Food Hypersensitivity

Most insects have a stinging apparatus at the tail end of their abdominal segment and can deliver venom. The venom can usually result in pain, erythema, abscess, or allergic reaction in human tissues such as the skin and even the lips. The presentation of lip abscess, especially in the vermilion, is rare and needs to be appropriately managed. A 39-year-old prediabetic male presented with a swollen right lower lip stung by an insect six days before the consult. The swelling started as a vesicle which became bigger, then burst, exuding a yellowish fluid and blood. The swollen area became more significant, and pain was felt. The clinical presentation was that of a lower lip abscess. Adequate antibiotics were prescribed along with a corticosteroid and a topical antiseptic. The treatment was essential to prevent the dissemination of infection and the likelihood of tissue necrosis. This case report is presented as a rare clinical case of a lower lip abscess due to an insect sting with spontaneous drainage after treatment in a prediabetic male. The dentist and clinician needed to identify this condition and to manage the case properly.
