A 20-year-old woman with myelomeningocele presented with acute right-ear pain and right hemiplegia which improved, but then progressively deteriorated. Surgery, after MRI, revealed a large arteriovenous malformation (AVM) involving the right side of the upper cervical cord and brainstem. The woman also had two epidermal nevi at the same site as the spinal cord AVMs. There has been no previous report of an association of myelomeningocele, spinal cord AVMs and epidermal nevi syndrome. The same location of the nevus and spinal cord AVMs, with a proposed common pathogenesis, raise the possibility that the association may be more than chance occurrence. Spinal cord AVMs should be considered in patients with myelomeningocele and similar clinical features.

Melanoma of the ear canal is extremely rare; due to its hidden area, most would present late in their history. We present the first case reported, of a black pigment foreign body mimicking a melanoma in the external auditory canal. A 14 year old Chinese male presented with right sided otalgia and itch. Otoscopic examination revealed an irregular black naevus in the right auditory canal. An intraoperative excision showed a black pigment foreign body giant cell reaction. Clinicians should be aware of the possibility of a foreign body granuloma of the ear canal that might mimic a melanoma.
