RESUMO
Spinal neurofibroma is one of the rarest of the neoplasms involving the spinal cord or roots and occurs much less often than neurinoma, meningioma or glioma. The sixth pediatric case of solitary intramedullary tumor was described in 2013, according to B. Eljebbouri et al. We present a rare, difficult to diagnose and may-be the seventh pediatric case of solitary neurofibroma of the cauda equine in an 11-month-old infant. The patient underwent a laminectomy of T12, L1, L2 and L3, extirpation of intradural, intramedullary and extramedullary spinal cord tumor. The patient is fully recovered for 5 years of monitoring. Although rare, spinal neurofibromas in children should be diagnostically considered and radically treated for a favorable outcome.

BACKGROUND: Surgical treatment of odontogenic jaw cysts may include one of the following four basic methods: enucleation, marsupialization, staged combination of marsupialization and enucleation, or enucleation with curettage. Enucleation/cystectomy, alone or combined with other procedures, is the preferred choice of treatment. OBJECTIVE: The aim of the case report was to present the outcome of an ultrasound-assistant periapical cystectomy in a frontal upper tooth with indications for extraction. RESULTS: Postoperative recovery was uneventful. The functional result was satisfactory. On the follow-up X-rays a reduction of the intraosseous defect by a new bone formation could be observed. CONCLUSION: We found ultrasonic surgery to be a promising approach for safe and effective odontogenic jaw cyst removal reducing the risk of its recurrence.

Brown tumors are bony lesions caused by rapid osteoclastic activity, which rare involved jaws. Renal osteodystrophy (ROD) is associated with different pathogenetic mechanisms--disorder of calcium-phosphate metabolism, impaired metabolism of vitamin D, increased parathyroid activity that lead to extreme concentrations of parathormone. The authors report two cases of jaw enlargement in patients received haemodialysis with excessive increase values of alkaline phosphatase and parathormone in serum. The patients were treated surgically with corrective procedures in maxillo-facial area. ROD of the jaws could be severe complication in dialysis patients with end stage of CKD if no appropriate care aimed at correction or prevention of parathyroid hyperfunction was applied to them.
