Abstract

BACKGROUND: Most dermatological diseases generally occur elsewhere and also involve the genitalia. When other sites are involved the diagnosis is straightforward. If the lesion is present exclusively on genitalia, it is a difficult task for the treating doctor to differentiate nonvenereal from venereal genital lesions. AIM AND OBJECTIVE: To study the clinical pattern and prevalence of non venereal genital dermatoses MATERIALS AND METHODS: It is a descriptive study of adult new cases with genital lesions (which includes male and female patients above 12 years of age and excludes patients below 12 years of age, transgenders, patients presenting with classical Sexually transmitted infection and HIV, VDRL reactive patients) attending SKIN and STD out patient clinic of Coimbatore Medical College Hospital for a period of one year from August 2013 to July 2014. RESULTS: A total of 150 cases (114 males, 36 females) with non venereal genital dermatoses were encountered in our study. Prevalence of the non venerealgenital dermatoses in the study was 2.6 per 1000 cases. Male to Female ratio of patients in our study was 3.16 : 1. Majority of the patients were found in the age group of 33 to 42 years [42 (28%)].Commonest NVGD was found to be scabies occuring in 19 (12.6%) patients.pearly penile papule was found to be more common [10 (6.6%)] among benign conditions and normal variants. Among inflammatory conditions and miscellaneous groups, contact dermatitis and vitiligo were the commonest conditions respectively. One case of verrucous carcinoma of penis was seen. Among four categories classified according to the site of involvement, Genitalia alone was found to be involved in more number of patients [87(58%)] Scrotum and Labium majora were the most common site of involvement in male and female genitalia respectively. CONCLUSION: All lesions occurring over genitalia are not sexually transmitted .Many other non venereal conditions can occur over the genitalia. All cliniciansshould have an open mind to look for these conditions and treat with appropriate drugs.Scabies was the most common nonvenereal genital dermatosis in our study. Knowing about the prevalence, clinical and etiological characteristics of various nonvenereal genital dermatoses are helpful in arriving at a diagnosis and also creating awareness among patients to improve their personal hygiene and social habits.
