Multiple osteomata from medieval Tuscany, Italy (ca. 10th-12th AD).

OBJECTIVE: To explore the possible etiology of multiple osteomata on a skull and long bones from an individual from a medieval site in Tuscany, Italy. MATERIALS: Human skeletal remains dating to the 10th-12th century AD from the parish church of S. Pietro in Pava, in the province of Siena (Tuscany, Central Italy). METHODS: Macroscopic and imaging analyses (Cone Beam Computed Tomography). RESULTS: Nine round-shaped new bone formations are observed on a female individual aged 40-50 years. The lesions have a smooth surface and range from 2.2-6 mm in diameter. CONCLUSIONS: Cone Beam Computed Tomography confirmed that the lesions were composed of compact bone. Macroscopic and radiological features suggest the presence of nonsyndromic multiple osteomata. SIGNIFICANCE: Single cranial osteomata are commonly observed in osteoarchaeological remains, but multiple osteomata are rare and might assist in our understanding of neoplastic conditions in the past. LIMITATIONS: The lack of soft tissues prevents the diagnosis of complex disorders, such as the Gardner syndrome, which is characterised by multiple osteomata and polyposis of the colon. SUGGESTIONS FOR FURTHER RESEARCH: Careful investigation and reporting of all neoplastic lesions in ancient human remains in order to increase our knowledge about the etiology in past human populations.

The privileged burial of the Pava Pieve (Siena, 8th Century AD).

RATIONALE: The 6(th) archaeological excavation campaign performed at the 'Pieve di Pava' (San Giovanni d'Asso, Siena, Italy) unearthed a privileged stone burial of a single individual (US 2378), covered by a monolithic slab and placed in front of an altar. The skeletal remains of a young male (18-20 years old), not in anatomical connection, were found at the bottom floor of a tomb (160 cm long, 40 cm large and over 70 cm deep). METHODS: A multidisciplinary study has been carried out concerning that privileged bone burial. The study combines paleopathology studies, stable isotope palaeodietary reconstruction, radiocarbon dating and archaeological analyses. RESULTS: (14) C dating of the skeleton revealed a date between 650 and 688 AD. Stable isotope analysis (δ(18) O, δ(13) C, δ(15) N) attested that he was probably a member of the local population, whose diet was rather rich in animal proteins. The paleopathological study diagnosed a case of acromesomelic dysplasia, a congenital anomaly with disproportion of the limbs. Archaeological evidence regarding the circular delimitation of the bones suggested that the skeleton was a secondary deposition, transported to the church in a sack. CONCLUSIONS: We argue that the relic was used for the re-consecration of the church, following the restoration work in the 8(th) century. We conclude that the skeleton belonged to an eminent personage (e.g., either the member of a local elite family or a saint).
