It is reported that leukemia accounts for only 4% of new cancer cases in males and 3% in females. Nevertheless, leukemia is the most common malignancy in children and adolescents. Childhood leukemia is typically diagnosed by pediatricians or family doctors. This report presents a case of leukemia in a 14-year-old male, initially suspected by a dentist at a dental hospital, with the diagnosis confirmed by a complete blood count laboratory test. Gingival enlargement and petechiae throughout the body&mdash;especially on the face and arms&mdash;were key signs leading to suspicion and diagnosis, which had previously been overlooked by the family doctor and an otorhinolaryngology (ENT) consultant. </span></span></span></div> Gingival Enlargement, Leukemia, Oral Diagnosis, Petechiae 588 594 http://ijpho.ssu.ac.ir/browse.php?a_code=A-10-1114-1&slc_lang=en&sid=1 Hussein Fathy Abo-elkheir Hussein Fathy Abo-elkheir hussein.fathy@mu.edu.eg 0009-0009-4013-9131 Yes Assistant lecturer Faculty of Dentistry, Minia University, Egypt Assistant lecturer Faculty of Dentistry, Minia University, Egypt Ahmed Ashraf El-sayed Ahmed Ashraf El-sayed ahmedashraf5678@gmail.com 0009-0008-0360-9205 No Resident, Hospital of faculty of Dentistry, Minia University, Egypt Resident, Hospital of faculty of Dentistry, Minia University, Egypt Ahmed Khalil Ahmed Khalil ahmedabdallahuss@yahoo.com 0000-0003-0060-6785 No Professor, Faculty Dentistry, Minia University, Egypt Professor, Faculty Dentistry, Minia University, Egypt
