Non-venereal dermatoses include disorders involving genitalia which are not transmitted sexually. They are more likely to be confused with venereal diseases, which leads to diagnostic dilemma to physicians. Patients usually think of that they are suffering from some venereal diseases and can be a major concern to patient. MATERIALS & METHODS: It is a descriptive study of new cases with genital lesions among adults (which includes male patients above age of 18 years and excludes patients below 18 years of age, patients presenting with classical STDs, attending SKIN & STD outpatient clinic of Chettinad hospital and research centre for a period of one year from July 2018 to August 2019. RESULTS: A total of 216 cases with non-venereal genital dermatoses were encountered in our study. Majority of the patients were found in the age group of 26 -35 years [27.8 %]. Scabies was found to be the commonest NVGD, occurring in 56 (22%) patients. Pearly Penile Papule was seen more commonly [15 (7%)], among benign conditions and normal variants. CONCLUSION: All lesions occurring over genitalia are not necessarily sexually transmitted. Many other non-venereal conditions can occur over the genitalia. All clinicians should view and examine these conditions with an open mind and treat with appropriate drugs. Scabies was commonest non venereal genital dermatoses in our study.
