  • Title: Intrathoracic glial implants in a child with gliomatosis peritonei.
    Author: Lipskar AM, Rothstein DH, Soffer SZ, Edelman M, Glick RD.
    Journal: J Pediatr Surg; 2009 Sep; 44(9):1817-20. PubMed ID: 19735831.
    Abstract:
    Glial peritoneal implants, commonly referred to as gliomatosis peritonei, are an occasional feature of ovarian teratomas. They are benign nodules of mature glial tissue and usually do not adversely affect outcome. We present the case of a 12-year-old girl who underwent excision of an immature ovarian teratoma, along with biopsies of multiple glial peritoneal implants. She also had a 2-cm right-sided pleural mass, which turned out to be normal glial tissue that was histologically indistinguishable from the peritoneal glial tissue. Pleural gliomatosis has not been described in the literature. The pathophysiology of gliomatosis peritonei was originally thought to be the direct extrusion or lymphatic spread of glial cells from the associated teratoma, although it has been postulated that the glial implants may instead be the result of pluripotent Mullerian stem cells that undergo metaplasia. This report provides evidence to bolster the metaplastic theory.
