Plexiform neurofibroma during and after pregnancy

Abstract

Neurofibromatosis is a genetic disease that affects multiple organ systems, and has a wide range of clinical features. Neurofibromatosis in pregnancy is encountered with a frequency of 1:2434 to 1:18,500 deliveries. Plexiform neurofibromas are rare subcutaneous nodules or amorphous overgrowth of subcutaneous tissues, which may affect the underlying bone, and produce deformities. We present a patient with a giant plexiform neurofibroma of the thigh which got larger in pregnancy, and shrunk a bit in the postpartum period.
