M. was a one-day-old, white male with multiple congenital anomalies. His mother was gravida I, para I, aborta O. Her pregnancy was complicated by a 16 kg weight gain and she had taken diuretics and vitamins during the fifth month of pregnancy. The infant had a normal vertex delivery at 33 weeks' gestation and a normal amount of amniotic fluid was present. Birth weight was 2.7 kg; head circumference of 33.0 cm, chest circumference of 30.0 cm. The optic fundi were unremarkable. The ears were low set, the nose flattened and beaklike, and mild micrognathia was present, characteristic of a Potter's facies (Fig. 1). The lungs were clear and no cardiac murmurs were heard. The abdomen was protuberant with smooth masses palpable bilaterally in the flanks. The testes could not be palpated. The hands were broad and spadelike, with a skin tag attached to the fifth digits. There were bilateral talipes equinovarus deformities, with polydactaly and webbing of the toes. The baby had good Moro, grasp, and suck reflexes, but had a somewhat weak and high-pitched cry. Initial hematologic values were normal as was the urinanalysis. Blood urea n i t r o g e n was-10 mg, and s e r u m creatinine was 0.9 mg/dl. The chest radiograph was unremarkable. An initial intravenous pyelogram revealed bilateral renal enlargement with marked distortion of the pelvocalyceal collecting systems. On the right side, a collection of contrast medium in the superior pole of the kidney was thought to be in dysplastic tubules rather than in a definable superior pole calyx. The kidneys were not considered to be hydronephrotic.
Fig. 2. Bilateral retrograde pyelogram. Attempts to pass a retrograde catheter into the left renal pelvis were unsuccessful with the catheter coiling upon itself in the proximal ureter. The left kidney was hydronephrotic. The distal left ureter was deviated to the right and was compressed by the enlarging lower pole of the left kidney. A large polypoid mass was demonstrated occupying the entire right renal pelvis and causing severe distortion of the pelvocaiyceal collecting system. At 3 weeks of age, the left kidney had increased markedly in size. Another IVP showed severe hydronephrosis of the left kidney but no change of the right one. Cystoscopy and retrograde pyelograms at this time revealed a large polypoid mass which occupied the pelvocalyceal collecting system of the right kidney. On the left, marked hydronephrosis was present secondary to partial obstruction of the ureteropelvic junction. The left ureter was deviated to the right by the enlarged lower p01e of the left kidney (Fig. 2). At laporatomy a large u n r e s e c t a b l e mass filled the pelvocalyceal collecting system of the left kidney, causing proximal obstruction of the left ureter. On the right side, a similar mass was found but without obstruction. Frozen sections of the masses were diagnosed as bilateral Wilms' tumor. The extent of the tumor precluded any definitive surgery. Bilateral nephrostomy tubes were inserted and the abdomen was closed. Later routine examination of tissues from both kidneys confirmed the diagnosis. On the ninth postoperative day there was a gastrointestinal hemorrhage requiring transfusions with fresh whole blood.

Despite continuing supportive care, the child died at 5 weeks of age. PATHOLOGY The pathologic changes were limited to the kidneys. The left kidney was enlarged; it weighed 51 gin. Bisection revealed a hemorrhagic mass which occupied the entire upper renal pole and the midportion of the renal parenchyma; there were polypoid projections into the pelvis. The right kidney contained a mass similar to the one on the left. The right pelvic mucosa was grossly normal. M i c r o s c o p i c a l l y the t u m o r and r e n a l p a r e n c h y m a were clearly separated in the medulla by bands of connective tissue which had the characteristics of a tumor pseudocapsule (Fig. 3, F ) . Normal renal tubules were engulfed by neoplasm at the junction of the tumor (Fig. 3, F). The mass was edematous, papillomatous, hemorrhagic, and focally necrotic. The external tumor surface
was entirely covered by pelvic epithelium (Fig. 3, A). The tumor was composed of islets of hematoxophilic epithelial tissue with scanty cytoplasm separated mainly by myxomatous or occasionally more cellular fibroblastic tissue (Fig. 3, B). N o cartilage was seen. The cells of the epithelial areas possessed hyperchromic nuclei (Fig. 3, C) with a fine chromatic pattern, and occasional nucleoli. In some areas, these cells formed primitive t u b u l e s with a c e n t r a l l u m e n (Fig. 3, D), b u t no neoplastic glomerular formations were seen. The tissue t h a t s u r r o u n d e d t h e a b o v e islets was c o m p r i s e d of elongated cells, with scarcely visible eosinophilic cytoplas m and with larger, less h e m a t o x o p h i l i c n u c l e i than the epithelial cells (Fig. 3, E ) . No intravascular tumor was seen in any of the multiple sections examined. The normal renal parenchyma showed variable mat u r i t y o f the g l o m e r u l i , b u t w i t h o u t tissue characteristics of Wilrns' tumor.

