Patient case (clinical description): A 27-year-old woman comes to the dermatology clinic with skin rash and oral ulcers.  The rashes are mildly itchy. The patient has no other medical conditions and takes no medications.  Vital signs are normal.  On examination, there are pink papules symmetrically distributed over the anterior surfaces of the shins and ankles. There are some white ulcerated papules on her buccal mucosa. She is in relationship with her boyfriend and has only one sexual partner. Her boyfriend uses condoms. She smokes 1 to 2 cigarettes a day and drinks a beer daily. Biopsy reveals prominent hyperkeratosis with a thickened granular layer.  There is an infiltration of mononuclear cells in the superficial dermis that involves the overlying epidermis. The rete ridges have a sawtooth appearance.

Patient's own account: I went to the dermatologist because I had rashes on my skin and ulcers in my mouth. The rashes were not that itchy. I don't get it! I'm 27, I don't take medication, nor I don't have any other illnesses. My vitals were normal. My doc told me there were pink spots on the back of my throat. I'm heterosexual and have been only with my boyfriend and he uses condoms. I smoke 1 or 2 cigarettes a day and I drink a beer to accompany it. I had a biopsy and it showed some thick and grainy skin texture. The doc said it's an immune reaction.
