IgA pemphigus includes subcorneal pustular dermatosis (SPD)-type and intraepidermal neutrophilic IgA dermatosis (IEN)-type. Cases of IgG/IgA pemphigus have recently been documented1. Nonetheless, individual reports of IgA pemphigus indicate considerable heterogeneity.
Neuromyelitis optica (NMO, also eponymously known as Devic’s disease) is an immune‐mediated demyelinating disease of the central nervous system that can lead to significant disability. Pediatric NMO is a rare disorder often reported after an infection. The authors report a 16year-old female patient with pemphigus foliaceus who developed subacute optic neuritis followed by cervical transverse myelitis. Restricted distribution of the lesions in the optic nerve and spinal cord was confirmed by ophthalmological evaluation and magnetic resonance imaging of the brain and spinal cord. She was started on intravenous methylprednisolone and then given a maintenance oral prednisone. Subsequently, she was treated with a nonsteroidal immunosuppressant, mycophenolate mofetil, with a target dose of 1000mg twice a day. Over the course of months, patient noted significant recovery of previous deficits and resolution of the cervical cord enhancement, expansion and cystic dilatation that was previously seen. This case is noteworthy for being the first patient reported with neuromyelitis optica associated with pemphigus foliaceus.
