I have what started out as a small poison ivy looking rash and a few mosquito bite looking things on my left leg that have now spread into large and small sores all over my body. The initial rashes sat dormant for about a month before they started swelling up and then started to spread. Both legs, theighs, elbows and arms first then feet, chest and neck too now. Nothing on genitals or face yet. I spent the last 4 months in costa rica and noticed the rash first there.
The sores don't look exactly like MCV but can not find anything else it could be either. the sores aren't quite as perfectly rounded or domed. they are more like open sores - i think i scratch a lot though - than closed domes. they excrete a clear yellow fluid which hardens and closes the sore. no white "core" comes out.
can MCV be contracted on the leg in adults or is it generally only congenital? can anyone think of a (tropical) differential diagnosis?
treatment so far has been, cephalahexin-no effect, and freezing-had a small effect but did not completely remove the frozen sores.
