Leiomiossarcoma de veia cava inferior / Leiomyosarcoma of the inferior vena cava

We present a case of a 56-year-old woman with abdominal pain, normal laboratorial exams, normal carcinoembryonary antigen (CEA) and abdominal tomography exam with tumor formation in hepatic region. A tumor lesion was identified in a surgery in the medial segment of the inferior vena cava. A surgical resection was done, respecting the security limits, and reconstruction of the inferior vein with polytetrafluoroethylene (PTFE) graft was performed. The histological examination showed differentiated leiomyossarcoma of the inferior vena cava. This report points to the necessity of differential diagnoses with leiomyossarcoma in the presence of abdominal mass, supra-mesocolic, and non-specific abdominal symptoms, since its pre-surgical diagnoses occurs in only 5 percent to 10 percent of the cases.

Embora näo freqüentemente, associaçäo entre psoríase vulgar e nefropatia membranosa tem sido relatada, sendo um mecanismo auto-imune comum sugerido como a origem desta associaçäo. Apresetam-se os casos de 2 pacientes portadores de psoríase vulgar que desenvolveram nefropatia membranosa durante o curso da dermatose e que, apesar das terapêuticas utilizadas, evoluiram para insuficiência renal crönica terminal. Estes säo, provavelmente, os primeiros casos descritos desta associçäo no país (au)
