What is a keratoma?

A keratoma is indeed an acquired thickened patch of epidermis. This condition typically arises from excessive proliferation of keratinocytes in response to various external factors, such as friction or pressure. The result is a localized area of thickened skin, characterized by a prominent layer of keratin. Keratomas are often seen on areas of the body that undergo frequent rubbing or added stress, such as the palms and soles.

Understanding keratomas is important for differentiating them from various skin conditions and recognizing their benign nature. They are not inflammatory skin conditions, as they do not primarily involve immune response or irritation. Additionally, they do not stem from genetic skin disorders, nor are they classified as viral infections, which involve pathogens causing illness or inflammatory responses. Recognizing the characteristics of keratoma can help in assessing skin health and deciding on appropriate treatments if necessary.
