👉 A callioma is a type of epithelial tumor in the skin that arises from a layer of keratinized cells, often associated with aging and inflammation. These tumors can be benign or malignant depending on their location within the skin, as well as any underlying conditions like diabetes or certain medications. They are typically seen in people over 40 years old who have experienced chronic inflammatory diseases such as rheumatoid arthritis, psoriatic arthritis, or multiple sclerosis.
