ABSTRACT

Nonvenereal genital dermatoses (NVGD) are dermatological conditions that can mimic sexually transmitted infections (STIs), leading to misdiagnosis and unnecessary anxiety. The objective is to determine the prevalence of NVGD. This was an observational, descriptive study conducted in the Department of Dermatology, Venereology, and Leprology, Dhanalakshmi Srinivasan Medical College and Hospital, Tamil Nadu. During the 12-month study, 350 patients (2.4%) presented with genital complaints. Among them, 106 (30.3%) were diagnosed with STIs, while 244 (69.7%) had NVGD and were enrolled in the study. The overall prevalence of NVGD was found to be 69% among patients presented with genital complaints. The most affected age group was 31-40 years (32.0%). The mean age of patients was 39.1 years. Males (52.9%) were slightly more affected than females (47.1%). Most patients (56.6%) were from rural areas, and 60.3% were married. Infections and infestations were the most common NVGD category (34.8%), with scabies (13.1%) and tinea cruris (13.1%) being the predominant conditions. Eczematous disorders accounted for 20.1%, primarily lichen simplex chronicus (13.9%). Sclerosing disorders, mainly lichen sclerosus, were more frequent in females (15.7%) than males (6.2%). Other conditions included pigmentary disorders (8.6%), physiological conditions (8.6%), papulosquamous disorders (5.3%), lichenoid disorders (4.1%), and drug reactions (4.1%). Malignancies were rare (0.8%), with only two cases of squamous cell carcinoma. Vascular lesions (1.2%) and miscellaneous conditions (1.6%) were also observed. This study highlights the significant burden of NVGD, emphasizing the need for awareness, accurate diagnosis, and appropriate management to prevent misdiagnosis and psychological distress.
