What is the recommended treatment for a solitary bump on the scrotum that appeared during epididymo-orchitis?

From the Guidelines

For a solitary bump on the scrotum that appeared during epididymo-orchitis, the recommended treatment is to complete the full course of antibiotics prescribed for the underlying infection, typically a single antibiotic or a combination of two antibiotics active against Chlamydia trachomatis and Enterobacterales, as outlined in the European Association of Urology guidelines 1. The bump is likely an inflammatory nodule or small abscess related to the infection. While continuing antibiotics, apply warm compresses to the area for 15-20 minutes, 3-4 times daily to improve blood circulation and promote healing. Over-the-counter pain relievers like ibuprofen (400-600mg every 6-8 hours) can help manage discomfort and reduce inflammation. Scrotal support with snug underwear or a scrotal support bandage will minimize pain from movement. Some key points to consider in the diagnosis and treatment of epididymitis include:

• Clinical assessment to determine the presence of acute scrotal pain and swelling, and to rule out testicular torsion, a surgical emergency 1.
• The use of scrotal ultrasound examination to evaluate the epididymis and testicles, and to guide treatment decisions 1.
• The importance of completing the full course of antibiotics to ensure resolution of the infection and to prevent complications, such as abscess formation or testicular infarction. Most solitary bumps resolve with the treatment of the underlying epididymo-orchitis. However, if the bump persists after completing antibiotics, increases in size, becomes more painful, or if you develop fever or worsening symptoms, prompt medical reevaluation is necessary as surgical drainage might be required for an abscess. These recommendations work because antibiotics target the bacterial cause while supportive measures reduce inflammation and promote healing of affected tissues. It is also important to note that the treatment of epididymitis may involve the use of parenteral therapy, such as ceftriaxone 1000 mg i.m. or i.v., in cases of severe infection 1. In addition, the diagnosis and treatment of epididymitis should be guided by the results of diagnostic tests, such as midstream urine for culture, urethral swab/smear, and first voided urine for nucleic acid amplification test (NAAT) 1.

From the FDA Drug Label

Acute epididymo-orchitis caused by N. gonorrhoeae: 100 mg, by mouth, twice a day for at least 10 days. Acute epididymo-orchitis caused by C. trachomatis: 100 mg, by mouth, twice a day for at least 10 days

The recommended treatment for a solitary bump on the scrotum that appeared during epididymo-orchitis is doxycycline 100 mg, by mouth, twice a day for at least 10 days 2.

• The treatment should be continued for the full recommended duration, even if symptoms improve before completion.
• It is essential to note that the solitary bump on the scrotum may be a symptom of a more severe infection, and medical evaluation is necessary to determine the underlying cause and appropriate treatment.

From the Research

Treatment for Solitary Bump on Scrotum during Epididymo-orchitis

• The recommended treatment for a solitary bump on the scrotum that appeared during epididymo-orchitis depends on the underlying cause of the epididymo-orchitis 3, 4, 5.
• If the epididymo-orchitis is caused by Chlamydia trachomatis or Neisseria gonorrhoeae, the treatment of choice is a single intramuscular dose of ceftriaxone with 10 days of oral doxycycline 4, 5, 6.
• If the epididymo-orchitis is caused by enteric organisms, the treatment of choice is levofloxacin or ofloxacin alone 3, 5.
• However, if the solitary bump on the scrotum is a solitary fibrous tumor (SFT), the treatment is surgical resection of the tumor 7.
• It is essential to note that the diagnosis of the underlying cause of the epididymo-orchitis and the solitary bump on the scrotum is crucial in determining the appropriate treatment.

Diagnosis of Underlying Cause

• The diagnosis of the underlying cause of the epididymo-orchitis and the solitary bump on the scrotum can be made through a combination of physical examination, laboratory tests, and imaging studies 4, 5.
• Laboratory tests such as urethral Gram stain, urinalysis, and culture, as well as polymerase chain reaction assay for C. trachomatis and N. gonorrhoeae, can help guide therapy 4.
• Imaging studies such as ultrasound can help identify the presence of a solitary fibrous tumor (SFT) 7.

Importance of Accurate Diagnosis

• Accurate diagnosis of the underlying cause of the epididymo-orchitis and the solitary bump on the scrotum is essential in determining the appropriate treatment and preventing complications such as infertility and chronic scrotal pain 5.
• Delayed or inappropriate treatment can lead to poor outcomes, highlighting the need for prompt and accurate diagnosis 3, 4, 5.
