Patient's question:
JJ, there are some yellowish small granules in my foreskin, and I can see that they are covered with a layer of skin. What should I do in this situation?Doctor's answer:
It is smegma. Under the skin at the junction of the inner foreskin and the glans penis, there are certain sebaceous glands that continuously secrete a pale yellow oily substance. This substance mixes with shed skin debris and urine to form smegma.Hazards:
1. Directly irritates the glans penis, potentially leading to penile cancer.
2. Causes frequent inflammation of the foreskin and glans penis. Long-term inflammation can lead to the degeneration and worsening of local tissue cells in the penis.
3. Creates a poor environment for the glans penis, which may result in many precancerous conditions of the penis, such as penile horns, penile papillomas, genital warts, penile leukoplakia, and proliferative penile erythema. Such inflammation is prone to transforming into penile cancer.
