This article reviews the salient clinical features, evaluation, and treatment of mycotic and bacterial infections of the perianal and contiguous zones of the human body. The perianal region is an intertriginous zone. The heat and moisture inherent within these regions are conducive to the establishment of mycotic infections. Their proximity to the genital regions where fungal infections are more common may facilitate infection toward the perineal and perianal regions. Fungal infections mainly involve the superficial skin layers and are caused by dermatophytes or yeast. Dermatophytes are multicellular filaments, which form hyphae and spores for reproduction.

A yeast infection develops when Candida fungi, which is a type of yeast, grow uncontrollably on the surface of the skin or in mucous membranes inside the body. People can develop yeast infections anywhere inside or outside of their body, including the mouth, throat, vagina, penis, or anus. An anal yeast infection often causes intense and persistent anal itching , also called pruritus ani.
Enlarged hemorrhoids cause the leakage of moisture, stool, and fungus. Repeated wiping, cleaning, scratching, and the use of harsh cleaners make the itching worse. It is frequently worse at night.
Candidiasis is a yeast infection, also known as thrush. The most common cause of thrush is a yeast or fungus called Candida albicans. Most women will experience thrush at some point in their life. Thrush affects mucus membranes such as the head of the penis, inside of the vagina, the inside of the anus or occasionally inside the mouth and throat.
