Cutaneous Larva Migrans

I recently had a case that was solved using Visual Dx. I had a young male patient present with a pruritic rash on the bottom of his foot. It was remarkable in that it was unilateral and had an unusual linear wrapping appearance. I asked him about any recent barefoot walking outside, and he denied anything like this. I thought it might have been a tinea infection and prescribed a topical antifungal. The patient called back 2 days later and told me he had been to Puerto Rico a few weeks prior to our visit, but it had escaped his mind at the time of our visit. This made me think the initial diagnosis was likely incorrect, and the possibility of a parasitic infection entered my mind. I used Visual Dx and input the pertinent information and saw pictures of cutaneous larva migrans on the website that looked exactly like what my patient had – and the diagnosis was made!
