An Unusual Association of Adult T-Cell Leukemia/Lymphoma With Hyalohyphomycosis.

Infection by human T-cell lymphotropic virus (HTLV-1) causes deregulation of the immune system, which makes the infected individuals more susceptible to infectious diseases. Immune deregulation is even more pronounced in HTLV-1 carriers with adult T-cell leukemia/lymphoma (ATLL), which results in frequent opportunistic infections. Hyalohyphomycosis is a rare subcutaneous mycosis which is more commonly associated with immunocompromised patients.
