Mosaic Warts: Symptoms, Causes & Treatments

Written by Dave

Mosaic warts are one particular type of plantar warts. The characteristic feature of the mosaic wart is its cluster-like formation. Mosaic warts closely resemble small lesions in their early stages. In the initial stages, mosaic warts look like small puncture marks, black in color.

As they develop, they acquire the look of a brown cauliflower, with dark spots in the middle.

Symptoms of Mosaic Warts

The following are some signs that you need to look out for in case you fear you have Mosaic warts.

  • People often ignore these warts as they appear on the feet. As a result of walking, these warts are pushed even deeper into the skin thus increasing the pain. At times it feels as if you are stepping on a stone every time you take action. This is the most prominent symptom of Mosaic Warts.
  • In the area where the Mosaic warts form, the skin turns brownish or grayish-yellow in color. The upper surface of the skin becomes smooth in the initial days.
  • You may also notice bleeding from warts when pressure is applied to them, and this happens when the blood clots or thrombosed capillaries rupture located deeper in the layers of the skin.
  • Often, Mosaic Warts appear in areas over bones or on points where it is exerted when walking. This makes it even more painful for the patients.

What Causes Mosaic Warts?

Mosaic warts occur on foot and are due to a strain of virus known as Human papilloma virus (HPV1). This virus enters into the body through cuts and bruises in the skin: the most vulnerable site is the foot which is often dry and cracked.

HPV1 virus can stay in wet areas for months without any host, walking barefooted in wet areas of the swimming pool, public showers, the locker room of gyms etc., all increase the risk of infection. Mosaic warts sometimes also occur on the fingers and hand.

Treatment Options for Mosaic Warts

Mosaic warts many times disappear on their own without any treatment, especially in children; however, in adults, they are more stubborn. There are several ways to remove them with prescribed and non-prescribed drugs. Other methods usually used include:

  • Cryotherapy (freezing with liquid nitrogen).
  • They can also be removed
  • Mosaic warts can also be treated by the application of salicylic acid which is the active ingredient in aspirin. Salicylic acid comes in different forms such as gels, liquids or even patches.
  • Mosaic warts can also be treated by covering warts with duct tape.
  • Mosaic warts can be treated, by getting rid of the dead or dying skin on the wart, which may help to heal faster, especially if you opt to forgo other treatments. You can make use of a pumice stone, emery board, or foot file to gently remove the layers of dead or dying skin from the wart.
  • Mosaic warts can as well be treated by grinding up to 4-5 Vitamin C tablets and making a paste to apply to warts and this fights the virus that causes

Receiving immune therapy can also help to heal warts, and this is done by injecting warts with antigens or creams.

How do Mosaic Warts Spread?

This wart is spread from person to person. The transmission can be indirect. For example, a child with a wart on his hand may touch a playground surface that is then touched by another child and by this, the wart can spread to others. It can also spread when the person with this mole uses a shower without wearing shower shoes and another person then uses it.
