Perianal cellulitis, also known as perianitis or perianal streptococcal dermatitis, is a bacterial infection affecting the lower layers of the skin around the anus. [1] [2] [3] It presents as bright redness in the skin and can be accompanied by pain, difficulty defecating, itching, and bleeding.
The legs and face are the most common sites involved, although cellulitis can occur on any part of the body. [1] The leg is typically affected following a break in the skin.

Erysipelas, a bacterial infection which primarily affects superficial dermis, and often involves superficial lymphatics. [10] Unlike cellulitis, it does not affect deeper layers of the skin. It is primarily caused by the Group A beta-hemolytic streptococci, with Streptococcus pyogenes being the most common pathogen. [10]
