The most notable feature is a very distinct redness around the anus, and other signs of inflammation which can include swelling and itching at the site. Other associated symptoms with perianal cellulitis include pain when defecating and bleeding. These symptoms can often be confused with other skin conditions, such as diaper rash, eczema, psoriasis, hemorrhoids, and more. These symptoms can cause extreme discomfort, especially in diaper-wearing infants, and serious complications can arise if left untreated. In about 10% of cases, balanitis or vulvovaginitis can develop concomitantly. In even rarer instances, tonsillopharyngitis can develop concomitantly as well.Complications most often occur when perianal cellulitis remains undiagnosed and untreated for an extended period of time. In cases where perianal cellulitis is left untreated, it can cause more serious symptoms such as abscess formation and rheumatic fever. Additionally, untreated perianal cellulitis poses a risk of transmission to other people, such as caretakers or family members. Perianal cellulitis can also cause post-streptococcal nephritis, which should be monitored with urinalysis to assess kidney function. Diagnosis
The diagnosis of perianal cellulitis is made either through a rapid strep test or by swabbing the affected areas for a bacterial culture indicating infection by group A β-hemolytic streptococci. In order to confirm diagnosis of perianal streptococcal dermatitis, the anus and genitalia require examination followed by bacterial swabbing of the exudate from the affected area is preferred. The swabs will be sent for microbiological analysis of the culture to confirm the growth of group A β-hemolytic streptococci.
Tufted folliculitis presents with dolls hair-like bundling of follicular units, and is seen in a wide range of scarring conditions including chronic staphylococcal infection, chronic lupus erythematosus, lichen planopilaris, Graham-Little syndrome, folliculitis decalvans, acne keloidalis nuchae, immunobullous disorders, and dissecting cellulitis. : 761
