Primary tumors of the seminal vesicle are extremely rare. Among them, there is a spectrum of tumors derived from both epithelium and stroma and so classified as epithelial-stromal tumors. Herein, we report a case of a cystadenoma in a 49-year-old asymptomatic man, detected in a routine ultrasonography for liver disease follow-up. The digital rectal examination detected a large mass anterior to rectum and posterior to bladder. Computed tomography scan and magnetic resonance imaging showed a normal prostate and a 9.0 cm cystic tumor, replacing the left seminal vesicle. The gross appearance and microscopic aspect was compatible with cystadenoma of seminal vesicle. Patient's postoperative recovery was uneventful. He is currently alive, 3 years after the diagnosis, with no signs of recurrence.

O transplante de pâncreas representa, no momento, a única terapêutica capaz de determinar estado normoglicêmico constante em pacientes com diabetes mellitus do tipo 1 (DM1), sendo indicado particularmente nas formas graves da doença, geralmente traduzidas pelas complicações secundárias como a retinopatia, neuropatia e nefropatia. Sua indicação mais consagrada é em associação ao transplante renal para portadores de DM1 com insuficiência renal, correspondendo a cerca de 85% dos transplantes de pâncreas no mundo. O transplante de pâncreas após rim constitui outra indicação aceita, uma vez que o paciente submetido previamente ao transplante renal já se encontra sob o uso da imunossupressão. O transplante de pâncreas isolado permanece tema controverso, mas pode ser empregado em pacientes com DM instável ou com complicações secundárias da doença e função renal preservada. No presente artigo, relata-se o primeiro caso de transplante de pâncreas isolado empregando-se órgão total com drenagem vesical realizado no Brasil para o tratamento do DM instável.

Pancreas transplantation is currently the only treatment capable of establishing a constant normoglycemic state in type 1 diabetic patients (DM1). It has been particularly indicated in the most severe forms of the disease, which usually goes along with secondary complications such as retinopathy, neuropathy and nephropathy. Pancreas transplantation has been mostly used in association to kidney transplant in end-stage renal failure DM1 patients and corresponds to 85% of all pancreas transplantation. Other indication is the pancreas after kidney, once the patient previously submitted to kidney transplant is already under immunossupression. Pancreas transplant alone remains a controversial issue, however it may be indicated in brittle DM or in those with other secondary complications and stable kidney function. This paper reports the first case of pancreas transplant alone (whole organ with bladder drainage) performed in Brazil for treatment of brittle DM.
