Anogenital pruritus is defined as intense itching, acute or chronic, affecting
the anal, perianal, perineal and genital skin, which is a dominant problem in the
course of various cutaneous and systemic conditions. It is one of the common,
extremely annoying symptom for which patients attend the Dermatology Outpatient
Department (OPD). Anogenital skin is highly sensitive to soaps, perfumes,
clothing and superficial trauma and it is more prone for itchy dermatoses as a
result of warmth, friction, lack of aeration, sweating and occlusive inner
garments. Anogenital pruritus is associated with a wide spectrum of diseases
which includes localized infections, infestations, inflammatory dermatoses,
allergic and irritant conditions, anorectal diseases, systemic causes,
nutritional disorders, psychological and when the cause cannot be found out it is
often termed idiopathic. Patients are highly reluctant in consulting the
physician for anogenital itch in the early stage, they usually present at a later
stage with either atypical manifestations or depigmentation and lichenification,
secondary to constant scratching. They often resort to over the counter topical
agents, particularly combination products which contain topical steroids. The
irrational use of such products results in complications like skin atrophy,
striae, incognito etc. A proper clinical history, clinical examination,
investigations like scrapping for fungus and itch mite, skin biopsy, patch test
and relevant blood investigations to rule out systemic conditions should be
carried out, when needed, to arrive at an accurate diagnosis, before treating the
patient.
