RESUMO
INTRODUCTION: Retinopathy of prematurity (ROP) is the first cause of childhood blindness in Argentina and is reaching epidemic proportions. To gain greater insight into the issues involved in this epidemic, we analyzed the characteristics of the infants referred for treatment of very severe ROP to the Dr. Juan P.

Very severe ROP was defined as threshold disease or worse in both eyes, plus disease in zones 1 or 2, or Rush disease. Unusual patients were defined as those with very severe ROP with a gestational age (GA) of > 31 weeks or birth weight (BW) > 1500 g. Patients were divided into two groups according to the distance between the referring center and our hospital: group A consisted of those from nearby areas (

El analisis de los ganglios debe considerar el numero total de comprometidos en relacion al numero total de estudiados, el tamano macro o microscopico de la metastasis la localizacion y la existencia de invasion mas alta de la capsula.El estudio del resto de la mama y la presencia de otros focos tumorales o la patologia benigna asociada completan el examen.Se describe la clasificacion histopatologica de los canceres de mama y una relacion entre el tipo histologico y el pronostico
