title: Congenital orbital and disseminated extrarenal malignant rhabdoid tumor.
abstract: A 5-week premature infant boy with tumorous malformations underwent biopsy of two truncal masses and exenteration of the left orbit. Specimens were examined histologically. Histologic reports, slides, and clinical photographs were reviewed. A diagnosis of malignant rhabdoid tumor was made. Malignant rhabdoid tumors can present as local or disseminated neoplastic disease involving the orbit and should be considered in the differential diagnosis of rapidly progressing orbital lesions presenting in early infancy. We review the current classification of rhabdoid tumors and the previous literature on orbital rhabdoid tumors.
