Hi there, welcome to the forum. The clinical condition you are describing closely resemble Lichen planus. It
is a mucocutaneous disease that affects the skin and the oral mucosa. The cause of lichen planus is not known.
It is not contagious and does not involve any known pathogen. Some studies shown that allergic reactions to
medications for high blood pressure, heart disease and arthritis may cause lichen planus. Some Lichen planus
affects women more than men. The presence of cutaneous lesions is not constant and may wax and wane over time.
But accurate diagnosis is made only on physical examination & subsequent investigations by a health
professional. It is better to take consultation with a dermatologist. Hope this helps you. Take care.
