Metastatic cancer in a medieval skeleton from the Principality of Liechtenstein.

We present a presumptive case of metastatic carcinoma in an individual from the 11^th/12^th century CE from Vaduz, Principality of Liechtenstein. The skeleton exhibits extensive new bone formation in the axial skeleton and the proximal humerus and femur. Radiological examinations revealed further sclerotic lesions in the clavicles, the manubrium, the sternum, the femoral diaphysis, and possibly the frontal. The pelvic bones and the sacrum, as well as the spine, are the most heavily affected skeletal regions. The newly formed bone in some lesions has a "sun-burst" appearance. The sex and age at death of the individual, the distribution and the osteoblastic nature of the lesions suggest that prostate carcinoma is the most likely primary tumor.
