Neurocytoma Arising in an Adrenal Gland Mature Teratoma.

Mature teratoma of adrenal gland is a rare entity. Neurocytoma is a low grade neuronal tumor even rarely seen among central nervous system tumors. Nervous system tumors arising in teratomas are frequently originated from glial or primitive neuroectodermal cells. Here we report a neurocytoma arising in mature cystic teratoma in the right adrenal gland of an 8 years old boy. Histological examination revealed a tumor composed of solid sheets in fibrillar basis with small uniform cells in the neuroglial tissue in teratoma. This is only the second case demonstrating a neurocytoma arising in a mature cystic teratoma in the literature. [ABSTRACT FROM AUTHOR]
