Urethral duplication is a rare congenital abnormality with varied clinical manifestations; to this day, <300 cases were reported in the literature. It is affecting mainly males and is nearly always diagnosed in childhood or adolescence. It may be complete or incomplete, and the most widely accepted classification of the different types of urethral duplication was developed by Effman et al. Herein, we present a rare case of urethral duplication revealed by scrotal fistula in an adult man. A duplication is an unusual form of Y-type duplication: it is an incomplete urethral duplication urethra opening on the scrotum without communication with the urethra or bladder.

Background Neuroendocrine carcinomas of the urinary bladder are rare tumors, estimated at less than 1% of urinary bladder malignancies. They are mainly represented by small cell neuroendocrine carcinoma, while large cell neuroendocrine carcinoma (LCNEC) is rarely reported. Case presentation We report a case of a 49-year-old man presenting paraplegia caused by a metastatic urinary bladder LCNEC, which was managed with palliative external beam radiotherapy (EBRT) associated with MVAC chemotherapy, including methotrexate, vinblastine sulfate, doxorubicin hydrochloride (Adriamycin), and cisplatin. At the last follow-up of one year after his admission, there was a symptomatic improvement in the pain intensity. Conclusion LCNEC of the bladder was first described in 1986, and, until now, less than 40 cases have been published in the literature. To the best of our knowledge, this is the first case of primary LCNEC of the urinary bladder presenting with paraplegia.

Background chronic lymphocytic leukemia (CLL) patients have a high risk of occurrence of secondary cancers. This risk is three times higher for all cancers and eight times higher for skin cancer. The coexistence of CLL and adenocarcinoma of the prostate is rare. Case presentation We report a case of a66-year-old man who underwent radical prostatectomy for prostate carcinoma. The final histopathological diagnosis of Gleason 7 adenocarcinoma of the prostate with incidental Rai stage I chronic lymphocytic leukemia (CLL) was made. No further investigations or treatment was offered due to the age and low disease stage. At the last follow-up of 12 months, the patient is alive, without disease progression for both lymphoma and prostate, with a PSA value of 0.03 ng/ml. Conclusion Early detection of lymphoma after radical prostatectomy will allow optimal management. The analysis of this link requires, therefore, additional investigations.

Background Cardiac Hibernomas are very rare benign tumors and usually remain asymptomatic. Neonatal cardiogenic shock due to cardiac tumors is extremely very rare. Until this date a few cases of cardiac hibernoma have been reported in the literature. Transthoracic echocardiography help in the differential diagnosis, but the definitive diagnosis is histological. The management strategy is not clearly codified. The Aim is to report and discuss the clinical features of a cardiac Hibernoma and review the relevant literature. Case presentation We describe a case of a 2-day-old Caucasian full-term male neonate admitted in neonate intensive care with cardiogenic shock, having fluid resuscitation and inotropic drugs. Ventilatory support was started immediately with the subsequent reestablishment of normal blood pressure. Then he was transferred to the echocardiography laboratory. Transthoracic echocardiography showed two echogenic masses in the right atrium and right ventricle. The masses were extended to the pulmonary trunk. Pulmonary artery flow measurements showed the presence of pulmonary and tricuspid obstruction. Surgery was rapidly considered since the baby was hemodynamically unstable. Intraoperative evaluation showed a mass embedded in the interventricular septum that occupy the right ventricular cavity and the right atrium. The tumor involved also the chordae of the tricuspid. Partial resection was done. Tricuspid valve repair was performed by construction of new chordae from the autologous pericardium. The specimen was sent for histopathological analysis. The baby died immediately after surgery. Histological examination of the surgical specimen revealed clear multivacuolated cells filled with lipid droplets and granular intense eosinophilic cytoplasm which confirms the diagnosis of Hibernoma. Conclusion Cardiac Hibernomas are rare benign tumors. The prognosis and treatment strategy is closely dependent on the location, initial clinical presentation and possible complications. The prognosis can be unfavorable if the tumor was obstructive and infiltrate the myocardium.

Background The hydatid disease is a parasitic infestation caused by the larval stage of Echinococcus granulosus. The renal location of this infectious disease is uncommon compared to hepatic or pulmonary ones. Most patients remain asymptomatic for years and hydatiduria is the only pathognomonic clinical symptom. We report a rare case of renal hydatid cyst misdiagnosed and treated as a renal tumor. Case presentation A 45-year-old woman with no significant medical or surgical history presented with left lumber pain with hematuria. Magnetic Resonance Imaging (MRI) displayed a left renal mass with cystic and solid components, showing discreet enhancement, classified as Bosniak IV. The diagnosis of renal malignant tumor was made. The patient underwent a lumbotomy. Intraoperatively, the mass was adherent to the perirenal fat and seemed to invade the adrenal gland. An enlarged left nephrectomy with surrenalectomy was performed. The gross specimen showed a superior polar renal cyst (9 × 7 × 6cm). The cyst had a thick wall and contained multiple internal smaller cysts recalling the appearance of the hydatid cyst. The microscopic study showed a cyst wall consisting of acellular eosinophilic laminated membrane lined by a thin germinal layer from which merge daughter cysts. This cyst wall is surrounded by a dense fibrovascular tissue with chronic inflammatory cells. The diagnosis of renal hydatic cyst was made. Conclusion Although the renal hydatid cyst is relatively rare, this diagnosis must be considered in patients with renal cystic masses, especially endemic countries. Preoperative diagnosis is challenging, especially in type IV cysts which can mimic a renal tumor and lead to overtreatment.
