Congenital malignant tumors

Abstract

Nine cases of congenital malignant tumors are reported with special attention to significant histories, diagnosis and pathologic documentation. The cases include fibrosarcoma, neuroblastoma, reticulum cell sarcoma, undifferentiated sarcoma and malignant histiocytosis. The authors believe that congenital malignant tumors occur more frequently than the number of previously reported cases would suggest and allude to the scientific value in considering them as a group. Among the reported cases are an 11-year cure of neuroblastoma, death of a 6-month fetus due to undifferentiated sarcoma and the sixth reported case of orbital sarcoma. Diagnostic considerations of juvenile fibrosarcoma are discussed. A brief comment concerning each tumor is included, offering the physician pertinent clinical background and relative frequency of occurrence.
