There may be various causes for the hardening of a strip on the epidermis of the penis, including superficial phlebitis, chronic obstructive lymphadenitis, and sclerodactyly, etc. It is recommended to go to the hospital for further examination.
1. Superficial phlebitis: under normal circumstances, there are superficial veins distributed under the epidermis of the penis, if there is an infection that leads to superficial phlebitis, it may lead to the penis being hardened by the superficial veins and so on.
2. Chronic obstructive lymphadenitis: If the invasion of bacteria is caused by local trauma, spread of inflammation due to infection of surrounding tissues, it may lead to obstruction and infection of lymphatic vessels and hardening of the penis.
3. Penile sclerosis: In addition, it cannot be ruled out that penile sclerosis occurs due to persistent inflammation, leukomalacia injury, etc., resulting in lumpy, striated hard nodules.
Therefore, it is recommended to go to the hospital for further examination under the guidance of the doctor to clarify the cause of the disease and timely treatment.
