PHEOCHROMOCYTOMA: NEUROENDOCRINE MARKERS Figure 8-37 PHEOCHROMOCYTOMA: NEUROENDOCRINE MARKERS The tumor cells express nuclear INSM1 (A), cytoplasmic synaptophysin (B), and cytoplasmic chromogranin A (C). These biomarkers indicate that this is a neuroendocrine neoplasm but are not specific for phe...

PHEOCHROMOCYTOMA Figure 8-22 PHEOCHROMOCYTOMA The tumor cells are round and regular, with abundant cytoplasm, resembling cells of an epithelial neuroendocrine tumor. More about this image found in PHEOCHROMOCYTOMA The tumor cells are round and regular, with abundant cyto...

ECTOPIC ACTH SYNDROME Figure 3-11 ECTOPIC ACTH SYNDROME Diffuse ACTH-dependent adrenocortical hyperplasia from an adrenal metastasis of an ACTH-secreting lung neuroendocrine tumor. More about this image found in ECTOPIC ACTH SYNDROME Diffuse ACTH-dependent adrenocortical hyperplasia fr...

PHEOCHROMOCYTOMA IN A PATIENT WITH MEN1 Figure 10-7 PHEOCHROMOCYTOMA IN A PATIENT WITH MEN1 This adrenal pheochromocytoma was identified at the time of surgery for a pancreatic neuroendocrine tumor in a patient with a history of multi-glandular parathyroid disease. While the tumor has no specific... More about this image found in PHEOCHROMOCYTOMA IN A PATIENT WITH MEN1 This adrenal pheochromocytoma was ...

ECTOPIC ACTH SYNDROME Figure 3-6 ECTOPIC ACTH SYNDROME Transverse sections of adrenal glands surgically resected from a patient with ectopic ACTH syndrome due to a bronchial neuroendocrine tumor. The tumor had remained occult for several years. The right adrenal gland weighed 12 g and the left 11...

NORMAL PERITHYROIDAL PARAGANGLION Figure 9-10 NORMAL PERITHYROIDAL PARAGANGLION A: This paraganglion, discovered incidentally in peri-thyroidal soft tissue in an adult patient with a multinodular goiter, is architecturally similar to the carotid body in figure 9-7 . The intimate association of n... More about this image found in NORMAL PERITHYROIDAL PARAGANGLION A: This paraganglion, discovered inciden...

NORMAL ABDOMINAL PARAGANGLION Figure 9-5 NORMAL ABDOMINAL PARAGANGLION A: Low magnification shows proximity of this paraganglion to adjacent developing ganglia, adrenal gland, and kidney in a mid-second trimester fetus. B: Higher magnification of paraganglion in a mid-second trimester fetus. Thi... More about this image found in NORMAL ABDOMINAL PARAGANGLION A: Low magnification shows proximity of this...

MESENTERIC PARAGANGLIOMA Figure 9-14 MESENTERIC PARAGANGLIOMA A: This paraganglioma composed of basophilic and clear cells was incidentally discovered in an asymptomatic patient with no other tumors. Fat invasion, poorly defined irregular cell nests, and diffuse growth are putative risk factors f...
