Connective tissue disorders
The cardinal feature of these conditions is inflamma-tion in the connective tissue which leads to dermal atrophy or sclerosis, to arthritis, and sometimes to abnormalities in other organs. In addition, antibodies form against normal tissues and cellular components; these disorders are therefore classed as autoimmune. Many have difficulty in remembering which antibody features in which condition: Table 10.1 should help here.
The main connective tissue disorders present as a spectrum ranging from the benign cutaneous variants to severe multisystem diseases (Table 10.2).
