BACKGROUNDMost dermatological diseases generally occur elsewhere and also involve the genitalia. If the lesion is present exclusively on genitalia, it is a difficult task for the treating doctor to differentiate non venereal from venereal genital lesions.Aim is to study the clinical pattern and prevalence of non-venereal genital dermatoses. MATERIALS AND METHODSIt is a descriptive study of adult new cases with genital lesions attending Skin and STD Outpatient Clinic of Coimbatore Medical College Hospital for a period of one year from August 2013 to July 2014. Clearance was obtained from Ethical Committee. RESULTSA total of 150 cases (114 males, 36 females) with non-venereal genital dermatoses were encountered in our study. Prevalence of the non-venereal genital dermatoses in the study was 2.6 per 1000 cases. Male-to-Female ratio of patients in our study was 3.16:1. Majority of the patients were found in the age group of 33 to 42 years [42 (28%)]. Commonest non-venereal genital dermatosis was found to be scabies occurring in 19 (12.6%) patients. Pearly penile papule was found to be more common [10 (6.6%)] among benign conditions and normal variants. Among inflammatory conditions and miscellaneous groups, contact dermatitis and vitiligo were the commonest conditions respectively. One case of verrucous carcinoma of penis was seen. CONCLUSIONAll lesions occurring over genitalia are not sexually transmitted. Scabies was the most common non-venereal genital dermatosis in our study. Identifying the common non-venereal genital conditions will also remove venereophobia.

Proteus syndrome is a rare hamartomatous disorder characterized by various cutaneous and subcutaneous lesions, including vascular malformations, lipomas, hyperpigmentation, and several types of nevi. Partial gigantism with limb or digital overgrowth is pathognomonic of Proteus syndrome. We report a case of proteus syndrome in a 45 year old man, who presented with hypertrophy of index finger of both hands and middle, ring finger of left hand, verrucous lesions over left axilla and two firm swellings over left palm for the past 15 years. Clinical findings, histopathology and imaging studies fulfilled the criteria of proteus syndrome which is rarely reported in literature.
