Extracranial congenital malignant rhabdoid tumor in infant with disseminated disease: An uncommon entity and diagnostic challenge

Malignant rhabdoid tumors (MRTs) are uncommon and aggressive tumors that typically present during childhood. Primary MRTs most often arise from the central nervous system and kidneys; however, primary tumors from other sites are occasionally reported. We present a case of an infant born with extracranial MRTs who was found to have disseminated disease involving the abdominal viscera.
