What you need to know

  • Suspect inflammatory skin diseases in women with itching in the genital area

  • A history of using feminine hygiene products, latex condoms, lubricants, or fragrances may suggest irritant contact dermatitis

  • Look for concomitant skin lesions elsewhere on the body which may provide clues to a diagnosis of seborrhoeic dermatitis, psoriasis, or lichen planus
