A circle of white flesh under the glans

A circle of white fleshy particles under the glans may be pearly penile papules, or it may be caused by diseases such as genital warts or ectopic sebaceous glands.

Pearly penile papules are a common benign lesion. They usually appear as a circle of small white or light red papules in the coronal sulcus of the glans penis. They are neatly arranged, uniform in size, and have a smooth surface. Pearly penile papules generally cause no symptoms, are not contagious, and usually do not require special treatment. If the patient experiences discomfort or aesthetic problems, laser treatment or cryotherapy may be considered.

Genital warts are a sexually transmitted disease caused by human papillomavirus infection. They appear as white or pink cauliflower-like growths on the glans, coronal sulcus, etc., with a rough surface and soft texture. Genital warts are contagious and require prompt medical treatment. Treatment methods include medication, laser therapy, cryotherapy, etc.

Ectopia sebaceum is caused by abnormal development of sebaceous glands. It is characterized by the appearance of small white or light yellow papules on the glans, coronal sulcus, etc., with a smooth surface and soft texture. Ectopia sebaceum generally does not cause uncomfortable symptoms, is not contagious, and usually does not require special treatment.

Patients are advised to keep the area clean and hygienic and avoid excessive washing or use of harsh lotions. If symptoms of discomfort occur or skin lesions change, you should seek medical examination promptly and follow the doctor's instructions for treatment after a clear diagnosis.
