ABSTRACT
ABSTRACT Objective: To evaluate the technique of uterine transplantation and the use of drugs used in the process of immunosuppression. Methods: We included 12 sows, and immunosuppression was performed with minimal doses of cyclosporine, and cross-match was done to exclude the possibility of blood incompatibility. Hysterectomy was performed in the donor under general anesthesia, with the removal of the aorta and inferior vena cava in monobloc, and anastomosis of these vessels was made in the recipient. Results: Six experiments were performed, and on the immediate postoperative period, five animals had good reperfusion. However, on the seventh postoperative day, histological analysis showed rejection in five animals. Conclusion: The experimental model of uterine transplantation is feasible, but monitoring doses of immunosuppressants is pivotal to prevent rejection episodes.
RESUMO Objetivo: Avaliar a técnica de transplante uterino e o uso de drogas no processo de imunossupressão. Métodos: Foram incluídas 12 porcas, sendo realizada imunossupressão com doses mínimas de ciclosporina, e prova cruzada para afastar a possibilidade de incompatibilidade sanguínea. Realizou-se, na doadora, histerectomia sob anestesia geral, com a retirada, em monobloco, da aorta e da veia cava inferior, de tal forma que, na receptora, fosse possível realizar a anastomose com estes vasos. Resultados: Foram realizados seis experimentos e, no pós-operatório imediato, houve boa reperfusão em cinco animais. Entretanto, no sétimo dia de pós-operatório, as análises histológicas demonstraram rejeição em cinco deles. Conclusão: O modelo experimental de transplante uterino é factível, mas a monitorização das doses de imunossupressores é importante, a fim de impedir os episódios de rejeição.

Abstract Genital leiomyomas are rare tumors that can often be misdiagnosed as Bartholin cyst. We report a case of a 32-year-old patient who had a cystic nodulation in the left labium majus that was suggestive of Bartholin cyst. A resection surgery was performed, and the definitive histopathology diagnosis was vulvar leiomyoma. The macroscopic features of cystic lesions difficult the differential diagnosis between leiomyoma and Bartholin cyst; therefore, a histopathologic examination is often recommended.
Resumo Os leiomiomas genitais são tumores raros, e frequentemente são diagnosticados como cisto de Bartholin. Relatamos o caso de uma paciente de 32 anos em que ocorreu nodulação cística no grande lábio esquerdo sugestiva de cisto de Bartholin. Uma cirurgia de ressecção foi realizada, e o diagnóstico histopatológico definitivo foi leiomioma vulvar. As características macroscópicas das lesões císticas dificultam o diagnóstico diferencial entre o leiomioma e o cisto de Bartholin, demodo que o exame histopatológico é frequentemente recomendado.
