[Askin tumor: a case report with literature review]. / Tumeur d'Askin: à propos d'un cas avec revue de la littérature.

Askin tumor is a rare malignant tumor arising from soft tissues of the chest wall, rarely in the lung. It occurs predominantly in young adults. It still raises many questions about its individualisation and its links with Ewing's sarcoma. We report a case of Askin tumor in a 5-year-old child with reviewing the different data from the literature.
