ECTODERMAL—NEOPLASMS NOS
SALIVARY GLAND TUMORS ARE ALL ECTODERMAL
ADNEXAL TUMORS
SEBACEOUS GLAND=MOST COMMON
—-OF THE MEIBOMIAN GLAND—USUALLY PRESENT AS ULCERATED NODULAR LESOIN OF THE PALPEBRAE
SWEAT GLAND
APOCRINE OR ECCRINE GLAND CA
HAIR FOLLICLES
TRICHOLEMMAL CA OR MALIGNANT TRICHOLFOLLICULOMA
PILOMATRIXOMA—”OF MALHERBE”
NEUROECTODERMAL—NEURAL CREST CELL TUMORS
NOTOCHORD= STRUCTURAL VESTIGE FORMED FROM MESODERM–CLIVAL OR SACRAL CHORDOMA
EVENTUALLY BECOMES THE NUCLEUS PALPOSUS—VERTEBLRAL COLUM FORMS AROUND IT
STIMULATES NEURULATION PROCESS IN THE OVERLYING NEUROECTODERM
NEURULATION—-SOME OF THE NEUROECTODERM SEPERATES AN MIGRATES OUT TO FORM PERIPHERAL NEURAL STRUCTURES:
AFFERENT–DORSAL ROOT GANGLION
AUTONOMIC GANGLION—-SYMPATHETIC TRUNK, CN 3, 7, 9, AND 10 (GLOMUS CELL TUMORS—PARAGANGLIOMAS)
ADRENAL MEDULLA (CHROMAFFIN CELLS)—PHEOCHROMOCYTOMA, CHROMAFFINOMA
CELIAC,RENAL, INTESTINAL PLEXUS
