Long-term outcomes of lymphatic malformations in children: An 11-year experience from a tertiary referral center

•LMs are congenital conditions, for which various treatment options and combinations are available.•Most studies of LMs have focused on LMs in a single location.•We evaluated an entire LM cohort of pediatric patients treated at a single tertiary unit over 11 years.•Careful multidisciplinary assessment is essential for planning management of symptomatic cases to achieve optimal outcomes. Lymphatic malformations (LMs) are benign, congenital lesions that display considerable heterogeneity in terms of size, location and characteristics. This study aims to describe the long-term outcomes of current management strategies for patients with simple (cystic) LMs. The case records of all patients (age ≤16 years) with simple (cystic) LMs at our tertiary institution between 2008 and 2019 were assessed for clinical features, imaging and details of management, including complications. Of a total of 164 patients (60% male), 66% were diagnosed aged
