n.
itching. Mediated by histamine and other vasoactive chemicals, it is the predominant symptom of atopic eczema, lichen planus, and many other skin diseases. It also occurs in the elderly and may be a manifestation of psychological illness. Perineal itching is common: itching of the vulva in women (pruritus vulvae) may be accompanied by itching of the anal region (pruritus ani), although the latter is more common in men. Causes of perineal itching include poor hygiene, candidosis, threadworm, and itchy skin diseases (such as eczema). Pruritus also occurs as a symptom of certain systemic disorders, such as chronic renal failure, cholestasis, and iron deficiency. Treatment of pruritus is determined by the cause.
