Vulvitis: Or something else? Differential Diagnosis

Since the differential diagnoses according to the ICD 10 are partly not recorded, e.g. burning, vesicles or only unclear, and clinically not practicable to present, a differential diagnosis under clinically relevant aspects according to symptoms is presented under the item “Further”, whereby a strict separation between vulva and vagina is not possible and also not useful. Endocrine, nutritional, and metabolic diseases (E00-E90).

Skin and subcutaneous (L00-L99).

  • Abscess
  • Acne conglobata – most severe form of acne; there are all efflorescences, some fistula comedones, especially on the back and neck.
  • Acne inversa (also spelled acne inversa; synonyms: Acnetetrade; Hidradenitis suppurativa (misleading term, as the disease does not originate from the sweat glands, but from the sebaceous glands and terminal hair follicles), Pyodermia fistulans sinifica, sweat gland abscess) – chronic inflammatory and episodic skin disease; preferred sites of manifestation are submammary, genital and perianal; perifolliculitis (caused by bacteria (mostly Staphylococcus aureus)) especially in the axillae and groin and a pilonidal sinus lead to pronounced scarring overall.
  • Allergies
  • Allergic contact dermatitis – sensitization to contact allergens (e.g. fragrances, preservatives, ingredients of cosmetics and externals).
  • Dermatitis (inflammatory reaction of the skin).
  • Eczema: vulvar eczema (clinical picture: erythema (areal redness of the skin), lichenification (areal leathery change of the skin), itching; possibly also swelling and fissures).
    • Manifestation of atopic eczema.
    • Irritative-toxic and allergic contact eczema (see above).
