The authors report four cases of arterial priapism in the child, a rare condition since only 13 cases are described in the literature. High-flow priapism follows perineal or penile injury with damage to a cavernosal artery and formation of an arteriosinusoidal fistula. The onset may be immediate but more often occurs after a few days. Arterial priapism is painless, as the corpora cavernosa are less tumescent in the anterior third of the penis. The clinical appearance and circumstances of onset suggest the diagnosis. Doppler ultrasound is the complementary investigation of choice, confirming and localising the fistula. Various methods of treatment have been proposed. Injections of alphastimulant seem ineffective in most cases and are not without danger. Surgery, which is potentially damaging, has been used only in the adult. Most authors propose embolising with resorbable material the artery which feeds the fistula. However, priapism may resolve spontaneously in less than three weeks, as occurred in our cases, without recurrence or subsequent erectile dysfunction. We thus consider the condition may initially be managed by observation alone, with recourse to embolisation if priapism does not resolve after a period of time which however remains to be defined.

We describe two cases of giant-cell fibroblastoma (GCF) with dermato fibro sarcoma protuberans (DFSP) component, occurring in two children in a chest wall localization. One case recurred 1 year later. The two patients were tumor-free 12 and 8 years later. GCF is a rare mesenchymal cutaneous and subcutaneous tumor reported mostly in the first two decades of life. Dermato fibro sarcoma protuberans, occurring preferentially in adults, is a rare skin tumor with a pronounced tendency to local recurrence. Some cases of association of recurrence of GFC under the form of DFSP have been reported, raising the question of a continuum between the two tumors. The treatment of choice of the two tumors is a wide local excision.
