A female client sees a dermatologist for a skin problem. Later, the nurse reviews the client’s chart and notes that the chief complaint was intertrigo. This term refers to which condition?
A. Spontaneously occurring wheals.
B. A fungus that enters the skin’s surface, causing infection.
C. Inflammation of a hair follicle.
D. Irritation of opposing skin surfaces caused by friction.
Correct Answer: D. Irritation of opposing skin surfaces caused by friction.
Intertrigo refers to irritation of opposing skin surfaces caused by friction. Intertrigo is a superficial inflammatory skin condition of the skin’s flexural surfaces, prompted or irritated by warm temperatures, friction, moisture, maceration, and poor ventilation. Characteristically, the lesions are erythematous patches of various intensity with secondary lesions appearing as the condition progresses or is manipulated.
Option A: Spontaneously occurring wheals occur in hives. Contact urticaria (CU) is a transient wheal and flare reaction that occurs within 10 to 60 minutes at the site of contact of the offending agent and completely resolves within 24 hours. The risk for developing CU increases when there is an interruption of the stratum corneum due to filaggrin gene mutations or skin irritants.
Option B: A fungus that enters the skin surface and causes infection is a dermatophyte. The dermatophyte’s ability to attach to the keratinized tissue of skin forms the basis for dermatophytosis (superficial fungal skin infections). The dermatophytes causing tinea corporis belong to genera Trichophyton, Epidermophyton, and Microsporum.
Option C: Inflammation of a hair follicle is called folliculitis. Folliculitis is a common, generally benign, skin condition in which the hair follicle becomes infected/inflamed and forms a pustule or erythematous papule of overlying hair-covered skin. While this is a non-life-threatening condition and in most cases is self-limited, it can present challenges for immunocompromised patients and in some cases progress to more severe diseases.