Fig. 4. Translocation between a C chromosome to a B chromosome. CYTOGENETIC STUDIES Peripheral lymphocytes were cultured for chromosome analysis. Thirty cells were analyzed and in all the cells the modal chromosome n u m b e r was 46 with an increase in length of the long arm of one of the B group chromosomes. In one of the C group chromosomes there was a deletion of portions of the long arms (Fig. 4). The mother refused to have chromosomal analysis; the father is u n k n o w n . The cytogenetic findings in the patient were interpreted as a translocation between one of the long arms of a B chromosome and the long arms of a C chromosome (Fig. 4). Giemsa banding techniques, in an attempt to identify the specific chromosome involved, were inconclusive. DISCUSSION The pathologic features that differentiate W i l m s ' tumor from benign mesoblastic hephroma have been clarified by Bolande and associates I Differentiation between the two neoplasms is of obvious therapeutic and prognostic importance. This infant had bilateral congenital Wilms' tumor, B-C chromosomal translocation, Potter's facies, a n d talipes e q u i n o v a r u s , polydactaly, webbing of the toes, and broad, spadelike hands without oligohydramnios.
There has b e e n little data to suggest c o n s i s t e n t chromosomal abnormalities in association with Potter's facies. P a s s a r g e a n d S u t h e r l a n d 8 f o u n d a n o r m a l chromosomal pattern in three patients with Potter's facies. T h e r e are two reports of a b n o r m a l c h r o m o somes in infants with Pottei"s facies, one with a Y-21 translocation9 and one with XX sex chromosomes and male external genitals; :~ our patient is the third case with c h r o m o s o m a l a b n o r m a l i t i e s . This paucity of chromosomal studies may reflect the u n c o m m o n occurrence of the syndrome or the frequency of stillbirth or of early death. Our patient may represent an isolated combination of chromosomal abnormalites of Wilms' tumor or may suggest a more common association.

AND METHODS
Clinical. Forty-one patients were studied. Twentythree children with genetic short stature, three adults and one adolescent who had acromegaly, and two Abbreviations used GH: growth hormone IRI: immunoreactive insulin IRGH: immunoreactive growth hormone IM: intramuscular IV: intravenously children with hypopituitarism were given IV glucagon. The five girls and 18 boys were 3 6/12 to 15 9/12 years of age. None was obese. Bone maturation was assessed by the standards of Greulich and Pyle. Skeletal age excluded evidence of hypothyroidism. Growth velocity curves (calculated in cm/year) excluded evidence of growth hormone deficiency. All patients had normal adrenal and thyroid functions. Twelve other patients (10 boys, 2 girls) had IM glucagon tests. Chronologic ages ranged from 1 3/12 to 10 8/12 years. Bone ages were comparable to height ages. None was obese or malnourished. Growth velocities ranged from 2.4-9.0 cm/year. The four acromegalic patients consisted of one 13year-old girl, reported elsewhere, 9 and three adult pa-

AND METHODS
Clinical. Forty-one patients were studied. Twentythree children with genetic short stature, three adults and one adolescent who had acromegaly, and two Abbreviations used GH: growth hormone IRI: immunoreactive insulin IRGH: immunoreactive growth hormone IM: intramuscular IV: intravenously children with hypopituitarism were given IV glucagon. The five girls and 18 boys were 3 6/12 to 15 9/12 years of age. None was obese. Bone maturation was assessed by the standards of Greulich and Pyle. Skeletal age excluded evidence of hypothyroidism. Growth velocity curves (calculated in cm/year) excluded evidence of growth hormone deficiency. All patients had normal adrenal and thyroid functions. Twelve other patients (10 boys, 2 girls) had IM glucagon tests. Chronologic ages ranged from 1 3/12 to 10 8/12 years. Bone ages were comparable to height ages. None was obese or malnourished. Growth velocities ranged from 2.4-9.0 cm/year. The four acromegalic patients consisted of one 13year-old girl, reported elsewhere, 9 and three adult pa-
