From the Guidelines
The next step in evaluating and managing penile bumps in a 30-year-old male with negative STI test results is to perform a thorough dermatologic examination and consider a biopsy of the lesions if there is suspicion of neoplastic change or if the disease fails to respond to adequate treatment. According to the British Association of Dermatologists guidelines for the management of lichen sclerosus, 2018 1, a biopsy must always be considered in patients with suspicion of neoplastic change, persistent area of hyperkeratosis, erosion or erythema, or new warty or papular lesions.
Key Considerations
- A dermatology referral is recommended to properly identify the nature of these bumps, as they could represent several benign conditions such as pearly penile papules, fordyce spots, or angiokeratomas.
- If the bumps are causing significant concern or discomfort, treatment options may include cryotherapy, laser therapy, or electrodesiccation depending on the specific diagnosis.
- For pearly penile papules, which are normal anatomical variants, reassurance may be all that's needed.
- For sebaceous hyperplasia or fordyce spots, topical retinoids like tretinoin 0.025% cream applied nightly for 6-12 weeks might help reduce their appearance.
Ruling Out Concerning Conditions
- The dermatologic evaluation helps rule out more concerning conditions like condyloma acuminata (genital warts) or molluscum contagiosum, which may require specific treatments despite negative standard STI panels.
- It's essential to note that many penile bumps are benign and require no treatment beyond reassurance, as stated in the guidelines for managing lichen sclerosus 1.

From the Research
Evaluation and Management of Penile Bumps
The patient, a 30-year-old male, presents with two small bumps on his penis and has tested negative for common sexually transmitted infections (STIs) such as gonorrhea, chlamydia, and syphilis, as well as HIV 2, 3, 4, 5, 6. Given the negative STI test results, the next step in evaluating and managing these penile bumps would involve considering other potential causes.
Potential Causes and Diagnostic Approaches
- Molluscum Contagiosum: This is a viral infection that can cause small, flesh-colored bumps on the skin, including the genital area. It is often asymptomatic and can be diagnosed through clinical examination or biopsy 2, 3.
- Other Dermatological Conditions: Various skin conditions, such as warts, herpes simplex, or other viral infections, could also present with similar symptoms. A thorough medical history, physical examination, and possibly further diagnostic tests (like dermoscopy or histopathology) may be necessary to determine the cause 2, 3.
Treatment Considerations
- Molluscum Contagiosum Treatment: If diagnosed with molluscum contagiosum, treatment options might include topical imiquimod, which has been shown to be effective and safe in some cases, particularly in children 3. However, the choice of treatment depends on the patient's specific situation and the severity of the condition.
- Importance of Accurate Diagnosis: It is crucial to accurately diagnose the cause of the penile bumps to provide appropriate treatment and prevent potential complications or transmission to others, if the condition is infectious.
Public Health and Prevention
- Screening for STIs: Regular screening for STIs is important, especially for individuals at higher risk, to prevent the spread of infections and to treat them early 4, 5, 6.
- Education and Awareness: Educating patients about safe sexual practices and the importance of regular STI screening can help in the prevention and control of STIs.
