case_images: Regarding neurological symptoms, brain magnetic resonance imaging also showed no lesions to explain the symptoms, aside from a previously identified small vestibular schwannoma in the right internal auditory canal (Figure 1).
case_images: Laboratory results showing improvement following treatment progression. The bold arrow indicates the initiation of treatment and the day of the emergency room visit. The graph displays laboratory test results from the initiation point to the most recent data. During the course of treatment, it was observed that the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatine kinase (CK), and lactate dehydrogenase (LD) all returned to normal.

case_images: Histologic findings of left upper arm skin. a. Intermediate power view reveals parakeratosis and mild inflammatory infiltrates in the upper dermis (HE, x100). b. High power view reveals spongiosis, necrotic keratinocyte, vacuolar change of basal cells, and infiltration of chronic inflammatory cells on perivascular area and upper dermis (HE, x400).
