Wilms' tumor is one of the most frequent malignant neoplasms in childhood. Advances in treatment modalities such as the combination of chemoradiation therapy with surgery have enhanced overall survival. However, recurrence of Wilms' tumor is still a problem. In this case, a 28-year-old female had experienced intermittent abdominal pain, and the computed tomography scan showed a huge pelvic mass. The patient had a history of radical nephrectomy for Wilms' tumor with concurrent chemotherapy at the age of three. The pelvic mass was resected in February 2010 and was confirmed to be a recurrent Wilms' tumor. The recurrent tumor showed a classic triphasic Wilms' tumor growth pattern with frequent mitoses and tumor necrosis. Our case is an extraordinary case of a long-delayed recurrent Wilms' tumor after 25 years, which is the longest disease-free interval ever reported. The possible effects of chemotherapy as well as some other mechanisms of this late relapse are discussed.

A recent review of the literature identified more than 150 reported cases of pancreatoblastoma in children. However, the clinical, histological and therapeutic characteristics of this tumour are hardly known by most paediatric surgeons and oncologists. The clinical symptomatology is often discrete, such as abdominal pain and/or intestinal transit disturbances, and the revealing sign is usually the discovery of a voluminous abdominal mass. Pancreatoblastoma is most often located in the head or body of the pancreas but can be seen in any part of the pancreas. It forms a full mass, rather well encapsulated, round and soft in consistency, often large in size and that can develop beyond the limits of the pancreatic gland. The metastases may be present in the lymph nodes, liver, lungs and spleen. It is an embryonic organ tumour that morphologically resembles what the nephroblastoma or the hepatoblastoma are for the kidneys or liver, respectively. The pathological analysis characteristically shows two components in which cell density is often high: an epithelial component and a mesenchymatic component. The lab test evaluation should include an assay of alpha-foetoprotein. Elevated levels of this marker are often present in these tumours. An assay of this marker is therefore interesting, not only at the time of diagnosis, but especially for early diagnosis of relapses. The pancreatoblastoma treatment is above all surgical and only complete exeresis makes recovery possible. However, at the time of diagnosis, many patients are inoperable due to the extension of the tumour. The combination of cisplatin + adriamycin seems to be the most effective neoadjuvant chemotherapy regimen. Patients who have had an incomplete tumour exeresis pose a real problem due to the frequency of local relapses and/or metastases. Local irradiation is indicated in this case, as chemotherapy has not yet provided proven results in this context.

A 35-year-old man with a history of childhood Wilms tumor successfully treated with radiotherapy, chemotherapy, and surgery, collapsed and died unexpectedly in hospital following admission for abdominal pain. At autopsy, there was ischemic necrosis of the small intestine with altered blood within the stomach and small intestine. Within the upper abdominal aorta, there was patchy confluent calcific atherosclerosis with extension into the proximal superior mesenteric artery which was occluded by thrombus. Death was attributed to ischemic enteritis of the small intestine caused by mesenteric artery thrombosis complicated by gastrointestinal hemorrhage with aspiration. Localization of atherosclerosis to the radiation field with no significant atherosclerosis elsewhere and the young age of the decedent were supportive of radiation-induced atherogenesis. Geographically, localized atherosclerosis at autopsy in a tumor survivor should raise the possibility of a treatment-related side effect that may directly contribute to death many years after the original therapeutic intervention.

A previously healthy 18-year-old man was admitted to our hospital with abdominal pain in September 2010. We performed a percutaneous biopsy of multiple intrahepatic masses. A diagnosis of desmoplastic small round cell tumors was confirmed based on the presence of a polyphenotypic immunoprofile (positivity for EMA, vimentin, cytokeratin, desmin and WT1) and characteristic EWS-WT1 gene fusion. Because the mass had invaded the mesentery and the disease had disseminated to liver, the patient received palliative chemotherapy with carboplatin, paclitaxel, vincristine, doxorubicin, cyclophosphamide, ifosfamide, etoposide and irinotecan. The maximal response to the chemotherapy was a partial remission. The patient died 20 months after diagnosis.

