Primary cutaneous coccidioidomycosis in agricultural workers.

Each of two Filipino agricultural workers experienced coccidioidal infection, characterized by a solitary skin lesion, by regional lymphadenopathy, and by a benign clinical course, without evidence of involvement of the lungs or other viscera. It is believed that these are cases of primary cutaneous coccidioidomycosis incurred under "natural" conditions. A similar interpretation seems acceptable for at least six other reported cases.
