Advances in the Treatment of Congenital Infiltrating Lipomatosis of the Face: The Role of PIK3CA Mutations and Microvascular Reconstruction.

Congenital infiltrating lipomatosis of the face is a rare aggressive-benign disorder characterized by progressive hemifacial overgrowth and complex, often asymmetrical, facial differences. Recently linked with the PIK3CA-Related Overgrowth Spectrum, it arises from mosaic mutations in the PIK3CA gene. Treatment, largely supportive and tailored to individual clinical presentations, requires a multidisciplinary approach. This article reviews the longitudinal care of a young adult patient from 8 years of age, detailing his journey through combined orthognathic and microvascular reconstructive surgery and the outcomes thereof. In addition, it explores the treatment's implications in the context of the PIK3CA mutation, offering insights into potential prognostic and therapeutic considerations.
