Summary
Diffuse infiltrative lymphocytosis syndrome (DILS), an HIV-1 complication, often presents with asymptomatic parotid swelling. Regular monitoring is crucial due to potential lymphoma development.
Area of Science:
- Immunology
- Virology
- Oncology
Background:
- Diffuse infiltrative lymphocytosis syndrome (DILS) is a subset of HIV-1 disease.
- A key characteristic of DILS is asymptomatic bilateral parotid swelling.
- Early recognition is vital as patients often seek routine dental care.
Observation:
- Presents a classic case of DILS.
- Patient exhibited bilateral parotid swellings due to lymphoepithelial cysts.
- Other findings included cervical lymphadenopathy, CD8 circulating lymphocytosis, and labial salivary gland lymphocytic infiltration.
Findings:
- The case highlights lymphoepithelial cysts as a cause of parotid swelling in DILS.
- CD8 lymphocytosis and infiltration were confirmed through laboratory and biopsy analysis.
- Previous parotid surgery did not alter the benign course of the remaining swelling.
Implications:
- Periodic observation is mandatory for DILS patients due to lymphoma risk.
- Fine-needle aspiration biopsy is recommended if any growth pattern changes occur.
- This underscores the importance of vigilant monitoring in HIV-1-associated conditions.
