Introduction – Encyclopedia of Nail Abnormalities

Our nails serve not only as a canvas for creativity and self-expression but also as indicators of our overall health. Nail abnormalities can present in various forms, colors, and patterns, often signifying underlying conditions or deficiencies. In this visual encyclopedia, we will delve into the world of nail abnormalities, exploring their causes, symptoms, and real-life examples. By understanding these conditions, you can identify potential concerns and seek appropriate care to maintain both the aesthetics and health of your nails.

Understanding Nail Abnormalities


  • Yellow Nails: Often associated with fungal infections, yellow nails can also indicate respiratory conditions or even psoriasis.
  • White Spots: These small, white spots or dots can result from minor injuries, nutrient deficiencies, or certain allergies.
  • Blue Nails: Blue nails can be a sign of poor circulation, lack of oxygen, or underlying medical conditions like Raynaud’s disease.
  • Dark Lines: Dark lines or stripes on the nails may indicate melanoma or other forms of skin cancer, requiring immediate medical attention.

2.Texture and Surface Irregularities:

  • Ridges: Vertical ridges are a common occurrence with age, but deep horizontal ridges can indicate nutritional deficiencies, trauma, or illness.
  • Pitting: Small depressions or pits on the nail surface may be associated with psoriasis, eczema, or autoimmune conditions.
  • Beau’s Lines: These transverse depressions across the nail plate can appear after severe illness, indicating a pause in nail growth.

3.Shape and Structure Abnormalities:

  • Clubbing: Enlargement of fingertips and a curved nail bed can be a sign of respiratory or cardiovascular diseases.
  • Spoon Nails: Also known as koilonychia, spoon-shaped nails can signify iron deficiency anemia or hemochromatosis.
  • Splitting and Brittle Nails: Dryness, frequent exposure to water, and certain medical conditions can lead to brittle, splitting nails.

4. Spoon Nails 

  • Iron Deficiency: One of the most common causes of spoon nails is iron deficiency anemia. A lack of sufficient iron in the body can lead to changes in the nail structure.
  • Hemochromatosis: This is a genetic condition where the body absorbs too much iron from food, leading to iron overload. It can result in various health issues, including spoon nails.
  • Trauma: Repeated trauma to the nail matrix, such as from excessive use of nail tools, can cause the nails to change shape over time.

5. Nail Pitting 

  • Psoriasis: Nail pitting is a common feature of psoriasis, an autoimmune skin condition that causes red, scaly patches on the skin. It can also affect the nails, leading to various changes, including pitting.
  • Alopecia Areata: This autoimmune condition primarily affects hair follicles, leading to hair loss. However, it can also result in nail changes, including pitting.
  • Eczema: Eczema, also known as atopic dermatitis, can cause inflammation and changes in the nails, including pitting.

6. Psoriasis

  • Pitting: One of the common nail changes seen in psoriasis is nail pitting. Pitting refers to the presence of small, shallow depressions or indentations on the nail’s surface. These pits can vary in number and size and are often seen on multiple nails.
  • Onycholysis: Onycholysis is the separation of the nail plate from the underlying nail bed. In psoriasis, this can cause the nails to become loose and eventually detach from the nail bed.
  • Oil Spots: Small, reddish-brown spots that resemble drops of oil under the nail plate are known as oil spots. They are a characteristic feature of psoriatic nail dystrophy.
