Buschke Lowenstein Tumor

Overview

Buschke-Lowenstein tumor is a rare, wart-like growth that usually appears around the genitals or anus. It starts as a small bump and slowly grows into a large, cauliflower-shaped mass. It is caused by certain types of human papillomavirus (HPV), a common virus. Although it is not a typical cancer, it can behave aggressively and sometimes turns into cancer. It is treatable.

No, it is very rare. Most people have never heard of it. It makes up a tiny fraction of all HPV-related growths.

It most often affects adults, especially men, but it can affect anyone. People with weaker immune systems are at higher risk. It is uncommon in children.

Symptoms

Common symptoms

• a small, flesh-colored bump in the genital or anal area
• the bump slowly grows into a larger, cauliflower-like mass
• pain or discomfort
• bleeding or discharge from the growth
• a bad smell
• itching or irritation
• difficulty with urination or bowel movements if the growth is large

Symptoms in children

• similar growths but very rare
• any wart-like growth in a child should be checked by a doctor
• it may be linked to HPV passed during birth or through skin contact

Symptoms in older adults

• growth may grow more quickly due to changes in the immune system
• they may also have other health conditions that complicate care

Causes

Main causes

• infection with human papillomavirus (HPV), especially types 6 and 11
• long-term skin contact with an infected person
• a weak immune system that cannot clear the virus

Risk factors

• having multiple sexual partners
• unprotected sex
• smoking
• a history of other HPV-related conditions
• a weakened immune system (for example, from HIV or certain medicines)
• poor hygiene

When to see a doctor

See a doctor urgently if:

• you have a growth that is bleeding heavily
• you cannot pass urine or stool normally
• you have a growth that is very painful or rapidly changing

Book a routine appointment if:

• you notice any new or growing bump in the genital or anal area
• you have a wart-like growth that lasts for more than a few weeks
• you have a partner with HPV or genital warts

Diagnosis

A doctor will first ask about your symptoms and examine the growth. They may take a small sample (biopsy) to look at it under a microscope. This is the only way to confirm the diagnosis.

Tests that may be done

• physical examination of the growth
• biopsy (taking a small piece of tissue)
• HPV testing of the tissue sample
• imaging tests like MRI or CT scan if the growth is large

What to expect at your appointment

The exam is usually quick and painless. A biopsy may cause some discomfort. Results can take a few days to a week. Your doctor will explain what the results mean and discuss next steps.

Treatment

Treatment aims to remove the entire growth and prevent it from coming back. Your doctor will work with you to choose the best plan. Surgery is the most common and effective approach.

Self-care at home

• keep the area clean and dry
• avoid scratching or picking at the growth
• use condoms during sex to reduce spreading HPV
• do not smoke, as smoking can slow healing
• attend all follow-up visits

Medical treatments

Depending on the size and location, a specialist may use topical creams applied directly to the growth, or treatments that help your immune system fight the virus. Some treatments are used before or after surgery. Your doctor will discuss what is right for you. Remember, do not use any over-the-counter wart treatments on the genital area unless a doctor says it is safe.

When is surgery considered?

Surgery is often needed to remove the tumor completely. The type of surgery depends on where the tumor is and how large it is. In some cases, a specialist (such as a dermatologist or urologist) will perform the procedure.

Living with this condition

After treatment, you may have some discomfort and need time to heal. Follow your doctor's instructions about wound care. Keep the area clean and watch for signs of infection. It is normal to feel anxious about the condition, but many people recover fully.

Lifestyle tips

• stop smoking to improve healing and lower the risk of recurrence
• limit alcohol, which can affect the immune system
• practice safe sex to avoid passing HPV to others
• eat a balanced diet rich in fruits and vegetables to support your immune system

Diet and exercise

A healthy diet and regular gentle exercise can help your body recover and strengthen your immune system. Ask your healthcare provider about what level of exercise is safe for you during recovery.

Mental health and emotional wellbeing

A diagnosis of Buschke-Lowenstein tumor can be distressing. You may feel embarrassed, anxious, or worried about the future. These feelings are common. Talking to a counselor or a support group can help.

Prevention

You can lower your risk by practicing safe sex, getting the HPV vaccine, and not smoking. Because the virus is very common, there is no guaranteed way to prevent infection, but these steps help.

Vaccines

There are vaccines that protect against the types of HPV that cause most genital warts and many cancers. Talk to your doctor about whether vaccination is right for you. Even if you have already had HPV, the vaccine may protect against other types.

Screening programmes

There are no routine screening tests for Buschke-Lowenstein tumor. However, regular check-ups and asking your doctor to examine any unusual growth are important. If you have had the tumor, follow-up visits help catch any recurrence early.

Complications

If left untreated

• the tumor can grow very large
• it can invade nearby tissues, such as the bladder or rectum
• it can block the urinary or digestive tract
• it can change into a type of skin cancer (squamous cell carcinoma)
• it can cause severe pain, bleeding, or infection

Long-term outlook

With prompt and complete treatment, most people recover fully. The tumor can sometimes come back, so regular follow-up care is essential. Even if the tumor has turned into cancer, treatment is possible, and many people do very well. You are not alone—your healthcare team will support you.
