[Angiomatoid fibrous histiocytoma in children: 6 cases].

Background: Angiomatoid fibrous histiocytoma (AFH) is a soft-tissue tumour of uncertain differentiation most often arising in the extremities of children and young adults. AFH is a little-known neoplasm and its rarity may result in it being misdiagnosed as either a reactive lesion or a benign or higher-grade tumour. We report 6 cases of AFH in children and we review the clinicopathological and molecular features of this neoplasm published in the literature.

[Clinical features of Spitz naevus in children: a retrospective study of 196 cases].

Aims: To better define the characteristics of Spitz naevus (SN) in children, to determine whether it was clinically diagnosed and to examine the differential diagnoses made according to age. In addition, to determine whether atypical spitzoid tumors (AST) have a different presentation from other forms of SN.

Patients And Methods: A two-centre retrospective survey was made of histopathological reports written over a 4-year period in children aged under 18 years.
