This paper reports a case of insect bite dermatitis treated with fire dragon cupping. The patient presented with patchy circular erythema on the lateral aspects of both lower extremities

predominantly from the lateral aspect of the right thigh to the buttock. Slight desquamation was observed at the center of the local erythema

accompanied by swelling

induration

tenderness

increased skin temperature

and intolerable itching and burning pain. The treatment principle was to remove the pathogenic factors and detoxify

promote blood circulation and resolve erythema. Fire dragon cupping was administered once every 3 days

twice a week. After the first treatment

the patient's skin itching and burning pain were significantly relieved

erythema on both lower extremities subsided

hyperpigmentation was observed

and skin temperature returned to normal. The scores of skin symptom scale

visual analogue scale (VAS) for itching and dermatology life quality index (DLQI) were all improved. Two treatments were given

and the patient achieved near-complete resolution on day 11 of treatment

with partial residual hyperpigmentation. No recurrence was reported at 1-month follow-up.
