![]() ![]() Mycotic infections of the perineum may commonly present in patients with previous mycotic infections of other regions, including feet and hair. The focal clinical reaction depends on the mycotic species involved-inflammation is due to hypersensitivity to the metabolic products of the fungus as they digest and live on keratin. Satellite lesions of localized erythematous perifollicular papules or pustules may also be present within the adjacent intertriginous areas. Mycotic infection can present with annular lesions with scaly elevated borders and central clearing, or as a bright red rash in a “butterfly” distribution with superficial longitudinal fissures. Other symptoms include localized pain, chronic seepage, and excessive moisture. The most common symptom of mycotic infection of the perianal and perineal regions is pruritus. Fungal infections may account up to 40% of secondary infectious pruritus ani cases–a majority is caused by Yeast-like fungi are unicellular and propagated by budding. The most common dermatophyte species include Dermatophytes are multicellular filaments, which form hyphae and spores for reproduction. Fungal infections mainly involve the superficial skin layers and are caused by dermatophytes or yeast. Their proximity to the genital regions where fungal infections are more common may facilitate infection toward the perineal and perianal regions. The heat and moisture inherent within these regions are conducive to the establishment of mycotic infections. The perianal region is an intertriginous zone. ![]()
