Individuals with lymphocytosis who have relatives diagnosed with CLL should undergo flow cytometry for early diagnosis. In our study, a 56-year-old patient-s brother had been early diagnosed with CLL and with lymphocytosis, and the patient was diagnosed with class 1-2 CLL after 2 years. We emphasize that individuals having a family history of CLL should be closely monitored.enArticle
