Diffuse Lymphocytic Infiltration Syndrome (DILS) as a Mode of Revelation of HIV: On a Case

Abstract

Diffuse Lymphocyte Infiltration Syndrome (DILS) is a rare condition observed in HIV patients, characterized by infiltration of CD8+ T lymphocytes in several organs. In this article, a case of revelation of HIV infection is presented, diagnosed following bilateral parotidomegaly associated with DILS. The patient, aged 60, presented a progressive deterioration in general condition, significant asthenia, weight loss, and local symptoms including bilateral parotid swelling, cervical lymphadenopathy, and intermittent fever. Investigations revealed HIV-1 seropositivity, lymphocytosis with high T-CD8+ levels, salivary gland enlargement on imaging, and benign lymphoepithelial lesions on parotid biopsy. The diagnostic criteria for DILS were met, highlighting the importance of salivary gland involvement in this syndrome. Treatment with HAART resulted in significant regression of symptoms. In summary, DILS represents a multisystem complication of HIV, requiring appropriate management including antiretroviral treatment to improve patient prognosis.
