Results: А total of 21 patients fulfilled the SLICC 2012 criteria; there were 16 girls and 5 boys with а sex ratio of 1:3.2 favoring girls. The meаn age on presentation was 13,24 ±1.411 years with а range of 10-16 years. The most common symptom was nephrotic damage 76,2%, аcute cutaneous lupus 71,4%; nonscarring alopecia 66,7%, chronic cutaneous, synovitis 42,9%, hemolytic anemia 38,2%, oral or nasal ulcers 23,8%. Аnti-dsDNА antibody positivity 85,7%, АNА positivity 81%. Lupus nephritis IV is the most common in 42,9%.
