Abstract

Abstract: Background: We present the diagnostic dilemma of a neonate with two umbilical soft tissue masses. Case report : The baby had an umbilical mass herniating through the umbilical cord, and another mass hanging from the umbilical mass by a string of tissue. Both masses were amorphous solid soft tissues and the hanging mass had hair on the surface. Clinical diagnosis was umbilical cord teratoma. However, histopathological examination of the masses showed that tissues representing various organs were arranged in cephalocaudal order as in a fetus, revealing that it was a parasitic twin. The hanging mass was probably the cephalic part and the umbilical mass was malformed torso and limbs. Conclusion : This parasitic omphalopagus heteropagus parasitic twin presented as two amorphous masses without externally identifiable anatomic structure, The parasitic twin of omphalopagus heteropagus may have unusual presentations. Histopathological examination was essential to diagnose whether it is a twin or a tumor.
