Intralesional Endoscopy and Septectomy as a Diagnostic Tool and Treatment Method for Lymphatic Malformations

Sclerotherapy and surgery are both effective treatment methods for lymphatic malformations.1,2 However, recurrence due to incomplete resection is a common problem, often necessitating multiple treatment sessions.2 Intralesional endoscopy has been described as a diagnostic approach and potential therapeutic tool.1,3 We report a case of a 12-year-old male patient who presented with a mainly subcutaneous mixed lymphatic malformation located on the right flank (►Fig. 1). After suffering a direct trauma, the lesion had increased markedly in size and surgical interventionwas indicated due to the associated pain. Intralesional endoscopy was performed that showed a mixed macro-/microcystic lymphatic malformation with hemorrhage (►Fig. 2). Intercystic septa were dissected under endoNew Insights and the Importance for the Pediatric Surgeon
