Term
the distal phalanx of each finger is rounded and bulbous. The nail plate is more convexed; and the angle between the plate and the proximal nail fold increases to 180 degress or more.
the proximal nail fold feels spongy or floating. |

Definition
clubbing of the fingers
(causes include--chronic hypoxia from heart disease or lung cancer and hepatic cirrhosis). |
|
|
Term
an inflammation of the proximal and lateral nail folds; maybe acute or chronic; folds are red, swollen, and often tender. the cutical maynot be visible.
people who frequently immerse thier nails in water are susceptible. Multiple nails are often affected. |

| white spots (leukonychia) |
|
|
Term
| these are transverse lines, not spots, and their curves are similiar to those of the lunula, not the cuticale. these uncommon lines may follow an acute or severe illness. they emergefrom under the proximal nail folds and grow out with the nails. |
|
Definition
| transverse white lines (mees' lines). |
|
|
Term
| small pits in the nails maybe early signs of this condition but are not specific for it. additional findings, not shown here, include oncholysis and a circumscribed yellowish tan discoloration known as an oil spot lesion. Marked thickening the the nails may develop. |

Definition
|

Term
| transverse depresssions in the nails associated with acute severe illness. The lines emerge fromunder the proximal nail folds weeks later and grow gradually out with the nails. As with Mees' lines, clinicacians may be able to estimate the timing of a causal illness. |
