FETAL ADRENAL GLAND AND KIDNEY Figure 1-4 FETAL ADRENAL GLAND AND KIDNEY Coronal sections (left and right) of adrenal gland and kidney from a fetus of about 18 weeks’ gestational age. External aspect of one specimen is at bottom. Medullary tissue is not evident macroscopically at this early More about this image found in FETAL ADRENAL GLAND AND KIDNEY Coronal sections (left and right) of adrena...

FETAL ADRENAL GLAND AND KIDNEY Figure 1-5 FETAL ADRENAL GLAND AND KIDNEY Coronal section of adrenal kidney and adjacent tissue from a fetus at approximately 11 weeks’ gestational age. The developing para-aortic sympathetic plexus has a close relationship with the medial and inferior aspects More about this image found in FETAL ADRENAL GLAND AND KIDNEY Coronal section of adrenal kidney and adjac...

ANATOMIC RELATIONSHIPS OF FETAL ADRENAL GLANDS Figure 1-6 ANATOMIC RELATIONSHIPS OF FETAL ADRENAL GLANDS Transverse section of upper abdomen in a fetus of about 10 weeks’ gestational age. Liver is at the top left side of the image, pancreas at top right. The developing para-aortic and preaortic More about this image found in ANATOMIC RELATIONSHIPS OF FETAL ADRENAL GLANDS Transverse section of upper...

NEUROBLASTIC NODULES AND MATURING MEDULLARY PROGENITORS IN DEVELOPING FETAL ADRENAL GLAND Figure 1-11 NEUROBLASTIC NODULES AND MATURING MEDULLARY PROGENITORS IN DEVELOPING FETAL ADRENAL GLAND Fetal cortex with interspersed aggregates of immature cells with varied sizes and cytologic features More about this image found in NEUROBLASTIC NODULES AND MATURING MEDULLARY PROGENITORS IN DEVELOPING FETAL...

TYROSINE HYDROXYLASE IN DEVELOPING FETAL ADRENAL GLAND Figure 1-13 TYROSINE HYDROXYLASE IN DEVELOPING FETAL ADRENAL GLAND Most of the medullary progenitor cells in this image express TH. Because TH is a cytosolic enzyme, it can often detect ability to produce catecholamines in immature or poorly More about this image found in TYROSINE HYDROXYLASE IN DEVELOPING FETAL ADRENAL GLAND Most of the medulla...

S-100 PROTEIN IN DEVELOPING FETAL ADRENAL GLAND Figure 1-14 S-100 PROTEIN IN DEVELOPING FETAL ADRENAL GLAND Some S-100 protein-positive cells are present at the periphery of a small neuroblastic aggregate (right), while others are associated with scattered more mature-appearing cells with clear More about this image found in S-100 PROTEIN IN DEVELOPING FETAL ADRENAL GLAND Some S-100 protein-positiv...

Ki-67 IN FETAL ADRENAL GLAND Figure 1-15 Ki-67 IN FETAL ADRENAL GLAND Immunoreactivity for Ki-67 is abundant in the definitive zone, which is the major site of cortical cell generation. Scattered individual stained cortical cells are also present in the provisional zone, along with aggregates More about this image found in Ki-67 IN FETAL ADRENAL GLAND Immunoreactivity for Ki-67 is abundant in the...

DORSAL ASPECT OF FETAL ADRENAL GLANDS Figure 1-17 DORSAL ASPECT OF FETAL ADRENAL GLANDS The dorsal surface of both adrenal glands from a 35-week premature infant shows a ridge (or crista) and a relatively smooth cortical surface. Each gland weighed 3 g. More about this image found in DORSAL ASPECT OF FETAL ADRENAL GLANDS The dorsal surface of both adrenal g...

ADRENAL GLAND FROM A 35-WEEK PREMATURE INFANT Figure 1-18 ADRENAL GLAND FROM A 35-WEEK PREMATURE INFANT In this transverse section, much of the fetal or provisional cortex has a dark appearance. This may be a normal feature and should not be confused with adrenal hemorrhage. More about this image found in ADRENAL GLAND FROM A 35-WEEK PREMATURE INFANT In this transverse section, ...

BECKWITH-WIEDEMANN SYNDROME Figure 2-19 BECKWITH-WIEDEMANN SYNDROME Chromaffin cells forming a nodule protruding from the fetal cortex are inappropriately mature for this stage of development and have clear cytoplasm. There is a morphologic resemblance of the nodule to normal extra-adrenal More about this image found in BECKWITH-WIEDEMANN SYNDROME Chromaffin cells forming a nodule protruding f...
