Medulloepithelioma of the optic disc
Human Pathology, 2011A 6-year-old boy with a history of an amblyopic, occasionally red left eye was found to have a solid white mass overlying the optic disc on dilated ocular fundus examination. Transvitreal endoincisional biopsy of the mass yielded neoplastic tissue consistent with intraocular medulloepithelioma.

Echographic features of medulloepithelioma
American Journal of Ophthalmology, 2000To evaluate the echographic features of medulloepithelioma that may assist in establishing the diagnosis.Retrospective review identified four eyes with medulloepithelioma studied with echography. Clinical records, echographic findings, histopathologic tumor features, and the clinical course were reviewed.The initial preoperative diagnosis of ...

Teratoid Intraocular Medulloepithelioma
American Journal of Ophthalmology, 1978The right eye of a 1-year-old black infant with a painful blind eye was studied histologically. It contained a tumor at an advanced stage of growth. The tumor consisted of moderately large, round, and elongated undifferentiated cells and anaplastic cells with mitotic figures combined with multilayered, poorly differentiated epithelial cells that ...

Sellar and suprasellar medulloepithelioma
Pediatric Radiology, 2001Medulloepithelioma is a rare tumour with a very poor prognosis. The most frequent site in the central nervous system is the cerebral hemispheres. Appearances on MRI are very variable, possibly reflecting the divergent forms of differentiation seen at histological examination.

Fine Structure of Medulloepithelioma
Journal of Neuropathology & Experimental Neurology, 1977A survey of published cases of medulloepitheliomas indicates that this tumor is highly malignant (average course 6 months), occurs in early childhood (average age 4,4 years) and has no sex predilection. Although it may originate in any part of the central nervous system, it is most common in the cerebral hemispheres.

Medulloepithelioma of the Optic Nerve Head
Archives of Ophthalmology, 1997Medulloepithelioma of the optic nerve is a rare developmental tumor. We describe a 2-year-old boy with profound loss of vision associated with a visible tumor of the optic nerve head in his left eye. A clinically diagnosed retinoblastoma necessitated left eye enucleation.

Medulloepithelioma: MRI Appearances
Australasian Radiology, 1988ABSTRACTThe M.R.I. appearances of a rare tumour of childhood are presented. The clinical presentation and imaging appearances of medulloepithelioma are discussed. The importance of both C.T. and M.R.I. in the pre‐operative evaluation of this tumour is outlined.

Pediatric Neurosurgery, 1979
A cerebral medulloepithelioma, a rare embryonal multipotential central neuroepithelial neoplasm of childhood, is described, bringing to 16 the total number of cases reported in the literature. It is the first example recorded to date which displayed the entire range of differentiation from embryonal to mature cells, of both glial and neuronal lineage ...

Neglected malignant medulloepithelioma of the eye
Orbit, 1999Intraocular medulloepithelioma is a rare tumor usually arising from the ciliary body and presenting in childhood. We recently managed a case of an advanced medulloepithelioma in a 45-year-old man that went untreated for several years. The patient had an exenteration after the tumor destroyed the eye and extended into the central nervous system.
