It was found that the overall frequency of collagenosis was 4.4%. The frequency of JRA was 0.15%. SLE, DM and HSP was 0.03% for each, MCTD 0.08% and RHD 4.3%. All connective tissue diseases showed female predominance, except HSP where the only case reported was a boy and JRA that showed equal sex distribution. The age distribution, the commonest presentation and the laboratory aspects varied from one disease to another
