The image shows a large, raised and swollen area across the upper back and shoulder, with numerous dark, crater-like openings resembling blackheads or enlarged pores. The unusual size and density make it difficult to identify from appearance alone, especially because similar images circulating online are sometimes digitally altered or artificially created.

One possibility is a severe form of comedonal or nodulocystic acne, in which pores and hair follicles become blocked and inflamed. Other possibilities can include unusual clusters of open comedones or other enlarged skin lesions, and conditions that produce prominent follicular lesions can also look similar in photos.

Because the appearance is so unusual, attempting to squeeze, puncture, or extract the openings at home could cause infection, bleeding, and permanent scarring. If something similar occurs on a real person’s skin, it should be examined by a dermatologist to determine the underlying cause before any treatment is attempted.

Depending on the diagnosis, treatment for severe acne or other follicular disorders may include prescription retinoids, antibiotics, or other systemic medications. A dermatologist may also recommend professional extraction or procedures such as chemical peels or laser treatment when appropriate, but getting an accurate diagnosis first is essential.
