Treatment of infantile fibrosarcoma: A tertiary care center experience

Abdominal wall congenital infantile fibrosarcoma: A rare case report and literature review

Congenital infantile fibrosarcoma is a rare malignant soft tissue tumor, accounting for less than 1%-2% of childhood cancers. Although it can arise from any body part, an abdominal wall origin is exceptionally rare. This case report presents a case of congenital infantile fibrosarcoma originating from the abdominal wall. To the best of our knowledge, this is only the second reported case of abdominal wall congenital infantile fibrosarcoma. Unlike adult fibrosarcoma, infantile fibrosarcoma has a good prognosis with less metastasis. Early diagnosis and management are critical for improving outcomes in such rare cases.

Pediatric orbital lesions: neoplastic extraocular soft-tissue lesions

Pediatric neoplastic extraocular soft-tissue lesions in the orbit are uncommon. Early multimodality imaging work-up and recognition of the key imaging features of these lesions allow narrowing of the differential diagnoses in order to direct timely management. In this paper, the authors present a multimodality approach to the imaging work-up of these lesions and highlight the use of ocular ultrasound as a first imaging modality where appropriate. We will discuss vascular neoplasms (congenital hemangioma, infantile hemangioma), optic nerve lesions (meningioma, optic nerve glioma), and other neoplastic lesions (plexiform neurofibroma, teratoma, chloroma, rhabdomyosarcoma, infantile fibrosarcoma, schwannoma).

Paediatric fibrosarcoma treatment

Introduction

Soft tissue sarcomas make up 7%-15% of childhood solid tumours. The aetiology of this disease is unknown. It is a fast-growing, painless tumour; histologically similar to adult fibrosarcoma, but having a lesser risk of metastasis and a better prognosis. The treatment is aimed towards localised intervention; complete surgical resection is the appropriate treatment as long as it can be performed.

Case report

An 11 years old female was referred for resection of a soft tissue tumour on the right elbow with significant peripheral vascularisation. Tumour resection was scheduled, with the placement of a partial thickness skin graft, and a piece was sent to pathology; a histological type consistent with paediatric fibrosarcoma was obtained with margins less than 1 mm from the lesion. Therefore, the patient was referred to the paediatric oncology unit. Further studies with positron emission tomography were requested, in which no evidence of macroscopic anatomy-metabolic tumour activity was found. Subsequently, treatment was started by paediatric oncology with 2 sessions of chemotherapy and 20 sessions of radiotherapy with sufficient progress; finally, assessment by plastic and reconstructive surgery was performed and an adequate quality of graft was observed, without the need for any other intervention by their service.

Conclusion

The involvement of the vascular surgeon in performing the tumour resection permitted the preservation of the best circulation to the extremity, thereby, avoiding amputation. The difficult decision made by the reconstructive surgeon to place a partial thickness graft over the surgical site, and to start radiotherapy/chemotherapy by paediatric oncology, were key to the success in achieving the patient's satisfactory progress.
