Contact allergic dermatitis (allergy to eg perfumes, aerosols, can cause an allergic reaction on the upper chest and neck with erythema, and sometimes fine scale).

Psoriasis of the vulva is often manifested by shiny, glazed skin, whereas psoriasiform scale and well-demarcated borders are absent. The classic lesion is a well-demarcated, raised, red plaque with a white scaly surface. Eruptive psoriasis (guttate) is associated more with young adults and is characterized by papules 0.5-1.5 cm in diameter over the upper trunk and proximal extremities. The lesions are of a glossy erythema that is well demarcated, and sweating is impaired over the effected skin. Systemic complications are more common in women, and can include lesions beyond the genitalia, urinary retention, and aseptic meningitis.

Carcinoma in situ should be suspected if the patient has velvety red or keratotic plaques of the glans penis or prepuce, whereas invasive squamous cell carcinoma presents as a painless lump, ulcer, or fungating irregular mass. Some benign lesions, such as psoriasis and lichen planus, can mimic carcinoma in situ or squamous cell carcinoma. 42,46,47 In the early stages, squamous cell carcinoma can present as a painless lump or ulcer that progresses to thickened skin and a wart-like growth, sometimes associated with foul discharge (Figure 10A).
The vulva, like the rest of the skin, can be affected by numerous diseases of various etiologies, but its particular anatomic and physiologic characteristics create additional diagnostic and therapeutic difficulties. 3).41 Extragenital manifestations are present in 6 of cases,47 but the oral and genital mucosa are not usually affected. Well-defined and intensely erythematous ulcers or erosions appear in the variant known as erosive lichen planus, which is more common in the vulvar area, with a reported presence in between 74 76 and 95 5 of cases (Fig. B (zoom): AIDS associated KS -Presentation: symmetrical widespread cutaneous lesions that begin as one or several red to purple-red macules, rapidly progressing to papules, nodules and plaques head, neck, trunk and mucous membranes (MORE widespread that classic!) this MAY BE the presenting manifestation in HIV.
