Rhabdoid tumors of the brain are rare with an invariable dismal prognosis despite treatment. This is the case of a 3 year old boy who presented lethargy, somnolence, nausea, vomiting, and headaches one week prior to hospitalization. A posterior fossa tumor with hydrocephalus was noted on a head computed tomography (CT) scan. A ventriculoperitoneal shunt was placed with subsequent gross total tumor resection. Pathology findings were those of a rhabdoid tumor. The histopathology, immunohistochemistry and ultrastructure of this unusual pediatric cerebral neoplasia is discussed.

We present a rare case of necrotizing fasciitis in an 5-year-old infant with preexisting varicella infection. Initially, the patient showed acute pain and swelling of the left thorax with high inflammatory parameters and varicella-specific skin affections. MRT presented diffuse soft tissue swelling of the left chest consistent with necrotizing fasciitis. After aggressive surgical debridement of necrotic tissue and extirpation of axillary lymph nodes, the clinical course improved under appropriate parenteral antimicrobial therapy using penicillin and clindamycin. In conclusion, necrotizing fasciitis should be suspected in any child with a history of varicella infection and increasing complaints of pain and swelling in an extremity or other body area associated with increasing fever, erythema, lethargy, and irritability. Shock, multiorgan failure, and death will ensue if the diagnosis is not promptly recognized.

This retrospective study aimed to evaluate the safety and toxicity of intrathecal liposomal cytarabine (Depocyte) in children and adolescents with refractory or recurrent brain tumors. Nineteen heavily pretreated patients (males, n = 14; females, n = 5; median age at diagnosis 8.5 years; range, 1.4-22 years) were given intrathecal liposomal cytarabine on a compassionate use basis for recurrent refractory medulloblastoma (n = 12), mixed germ cell tumor (n = 2), central nervous system primitive neuroectodermal tumors of the pons (n = 1), anaplastic ependymoma (n = 1), anaplastic oligodendroglioma (n = 1), atypical teratoid rhabdoid tumor (n = 1), or rhabdoid papillary meningioma (n = 1). Eighteen patients received concomitant systemic radiochemotherapy. A total of 88 intrathecal injections of liposomal cytarabine (dose range, 20-50 mg) were administered with concomitant dexamethasone prophylaxis. The median number of doses per patient was four (range, 1-10). Duration of treatment ranged from (1/2) to 10 months. Eleven patients (57.9%) did not show any side effects, whereas eight patients (42.1%) developed side effects related to either chemical arachnoiditis (n = 4) or neurological progression (n = 2). Less typical treatment-related symptoms (e.g. lethargy, ataxia, and slurred speech) were observed in two patients. Treatment with intrathecal liposomal cytarabine was discontinued twice because of side effects. In conclusion, although intrathecal liposomal cytarabine was generally well tolerated, it should be used cautiously and only with dexamethasone prophylaxis in extensively pretreated patients with recurrent brain tumors. Proof of efficacy requires a prospective single-agent phase II study.

Atypical teratoid rhabdoid tumor (ATRT) is a rare, highly malignant tumor of the central nervous system, commonly affecting children below 3 years of age, with around 300 cases reported in the literature. Suprasellar area is a very rare location for such tumor in the pediatric population, with technical difficulties in complete excision. Third ventricular ATRT is very rare. Here, we report the case of a 2-year-old male child who presented with lethargy and vomiting. He had features of raised intracranial pressure with reduced vision in both eyes. Magnetic resonance imaging of the brain revealed a heterogeneously enhancing lobulated giant lesion in the suprasellar location, occupying the third ventricle and hypothalamus with encasement of both carotids. He underwent pericoronal parasagittal craniotomy, interhemispheric transcallosal interforniceal approach and gross total excision of the lesion. Postoperatively, the child had altered sensorium and diabetes insipidus, both of which recovered over a span of 10 days. Histopathological examination of the specimen was consistent with the diagnosis of World Health Organization Grade IV ATRT. In spite of all our efforts, he succumbed to his illness 5 months postoperatively.

Malignant rhabdoid tumor of the kidney (MRTK) is a rare neoplasm of infancy. We report a case of a nine-month-old male infant who presented to the pediatrics outpatient department with the history of fever, lethargy, and abnormal head movements. On gross examination, the patient had a firm, non-tender, intra-abdominal mass at the right lumbar region with irregular margins. Computed tomography scan of the abdomen revealed a lobulated soft tissue arising from the kidney with areas of necrosis. Brain magnetic resonance imaging was also performed, which showed a large heterogeneous lesion in the posterior fossa. Histopathologic study revealed loss of INI1 protein. Since MRTK and atypical teratoid rhabdoid tumor (ATRT) of the brain share a common mutation in the gene (hSNF5/INI1), hence a diagnosis of MRTK with co-existent ATRT of the brain was established. Actinomycin-D and vincristine failed to show any improvement and the condition of the patient deteriorated progressively, resulting in his death within 15 days of hospital admission.
