Self extrusion on an ingested foreign body: a case report.

Foreign body ingestion is a frequent issue in paediatrician's practice. Foreign bodies often pass the gastro-intestinal tract spontaneously but can sometimes generate complications (1% of the cases). The migration of ingested foreign bodies is rare, but their spontaneous extrusion through the skin is even rarer and was previously described only in the neck.

Rare retro peritoneal tumor in infants.

Lipoblastoma is a rare mesenchymal tumor, occuring in less than three-year-old infants in 90% of the cases and in 40% of the cases in chidren aged less than one year. It can be present at birth. It is a benign tumor, with defined margins, that can be locally aggressive, without metastases.

Community acquired methicillin-resistant Staphylococcus aureus preseptal cellulitis complicated by zygomatic osteomylitis, cavernous sinus thrombosis and meningitis in a healthy child.

We report a case of community-acquired meticillin-resistant Staphylococcus aureus (CA-MRSA) preseptal cellulitis complicated by zygomatic osteomyelitis, cavernous sinus thrombosis, meningitis, and necroziting pneumonia in a previously healthy two and half month old girl. This case exemplifies an aggressive and disseminated CA-MRSA infection with deep venous thrombosis in an infant without predisposing risk factors. The literature is reviewed and recommendations for management are provided.

[Granulocytic sarcoma of the maxillary sinus: a pediatric case report].

Background: Granulocytic sarcoma is a rare malignant extramedullary neoplasm of myeloid precursor cells, occuring before or after onset of leukaemia. Involvement of the head and neck region is rare, generally concerning the orbit.

Aim: To illustrate imaging findings of granulocytic sarcoma in an unusual location; maxillary sinus.

Pyelonephritis xanthogranulomatous in childhood: case report and literature review.

Background: Xanthogranulomatous pyelonephritis (XGP) is a specific form of chronic inflammatory kidney disease rarely seen in children. The Symptoms are often vague and non-specific

Aim: the aim of this paper is to return the particularities of imaging features in xanthogranulomatous pyelonephritis, insisting on differential diagnosis with renal tumors, especially in case of no renal stone or tract obstruction evidence.

Case: We report a case of xanthogranulomatous pyelonephritis in a 2-year-old boy involving the lower renal pole which demonstrates the diagnostic difficulties encountered in this disease

Conclusion: Xanthogranulomatous pyelonephritis is a rare condition in children and should be included in the differential diagnosis of a child presenting a renal mass.

Magnetic resonance evaluation of acetabular residual dysplasia in developmental dysplasia of the hip: a preliminary study of 27 patients.

Thirty-one hips in 27 young girls, treated for developmental dysplasia of the hip in the authors' institute since 2003, showed persistent radiographic evidence of residual acetabular dysplasia. These hips were registered as candidates for pelvic osteotomy. A prospective study was conducted and these hips were evaluated by magnetic resonance imaging (MRI); the average age of the patients was 5 years.
