Abstract:
A fatal case of malignant atrophic papulosis (Degos disease) with optic nerve and spinal cord involvement is described. Magnetic resonance imaging (MRI) of the optic nerve showed abnormal signal enhancement on fat suppressed T1 weighted images after intravenous meglumine gadopentetate infusion. On T2 weighted sagittal images, a sawtooth pattern was observed over seven vertebral segments of the spinal cord. On necropsy, a severe loss of myelinated nerve fibres in the left optic nerve was seen, with thrombotic obstruction of the central retinal artery. Spongy degeneration was observed in all levels of the spinal cord, with patchy and motheaten patterns caused by thromboses and endothelial proliferation in subarachnoid vessels. Findings on MRI were consistent with findings on pathological examination.
Insights
Malignant atrophic papulosis (Degos disease) can fatally affect the optic nerve and spinal cord. MRI and necropsy revealed vascular thromboses and nerve damage, confirming the disease
Area of Science:
- Neurology
- Pathology
- Radiology
Background:
- Malignant atrophic papulosis, also known as Degos disease, is a rare and often fatal systemic vasculopathy.
- Previous literature primarily describes cutaneous and gastrointestinal manifestations.
Observation:
- This report details a fatal case of Degos disease with significant central nervous system involvement.
- Magnetic resonance imaging (MRI) demonstrated characteristic findings in both the optic nerve and spinal cord.
Findings:
- Optic nerve MRI revealed abnormal signal enhancement, consistent with inflammation or ischemia.
- Spinal cord MRI showed a unique 'sawtooth' pattern on T2-weighted images, indicative of vascular compromise.
- Necropsy confirmed severe demyelination in the optic nerve with central retinal artery thrombosis.
- Spinal cord pathology exhibited spongy degeneration attributed to thromboses and endothelial proliferation in subarachnoid vessels.
Implications:
- This case highlights the potential for extensive neurological involvement in Degos disease.
- Advanced neuroimaging, particularly MRI, can aid in diagnosing and characterizing CNS manifestations.
- Correlation between MRI findings and pathological examination validates the imaging techniques for Degos disease.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
