Cervical Endometrioid Adenocarcinoma: A Rare and Challenging Diagnosis

Cervical endometrioid adenocarcinoma is a rare subtype of cervical cancer that originates from the glandular cells of the cervix. It is also known as endometrioid carcinoma of the cervix.

Characteristics and Features

• Cervical endometrioid adenocarcinoma is a type of adenocarcinoma, which means it arises from glandular cells.
• It is a rare subtype of cervical cancer, accounting for only a small percentage of all cervical cancers.
• The tumor morphology in the cervix is similar to that found in the endometrium (the lining of the uterus).
• Cervical involvement of endometrial carcinoma can be detected through a cervical smear.

Distinguishing Features

• Cervical endometrioid adenocarcinoma can be difficult to distinguish from endometrial adenocarcinoma, particularly in large bulky cases.
• The secretory pattern in some well-differentiated endometrioid carcinomas may resemble early secretory endometrium due to supranuclear and subnuclear vacuolization.

Prognosis and Treatment

• Cervical involvement of endometrial adenocarcinoma is associated with decreased survival rates compared to non-invasive cases.
• Treatment often consists of a hysterectomy to remove the uterus, as well as other surgical or medical interventions.

The differential diagnosis of cervical endometrioid adenocarcinoma involves distinguishing it from other types of adenocarcinomas that may present similarly.

Key Considerations

• Endometrial Endometrioid Adenocarcinoma: This is a common entity that can extend into the cervix or primarily involve the lower uterine segment/upper vagina, making differential diagnosis challenging [13].
• Usual-Type Endocervical Adenocarcinoma: This type of adenocarcinoma can also present with an endometrioid morphology and may be difficult to distinguish from cervical endometrioid adenocarcinoma. Investigation of the HPV status of the tumor can help confirm the diagnosis [11].
• Metastatic Mucinous Carcinoma from the Colon: This is another differential diagnosis that should be considered, particularly in cases where goblet cells are present [15].

Other Considerations

• Clear Cell Adenocarcinoma: While less common, clear cell adenocarcinoma can also be a consideration in the differential diagnosis of cervical endometrioid adenocarcinoma.
• Serous-Like Carcinoma and High-Grade Serous Carcinoma: These entities may also present with complex architecture and should be considered in the differential diagnosis.

Importance of Histologic Examination

A detailed histologic examination, including investigation of the HPV status of the tumor, is essential to accurately diagnose cervical endometrioid adenocarcinoma and distinguish it from other types of adenocarcinomas.
