A 6-month-old girl was admitted to another hospital because of consciousness disturbance, preceded by 2 weeks of decreased activity and vomiting. She was referred to our hospital after ventricular drainage had been instituted for hydrocephalus and the tumor in the pineal region. The patient was noted to have conjugate upward gaze palsy and papilledema. CT scan and MRI revealed a large tumor in the pineal region with tumoral hemorrhage and a small mass in the right frontal lobe. At surgery, the pineal region tumor was removed subtotally. Histological examination showed the tumor to be composed of sheets of large polyhedra or round cells with an eccentric round nuclei, prominent nucleoli, and cytoplasmic inclusions. Immunohistochemical studies were positive for GFAP, vimentin, S-100, CK, EMA, and SMA, but negative for AFP, HCG, PLAP, and CEA. Following surgery, she received three 5-day cycles of chemotherapy, consisting of intravenous administration of cisplatin 20 mg/m2/day and etoposide 60mg/m2/day. After these therapies, MRI showed a decrease in the area of high intensity in the pineal region, but almost no change in the right frontal mass lesion. Follow-up radiological examination showed that the tumor had grown rapidly one month after chemotherapy and the patient died 5 months after her first hospitalization. Malignant rhabdoid tumor of the CNS is rare and remarkably malignant. This tumor should be treated using multidisciplinary management with surgery, intensive chemotherapy, and radiotherapy depending on the patient's age.

Diffuse malignant peritoneal mesotheliomas in children are uncommon, aggressive tumors with a grave prognosis. We herein report the clinical, radiologic, and pathologic findings of a 16-year-old male. The adolescent presented with a history of abdominal pain, nausea and daily, nonbilious, nonbloody emesis for 3 weeks. Radiographic imaging suggested small bowel obstruction. The diagnostic work-up and differential diagnoses are discussed. Histologically, the tumor was composed of epithelioid cells with a papillary and glandular architectural pattern. A few glands appeared to produce mucinous material. Histochemistry revealed PAS diastase resistant mucin, an inconspicuous finding in diffuse malignant peritoneal mesothelioma. An extensive immunohistochemistry panel (calretinin, WT-1, D2-40, CK 7, CAM 5.2, CK 5/6, CEA, B72.3, CK 20, CD10, CD30, CD15, CD117, PLAP, S100, TFE3, and EMA) confirmed the diagnosis. Of special interest, BAP1 staining was cytoplasmic and consistent with 3p deletion detected by conventional cytogenetics. The ultrastructural analysis demonstrated long microvilli, desmosomes, and intercellular junctions which further supported the diagnosis.
