👉 A keratosic lesion is a type of cancer that occurs in the眼角膜, which is a clear, transparent part of the eye. Keratoses are caused by abnormal growths called keratinocytes, which are cells that make up the outer layer of the skin and are responsible for the appearance of wrinkles and creases on the face. Keratoses can be either benign or malignant depending on whether they grow rapidly or slowly in the body over time.
