| necrotizing fasciitis | A rare soft-tissue infection primarily involving the superficial fascia and resulting in extensive undermining of surrounding tissues; progress is often fulminant and may involve all soft-tissue components, including the skin; usually occurs postoperatively, after minor trauma, or after inadequate care of abscesses or cutaneous ulcers. See: group A streptococcal necrotizing fasciitis. (05 Mar 2000) |

| necrotizing papillitis | <nephrology> Necrosis of renal papillae, occurring in acute pyelonephritis, especially in diabetics, or in analgesic nephropathy; renal failure may result. Synonym: necrotizing papillitis. (05 Mar 2000) |

| subacute necrotizing encephalomyelopathy | A rare fatal disorder, primarily of children, being both acute and chronic in onset, manifested primarily as brainstem dysfunction, with ataxia, cranial nerve palsies, pseudobulbar palsy, hemi-or quadriplegia, mental deterioration, and involuntary movements; deficiencies of pyruvate dehydrogenase or cytochrome C oxydase have been found in some patients; pathologically, there is widespread symmetric necrosis involving much of the brainstem; these changes are similar to those seen with Wernicke encephalopathy.

| subacute necrotizing myelitis | A disorder of the lower spinal cord in adult males resulting in progressive paraplegia. Synonym: angiodysgenetic myelomalacia, Foix-Alajouanine myelitis. (05 Mar 2000) |
| disseminated necrotizing leukoencephalopathy | <radiology> DNL: demyelination due to radiation and chemotherapy, decreased density in deep white matter, with or without peripheral, patchy enhancement, calcification: basal ganglia, grey/white junction (12 Dec 1998) |
| fasciitis, necrotizing | A fulminating group a streptococcal infection beginning with severe or extensive cellulitis that spreads to involve the superficial and deep fascia, producing thrombosis of the subcutaneous vessels and gangrene of the underlying tissues. A cutaneous lesion usually serves as a portal of entry for the infection, but sometimes no such lesion is found. (12 Dec 1998) |
