[Optic nerve pilocytic astrocytoma with retinal involvement]. / Astrocitoma pilocítico de nervio óptico con afectación de retina.

INTRODUCTION: This is an atypical case of a pilocytic astrocytoma that involved the optic nerve (ON) and the retina. CLINICAL CASE: The patient was a 30-year-old male, who had attended ONCE since his early childhood because of the suspicion of an intraocular tumor. The ophthalmology exploration showed an ON and retinal coloboma in the right eye and microphthalmy, shutting of the pupil, retinal detachment and proof of an intraocular tumor in the left eye. The MR revealed an ON tumor that involved the retina. The histopathological study after enucleation was pilocytic astrocytoma. DISCUSSION: Long standing congenital pathology in a blind patient does not exclude the possibility of the patient suffering from other pathology as well.

Astrocitoma pilocítico de nervio óptico con afectación de retina / Optic nerve pilocytic astrocytoma with retinal involvement

Introducción: Se presenta un caso atípico de astrocitoma pilocítico de nervio óptico (NO) y retina.Caso clínico: Varón de 30 años afiliado a la ONCE desde niño, con sospecha de tumoración intraocular. En la exploración oftalmológica: coloboma de NO y retina en ojo derecho y microftalmos, seclusión pupilar, desprendimiento de retina y evidencia de una masa retiniana en ojo izquierdo. La RNM mostró una tumoración de NO y retina. El estudio anatomopatológico tras la enucleación diagnosticó astrocitoma pilocítico de NO y de retina.Discusión: La existencia de una patología congénita en un paciente con ceguera legal no excluye el que pueda presentar otras patologías

[Maxillary ameloblastoma: report of two cases]. / Ameloblastomas maxilares: a propósito de dos casos clínicos.

The ameloblastomas are benign odontogenic tumors locally aggressive that between 15-20% are located in the upper maxillary. The maxillary ameloblastomas have worse forecast than their mandibular homologous upon presenting greater index of postsurgery relapses and a greater percentage of malignancy. Their proximity to nasal cavity, orbit and skull base suppose a risk added by the probability of extension to these structures.

Ameloblastomas maxilares: a propósito de dos casos clínicos / Maxillary amelobastoma: report of two cases

Los ameloblastomas son tumores odontogénicos benignos localmente agresivos que entre un 15-20 por ciento se localizan en el maxilar superior. Éstos tienen peor pronóstico que sus homólogos mandibulares al presentar mayor índice de recidivas postquirúrgicas y un mayor porcentaje de malignización. Su proximidad a fosas nasales, órbita y base de cráneo les hace presentar un riesgo añadido por la probabilidad de extensión a estas estructuras (AU)
