Histiocytome fibreux angiomatoïde de l'enfant : 6 cas

In our series, a diagnosis of AFH had in no event been evoked after clinical examination and radiological investigation. The diagnosis was based in all cases on recognition of characteristic features during histological examination and it was confirmed in 3 cases by the recognition of fusion genes. Complete excision with wide margins allowed complete cure in all cases, supporting a good prognosis of AFH, although long-term follow-up is still mandatory to rule out relapse or metastases, which although rare, are responsible for fatal cases. To avoid unnecessary surgery in patients with AFH, an ultrasound core-needle biopsy should be performed as a first step in order to provide precise diagnosis enabling complete excision to be performed, with the margins being decided in multidisciplinary meetings involving teams specialised in soft-tissue tumours.
