Introduction: Pentalogy of Cantrell is a rare congenital disorder characterized by midline birth anomalies. Its embryological origins are related to anomalies of the abdominal wall that prevent the closure of the thorax. Its etiology is not yet clear, but it has been associated with a failure of migration of the lateral plate mesoderm to the midline. Case description: A stillbirth at 25.2 weeks of gestation diagnosed with pentalogy of Cantrell. The mother was a 14-year-old teenager with no relevant history of disease. An obstetric ultrasound was performed at 19 weeks of gestation and revealed findings suggestive of pentalogy of Cantrell. The mother was informed of the potential risks and future complications for the fetus, yet she chose to continue with the pregnancy. At 25.2 weeks of gestation, the mother went to the emergency department due to pain in the hypogastrium accompanied by moderate vaginal bleeding and absence of fetal activity. Once fetal death was confirmed by ultrasound, labor was induced, resulting in stillbirth with anencephaly, thoracic hypoplasia, gastroschisis, and eventration of the liver. Conclusions: Adequate antenatal care, including strict ultrasound follow-up, is essential to detect future complications in the fetus; to provide advice on possible malformations incompatible with life, such as pentalogy of Cantrell; and to determine the best therapeutic approach.

Las metástasis tumor a tumor (MTT) corresponden a un evento poco frecuente en el cual se presenta metástasis de un tumor primario a otro tumor primario, bien sea benigno o maligno. El carcinoma de pulmón es un receptor poco habitual, pero uno de los donantes más frecuentes. En el presente articulo presentamos tres casos de MTT como órgano receptor el pulmón: el primero, de una mujer con antecedente de carcinoma papilar de tiroides y carcinoma ductal in situ de la mama, con presencia de MTT y carcinoma papilar de tiroides a un adenocarcinoma primario pulmonar. El segundo caso, es una mujer con MTT de carcinoma ductal de mama a un adenocarcinoma primario pulmonar. Y el tercero, de un MTT de un carcinoma ductal de mama a un hamartoma pulmonar. En los tres casos, fue fundamental la correlación clínico-patológica y los estudios complementarios de inmunohistoquímica.
