Very lowTechnical (medical, pathological)
Definition
Meaning
A type of tumour or neoplasm that contains cysts, sac-like structures filled with fluid, air, or other material.
A benign or malignant growth, most commonly arising in ovarian tissue (ovarian cystoma), characterized by multiple cyst formations. The term is often used in histopathological classification.
Linguistics
Semantic Notes
Not to be confused with a simple 'cyst'. A cystoma specifically implies a neoplastic (tumour) process forming cysts, whereas a cyst is a general term for a fluid-filled sac which may or may not be neoplastic.

Examples
By Part of Speech
adjective
British English
- The cystomatous tissue was sent for histology.
- Cystomatous changes were observed.
American English
- The cystomatous portion of the ovary was identified.
- Cystomatous degeneration was noted.
Examples
By CEFR Level
- The scan revealed a large growth on the ovary, which the doctor called a cystoma.
- Cystomas are often discovered during routine gynaecological examinations.
- The histopathology report confirmed a benign serous cystadenoma, differentiating it from a more aggressive malignant cystoma.
- Management of a borderline ovarian cystoma requires careful consideration of fertility preservation and oncological risk.
Learning
Memory Aids
Mnemonic
Think of CYST (a fluid-filled sac) + -OMA (a tumour). So, a cystoma is a tumour that makes cysts.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate simply as 'киста'. In Russian medical terminology, 'кистома' is a direct equivalent. A simple 'cyst' is 'киста'. The '-ома' ending in both languages indicates a tumour.
Common Mistakes
- Using 'cystoma' interchangeably with 'cyst'.
- Pronouncing it as /saɪˈstoʊmə/ (with a long 'i').
- Assuming it is always malignant.

FAQ
Frequently Asked Questions
No. Cystomas can be benign (e.g., cystadenoma), borderline, or malignant (e.g., cystadenocarcinoma). The term describes the structure, not the behaviour.
The ovary is the most common site, leading to the frequent term 'ovarian cystoma'.
A cyst is a general term for a closed sac. A cystoma specifically refers to a tumour (neoplasm) that has a cystic structure. All cystomas are cystic tumours, but not all cysts are cystomas.
It is unlikely. A GP might say 'complex cyst' or 'cystic growth'. 'Cystoma' is a term primarily used by pathologists, gynaecologists, and oncologists after histological examination.
