الثؤلول الأخمصي

Quick summary

A plantar wart is a growth on the sole caused by certain human papillomavirus types. It may hurt when walking and resemble a corn. Confirming the diagnosis matters before acids or freezing are used.

What is Plantar Wart?

Warts may disappear spontaneously but can persist for months or years. A foot wart does not imply sexually transmitted infection; skin-associated HPV types differ from those affecting mucosal surfaces.

Symptoms

A rough, thickened area may contain tiny dark dots representing small blood vessels. Weight can push the lesion inward and make it painful. Warts may cluster; pain or color alone does not confirm diagnosis.

Causes

The virus enters through vulnerable, moist or damaged skin and spreads through contact or contaminated surfaces. Picking can spread it locally. The delay before appearance makes the precise source difficult to identify.

Risk factors

Children, young people and people with reduced immunity are more susceptible. Repeated exposure to wet communal surfaces and minor skin damage facilitate infection, but having a wart is not proof of poor hygiene.

Diagnosis

Examination assesses the lesion and skin lines. An unusual, bleeding or treatment-resistant growth may require further investigation or biopsy. Do not cut into it to check its depth or identity.

Treatment

Observation is reasonable when it is not troublesome. Options include an appropriate salicylic-acid product or professionally guided freezing, often over repeated treatments. Avoid self-treatment with acids if you have diabetes, poor circulation or reduced sensation, and never cut out the wart.

Complications

Pain can alter walking, and additional lesions may spread. Treatment can cause irritation, blisters or scarring, and recurrence is possible. No method guarantees clearance in one session.

Prevention

Wear footwear in shared wet areas, keep feet dry and avoid sharing files or towels. Wash hands after touching the lesion and avoid picking. Do not use a wart file on healthy skin.

When to see a doctor

Seek review for pain, bleeding, change or failure to improve. Obtain advice before treatment if you have diabetes, immune suppression or circulation problems. Pus or increasing redness around a wound needs prompt assessment.
