DEAR EDITOR, A 56-year-old woman presented with a large nonhealing ulcer on the right face for 6 months (a). She had received systemic antibiotics for suspected facial cellulitis. Neurological examination revealed diminished sensation to touch, pinprick and temperature affecting the right first, second and third divisions of cranial nerve V. Radioimaging showed an infarction at the right posterior medulla oblongata (b, arrow). The crescentic ulceration involving the ala nasi was self-induced secondarily to trigeminal paraesthesia. Ophthalmological examination further revealed the under-recognized right-eye corneal erosion (c, arrows). The patient received gabapentin treatment and occlusive dressing to preserve vision. 1,2
