RESUMO
Cystic partially differentiated nephroblastoma is a rare renal tumor of childhood. It is part of a spectrum of multicystic renal tumors that also includes cystic nephroma and cystic Wilms' tumor. We present a case of cystic partially differentiated nephroblastoma, highlighting the clinical and imaging diagnostic challenge. Although the histological diagnostic criteria for all these 3 entities are well established, they are clinically and radiologically indistinguishable. Cystic partially differentiated nephroblastoma is often observed in male children under 2 years old. Typical clinical presentations include abdominal masses, abdominal pain and/or hematuria. Patients should be treated according to tumor histology and stage.
RESUMO
A gravidez heterotópica é uma entidade rara, caracterizada por uma gravidez tópica associada a uma gravidez ectópica, sobretudo quando ocorre de forma espontânea. Os fatores de risco são semelhantes aos vistos em ectópicas, sendo a maior incidência nas mulheres que se submetem a técnicas de reprodução assistida. O diagnostico é feito com ß-HCG positivo e exame ultrassonográfico, geralmente após quadro de abdome agudo hemorrágico decorrente do rompimento da prenhez ectópica, com o tratamento divergindo em relação ao quadro e da idade gestacional da paciente.

The heterotopic pregnancy is a rare disease characterized by a topical pregnancy associated with an ectopic pregnancy, especially when it occurs spontaneously. Risk factors are similar to those seen in ectopic pregnancy, with the highest incidence in women undergoing assisted reproduction techniques . Diagnosis is made with a positive ß -HCG and ultrasound examination, usually after hemorrhagic acute abdomen due to the rupture of the ectopic pregnancy, with treatment differing in relation to the frame and the gestational age of the patient.