Medical records of 30 children with renal tumor diagnosed at Siriraj Hospital during 1996 to 2007 were reviewed. Mean age at diagnosis was 36 months; male to female ratio was 1.7:1. Clinical manifestations included abdominal mass (96.7%), hypertension (40.0%), abdominal pain (36.7%), hematuria (26.7%), postrenal obstruction (16.7%), and proteinuria (13.3%). Eight patients had Denys-Drash malformations, WAGR, Dandy-Walker malformation, or genitourinary anomalies. Twenty-seven patients (90%) had Wilms tumor. Sixteen patients were stage 3 or more at diagnosis. Rhabdoid tumor was found in 3 patients. All patients received chemotherapy, 13 patients also received radiation therapy. Acute complications included febrile neutropenia (44.4%), hypokalemia (37.0%), hyponatremia (29.6%), Fanconi syndrome (11.1%), urinary tract Infection (10.0%), and acute renal failure (7.4%). Mean follow-up time was 57.2 months. Ten patients died from progressive disease. Five-year patient survival was 69.7%. Two patients had chronic kidney disease. One of these had Denys-Drash malformations. Both patients received ifosfamide-carboplatin-etoposide protocol and abdominal radiation. Antihypertensive medications were needed in 9 patients for a mean duration of 164 days. None had persistent proteinuria or hematuria. No difference was found among mean estimated glomerular filtration rate at diagnosis, 1 year after treatment, and at last follow-up. Long-term follow-up, especially renal function, is recommended.

Uterine tumors resembling ovarian sex cord tumors (UTROSCT) are rare neoplasms of unknown etiology. Only 67 cases have been reported in the literature, to our knowledge, so far. The neoplasm usually occurs in middle-aged women. Most patients present with abnormal uterine bleeding and/or abdominal pain, along with an enlarged uterus or a palpable uterine mass. There is no specific imaging finding, and the diagnosis is made exclusively on histopathologic examination. A multitude of architectural patterns are described, which include plexiform cords, anastomosing trabeculae, watered-silk, microfollicle, macrofollicle, tubules, retiform, solid cellular islands, and diffuse pattern of growth. The neoplastic cells are usually small with round to ovoid nuclei, nuclear monotony, mild nuclear hyperchromasia, and inconspicuous nucleoli with scant eosinophilic cytoplasm. Nuclear grooves are rare. Mitotic figures are infrequent, and necrosis is mostly absent. This tumor depicts a diverse immunohistochemical profile with expression of sex cord, epithelial, and smooth muscle lineages markers. Sex cord markers, such as inhibin, calretinin, CD99, WT1, and MART-1; epithelial markers, such as pancytokeratin and epithelial membrane antigen; smooth muscle markers, such as smooth muscle actin, desmin, and histone deacetylase 8; and miscellaneous markers, such as CD10, estrogen receptor, progesterone receptor, S100, and CD117, are often coexpressed. Immunoexpression for calretinin and at least for one of the other sex cord markers is required to establish a diagnosis of UTROSCT. Hysterectomy with or without bilateral salpingo-oophorectomy is usually the treatment for UTROSCT. Although most UTROSCTs behave benignly, some do recur, and thus, this entity should be considered as a tumor of low malignant potential. In this review, we discuss the current knowledge on UTROSCT and its clinical relevance.

The horseshoe kidney is the most common congenital renal fusion anomalies. It occurs in 0.25% of the population, or 1 in every 400 people. It is more frequent in males (ratio 2:1). The most observed complication of horseshoe kidney is stone disease, although there may be others such as, abdominal pain, urinary infections, haematuria, hydronephrosis, trauma and tumours (most commonly associated with hypernephroma and Wilms tumour). We describe a case of a male patient with horseshoe kidney, stone disease and adenocarcinoma of the prostate. One carrier of this condition who suffered a transitional cell carcinoma of the prostate was found in a review of the literature.

An 11.5-month-old male, diagnosed with bilateral Wilms tumor at 10 months of age, received 6 weeks of chemotherapy and subsequently underwent bilateral partial nephrectomies. On postoperative day 5, he had crampy abdominal pain and bilious vomiting. Abdominal ultrasound confirmed the presence of an intussusception in the right lower quadrant. Laparotomy demonstrated two separate areas of small intestinal intussusception located at jejuno-jejunal and ileo-ileal locations. The patient was successfully treated with manual reduction. A high index of suspicion is necessary to diagnose and treat patients with two different points of intussusception.

Wilms tumor is found in 1 in 10,000 children and most commonly presents in asymptomatic toddlers whose care givers notice a nontender abdominal mass in the right upper quadrant. This case of Wilms tumor presented as a critically ill eleven-year old with significant tachypnea, dyspnea, vague abdominal pain, intermittent emesis, new onset seizure, metabolic acidosis, and hypoxemia. This is the first case in the literature of Wilms Tumor with cavoatrial involvement and seizure and pulmonary embolism resulting in aggressive resuscitation and treatment. Treatment included anticoagulation, chemotherapy, nephrectomy, and surgical resection of thrombi, followed by adjunctive chemotherapy with pulmonary radiation.
