Answer:
Since the patient had recently initiated antiretroviral therapy, it could be the suspicion of an inflammatory immune reconstitution syndrome, and a differential diagnosis would be needed to determine the most likely type of opportunistic infections and neoplasms.
Explanation:
Inflammatory immune reconstitution syndrome can be defined as the onset or worsening of pre-existing infections, autoimmune diseases, and is a consequence of the restoration of the antigen-specific immune response prompted after starting the antiretroviral treatment seen in some HIV positive patients. It is very difficult to know the incidence of this syndrome.
