Periorbital nodular fasciitis arising during pregnancy

open access: yesIndian Journal of Ophthalmology, 2014
Nodular fasciitis (NF) is a benign proliferation of fibroblasts and myofibroblasts that rarely occurs in the periorbital region. We report what we believe to be the first case of periorbital NF associated with pregnancy. A case of intravascular fasciitis,
