Parachordoma is a tumor that was established and described by Laskowski in 1951. It is a rare tumor, which appears adjacent to tendons, synovium, and even osseous structures. It is lobular and pseudoencapsulated. Histologically, in some ways, it is compatible with the chordomas of bone with a constant fibrous tissue component. It grows slowly and is only locally invasive. If not adequately excised, it is prone to recur, but complete surgical removal is usually possible. Its exact histogenesis remains obscure. This tumor may have some relationship to the great vesicular cells of chordoid tissue described by Schaffer as "blasige Zellen von chordoiden Gewebe" developing from special synovial cells. Ten cases collected over a period of 26 years at the Institute of Oncology in Warsaw are presented.
副脊索瘤是一种由拉斯科夫斯基在1951年确认并描述的肿瘤。它是一种罕见肿瘤，出现在肌腱、滑膜甚至骨结构附近。它呈小叶状且有假包膜。在组织学上，在某些方面，它与骨脊索瘤相符，有恒定的纤维组织成分。它生长缓慢，仅局部侵袭。如果切除不充分，容易复发，但通常可以进行完整的手术切除。其确切的组织发生仍不清楚。这种肿瘤可能与沙弗描述的由特殊滑膜细胞发育而来的脊索样组织的大泡状细胞（“chordoiden Gewebe的blasige Zellen”）有某种关系。本文展示了华沙肿瘤研究所26年间收集的10例病例。
