Cutaneous lymphatic malformation with secondary fat hypertrophy

Lymphatic malformations are a type of vascular anomaly. They are uncommon and can present in various ways. Associated hypertrophy of the soft tissue and bone have been described in association with deep lymphatic connections, but late-onset localised fat hypertrophy in the absence of deep connections has not been previously described. We present a case of cutaneous lymphatic malformation of the thigh and buttock with secondary fat hypertrophy. The lesion had been present since childhood but enlarged rapidly during adolescence. MRI excluded deep connections and lipoma. Liposuction was used to debulk the area with a satisfactory result.
