Symptoms of paraganglionic hyperplasia are mainly symmetrical growths on both sides of the penile girdle in men, and patients usually have no conscious symptoms. The paracolic gland is an anatomical structure located on the left and right sides of the ligament, usually the left and right are unequal in size and asymmetrical. However, when the paracolic glands of the tethered cord are stimulated, such as by a long foreskin or frequent masturbation, hyperplasia may occur when the structures on both sides are enlarged and tend to be symmetrical. Usually patients do not have abnormal self-conscious symptoms appearing and there is no obvious discomfort, so there is usually no need for special treatment. When the patient has symptoms such as itching and swelling, an infection may have occurred and antibacterial and anti-inflammatory treatments are needed. It also usually needs to be differentiated from diseases such as condyloma acuminatum. It is recommended that when patients find an unknown swelling in the penis, they should consult a doctor in time for a clear examination and standardized treatment under the guidance of the doctor.
