insect bite

Diagnosis: Insect bite reaction / Cellulitis

Comments: A 13 year old girl awoke 5 days earlier with 2 small red bumps in the left popliteas fossa. The papules became painful and expanded beyond the pen marks drawn by the patient. (Note the faint lines.) There was a large area of faint erythema, extending beyond the 2 dark red indurated plaques, that was outlined by her doctor in dark black ink. Although it was difficult to distinguish a possible toxic reaction from the bites from secondary infection, she was treated with an oral antistaphylococcal antibiotic, and the lesions cleared over the subsequent week.
