###Human: Is lichen sclerosus a contagious disease? ###Assistant: Hi. I have thoroughly gone through your case and can well understand your genuine health concerns. Thanks for taking time to upload latest pictures (attachment removed to protect patient identity) of the lesions on both partner's genitalia. Lichen sclerosus is a benign condition but it may also transform into squamous cell carcinoma if not treated properly.  Yes, penile lesion may be related to the vulvar lesion. But, lichen sclerosus is not a contagious disease. Did you get the biopsy of the lesions shown in the pictures, both your's and your partner's? If not, please get them tested.  You need not worry as all the symptoms are related to this disease. Sexual intercourse and urination problems are all due to this lesion and this is a real pain when a patient gets this kind of fissure along with itching of lichen. If not treated it may cause permanent scarring and that is very painful situation. Biopsy of the lesions on penis and vulva, highly recommended. Lichen sclerosus. 1. Patient education, it is a long-term disease and may relapse even after total relief. You need to be very calm and consistent in treatment. 2. Hydrocortisone ointment (topical Clobetasol propionate) is the treatment of choice to reduce scarring and to get relief from fissuring. It will reduce progression of the disease. 3. Avoid scratching and keep the vulva and penis clean and dry. 4. If ever topical corticosteroid fails we add intralesional corticosteroids, or I usually go for a second line therapy as calcineurin inhibitors. Stay away from sexual intercourse until you get symptom free. For further queries consult a general practitioner online.--->
