A cross-sectional study of noninfectious - nonvenereal genital dermatoses among adult males at tertiary care hospital in South Gujarat.

Background: A number of dermatoses affect the genitalia in a unique and distinct manner. Nonvenereal dermatoses may not be restricted to genitalia alone; it may affect other body sites and mucous membranes as well. Dermatoses involving genital areas are not necessarily sexually transmitted. Skin lesions of the genitalia may be physiological, venereal, or nonvenereal in origin. Studies on genital dermatoses of only nonvenereal and noninfectious origin among adults are not commonly documented in India.

Objectives: The objectives of this study were to determine the clinical pattern and frequency of noninfectious nonvenereal genital dermatoses.

Materials and methods: A total of 261 patients with noninfectious nonvenereal genital dermatoses attending tertiary care hospital were enrolled from August 2019-July 2020. Cases of more than 18 years of age who had given informed valid consent were included in the study, whereas venereal or infectious dermatoses were excluded from this study. The diagnosis was established based on a detailed history, examination, biopsy, and relevant investigations. Data collection was done using predesigned pro forma, and analysis was perfomed using MS Excel.

Results: Maximum participants were middle aged with a mean age of 43.38 ± 9.45 years. The most common nonvenereal genital dermatoses were vitiligo (23.37%), followed by physiological conditions (19%-92%), papulosquamous dermatosis (18.77%), lichen simplex chronicus (16.48%), premalignant conditions (6.51%), vesiculobullous conditions and benign conditions (4.98%) each, adverse cutaneous drug reactions (4.21%), and malignant conditions (0.77%). About 78.54% of participants had dermatosis over genitalia only. Focal vitiligo was the most common dermatosis involving only genitalia.

Conclusions: This study is novel as participants enrolled only of noninfectious, nonvenereal genital dermatoses among males.
