Pseudoleukonychia: white spots that form on the surface of the nail, caused by outside organisms like fungi
White spots on nails, also known as leukonychia, are usually harmless but may indicate a medical condition. There are a few main types of leukonychia, including apparent leukonychia and true leukonychia. Pseudoleukonychia is a type of leukonychia where white spots form on the surface of the nail. It is caused by outside organisms, such as fungi, and can appear as flaking on top of the nail. In some people, pseudoleukonychia appears as one or two medium-sized spots, while in others, the spots may be very large. You may have spots on only one nail, or you may have spots on many nails. White spots usually mean that your nails have experienced some sort of stress, such as an injury, an infection, or an allergic reaction. They can also be a side effect of certain medications.

Apparent leukonychia: white spots that appear on the nail bed and disappear when pressure is placed on the nail
White spots on nails, also known as leukonychia, are usually harmless but may indicate a medical condition. There are a few main types of leukonychia, including apparent leukonychia, which is when white spots appear on the nail bed and disappear when pressure is placed on the nail.
Apparent leukonychia is caused by stress to the nails. This could be from an injury, such as hitting your nail against a hard surface, an infection, or an allergic reaction. White spots can also be side effects of medications.
Apparent leukonychia is characterised by the appearance of white spots on the nail bed, which is the skin underneath the nail. These spots disappear when pressure is placed on the nail. This is different from true leukonychia, where the spots originate from the nail matrix (where the nail grows) and appear on the nail plate.
If you have apparent leukonychia, it is important to identify and address the underlying cause of the stress to your nails. This may involve treating an infection or allergy, or making changes to your medication.

True leukonychia: white spots that originate from the nail matrix and appear on the nail plate
White spots on nails, also known as leukonychia, are usually harmless but may indicate a medical condition. There are a few main types of leukonychia, including pseudoleukonychia and true leukonychia. Pseudoleukonychia is caused by outside organisms, such as fungi, and appears as flaking on top of the nail. True leukonychia, on the other hand, originates from the nail matrix, where your nail grows, and appears on the nail plate. This type of leukonychia is characterised by white spots that do not disappear when pressure is applied to the nail.
True leukonychia is typically the result of some sort of stress to the nails. This could be from an injury, such as hitting your nail against a hard surface, an infection, or an allergic reaction. In some cases, white spots may also be a side effect of certain medications. While leukonychia is generally harmless, it is always a good idea to consult a healthcare professional if you have any concerns or if the spots persist or worsen.
It is important to note that there are many myths and misconceptions surrounding white spots on nails. For example, some people believe that white spots indicate that you have recently told a lie or are about to receive a letter with money in it. However, these beliefs are not based on scientific evidence. While vitamin deficiencies can cause white spots on nails, it is important to consult a doctor or dermatologist to determine the exact cause and receive appropriate treatment.
If you notice white spots on your nails, it is generally recommended to see a dermatologist for a proper diagnosis and treatment plan. They may ask about your medical history, any medications you are taking, and any recent injuries or infections. Based on this information and a physical examination of your nails, they can determine the most likely cause and recommend appropriate treatment options. In some cases, additional tests may be necessary to rule out more serious underlying conditions.
