The Human Adenovirus (HAdV) infection could be critical in the retinoblastoma pathogenesis due to the virus and retinoblastoma 1 interactions. The objective of the current study was to investigate the possible presence of the HAdV genome in the retinoblastoma patient's tumors. Materials and Methods: In this study, we evaluated the HAdV infection in 96 pathological confirmed retinoblastoma samples. The DNA was extracted from formalin-fixed paraffin-embedded blocks, and the virus infection was assessed using polymerase chain reaction. SPSS version 22 was used for statistical analysis. Results: The mean age ± SD of the retinoblastoma patients was 28.89 ± 17 months. In addition, the demographic evaluation indicated that 43 (46.7%) of patients were female. The retinoblastoma laterality assessment indicates 87 (90.4%) unilateral and 9 (9.4%) bilateral tumors. Growth pattern analysis indicates endophytic 58 (77.3%), exophytic 8 (10.7%), and 9 (12%) of tumors with mix endophytic and exophytic patterns. The polymerase chain reaction results could not found any evidence of HAdV infection in all 96 formalin-fixed paraffin-embedded samples. Conclusions: The study results suggest that there is not any association between HAdV infection and retinoblastoma tumors in studied samples. The HAdV infection may not a concern in retinoblastoma pathogenesis. Further investigations are recommended in this field of study. 06 02 2021 10.18502/ijml.v8i2.6272 https://publish.kne-publishing.com/index.php/IJML/article/view/6272 https://publish.kne-publishing.com/index.php/IJML/article/download/6272/6033 https://publish.kne-publishing.com/index.php/IJML/article/download/6272/6033 https://ijml.ssu.ac.ir/article-1-382-en.html https://publish.kne-publishing.com/index.php/IJML/article/view/6272
