Boulder The small bump under the left testicle may be caused by varicocele, epididymal cyst, epidermoid cyst, hernia or testicular tumor. Common accompanying symptoms include local swelling and pain, tenderness or falling sensation. It is recommended to seek medical treatment in time for a clear diagnosis.
1. Varicocele
Varicocele is more common in young adults and results in the appearance of earthworm-like masses in the scrotum due to poor venous return. It may be related to factors such as standing for a long time and increased intra-abdominal pressure. The typical manifestation is a swollen feeling in the scrotum, which is aggravated after exercise. For mild cases, you need to avoid standing and sitting for long periods of time. For moderate to severe cases, you can follow the doctor's advice and use medications such as Maizhiling tablets and diosmin tablets, or consider high spermatic vein ligation.
2. Epididymal cyst
Epididymal cysts are common, benign, cystic lesions of the head of the epididymis that are usually painless and may be related to local ductal obstruction. A smooth round mass can be palpated and confirmed by ultrasonography. Those smaller than 1 cm and asymptomatic do not need treatment. Larger cysts can be treated by epididymal cyst resection when symptoms of compression occur.
3. Epidermoid cyst
Epidermoid cysts in the scrotal skin are dermatological lesions that are formed by abnormal proliferation of epidermal cells. It manifests as pushable subcutaneous induration, which may cause redness, swelling and pain secondary to infection. After diagnosis, cyst removal can be performed under local anesthesia. The wound must be kept clean and dry after surgery.
4. Inguinal hernia
When an inguinal hernia occurs, the intestine may pass through a weak area and enter the scrotum to form a mass. Typical symptoms include protrusion of the mass when standing and retraction when lying down, accompanied by a pulling sensation. Infants and young children can try conservative treatment with hernia belts, while adults need radical surgery such as preperitoneal space hernia repair.
5. Testicular tumors
Testicular tumors often appear as painless solid nodules, which are hard in texture and grow rapidly. It may be related to cryptorchidism, genetics and other factors, and needs to be confirmed through tumor marker testing and imaging examinations. Comprehensive treatments such as radical orchiectomy combined with radiotherapy and chemotherapy are selected according to the pathological type.
In daily life, you should avoid wearing tight pants, reduce local compression behaviors such as riding a bicycle for a long time, and regularly self-examine testicular morphological changes. If you find that the mass continues to enlarge, becomes hard, or is accompanied by symptoms such as hematuria, you must immediately seek treatment at a urology department. Avoid applying heat or massaging yourself before diagnosis to avoid masking the condition or causing the tumor to spread.
