Intralabyrinthine sporadic endolymphatic sac tumour
Discussion Endolymphatic sac tumours invade the posterior part of the petrous temporal bone. According to two studies concerning patients with Von Hippel-Lindau disease, endolymphatic sac tumours arise from the endolymphatic duct. This case of intralabyrinthine sporadic endolymphatic sac tumour supports this hypothesis for sporadic forms, indicating the need for labyrinthectomy associated with tumour resection to avoid recurrence.

A Rare Case of Pediatric Vaginal Yolk Sac Tumor
A 14-month-old girl was evaluated for intermittent vaginal bleeding. Vaginoscopy revealed a friable tumor, and biopsy results confirmed a yolk sac tumor. AFP was elevated (1386 ng/mL) at diagnosis but quickly normalized with chemotherapy. Twelve months after diagnosis, she remains tumor-free. Although rare, malignant tumors of the vagina must be included in the differential diagnosis of prepubertal girls who present with vaginal bleeding. Primary yolk sac tumor of the vagina is seen in girls less than 3 years of age and is treated with chemotherapy with or without surgical excision.

Relapse in children with clinical stage I testicular yolk sac tumors after initial orchiectomy
ConclusionsLVI and necrosis were independent risk factors for relapse in pediatric patients with CS1 testicular yolk sac tumors, and primary chemotherapy was effective. Thus, individualized management might be feasible for these patients according to risk classification.

Combined adenocarcinoma with yolk sac tumor of the rectum metastasizing as a germ cell neoplasm: Case report
We reported a case of 18 years-old female patient admitted to Mansoura oncology center with severe abdominal pain. Physical examination revealed a distended abdomen with hepatomegaly with no abdominal mass. Computed tomographic (CT) scan of the abdomen revealed markedly enlarged liver with multiple innumerable variable sized hyper-echoic non-enhanced focal lesions. The patient underwent an ultrasound- guided biopsy of the liver that showed metastatic yolk sac tumor. Colonoscopy confirmed a large polypoidal ulcerating mass that was 15 cm from anal verge. Biopsy from the mass revealed conventional colonic adenocarcinoma merg...

Unusual presentation, relapse and metastasis of a pediatric testicular yolk sac tumor: case report.
Testicular tumors are not uncommon in children and represent 1-2% of all pediatric malignancies. Prepubertal testicular yolk sac tumor is the most common childhood testicular cancer, accounting for 70-80% of all cases. The clinical presentation varies from one patient to another; most common presentation is painless scrotal mass. Herein, we present a case of pediatric patient with a testicular yolk sac tumor who had unusual presentation followed by a local relapse and metastasis and continued to have high markers while he was on chemotherapy, then underwent retroperitoneal lymph node dissection (RPLND) and local recurrence excision.

CT-Based Radiomics to Differentiate Pelvic Rhabdomyosarcoma From Yolk Sac Tumors in Children
ConclusionsThe CT-based radiomics model can be used to effectively distinguish RMS and YST, and combined with clinical features, which can improve diagnostic accuracy and increase the confidence of radiologists in the diagnosis of pelvic solid tumors in children.

Primary mediastinal yolk sac tumor: a case report and literature review.
This article reports a 42-year-old man with a primary mediastinal YST. The patient presented with chest tightness and shortness of breath. Using a contrast-enhanced computer tomography (CT) scan, the mediastinal space was found to be occupied by a mass shadow, about 10 cm × 8 cm with a clear boundary and low density. Serum alpha-fetoprotein (AFP) was elevated to 7169.66 ng/ml. The 5th day after hospitalization, a percutaneous biopsy of the mediastinal mass was performed. Malignant tumor cells were found by cytologic examination. According to the pathological morphology and immunohistochemical results, the tumor was diagno...

27. A Case of Vaginal Yolk Sac Tumor in an 8 Year Old Girl with Didelphys Uterus
We present a case where an initial exam under anesthesia revealed no evidence of a vaginal malignancy. However, due to ongoing symptoms, a re-evaluation revealed vaginal yolk sac tumor which had been concealed by a congenital anomaly.

The clinical features and prognostic outcomes of primary mediastinal yolk sac tumors: A retrospective analysis of 15 rare cases from multiple centers
In this study, we aimed to provide further information relating to this rare malignancy in order to facilitate the creation of more specific clinical guidelines for the diagnosis and treatment of patients with PMYSTs. In this retrospective study, we recruited 15 patients who had been diagnosed with PMYST from four medical institutions to create a population-based cohort. We then used Kaplan-Meier analysis and the log-rank test to investigate and compare overall survival (OS) and progression-free survival (PFS). A total of 15 cases were identified. The mean age was 27.3 years (range: 19–34 years). The estimated ...

Post-treatment Residual Clinicopathological Outcomes in Testicular Germ Cell Tumours
AbstractSurgical resection is a generally accepted treatment for residual masses after chemotherapy for metastatic testicular germ cell tumour (GCT). About half the patients have necrosis in post-chemotherapy residual masses, whereas rest have viable tumour and teratoma. The likelihood of leaving behind teratoma with its subsequent complications such as growing teratoma syndrome necessitates resection outweighing its surgical complications. Ours is a retrospective observational study and aims at assessing post-chemotherapy residual masses in testicular GCTs and to predict importance of teratomatous and non-seminomatous com...
