These disorders are the cause of considerable concern to patients causing mental distress and guilt feeling in them. Nonvenereal dermatoses are quiet often a diagnostic dilemma to the treating physician also. The aim was to determine clinical and epidemiological pattern of nonvenereal dermatoses of male external genitalia.Methods: This was a descriptive study of 50 consecutive male patients over age of 18 years, with genital lesions of nonvenereal origin, attending the skin outpatient department of BTGH, Kalaburagi. Study was done for a period of 6 months.Results: The study included 50 male patients with nonvenereal genital lesions. A total of 14 nonvenereal genital dermatoses were noted. The most common nonvenereal genital dermatoses were vitiligo (20%), fixed drug eruptions (16%), scabies (14%), pearly penile papule (10%), and dermatophytoses (10%). Other dermatoses included psoriasis, plasma cell balanitis or Zoon's balanitis, lichen simplex chronicus, lymphangioma circumscriptum, squamous cell carcinoma, scrotal dermatitis, lichen planus, steatocystoma multiplex and candidiasis.Conclusions:This study helps in understanding the etiological causes of nonvenereal genital dermatoses and their pattern in this region.
