Discordant Schimmelpenning-Feuerstein-Mims syndrome in monozygotic twins after successful laser coagulation for twin-to-twin transfusion syndrome

Introduction: Monochorionic twins are by definition monozygotic. Schimmelpenning-Feuerstein-Mims syndrome (SFM) is a rare disorder characterized by sebaceous nevi associated with abnormalities of the central nervous system, eyes and skeleton. We report the third case of discordant occurrence of SFM in monochorionic twins.

Ultrasound examination revealed a twin-to-twin transfusion syndrome (Quintero stage 3) defined by polyhydramnios along with abnormal Doppler flow…
