RESUMO
History A 70-year-old man was referred to our institution with chronic obstructive urinary symptoms and constipation for 2 years before admission. His medical history was unremarkable. Outside laboratory tests revealed an elevated serum prostate-specific antigen level (21.7 ng/mL [normal range, 0.00-4.00 ng/mL]), and urinalysis results were negative. He was admitted for evaluation of possible prostate cancer. The patient reported no specific symptoms of infection and denied fever, dysuria, hematuria, and abdominal pain. He had no family history of prostate cancer. On physical examination, he was afebrile, and the digital rectal examination was not painful. These findings were evidence of an enlarged prostate and a hard multilobulated mass, which was palpable bilaterally. The urologic team performed MRI of the prostate.

RESUMO
Eosinophilic solid and cystic renal cell carcinoma (ESC RCC) is a recently described entity with distinct clinical, pathologic, and molecular features. However, the radiological aspects of ESC RCC have not been characterized. In this report, we describe the imaging findings of 2 ESC RCCs. We found 2 distinct imaging patterns that varied depending on histopathologic features (solid or cystic predominance). In conclusion, it is important to know the imaging characteristics and pathologic correlation of this novel neoplasm to increase its recognition and to improve the decision-making process.

Pouco mais de dois anos após a descoberta dos raios-X por Roentgen, o médico José Carlos Ferreira Pires já produzia, em Formiga, as primeiras radiografias com finalidade diagnostica da América do Sul. O aparelho era rudimentar, com tubos tipo Crookes e bobinas de Rhumkorff. Como não havia eletricidade no município, foi necessário um enorme esforço para colocar o aparelho em funcionamento. Na época, Dr. Pires também publicou diversos trabalhos na área de Radiologia em congressos médicos e revistas científicas.
Amost two years after the discovery of X-rays by Roentgen, doctor José Carlos Ferreira Pires produced in Formiga the first diagnotic X-rays in South America. The machine was very simple, with rudimentary tubes (Crookes) and Rhumkorff coil. No electricity was available in his city, which demand an enormous effort to produce the radiographs. At that time, Dr. Pires also published many articles about Radiology in scientific journals and meetings.
