The image displays a prominent skin lesion, which appears as a raised nodule with a large, dark, open pore at its center. This type of blemish could be a dilated pore of Winer, which is essentially a giant blackhead, or a form of epidermoid cyst. Both are typically benign and result from a blocked hair follicle becoming impacted with a buildup of skin cells (keratin) and oil.
While visually concerning, attempting to extract or "pop" such a deep lesion at home is highly discouraged. This can push the contents deeper, leading to severe inflammation, infection, and a high risk of permanent scarring. For any large, persistent, or unusual skin growth, it is crucial to see a dermatologist for a proper diagnosis and to discuss safe, sterile treatment options.
