Although lip abscesses are uncommonly reported in the medical literature, they may appear when they result in serious sequelae.1,2 One can assume that most cases have satisfactory outcomes without medical intervention, although some clinicians advocate treatment with intravenous antibiotics and urgent surgical drainage.2 Exogenous factors reported to induce lip abscess formation include bee stings and silicone injections for lip enhancement.3,4 Lip abscesses have also been reported in association with isotretinoin therapy for acne.5
The patient’s lesion was punctured and expressed copious pus. He was placed on treatment with cephalexin; on follow-up examination 1 week later, the site had fully resolved.
