tumor. A: Mature GN was seen in much of the resected tumor when the patient was a little over 18 years of age during a debulking procedure. B: Other areas of the same tumor show transition to a malignant peripheral nerve sheath tumor.

GANGLIONEUROMA Figure 11-42 GANGLIONEUROMA A: This tumor contained a few small ganglia. A small myelinated nerve is present at one pole of a ganglion. The ganglion is probably incorporated secondarily in the tumor. B: A large bundle of myelinated nerve is present in this GN and is most likely More about this image found in GANGLIONEUROMA A: This tumor contained a few small ganglia. A small myelin...

pigmentation, and endocrine overactivity (Carney complex). There was a complex history of a retrogastric malignant melanotic nerve sheath tumor (formerly “melanotic schwannoma”), fibrolamellar hepatoma, hyperpigmentation of the inner canthus of both eyes, and most recently, an ovarian serous cystadenoma More about this image found in PRIMARY PIGMENTED NODULAR ADRENOCORTICAL DISEASE A large pigmented macrono...

CAROTID BODY PARAGANGLIOMA Figure 9-12 CAROTID BODY PARAGANGLIOMA The tumor is completely encapsulated and has protruding segments of nerve and artery (top left). The cut surface shows focal cystic degeneration and prominent cavernous blood vessels. A distinct large fleshy nodule is present More about this image found in CAROTID BODY PARAGANGLIOMA The tumor is completely encapsulated and has pr...

of neuroendocrine cells and nerve fibers is potentially mistaken for perineural infiltration by paraganglioma, medullary thyroid carcinoma, or other tumors. Paragangliomas arising from normal paraganglia in or near the thyroid gland are especially likely to be mistaken for medullary thyroid carcinoma.
