IntroductionTesticular cancer is the most common malignant neoplasm in men between the ages of 15 and 35, although it accounts for only 1% of male malignancies [1]. 95% originated from germ cells, which are the main cell type of the testis, and more than half of the germinal tumors contain a mixture of multiple histological types, forming mixed entities [2,3].Germ Cell Tumors (GCT) occur at all ages, and there are clearly identified risk factors, including: congenital genital malformations such as: undescended testis, family history of testicular tumors in first-degree relatives (father and siblings, 6 and 10 times more risk respectively), presence of contralateral tumor, infertility and exposure to diethylstilbestrol [4].The yolk sac tumor (YST), also known as endodermal sinus tumor, is the most common GCT in infants and children, accounting for 80% of germ cell tumors in this age group [5]. It is observed only in 2.4% of adult patients in their pure form since up to 42% of mixed GCTs have some component of the yolk sac [6].Due to the unusual presentation of the YST beyond de pediatric age (there are less than ten cases reported in the literature) there is no consensus in therapy after radical orchiectomy.We present the case of a 20-year-old male with a pure YST in the right testicle, metastatic to liver, retroperitoneum, and lung; with an evolution of approximately three months from diagnosis to death. Case ReportA previously healthy 20-year-old man, consulted to the emergency department for two days of emesis and abdominal pain associated with jaundice.On physical exam, the patient was stable, conscious and icteric. He had a distended abdomen, painful on palpation, but without signs of peritoneal irritation.Laboratory findings showed pancreatic amylase and hepatic transaminases were high. The CT scan of the abdomen showed a hypodense image in the pancreas head and duodenum, as well as a hepatic and retroperitoneal mass with thickening of the mesentery and pleural effusion.Based on the previous history, the initial diagnosis was an abdominal sepsis secondary to severe acute necrotizing obstructive pancreatitis by AbstractIntroduction: We present the case of a 20-year-old male with a pure yolk sac tumor in the right testicle and metastatic disease to liver, retroperitoneum, and lung; with an evolution of approximately three months from diagnosis to death.

The objective of this study was to establish the rates of sexual satisfaction in both the patient and his partner, after penile prosthesis implantation (PPI). Materials and Methods: This is an observational cross-sectional study, in which 32 individuals who underwent PPI between the years 2009 and 2016 in two university hospitals, in Bogotá, were selected. Demographic data and medical history were collected from the medical records. Subsequently, the erectile dysfunction (ED) Inventory of Treatment Satisfaction survey was applied. Finally, the data were processed in Excel, and a descriptive analysis was made for the continuous variables, with measures of central tendency (medium and medium). For the categorical variables, frequency measures were used and interpreted with percentages. Results: Thirty-two patients were interviewed. 78% had an inflatable prosthesis and 22% malleable. The most frequent complication was infection in 4 patients (16%), which led to extrusion and removal of the prosthesis in 3 cases. 55% report that the implant increased the number of sexual intercourse per week. The overall satisfaction was 75% in men and 66.7% in their partners. For 70% the prosthesis met their expectations, 80% were satisfied with the speed and 90% with the duration of the erection, and 93% of couples considered that men wish to continue using this method. Conclusion: We found high rates of sexual satisfaction in patients and their partners that allow us to deduce that the penile prosthesis is a feasible option in patients with ED refractory to the first-and second-line treatment.
