Definition
Meaning and Definition
A tumour arising from the endothelium, the thin layer of cells lining blood vessels, lymphatics, or body cavities.
In modern pathology, the term is considered somewhat archaic and non-specific, as tumours once classified under this broad name are now more precisely categorized (e.g., as hemangioendothelioma, lymphangioendothelioma, mesothelioma) based on their specific cellular origin and behaviour.
Dialectal Variation

Differences
No significant differences in meaning or usage. Both varieties use the same scientific term. Spelling follows standard scientific Latin roots.
Connotations
Neutral, purely technical/medical. May imply historical or less precise classification in modern contexts.
Frequency
Equally rare in both dialects, confined strictly to medical literature and historical texts.

FAQ
Frequently Asked Questions
No. The '-oma' ending indicates a tumour or growth, which can be benign or malignant. The term itself does not specify behaviour.
It is rarely used in modern precise diagnosis. Pathologists now use more specific terms like 'hemangioendothelioma' or 'mesothelioma' which give clearer information about the tumour's origin and nature.
Endothelium is the normal, healthy layer of cells lining blood and lymph vessels. Endothelioma is an abnormal growth (tumour) arising from those cells.
It can occur wherever endothelium is found, which is primarily in blood vessels and lymphatics throughout the body, as well as the lining of body cavities (e.g., pleura, peritoneum).
A tumour arising from the endothelium, the thin layer of cells lining blood vessels, lymphatics, or body cavities.
Endothelioma is usually technical/scientific (medical/pathology) in register.
