Fetal glial allograft in the endometrium: case report of a recurrent pseudo-tumor

A 32 yr old woman presented with intermittent intermenstrual bleeding, 7 mths after a first trimester termination of pregnancy. Diagnostic curettages at that time and 5 mths subsequently, both produced voluminous curettings, composed of mature glial tissue. Symptoms did not abate and, at hysterectomy, a discrete nodule of endometrial gliomatosis 18 mm in diameter was found, partly sequestered in a mural defect associated with an old anterior lower segment cesarian section scar. The glial tissue was demonstrated to retain histological viability over an 8 mths period since the first diagnostic curettage and 15 mths since the presumed pregnancy of origin.
