At current presentation, the performed magnetic resonance imaging (MRI) of the spine showed a pathologic facture at the right side of the first and second lumbar vertebral body (Figure 1) from a metastatic solid mass, as well as multiple osteolytic metastases from 7th cervical to 2nd lumbar vertebra.
Histologic photos of the mucin-poor MTSCC from the biopsy of the metastatic lesion (a and b) and from the initial right kidney tumour specimen (c and d) showing a renal cell tumour with spindle cell component, as well as tubular and papillary parts without any clear cells.
