Résumé
Soft tissue chondroma is a rare benign tumour, which is generally seen in adult. It consists of islands of heterotopic cartilaginous tissue and most localised on the hands and the feet. The hypothesis that microtrauma is involved in the aetiology of this condition has yet to find any factual support. To report two paediatric cases of soft tissue chondroma. The first is a soft tissue chondroma of the posterior aspect of the left axilla in a 3-year-old boy. CT scans showed a spherical fatty density soft tissue mass without evident calcifications, attaching the infraspinous muscle. The second patient is a 9-year-old girl presented with a right auricular finger soft tissue chondroma. Radiographs showed several punctuated calcifications with adjacent bone scalloping. MRI revealed a lobulated soft tissue mass attaching the flexor tendons. The tumours were entirely removed. Histological examination showed cartilaginous tissue in both cases. At follow-up, the patients had good functions without evidence of recurrence. Simple excision should suffice to treat soft tissue chondroma but care should be taken to make the excision complete if recurrence are to be avoided

Lipomatous tumours of the limbs in children are rare, and lipoblastoma is the most common soft tissue tumour. Most of them have typical imaging features, but their clinical presentation and their management may vary, depending on the exact histological subtype.The aim of our study is to illustrate the main clinical, radiological and histological features of the different benign lipomatous tumours in children. review of the literature. it is about a descriptive study of paediatric cases of benign lipomatous tumours of limb in children. The imaging findings are helpful and can provide essential components for the diagnosis

Recently, there have been several case reports of cavernous angiomas appearing after radiation to the brain, typically in children. The time interval between irradiation and the detection of the cavernous angioma varied from three to nine years and the doses from 24 to 60 grays. We report the appearance of a cavernous malformation in a young girl 3 years after radiation therapy for a brain tumor
