A possible case of coccidioidomycosis from the Los Muertos site, Tempe, Arizona

Abstract

Coccidioidomycosis is a fungal disease endemic to southwestern North America and parts of Central and South America. Coccidioidomycosis frequently disseminates to the human skeleton and produces mostly lytic skeletal lesions. However, this disease is infrequently described within archaeological populations. As a result, it is important to report potential cases in order to improve current understanding of the appearance and distribution of lesions resulting from coccidioidomycosis in archaeological specimens. This study describes skeletal lesions in an adult male recovered from the Los Muertos site, Tempe, Arizona (AD 500–1450). These lesions are present on the inferior border of the left scapular spine, the medial portion of the left first metacarpal head, and the medial portion of the right first metatarsal. The lesions are predominantly lytic with sclerotic and, in some cases, healed cortical bone distributed around their margins. Evidence of skeletal healing is recorded within the destructive focus of one lesion. Geographical information on pathogen endemism, overall lesion distribution, and agricultural-era Hohokom behaviour suggest that coccidioidomycosis is the most likely diagnostic option for these lesions. Mounting evidence for possible infections in the palaeopathological literature, combined with high frequencies of nutritional stress levels in endemic regions, suggests that coccidioidomycosis contributed at least moderately to morbidity in the American Southwest.
