18 yo girl just returned from Costa Rica

This 18 year old girl just returned from a school trip to Costa Rica. Her group explored streams and swamps. She developed asymptomatic papules and pustules on the dorsae of her feet after being in stagnant muddy water and a running stream. I am wonderind if this is a gram negative organism or a parasite. Any thoughts?


  1. Yes D, with the a brief history, sudden onset, and grouped, bilateral lesions I feel it should be of parasitic origin or an urritant phenomenon.
    Anaerobes and gram -ve ysyally are solitary and unilateral. Was a culture done. I guess that might help.

  2. This is a plant dermatitis.
