title: A syndrome of multiple immune autoreactivity. A breakdown in immune regulation.
abstract: The clinical findings of pemphigus vulgaris, rheumatoid arthritis, and Sjögren's syndrome were found in a patient displaying immunological abnormalities found in pemphigus vulgaris, systemic lupus erythematosus, rheumatoid arthritis, and Hashimoto's thyroiditis. Some of the antigen-antibody systems detected in this case were further identified. Our patient may be an example of severe failure in immune regulation.
