Human T-cell lymphotropic virus type 1 , 2 (HTLV-1, 2) is endemic in Particular Areas of the world in which it is associated with myeloid leukemia.In this study, we described the prevalence of HTLV-1, 2 in myeloid leukemia and Mycobacterium Tuberculosis in Iran. We have worked with tissue and blood samples for 2 years. These were the same samples which were positive for myeloid leukemia, Mycobacterium tuberculosis,HTLV and were collected from Imam Khomeini hospital in Tehran, Iran. 100 cases were investigated (58% males, 42% females), the age of these samples were within 5 to 89 years old.In 65.7 percent of the leukemia rate HTLV-1 has been positive. Five cases (54%) were myeloid leukemia, 36.4% cases were not myeloid leukemia and 3 out of 8 cases (27.9%) unclassified lymphomas, were positive respectively. All 6 cases (100%) were adults with acute T-cell leukemia/lymphoma (ATLL) and Mycobacterium tuberculosis were positive. Among all cases, just one case has been positive for chronic myeloid leukemia and myeloproliferative disruption. Positive HTLV-1- show more in older ages than younger one. At younger ages offers less than negative items. According to our results, in Iran HTLV-1, 2 is dramatically related to myeloid leukemia, and more studies are required for accurate connection with myeloma diseases and this area.
