Lobular panniculitis of the thigh as the only cutaneous manifestation of reactivation of Chagas disease in a renal transplant patient: a case report

Abstract Reactivation of chronic Trypanosoma cruzi infection in solid organ transplant recipients (SOTRs) has been reported. The patient presented with a 2-week history of two painful erythematous, infiltrated plaques with central ulceration and necrotic crust on the left thigh. She had a history of chronic indeterminate Chagas disease (CD) and had received a kidney transplant before 2 months. Skin biopsies revealed lobular panniculitis with intracellular amastigote forms of T. cruzi. The patient was diagnosed with CD reactivation. Treatment with benznidazole significantly improved her condition. CD reactivation should be suspected in SOTRs living in endemic areas with clinical polymorphism of skin lesions.

Treatment of critical lower limb ischemia using a hybrid technique / Tratamento de isquemia crítica de membro inferior com técnica híbrida

Critical ischemia of a lower limb is a condition that threatens its viability and must be treated promptly to avoid major amputation. Revascularization is the most effective treatment method and is performed using surgical or endovascular techniques. For patients with thoracoabdominal aortic aneurysms, combining these two approaches into a "hybrid technique" makes it possible to treat patients who could not be adequately treated by either technique in isolation. We report on a case of lower limb critical ischemia treated using a combination of surgery and endovascular techniques, in an application of the hybrid technique in a different arterial bed...

A isquemia crítica de membro inferior é uma condição que constitui uma ameaça à viabilidade do membro e deve ser prontamente tratada para evitar uma amputação maior. A revascularização é o tratamento mais eficaz, podendo ser por técnica cirúrgica ou endovascular. Nos pacientes com aneurisma toracoabdominal da aorta, a combinação das duas técnicas, denominada técnica híbrida, permite ampliar a possibilidade de tratamento de pacientes que não seriam adequadamente tratados por nenhuma das duas técnicas isoladamente. Descrevemos o tratamento de uma isquemia crítica de membro inferior utilizando a combinação de cirurgia convencional e tratamento endovascular, também se constituindo, assim, em uma técnica híbrida, mas em outro território arterial...
