HTLV-1 is also associated with a CD4 T-cell malignancy denominated adult T-cell leukemia/lymphoma (ATLL) [18], with inflammatory disorders, such as uveitis, arthropathy, xerosis, polymyositis, Sjogrën syndrome, and pulmonary disturbances (bronchitis, bronchiolitis, and bronchiectasis), in addition to an increased frequency of opportunistic infections, including strongyloidiasis, tuberculosis, crusted scabies, and infective dermatitis by Staphylococcus aureus and/or β-hemolytic Streptococcus [19,20,21,22,23]. Here, CD4 is linked to adult T-cell leukemia/lymphoma.
