The primary intrarenal neuroblastoma (IRNB) is a rare condition. Intrarenal neuroblastoma typically results from direct renal invasion from an adrenal neuroblastoma, but true intrarenal neuroblastoma originates either sequestered adrenal rests during the fetal life or intrarenal sympathetic ganglia. Clinical, radiological, and pathological correlation is very essential for diagnosis and appropr...

Disseminated intravascular coagulation (DIC) is a complex clinical syndrome, described as a sequential activation of the coagulation and fibrinolytic system. Trauma and sepsis are some of the known precipitating factors. We report a case of nonovert disseminated intravascular coagulation presenting as a huge renal mass in a 3-year-old child, suspected to be a Wilms' tumor. On imaging studies, i...

Wilms tumor is an embryonal kidney cancer that affects one in 10 000 children. Epidemiologic studies have shown that 1%–3% of cases of Wilms tumor are familial and that a predisposition to Wilms tumor is probably caused by rare germline mutations acting in a dominant fashion (1). The risks of Wilms tumor conferred by mutations in these genes are poorly characterized, with estimates of their pen...

Familial Wilms tumor is a rare entity that accounts for only 1-2% of all Wilms tumor cases, with an earlier age of onset and an increased frequency of bilateral tumors. Teratoid Wilms tumor is a variant of nephroblastoma with a predominance of heterologous tissues comprising more than 50% of the tumor volume. Wilms tumor does not usually secrete any specific tumor marker and all teratoid Wilms ...

BACKGROUND Children with hemihypertrophy are screened for Wilms tumor, because this condition is a risk factor for developing the neoplasm. Patients with Klippel-Trenaunay syndrome (KTS) are often considered potential candidates for Wilms tumor, because they have unilateral overgrowth of the lower limb. In our experience, however, an association between KTS and Wilms tumor has not been observed...

epidermal nevus syndrome is a rare congenital disorder, characterized by epidermal nevi and multiple organ involvement. multicystic kidney disease has been very rarely reported in this syndrome. here is the report of a boy presented with multiple epidermal nevi, cardiac anomaly, seizure attack, hemi hypertrophy, and multicystic dysplastic kidney complicated with wilms' tumor. according to this ...

Wilms tumor is a primarily sporadic disease, with only 1–2 % of affected individuals having a relative with Wilms tumor. However, bilateral Wilms tumors occur in approximately 5 % of cases, and Wilms tumor has been reported in association with more than 50 different genetic disorders, pointing to an underlying predisposition in further individuals. There is conclusive evidence of an increased r...

A rare case of a Wilms tumor with intracardiac neoplastic extension is presented. The good prognosis of even extensive nephroblastoma is the reason for attempting a radical surgical approach to patients with intracardiac tumor thrombus. The exact preoperative delineation of the intracasal tumor extension is essential for a safe and successful operation. Ultrasonography in combination with echoc...
