[Intra renal teratoma. Study of a case in an infant (author's transl)].

Solid, intra renal tumors of children and infants are in most cases nephroblastomas. All the other types of solid tumors, malignant or benign, are very rare. This observation seems to be the seventh case of intra renal teratoma in the literature. The entire upper pole of the left kidney had disappeared, being occupied by a large tumor which proved to be solid upon specific examinations. Anatomo-pathologic examination, following nephrectomy, proved it to be benign.
