KROK 1 2010 – Question 160 · KROK (Medicine) · Pathomorphology
Examination of a 66 year old patient revealed a lytic tumour in the locus of pathological rib fracture. Histologically this tumour consists of atypical plasmoblasts. Further examination revealed osteoporosis in the bones of vertebral column and pelvis. These changes are typical for:
- A. Neuroblastoma
- B. Metastatic lung cancer
- C. Ewing’s osteosarcoma
- D. Tuberculous osteomyelitis
- E. Myelomatosis
Hint
Think about what a tumour of plasmoblasts does to bone through the factors it secretes, and whether a single primary lesion or a multifocal disease fits the findings.
