سختی پالئوپاتولوژیک و تشخیص افتراقی: مطالعات موردی شامل اصطلاحات، شرح و چارچوب تشخیصی برای اسکوربورد در باقی مانده اسکلتی

Diverse pathological processes can produce overlapping or even indistinguishable patterns of abnormal bone formation or destruction, representing a fundamental challenge in the understanding of ancient diseases. This paper discusses increasing rigor in differential diagnosis through the paleopathological study of scurvy. First, paleopathology’s use of descriptive terminology can strive to more thoroughly incorporate international standards of anatomical terminology. Second, improved observation and description of abnormal skeletal features can help distinguish between anemia or vitamin C deficiency. Third, use of a structured rubric can assist in establishing a more systematic, replicable, and precise decision-making process in differential diagnosis. These issues are illustrated in the study of two new cases of suspected scurvy from northern Peru. From this, it appears possible that ectocranial vascular impressions may further examined as a morphological marker of scurvy in the skeleton. Also, increased paleopathological attention to pellagra is long overdue, especially as it may produce generally comparable lesions to scurvy. This paper reflexively speaks to the process of paleopathological problem solving and the epistemology of our discipline—particularly regarding the ways in which we can continuously improve description and the construction of diagnostic arguments.
