Pediatric Rectosigmoid Atypical Juvenile Polyps Presenting With Rectal Prolapse and Acute Bleeding: A Case Report and a Comprehensive Literature Review.

Rectosigmoid solitary juvenile polyps are benign lesions, relatively frequent in childhood. The clinical debut of a pediatric polyp with bleeding is relatively frequent, but there are very few reports of rectal prolapse of polyps. We present the case of a 7-year-old female patient with no previous history who presented with rectal prolapse of a polyp with acute bleeding.

Superior Vesical Fissure as an Incomplete Form of Bladder Exstrophy: A Case Report with Clinico-Pathological Correlation and a Comprehensive Literature Review.

Multiple variants of classic bladder exstrophy have been described, all of them infrequent. Superior vesical fissure is a mild variant of this pathology in which genital involvement is scarce or absent. To date, there are only isolated reports of this entity.

Pediatric Vulvar Superficial Angiomyxoma: A Case Report With Clinical, Radiological, and Anatomopathological Characterization and a Comprehensive Review of the Literature.

Superficial angiomyxoma is characterized as a benign, slow-growing vascular cutaneous myxoma. A 6-year-old Arab girl with no medical history presented with a vulvar tumor located on the left labia majora. The lesion was present since birth, but it had significantly increased over the last 6 months.

Congenital Prepubic Sinus as a Variant of Incomplete Urethral Dorsal Duplication: A Case Report with New Insights into its Immunohistochemical Characterization and a Comprehensive Literature Review.

Congenital prepubic sinus (PS) is an extremely infrequent malformation consisting of a prepubic fistulous tract that classically does not communicate with the genitourinary system. Previous studies centered on its immunohistochemical characterization have shown inconsistent results, and the etiology has not been clarified. We present the case of a 2-year-old male who presented since birth with a fistulous orifice on the dorsum of the penis.

Gastric-phenotype Mucinous Carcinoma of the Fallopian Tube with Secondary Ovarian Involvement in a Woman with Peutz-Jeghers Syndrome: A Case Report.

Peutz-Jeghers syndrome is an autosomal dominant condition characterized by the association of hamartomatous polyps in the digestive tract, mucocutaneous pigmentation, family history, and infrequently tumors of the female genital tract with one of the most characteristic being the gastric-type endocervical adenocarcinoma. We present the case of a 75-year-old woman with a history of gastrointestinal polyps and cancer of the pancreas and breast, diagnosed with Peutz-Jeghers syndrome, who clinically debuted with a primary adnexal tumor. However, on histologic examination it was found to be a gastric-phenotype primary mucinous carcinoma tubal in origin, associated to tubal mucinous metaplasia and secondary ovarian involvement.

Crossed Testicular Ectopia: Report of Two Cases in Children of Consanguineous Parents.

Crossed testicular ectopia (CTE) is an extremely rare anomaly of urogenital development. The etiopathogenic mechanism is unknown. Medical records of two biological siblings with a confirmed diagnosis of CTE being managed at our center were collected.

Sentinel node tumor burden in cutaneous melanoma. Survival with competing risk analysis and influence in relapses and non-sentinel node status: retrospective cohort study with long follow-up in a Spanish population.

Several authors have studied the potential of sentinel lymph node (SLN) tumor burden as prognostic factor but the microscopic classifications used in different study groups were variable. We examined the prognostic role of tumor burden in SLN on melanoma specific-survival and competing causes of death. We also analysed clinical and histological factors as predictors of disease relapses and additional non sentinel lymph node (NSLN) metastases.

Description of the EuroTARGET cohort: A European collaborative project on TArgeted therapy in renal cell cancer-GEnetic- and tumor-related biomarkers for response and toxicity.

Objective: For patients with metastatic renal cell cancer (mRCC), treatment choice is mainly based on clinical parameters. With many treatments available and the limited response to treatment and associated toxicities, there is much interest in identifying better biomarkers for personalized treatment. EuroTARGET aims to identify and characterize host- and tumor-related biomarkers for prediction of response to tyrosine kinase inhibitor therapy in mRCC.

A type primary amyloidosis of the urinary bladder: Clinical case and bibliographic review.

Objective: Amyloidosis is a disease characterised by deposition of eosinophilic hyaline material in different tissues. Urinary bladder involvement is uncommon with less than 200 cases of the primary form published in the literature. We present a new case of primary AA type amyloidosis of the urinary bladder (typical of secondary forms).

[Malacoplakia of the testis: a new case report and a literature review].

Malakoplakia is a uncommon chronic granulomatous condition of a benign nature preferentially occurring in the genitourinary tract. Testes are affected in 12% of cases, and the first case of testicular malakoplakia was reported in 1958. Forty cases have been reported worldwide since that date.

[Collecting duct (Bellini) carcinoma].

Objectives: To report one case of collecting duct (Bellini) carcinoma and to review the national bibliography. To analyze the clinical, diagnostic, and therapeutic features of this malignant renal tumor.

Methods/results: A 36-year-old male presenting with monosymptomatic hematuria and clot retention was diagnosed of left renal mass suggestive of renal carcinoma.
