What is a perianal hematoma?

A perianal hematoma is a small accumulation of blood around the anal area, which often appears as a dark or bluish protuberance. This condition generally occurs due to an injury or excessive pressure in the anal region, which can occur when lifting heavy objects or when straining when using the bathroom.

It is important to know perianal hematomas because many people can overlook the early signs, thinking that they are only minor discomforts. However, detecting these signs early can lead to faster help and better results.

Learning about this condition is very important. Knowing what a perianal hematoma is, what can cause it and what symptoms to look for can help people to obtain medical attention when necessary. Research shows that this problem is quite common, with different rates according to age and lifestyle. While it may not be a serious health problem for everyone, leaving it without treating can provoke complications such as infections or more pain.

Causes and risk factors

Cause/Risk factor	Details
Straining during bowel movements	Excessive pressure from constipation or prolonged straining can break the blood vessels around the anus.
Chronic constipation	The difficulty to evacuate the feces provokes frequent straining, which increases the risk of perianal hematomas.
Diarrhea	Repeated episodes of diarrhea can irritate and stress the anal region, which provokes the rupture of the blood vessels.
Pregnancy and childbirth	The increase in pressure in the pelvic area during pregnancy and childbirth can cause damage to the blood vessels around the anus.
Anal sex	Physical trauma or friction from anal intercourse can injure the blood vessels, provoking hematomas.
Lifting heavy objects	Lifting heavy objects can force the body and increase the pressure in the anal region, which provokes the rupture of the blood vessels.
Obesity	Excess weight increases the pressure in the perianal area, making the rupture of the blood vessels more probable.
Age	Older adults may have weaker blood vessels, which makes them more susceptible to injuries and hematomas.
Chronic cough	Persistent cough from conditions such as asthma or respiratory infections can force the pelvic area, which provokes perianal hematomas.
Previous perianal hematoma	Having had a perianal hematoma before increases the probability of recurrence.

Symptoms and diagnosis

A perianal hematoma causes localized pain and swelling around the anus due to the accumulation of blood under the skin. Identifying the symptoms and diagnosing the condition early can help to control and relieve the discomforts. Below, key subtopics related to the symptoms and diagnosis of perianal hematomas are presented.

Symptoms

The symptoms of a perianal hematoma are usually notable and can include:

• Pain and discomfort: A sudden and sharp pain near the anus, especially during bowel movements, when sitting or when standing.

• Swelling: A small and firm lump or swelling around the anus, which can be sensitive to touch.

• Bruising: The affected area can appear dark blue or purple in color, which indicates blood under the skin.

• Itching: The area can itch or become irritated due to the swelling.

• Inflammation: The surrounding skin can appear red or inflamed, especially if there is additional irritation or infection.

Diagnosis

The diagnosis of a perianal hematoma involves a physical examination and, sometimes, additional tests:

• Physical examination: The doctor generally will perform a visual and manual examination to verify the swelling, the sensitivity and the size of the hematoma. He can ask about the appearance of the pain and any recent activity that may have contributed.

• Digital rectal examination: In some cases, a digital rectal examination can be performed to rule out other conditions, such as hemorrhoids or anal fissures, and to confirm the presence of the hematoma.

• Imaging (if necessary): In rare cases, imaging such as ultrasound can be used to evaluate the extent of the hematoma or rule out other causes of pain.

Treatment options

• Home care: Use pain relievers such as ibuprofen and warm sitz baths to reduce pain and inflammation.

• Cold compress: Apply ice to reduce swelling and numb the pain.

• Topical ointments: Use creams such as hydrocortisone or witch hazel for relief.

• Diet rich in fiber: Avoid constipation to avoid more straining during bowel movements.

• Pain medications: Stronger pain relievers can be prescribed for intense discomforts.

• Surgical drainage: For large or painful hematomas, drainage may be necessary.

Summary

A perianal hematoma causes pain and swelling around the anus due to the accumulation of blood under the skin. Treatment generally includes home remedies such as pain relievers, warm sitz baths, cold compresses and topical ointments. A diet rich in fiber helps to prevent constipation. In severe cases, drainage or surgical removal may be necessary to relieve the symptoms and promote healing.
