A dilated pore is a type of skin lesion that appears as an enlarged opening on the skin, often resembling a large blackhead. It is a benign condition and is commonly found on the face, neck, and back. The dilated pore is essentially a large, open comedo that can become filled with keratin and sebum.

Pathophysiology

The formation of a dilated pore is primarily due to the accumulation of keratin and sebum within a hair follicle. Over time, the follicle becomes distended, leading to the characteristic appearance of a large, open pore. Factors such as genetics, hormonal changes, and aging can contribute to the development of dilated pores.

Clinical Presentation

Patients with dilated pores typically present with a single, large, open pore that may be filled with a dark plug of keratin and sebum. The surrounding skin may appear normal or slightly raised. Dilated pores are usually asymptomatic but can become inflamed or infected if not properly managed.

Diagnosis

Diagnosis of a dilated pore is primarily clinical, based on the characteristic appearance of the lesion. A dermatologist may use a dermatoscope to examine the pore more closely. In some cases, a biopsy may be performed to rule out other conditions such as basal cell carcinoma or squamous cell carcinoma.

Treatment

Treatment of dilated pores is often not necessary unless the patient desires removal for cosmetic reasons. Options for treatment include:

• Extraction of the keratin plug using a comedone extractor.
• Laser therapy to reduce the size of the pore.
• Chemical peels to improve skin texture and reduce pore size.
• Topical retinoids to promote cell turnover and prevent clogging of the pore.

Prevention

Preventive measures for dilated pores include maintaining a regular skincare routine that includes:

• Gentle cleansing to remove excess oil and debris.
• Use of non-comedogenic products to avoid clogging pores.
• Regular exfoliation to remove dead skin cells.
• Protection from sun exposure to prevent skin damage.
