RESUMO
OBJECTIVE: This study presents a new case of solitary osteochondroma (SOC) identified on the proximal tibia of a 4th-century BCE individual from Pontecagnano (Salerno, Italy) with an aim to contribute to differential diagnosis of bone tumors in archeological contexts. MATERIALS: Paleopathological assessment of a male individual with an estimated age-at death of 45.9-62.9 years brought to light during the archaeological excavations in the funerary sector of 'Sica de Concillis' within the necropolis of Pontecagnano. METHODS: Macroscopic and radiographic analyses were performed for diagnostic purposes. RESULTS: The proximal portion of the right tibia exhibited a large exophytic bone formation extending from the anteromedial to the posteromedial portion of the diaphysis. The x-ray confirmed the lesion being characterized by regular trabecular bone tissue with cortico-medullary continuity. CONCLUSIONS: The lesion observed is diagnostic of sessile SOC, a neoplasm that must have had aesthetic and, possibly, neurovascular complications due to its large size. SIGNIFICANCE: By offering a detailed description of a case of tibial osteochondroma and discussing the possible complications the individual might have experienced during life, this study highlights the role and importance of benign bone tumors in paleo-oncology. LIMITATIONS: Histological analysis was not carried out in order to preserve the integrity of the affected tibia. SUGGESTIONS FOR FURTHER RESEARCH: More attention should be devoted to benign tumors in paleopathology as their occurrence and manifestations in the past will lead to a better understanding of their impacts on the quality of life of affected individuals and to greater knowledge of their natural history.
