Problems of differential diagnosis in a case of bone lesions caused by myelosclerosis associated with...

The authors present a report on the case of a female patient with myelofibrosis where X-ray examinations of the bone skeleton predominantly showed such osteolytic changes which are no typical of myelosclerosis. Morphological criteria rather would have corresponded to osteitis fibrosa cystica generalisata. Laboratory examinations partially indicated primary hyperparathyroidism, this assumption could not be confirmed by other examinations. Also histological findings of repeated bone biopsies did not lead to a uniform diagnosis. Autopsy confirmed the presence of both diseases. The authors consider the synergistic effect of both diseases to be the cause for the development of those bone changes mentioned above.
