Non-neoplastic ovarian cysts include all of the following except:

The correct answer is (e) endometroid cyst.

Endometroid cysts are actually a type of neoplastic ovarian cyst, specifically a subtype of ovarian cancer.

The other options are all non-neoplastic ovarian cysts:

– (a) Follicular cyst: A fluid-filled cyst that develops from a follicle in the ovary.
– (b) Theca lutein cyst: A type of cyst that develops from the theca cells in the ovary, often associated with hormonal imbalances.
– (c) Dermoid cyst: A benign cyst that contains skin cells, hair, and other tissues.
– (d) Corpus luteum cyst: A cyst that develops from the corpus luteum, a structure that forms in the ovary after ovulation.

Non-neoplastic ovarian cysts are typically benign and may resolve on their own or require surgical removal. Neoplastic cysts, like endometroid cysts, are malignant and require treatment.

Note: It’s important to consult a healthcare professional for accurate diagnosis and treatment.
