Background Medulloepithelioma is a rare primitive neuroectodermal tumor of the central nervous system, usually developing in childhood. Due to its rarity, the optimal management is still unknown. The prognosis is poor, especially when resection is incomplete. Adjuvant radiochemotherapy is often indicated. Case presentation We report a rare case of infratentorial medulloepithelioma in a 3 year...

Medulloepithelioma is a rare embryonal tumor of the central nervous system (CNS). Its distinct appearance is characterized by papillary and tubular arrangements of malignant singleto multi-layered columnar epithelium surrounded by an outer basement membrane. For years, this tumor has been viewed as an embryonal tumor that recapitulates the earliest stage of CNS development, namely the neural tu...

In this review, clinical findings, diagnosis, and treatments of pediatric mass lesions the fundus were summarized which are seen less often. Idiopathic choroidal granuloma, medulloepithelioma, juvenile xanthogranuloma, fibrous histiocytoma, intraocular teratoma, ophthalmic findings Klippel–Trenaunay–Weber syndrome summarized. These should be kept in mind for differential diagnosis during ocular...

A case of embryonal medulloepithelioma (diktyoma) presenting with perforated infected eye in a 13-year-old Black African girl is described. The tumour mass occupied most of the deformed eye, and invasion of the sclera anteriorly was seen. There was no evidence of orbital or distant tumour involvement. It is suggested that with increasing age these tumours are more likely to show frankly maligna...

Malignant teratoid medulloepithelioma is an extremely rare tumor occurring in children younger than 5 years of age, arising from ciliary body epithelium or iris but few arise from optic nerve and retina. This report concerns a 5 years old boy who presented with pain, redness and protrusion of right eye. Histopathologically, the tumor was composed of epithelial and sarcomatoid component. The pse...
