Multiple myeloma in paleopathology: A critical review

Abstract

This paper provides a critical literature review concerning paleopathological evidence of multiple myeloma discovered both in the Old and in the New World. A critical assessment of the bioarchaeological and paleopathological documentary sources permitted to identify a total of 25 ascertained cases of multiple myeloma from different geographical areas in the world ranging from Prehistoric times up to the Contemporary age. The distribution of multiple myeloma findings in past times shows that the majority of cases have been discovered in the Old World (n = 18) and extend back to the Middle Ages, while the evidences in the New World (n = 7) seems to date back to the pre-Columbian era. The demographic profile suggests a sex ratio of 1.3:1, while 91.7% of affected individuals (n = 24) are adults. This critical review also discusses the diagnostic criteria and methodological issues commonly attempted in paleo-oncological research, with particular regard to the differential diagnosis of multiple myeloma. As such, the main focus of this work is to present a comprehensive and exhaustive scrutiny of the skeletal manifestations identified as multiple myeloma in order to improve the accuracy of diagnoses within the field of paleopathology.
