REPORT OF A CASE
A 22-year-old man presented with a 3-week history of pruritic lesions on his feet acquired while on a scubadiving vacation in Jamaica. In spite of being cautioned, he walked barefoot through puddles after a rain. Three to four days after returning home, he noted erythematous papules on both feet that progressed to an irregular linear lesion. He initially went to a college infirmary where he was treated with topical lindane without improvement. Physical examination revealed an erythematous firm serpiginous and excoriated rash on the dorsum and plantar surface of the left foot and plantar surface of the right foot (Figs 1 and 2).
