In a partial proximal avulsion, the proximal nail fold is reflected, so it's a better option when the proximal nail matrix
needs evaluation, she said.
Anti-cancer drugs usually affect rapidly growing cells and hence, the skin, hair follicles and nail matrix
are the frequent targets of their toxicities.
Infections, systemic diseases, and trauma cause onychomadesis by leading to discontinuance of growth of the nail matrix
, nail deformations, and horizontal lines on the nail (Beau's lines) (1).
The histopathological features seen with psoriatic nails were hypergranulosis of nail bed and neutrophilic infiltrate in nail matrix
Onychomadesis is the proximal separation of the nail plate from the nail matrix
Proximal Nail Fold was reflected back to allow full visualization of the nail matrix
3-7 In this rare case we removed the bridging granulation tissue up to the lateral nail matrix
and left for secondary healing.
Consequently, the mtNAPSI was used to measure the severity of psoriasis in the nail matrix
and nail bed for the most severely affected nail.
Realistically, patients who have had long-standing infections or chronic onychomycosis are likely to have sustained damage to the nail matrix
or subungual area so that, despite the clearance of infectious organisms, new nail growth may be permanently discolored and/or dystrophic, and some onycholysis (lifting of the nail plate) may persist.
Some onychomycosis infections, especially those involving the nail matrix
, may produce permanent scarring of the matrix, and, thus, the nail may never appear normal even after the infection is completely eradicated (Figure 1).
Cytotoxic agents and infections can induce the temporary arrest of proliferation of the nail matrix
, which is called Mees' lines of the nail plate.
Longitudinal erythronychia, as seen in our patient, results when the glomus tumor exerts pressure on the distal nail matrix
She said that with age the nail matrix
becomes atrophied in areas resulting in longitudinal ridging of nails.
Cuticles protect the nail matrix
, and so they should not be cut or trimmed but instead pushed back with a wooden spatula.
Outbreak of nail matrix
