Extraneural recurrence of an intracranial nongerminomatous germ cell tumor to cervical lymph nodes in a pediatric patient: Case report.

Background: Intracranial germ cell tumors (GCTs) comprise 3%-5% of pediatric primary central nervous system (CNS) tumors in Western countries. Though they are related in embryonic origin to gonadal GCTs, which are considered highly treatable with cisplatin-based chemotherapy regimens, intracranial GCTs vary in malignant potential and sensitivity to radiation and chemotherapy, generally carrying a worse prognosis. Metastases of intracranial GCTs outside of the CNS are rare, indicate a poor prognosis, and their salvage treatment is not well established.

Venous thromboembolism in pediatric patients: epidemiologic data from a pediatric tertiary care center in Alabama.

Venous thrombosis is an infrequent but serious cause of hospitalization in children. The epidemiology and natural history remains incompletely defined, especially in geographically distinct regions of the United States. We thus evaluated thrombosis in a single children's hospital over a 3-year period.

Sirolimus therapy for fibromatosis and multifocal renal cell carcinoma in a child with tuberous sclerosis complex.

A male with tuberous sclerosis complex (TSC) developed a chest wall fibromatosis and bilateral multifocal renal cell carcinoma (RCC). The fibromatosis tumor was initially resected during infancy but recurred 5 years later. At that time, bilateral RCC was also detected, leading to the resection of the more extensively affected right kidney.
