampling in this lymphatic anomaly is inherently risky due to its involvement of thoracic and abdominal organs and associated coagulopathy. Analysis of cell-free DNA isolated from blood plasma presents a promising noninvasive diagnostic strategy. Here, we describe the use of this approach using a commercial assay.
