A tumor derived from epithelial tissue (the tissue lining organs and surfaces of the body).
A malignant or benign tumor arising from the epithelium, often referring to specific types such as squamous cell carcinoma or basal cell carcinoma in dermatological and oncological contexts.
Linguistics
Semantic Notes
This is a highly technical term from oncology and pathology. It refers to the origin of the tumor (epithelium) and not necessarily its behaviour (malignancy). Some types are malignant, others can be benign. It is a subclassification within oncology.

Translation Traps (for Russian speakers)
- Avoid direct calque from 'эпителиома'. Ensure correct medical register. Do not confuse with broader 'рак' (cancer) or 'опухоль' (tumor).
Common Mistakes
- Pronouncing it as 'epi-theel-ee-oh-ma' (incorrect stress).
- Using it in non-medical contexts.
- Confusing it with 'epithelium' (the tissue itself).

FAQ
Frequently Asked Questions
No. The term describes the origin (epithelium), not the behaviour. Some epitheliomas are benign (e.g., calcifying epithelioma of Malherbe), while others are malignant carcinomas.
'Epithelioma' is a broader histological term for any tumor of epithelial origin. 'Carcinoma' is a subset meaning a *malignant* epithelial tumor. In practice, 'carcinoma' is more common for malignant cases.
Typically, no. A GP or dermatologist would use more accessible terms like 'skin cancer', 'basal cell carcinoma', or 'growth' to ensure patient understanding.
No verb form exists. The adjectival form is 'epitheliomatous' (e.g., an epitheliomatous growth).
