Benign lymphoepithelial cysts (BLCs) are a widely recognized cause of parotid gland swelling in HIV-infected patients. Although they are neither invasive nor associated with malignant degeneration, BLCs can become large and disfiguring. Multiple modalities have been used to control these cysts, but no ideal treatment has been identified. The current study examines the efficacy of doxycycline as a BLC sclerosant in eight patients, and nine BLCs (bilateral BLC in one patient). Follow-up ranged from 12 to 17 months in all cases. Doxycycline sclerosis controlled further cyst growth in 100% of cases with no serious complications. The BLCs became negligible or unnoticeable in two patients, and in six patients (seven BLCs) the cyst became fibrosed and showed no evidence of further growth over the follow-up period. Although further studies are needed to determine the long-term efficacy of this treatment modality, doxycycline sclerosis appears to offer a simple, safe, cost-effective, office-based therapeutic option for the treatment of BLCs in patients infected with HIV.
