A keratoma refers to a thickened area of skin. This localized hypertrophy of the stratum corneum, the outermost layer of the epidermis, can present as a raised, often firm lesion. Common examples manifest as corns and calluses on the feet, resulting from repeated pressure or friction. Certain types can also appear on other areas of the body exposed to similar conditions.
Understanding the formation and characteristics of these skin alterations is important for differentiating them from other dermatological conditions. Proper identification facilitates appropriate management and preventative measures. Historically, addressing these hyperkeratotic lesions has been a concern, leading to the development of various treatments ranging from simple emollients to surgical interventions.
