A Case of Paederus Dermatitis: CASE REPORT
A 33-year-old Korean man who had been in Kenya on missionary work was presented with a linear, brownish hyperpigmentation with background hypopigmentation on his left cheek and left hand (Fig. 1). He woke up a month ago to discover erythematous, pinhead-sized blisters in a linear pattern on his left cheek (Fig. 2) and left hand, accompanied by a stinging and burning sensation. The local clinician diagnosed it as Paederus dermatitis caused by ” Le Nairobi fly. He told us that the local population called this clinical picture ” Lght burn” and ” ic Nairobi fly” indicating Paederus sabaeus or Paederus crebrepunctatus. This is commonly seen in Kenya, and the insect causes Paederus dermatitis simply by only brushing against the skin or being crushed onto it, usually while the victims are asleep.
