Trigeminal trophic syndrome in a C2 nerve distribution

A 98-year-old woman with longstanding cardiovascular disease and noninsulin-dependent diabetes mellitus was admitted to the hospital for evaluation of a chronic, nonhealing, postauricular ulceration. History revealed an episode of right-sided unilateral tinnitus approximately two years prior prompting otolaryngology evaluation and external auditory canal debridement. Within weeks of the procedure, a small, pruritic, hypoalgesic ulcer developed over the right posterolateral scalp which rapidly expanded in size over the proceeding months before eventually stabilizing.
