Abstract :
Introduction: External genitalia of male is common site for rashes, itching and minor infections. Because of its anatomical variation, the area is always warm, moist and occluded, which predisposes to occur many dematoses. These dermatoses can be divided into two groups: venereal dermatoses and nonvenereal dermatoses. Non-venereal dermatoses are the diseases which are not sexually transmitted.
Aims and Objectives: 1: To study the pattern of non-venereal dermatoses of adult male genitalia of patients of age 18 years and above; 2: To study frequency of various non-venereal dermatoses among that population.
Materials and Methods: The study was conducted in the Department of Dermatology, Silchar Medical College & Hospital, Silchar, Assam over a period of one year extending from 1st June 2018 to 31st May 2019 after satisfying all the inclusion and exclusion criteria. It was a clinical observational study (cross sectional study).
Results and Observations: In the study, we came across 152 male patients of age 18 years and above. The prevalence of non-venereal dermatoses of male genitalia was found to be 54 per 10,000 populations. The mean age of presentation was 35.5 years. Pearly penile papule was the most common presentation among normal variants with 5.9% patients. Among inflammatory dermatoses eczematous dermatoses was most common dermatoses with 14.47% patient. Among miscellaneous cutaneous genital conditions, vitiligo was the only dermatoses we found with 17.11% patients. Scabies was the most common among infections and infestations with 9.9% patient. Sebaceous cyst was the most common benign tumour with 3.3% patient. Among pre-cancerous lesions, we found 2(1.3%) cases of porokeratosis and 1(0.66%) case of penile horn. We found 3 cases of squamous cell carcinoma (2%) in our study.
Conclusion: With the knowledge of clinical pattern of the non-venereal dermatoses in an area, clinical diagnosis of common dermatoses can be made easily. It is a common misbelieve among the patients that all dermatoses occurring in the genitalia are manifestations of sexually transmitted diseases. So, proper knowledge of these non-venereal dermatoses helps to create awareness among patients
