Perianal streptococcal cellulitis
Perianal streptococcal cellulitis is an inflammation of the anus and rectum caused by Streptococcus bacteria.
Streptococcal proctitis; Proctitis - streptococcal
Perianal streptococcal cellulitis usually occurs in children, often with or after strep throat, nasopharyngitis, or streptococcal skin infection (impetigo).
Children may infect the skin around the anus while cleaning the area after using the toilet or by scratching with hands that have bacteria from their mouth or nose.
- Itching, pain, or bleeding with bowel movements
- Redness around the anus
Exams and Tests
- Rectal swab culture
- Skin culture from rectal area
- Throat culture
The infection is treated with antibiotics for about 10 days, depending on how well and quickly it appears to be working. Penicillin is the most often used antibiotic in children who are not allergic to it.
Mupirocin can be applied directly to the skin (topical). Topical medicine can be used along with other antibiotics, but should not be the only treatment.
Children usually recover quickly with antibiotic treatment. It is important to contact your health care provider if your child does not get better soon on antibiotics.
When to Contact a Medical Professional
Call your health care provider if your child complains of pain in the rectal area, painful bowel movements, or other symptoms of perianal streptococcal cellulitis.
If your child is taking antibiotics for this condition and the area of redness gets worse, or the discomfort or fever are increasing, call your health care provider immediately.
Take a full course of antibiotics to eliminate the bacteria from the affected site. Careful handwashing can help prevent this and other infections caused by bacteria carried in the nose and throat.
