Coccidioidomycosis?,”Coccidioidomycosis is endemic in the southwestern US, as well as Central and South AMerica (a patient from Arizona/California should make you think of coccidioidomycosis). Primary pulmonary infection has non-specific features, such as fever, fatigue, dry cough, weight loss, and pleuritic chest pain. Cutaneous findings, such as erythema multiforme and erythema nodosum, as well as arthralgias
are common.”
