title: [Amyloid tumor of bone].
abstract: An osseous plasmocytoma was masked by an excessive tumor-like deposit of amyloid to such an extent that the primary disease was only diagnosed after histological examination of autopsy material from a 62 year old woman. The 20 cm in diameter tumor originated from the manubrium sterni. Other tumors were found in the ribs, right clavicle, thoracic and lumbal spine and in the left femur. A massive layer of amyloid was found in these tumors by microscopy. Plasma cells infiltrated the area between the amyloid plaques and the macroscopically tumor-free vertebral bodies. All other organs were free from amyloid.
