  Fig. 1. Histologic findings. First biopsy of case 1 (A) and case 2 (B). Microscopic finding of first biopsy reveals adenocarcinoma showing glandular differentiation. Rebiopsy of case 1 (C) and case 2 (D). Microscopic finding shows sarcomatous tumor cells producing osteoid (asterisks).

• 

  Fig. 2. Radiologic findings. Case 1 (A). Pelvic magnetic resonance imaging demonstrates left iliac metastases with ossification at the extraosseous soft tissue (arrow). Case 2 (B). Computed tomography reveals T2 and T5 vertebral bodies metastases.
