To the side of these light areas are patchy light areas with irregular and poorly defined borders. Diseases that may explain these X-ray findings include lung abscesses, chronic pulmonary coccidioidomycosis, chronic pulmonary tuberculosis, chronic pulmonary histoplasmosis, and others. Erythema nodosum usually occurs in association with specific infections, inflammatory conditions, or medications. It consists of painful, hot, red skin lumps, usually over the shins. People with erythema nodosum should be evaluated for other disease processes.
Coccidioidomycosis is most commonly a lung infection, but it can also infect the skin.
Cutaneous coccidioidomycosis on the forehead is pictured here. This occurs more frequently in warmer climates, including California and the Southwestern United States.
