ABSTRACT
De todas las neoplasias malignas de mama los carcinomas ductales son los más frecuentes. Menos del 5% son denaturaleza metaplásica y 0,04%-0,1% presentan diferenciación de células escamosas, subtipo que se considera más agresivo. Debido a los pocos casos en la literatura,no hay consenso sobre su diagnósticoy tratamiento. Presentamos tres casos con ese diagnóstico vistos entre 2014 y 2015 en nuestra institución y que corresponden a mujeres de 57, 49 y 65 años sin factores de riesgo y que presentaron cuadros clínicos similares consistentes con aparición de masa de crecimiento rápido. Dos de las pacientes se habían diagnosticado previamente con carcinoma ductal infiltrante de tipo no especial en biopsias por tru-cut con diagnóstico definitivo en la mastectomía radical que reportó en todos los casos carcinoma metaplásico escamoso confirmado por inmunohistoquímica.
Ductal carcinomas are the most common of all breast malignancies, less than 5% are of metaplastic nature, and 0.04% to 0.1% have squamous cell differentiation. These special subtypes are considered more aggressive. Due to the few cases in the literature, there is no consensus about its diagnosis and treatment. Three cases are presented with this diagnosis, seen in our institution between 2014 and 2015. They were women of 57, 49, and 65 years old with no risk factors, and who presented with similar clinical features, consisting of the appearance of a rapid growing mass. Two of the patients had been previously diagnosed with infiltrating ductal carcinoma of no special type by core needle biopsy, with a definitive diagnosis in radical mastectomy, which reported squamous metaplastic carcinoma confirmed by immunohistochemistry.

El coloboma ocular es una entidad infrecuente provocada por el cierre incompleto de la fisura embrionaria entre la quinta y la séptima semana de gestación. Se presenta el caso de una paciente de 6 años admitida por urgencias por presentar trauma contundente en el ojo derecho, es valorada por oftalmología, que encuentra en la ecografía ocular bilateral, compromiso de ojo derecho con ectasia y herniación secundaria del humor vítreo hacia la pared posterior del globo ocular y desarrollo anormal de la retina, coroides y esclera. Se decide realizar procedimiento quirúrgico que se lleva a cabo sin complicaciones. Patología reporta, cambios de metaplasia del contenido "Uveo-retiniano", formando cartílago, musculo y tejido adiposo, que se dispone de forma desordenada en un estroma fibroso, realizando diagnóstico de Coloboma Uveal.
Ocular coloboma is an uncommon condition caused by an incomplete closure of the embryonic fissure between the fifth and the seventh week of gestation. We reported a case of a 6 year old patient who was evaluated by ophthalmology service at emergency room after blunt trauma in the right eye. Patient was evalutated bilaterally with ocular ultrasound which showed, commitment ectasia right eye and vitreous herniation secondary to posterior wall eyeball and abnormal development of the retina, choroid and sclera. Was decided to perform a surgical procedure is performed without complications. Pathology reports, content metaplastic changes "uveo-retinal" forming cartilage, muscle and adipose tissue, which is arranged in a disorderly manner in a fibrous stroma, making diagnosis of Uveal Coloboma.
