Endometrioid tumors are associated with which type of glands?

Endometrioid tumors are indeed associated with endometrial-like glands. These tumors are typically found in the endometrium and can also occur in the ovaries. The histological features of endometrioid tumors resemble normal endometrial tissue, characterized by the presence of tubular glands and stroma that mimic the endometrial environment.

The resemblance to endometrial tissue is particularly pertinent because endometrioid carcinomas often arise in a background of endometriosis or hyperplasia, conditions linked to abnormalities in the endometrial lining. This similarity is essential for pathologists when diagnosing these tumors, as they rely heavily on the appearance of the glands under microscopic examination.

In contrast, other gland types mentioned in the options, such as ovarian-like glands, pseudostratified columnar glands, and squamous cell glands, do not describe the specific characteristics of endometrioid tumors. Each of these gland types has distinct histological features and associations with different types of tumors or tissues, emphasizing why endometrial-like glands are the correct association in this context.
