Patient's question:
My boyfriend said he has had small blisters on his coronal sulcus recently, but he didn't pay much attention. It seems like there are more of them lately. How should small blisters on the coronal sulcus be treated?Doctor's answer:
Based on your description, it is possible that this condition could be related to balanoposthitis. The causes are often due to phimosis, excessive foreskin, masturbation, trauma, and infection, among others. These factors lead to the shedding of keratinized epithelial cells and glandular secretion, creating a favorable environment for other bacteria to multiply and cause inflammation. The clinical manifestations typically include local itching, redness, swelling, erosion, and even ulcers, along with the presence of discharge and a bad odor. In severe cases, it may lead to fever, chills, systemic symptoms, or even penile swelling and pain. It is recommended to seek medical examination and treatment at a hospital.
