A 15-year-old female admitted with the complaints of redness, itching, burning sensation and kissing pattern of lesions on left hand elbow since 20 days and a circular rash since 5 days after intake of fish. Initially, it appeared as a rash. Erythematous papules were formed initially which were peculiar and irritating that passed through various stages to form an erythematous plaque with many vesicles that decayed to form sterile pustules. Intake of sea food resulted in worsening the rash and eventually turned into invasive tinea infection.The patient was evaluated by two local doctors but was not diagnosed. Finally, it was determined that the Nairobi fly's deadly hemolymph, pederin, was to blame (Paederus). The rash mainly affects body portions that aren't covered by clothing; recovery takes 7 to 28 days, and skin darkening is common.Typical anti-vector precautions, such as bed nets, long-sleeve clothes, and avoiding fluorescent lights, are among the preventive measures. If beetles are found on the skin, brush them off instead of crushing them to prevent dermatitis. Antibiotics, steroids, and antihistamines may be used in addition to promptly cleaning the afflicted region and applying cold, moist compresses.
