Mass or Swelling Around the Anus
Masses or swelling around the anus can range from common, benign conditions like hemorrhoids to more serious issues requiring prompt treatment. These lumps may be internal or external, painful or painless, and can vary in size. While many causes are treatable, any new or changing mass should be evaluated by a healthcare provider to rule out serious conditions.
⚠️ Seek Emergency Care For:
- Severe pain with high fever
- Rapidly growing or enlarging mass
- Heavy rectal bleeding that won't stop
- Signs of infection (pus drainage, red streaks)
- Inability to have bowel movement with severe pain
- Severe swelling preventing sitting or walking
- Mass with unbearable pain
- Symptoms of sepsis (high fever, rapid heart rate, confusion)
Definition and Overview
An anal mass or swelling refers to any abnormal lump, bump, or enlarged area in or around the anus. These can develop from various structures including blood vessels (hemorrhoids), glands, skin tags, or deeper tissues. The location, consistency, and associated symptoms help determine the underlying cause.
While hemorrhoids are the most common cause of anal masses, it's important not to assume all anal lumps are hemorrhoids. Some masses may indicate infections, inflammatory conditions, or rarely, cancer. Early evaluation is crucial, especially for new or changing masses, as many conditions are more easily treated when caught early.
Common Causes
Common Benign Causes
- External hemorrhoids: Swollen veins
- Thrombosed hemorrhoids: Blood clot in hemorrhoid
- Anal skin tags: Excess skin folds
- Anal fissures: Tears with swelling
- Perianal hematoma: Blood collection
- Anal warts: HPV infection
Infectious Causes
- Perianal abscess: Infected gland
- Anal fistula: Tunnel from infection
- Pilonidal cyst: Hair follicle infection
- STIs: Herpes, syphilis, gonorrhea
- Fungal infections: Candida overgrowth
- Fournier's gangrene: Serious infection
Inflammatory Conditions
- Crohn's disease: Perianal involvement
- Hidradenitis suppurativa: Sweat gland disease
- Inflammatory bowel disease: Associated masses
- Bartholin gland cyst: In women
- Infected hair follicles: Folliculitis
- Contact dermatitis: Allergic reaction
Serious Conditions
- Anal cancer: Squamous cell most common
- Rectal prolapse: Tissue protrusion
- Anal melanoma: Rare but aggressive
- Lymphoma: Lymph node involvement
- Metastatic disease: From other cancers
- Sarcoma: Soft tissue tumor
Associated Symptoms
Anal masses often occur with other symptoms that help identify the cause:
- Rectal pain: Varies by cause
- Rectal bleeding: Bright red or dark
- Itching: Common with many conditions
- Discharge: Pus, mucus, or blood
- Changes in bowel habits: Constipation or diarrhea
- Straining: During bowel movements
- Feeling of incomplete evacuation: Blockage sensation
- Fever: Suggests infection
- Weight loss: With serious conditions

- HPV infection: Anal cancer risk
- HIV/AIDS: Increased cancer risk
- Smoking: Cancer risk factor
- Inflammatory bowel disease: Complications
- Previous anal cancer: Recurrence risk
Diagnostic Approach
Physical Examination

- Proctoscopy: Rectum examination
- Colonoscopy: If indicated
- MRI or CT: Complex cases
- Biopsy: Suspicious lesions
- STI testing: If warranted
