Definition
- Noun:
- A benign epithelial tumor forming a rounded mass: A 'papillary tumour' is a non-cancerous growth that originates from epithelial tissue (the tissue lining organs and surfaces) and has a distinctive, rounded, often finger-like (papillary) structure.
Usage
- The term is used in medical and pathological contexts to describe a specific type of benign growth.
- It is typically used as a countable noun (e.g., , ).
Examples
- Noun:
- The biopsy confirmed it was a benign papillary tumour.
- Papillary tumours of the bladder are often discovered during routine examinations.
Advanced Usage
- "Papillary tumour" vs. "Papillary carcinoma": It is critical to distinguish this term from 'papillary carcinoma,' which is its malignant (cancerous) counterpart. The word 'tumour' alone does not imply malignancy; the context or additional modifiers (like 'benign' or 'malignant') clarify the nature.
- The pathologist's report specified a benign papillary tumour, not a carcinoma.

Notes
- This term is highly specialized. In non-medical contexts, more general terms like 'non-cancerous growth' or 'benign lump' are used.
- The presence of a papillary tumour, while benign, may sometimes require removal if it causes symptoms or for further examination.
