Disorders Of The Nails

Examining the nails is an important part of physical examination and certain features may point to the underlying medical disorder. In some cases the nails may have local disease causing a disorder or abnormal findings.
Here we try to give a brief description of some of the nail disorders along with pictures for a better understanding.

1. Absent part: also known as Anonychia . It may be congenital or secondary to severe infection or allergic reaction. It is also seen in self inflicted trauma or in people who have a habit of nail biting.

Partial Anonychia 

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 Congenital Anonychia 

2. Nail Pitting: characterized by depressions on the surface of the nail is seen in conditions like psoriasis and connective tissue disorders like alopecia aerata and sarcoidosis. Nail pitting in one or two finger nails may be due to local trauma.

                                                Nail Pitting.

3, Clubbing Of the Nails: swelling of the terminal phalanges of the fingers and toes, giving them a “club” appearance; the normal 160° angle between the nail bed and the digit increases to 180°

Causes include:

Lung disease:
  • Lung cancer, mainly non-small-cell
  • Interstitial lung disease most commonly fibrosing alveolitis
  • Complicated tuberculosis
  • Lung absces
  • Bronchiectasis
  • Cystic fibrosis
Heart disease:
  • Congenital cynotic heart disease(most common cardiac cause)
  • Subacute bacterial endocarditis
Gastrointestinal and hepatobiliary:
  • Malabsorption
  • Inflammmatory bowel disease (Crohn's disease and ulcerative colitis)                                                           
  • Primary biliary cirrhosis                                                
Others:                                                                                                Nail clubbing
  • Graves disease (autoimmune hyperthyroidism) 
  • Familial and racial clubbing and "pseudoclubbing" (people of African descent often have what appears to be clubbing)
4. Spoon shaped nails: known as koilonychia and seen in iron deficiency anemia. 

5. Nail PigmentationLongitudinal melanonychia is a pigmented band that runs fro the proximal nail fold to the nail tip. The band, which can be tan, brown, or black, is caused by an increase in melanin pigment in the nail plate.

6. Splinter Hemorrhages: seen in bacterial endocarditis. 
                                                  Splinter Hemorrhages

7. Brittle nails: Brittleness of the nails, meaning that the nails easily become cracked, chipped, split, or peeled, can be observed as a sign of aging or in response to the long-term use of nail polish or exposure to moist conditions (including frequent swimming or dishwashing). Some diseases are also associated with changes in the nails, which can include brittleness. Thin and brittle nails can be a sign of hypothyroidism.

  1. Nice blog
    Have been totally convinced that HIV,and many others dangerous diseases can be best cured using the Herbal Medicine. Dr.Akpu the great and powerful herbalist cured me with his Herbal remedy. I'm Linda,15 years from Texas. I was born with HIV. I lost parents at my teenager age when I was 4th. I had to grew up with my mum only Sister, whom I loved so much. She was so worried about my life as my condition was her mature problem in life. I had taken lots of antiviral treatment to get ride of the virus not believing what there said HIV has no cure. I was on the internet when i came across blogs of testimony about a lady who where cured of a 7 years diagnose of Herpes by this powerful Herbalist, Dr.Akpu.I wrote down his mail @
    I told my Aunt,luckily it was the same Dr,we where referred to few months back by my pastor in church whom members have being testifying about of his cure We did contacted him and explained my problem to him.He prepared the medicine and sent to me with details of how to use and apply. After a while, I began to feel more strong than never before, I felt so lucky and happy when my Doctor congratulated me that he could found no HIV virus again in me. I knew I was free cos my body was so strong. His herbal medicine should have saved my parents life, i said!
