What is the diagnosis described for the cyst on the back in OPD7273?

A sebaceous (epidermoid) cyst is a common subcutaneous lesion that presents as a well-defined, usually mobile and non-tender swelling, often with a central punctum and keratinous material inside. This fits a cystic lump on the back best, because the back is a typical site for these cysts and the key feature is the cystic nature with keratin content rather than a solid, fatty, or pigmented lesion. Lipoma tends to feel soft, very mobile, and rubbery, without a central opening or keratin content. Dermatofibroma is usually a firm, small nodule that can be pigmented and may show a dimple sign when pressed. Seborrheic keratosis looks like a pigmented, waxy, stuck-on plaque, not a true cyst. Therefore, the description aligns most closely with a sebaceous cyst on the right upper back.
