A case of cephalomelia discovered in a baby born in Niger
Résumé
Subcutaneous tumors with extra limbs are very rare, and they are considered either as fetus in fetu or fetiform teratoma. We report here the case of a 6-day-old presenting a mass extending at the level of the occipital bone. This mass is developed in the extracranial region and contains two forelimbs including hands with digits. CT shows that the squamous part of the occipital bone is involved with several defects through which a part of the cerebellum herniates. The boy was operated on and the tumor was removed. The herniated region of the cerebellum has also been removed. After surgery, the boy develops normally. This type of tumor is extremely rare and is only the second case that has been reported at this exact location. This could be the so-called c,phalom,lie described by Isidore Geoffroy Saint-Hilaire in a duck in his famous Treatise of Teratology (1836). The cause of this malformation is still a matter for debate.
