Introduction:
One of the major disabling health conditions among elderly is back pain due to degenerative diseases. Less than 1% of spine disorders are caused by malignancies. Among the rare primary vertebral neoplasms the multiple myeloma and the plasmacytoma account for 26% of these cases.
Presentation of case:
We are reporting a case of 64 year-old woman, who suffered from progressive upper back pain and intermittent neurological symptoms including lower limb weakness and voiding disorder under axial loading. Her medical history includes a Lynch syndrome (LS). Computed tomography (CT) and magnetic resonance imaging (MRI) detected a single malignant osteolytic process of the spine involving T5. Urgent surgery with laminectomy intralesional tumor removal and posterior stabilization (Th4-Th6) due to unstable pathologic fracture with spinal cord compression was conducted after interdisciplinary decision. Histopathological examination of the tumor revealed a solitary plasmacytoma.
Discussion:
To our knowledge this is the first case report of a solitary plasmacytoma of the bone (SPB) that arise in a patient who suffers from LS. Similar DNA mismatch repair malfunction is existent in LS and SPB. Hence, a hereditary correlation might be imaginable.
Conclusion:
When detecting a lytic spinal tumor in a patient who suffers from LS a SPB should be taken under consideration.
