Paraneoplastic pemphigus (PNP) is a rare and often fatal autoimmune blistering disease accompanied by both benign and malignant neoplasms. Usually, oral, skin, and mucosal lesions are the earliest manifestations shown by PNP patients. Oral ulcers are initial lesions in various autoimmune diseases like pemphigus, bullous pemphigoid, erythema multiforme, graft-versus-host, lichen planus, it does not improved despite of high-dose steroid therapy. We report a-35-year-old female who presented oral ulceration, lip crust and skin lesions. By doing several examinations, such as enzyme-linked immunosorbent assay, incisional biopsy with indirect immunofluorescence, she was diagnosed PNP with non-Hodgkin's lymphoma on pancreas.

Vestibular schwannoma, also known as acoustic neuroma, is a rare benign brainstem tumor surrounding the vestibular division of the 8th cranial nerve. The presenting symptoms are hearing loss, tinnitus, and dizziness. Unabated growth can compress 5th (trigeminal nerve) and 7th (facial nerve) cranial nerve, which can cause nerve dysfunction such as orofacial pain, sensory abnormalities, or trigeminal neuralgia. We report a 51-year-old woman who presented with orofacial dysesthesia on her left side of the face with abnormal findings on 5th cranial nerve and 8th (vestibulocochlear nerve) cranial nerve examination. Brain magnetic resonance imaging scan revealed cerebellopontine angle tumor. She was referred to a neurosurgeon and diagnosed with vestibular schwannoma.It is very important to take a careful history taking for the accurate diagnosis. If there are other neurologic symptoms besides dysesthesia, we should suspect brain tumors. Symptoms of suspected vestibular schwannoma includehearing loss, tinnitus and dizziness.Although previous imagings and examinations were normal, the clinicians should re-evaluate the patient if symptoms are getting worse or the new symptoms appear. Also if there are neurologic deficits on 5th, 7th, and 8th cranial nerves, brain MRI must be taken.
