Verrucous skin lesions or subcutaneous abscesses may develop when disseminated disease occurs from a primary pulmonary infection. Primary cutaneous involvement is rare. Wilson et al reviewed this subject and described such an instance.1 They could find only one previous case in the literature described by Guy and Jacob.2 Subsequently, three other cases of primary cutaneous disease have been reported.3-5 This report will summarize the findings in three additional individuals with primary cutaneous coccidioidomycosis.
