Note: Endometrioid adenoma is a rare and malignant tumor variant of endometrial adenocarcinoma, characterized by adenoma-malignum-like features. Its development is influenced by hormonal imbalances, genetic mutations, and environmental factors.
Adenoma-Malignum-Like
Endometrioid adenoma, also known as “adenoma-malignum-like,” resembles adenoma malignum, a rare form of cervical cancer, histologically. When examined under a microscope, it is observed that the glandular cells deeply invade the myometrium, which is the muscular layer of the uterus. This invasive growth pattern is specific to adenoma malignum and indicates an aggressive behavior of endometrioid adenoma. It can also result in cervical stromal involvement, which adds complexity to the diagnosis and management of the condition.
Rare Variant
Endometrioid adenoma is a rare variant of endometrial adenocarcinoma, with only 58 cases reported in the literature. This rarity poses challenges in both diagnosis and management of the condition. Moreover, the limited number of reported cases indicates that our understanding of this condition is still evolving. Therefore, collaborative research efforts and further studies are crucial for uncovering more information about the pathogenesis, clinical presentation, and treatment options for endometrioid adenoma.

Endometrial Endometrioid Adenocarcinoma
Endometrioid adenoma is a type of endometrial cancer called endometrial endometrioid adenocarcinoma. This form of cancer is the most common one affecting the endometrium, which is the lining of the uterus. It is characterized by the presence of abnormal glandular cells.
The main difference between endometrioid adenoma and endometrial endometrioid adenocarcinoma lies in the depth of invasion of these glandular cells into the myometrium, which is the muscular layer of the uterus. When the glandular cells invade deeply into the myometrium, it indicates a more aggressive and advanced stage of the disease.
Notable points:
- Endometrioid adenoma is a type of endometrial cancer.
- Endometrial endometrioid adenocarcinoma is the most common type of endometrial cancer.
- It arises from the lining of the uterus and is characterized by abnormal glandular cells.
- The depth of invasion into the myometrium differentiates endometrial endometrioid adenocarcinoma from endometrioid adenoma.
- Deeper invasion indicates a more aggressive form of the disease.
“The distinction between endometrioid adenoma and endometrial endometrioid adenocarcinoma lies in the deep invasion of glandular cells into the myometrium, distinguishing it as a more aggressive form of the disease.”
Microscopic Examination
Microscopic examination is a crucial diagnostic tool for endometrioid adenoma. The examination reveals:
- Deep invasion of glandular cells into the myometrium
- Cervical stromal involvement
The malignant cells may exhibit a characteristic “adenoma malignum-like” pattern of invasion, further complicating the diagnosis.
It is essential for pathologists to carefully evaluate the histological features to distinguish endometrioid adenoma from other similar conditions, such as benign-looking endometrial glands found in the myometrium.
Deep Invasion Of Glandular Cells
The deep invasion of glandular cells into the myometrium is a hallmark feature of endometrioid adenoma. This invasion indicates a more aggressive behavior and a higher stage of the disease, typically classified as pT2 stage. The invasion not only affects the uterine lining but also extends to the surrounding myometrium, increasing the risk of tumor spread and metastasis. Prognosis in cases of deep invasion is generally poorer compared to cases with superficial involvement, highlighting the importance of early detection and intervention.
Myometrium
The myometrium is a crucial anatomical structure of the uterus composed of smooth muscle tissue. In endometrioid adenoma, the invasive growth of glandular cells infiltrates the myometrium, potentially compromising its integrity and functionality. The degree of myometrial involvement is an important factor in determining the stage of the disease and guiding treatment decisions. In cases where the myometrium is extensively invaded by malignant cells, more aggressive treatments, such as surgery and adjuvant therapies, may be necessary to achieve optimal outcomes.
Pt2 Stage
The deep invasion of glandular cells into the myometrium classifies endometrioid adenoma as pT2 stage, according to the International Federation of Gynecology and Obstetrics (FIGO) staging system. This staging system is crucial for determining the extent of the disease and guiding treatment decisions. The pT2 stage indicates a more advanced disease that requires comprehensive management strategies, including surgical interventions, radiotherapy, and chemotherapy, to improve patient outcomes.
Cervical Stromal Involvement
Cervical stromal involvement is a common occurrence in cases of endometrioid adenoma. The glandular cells can invade the cervix, making diagnosis and treatment planning more complex. Additional surgical procedures may be necessary to fully remove the malignant tissue and decrease the chances of recurrence. Careful evaluation of the extent of cervical stromal involvement is essential for healthcare professionals in order to develop personalized treatment strategies for each patient.
- Cervical stromal involvement is frequently seen in endometrioid adenoma cases.
- The invasive growth of glandular cells can extend into the cervix, complicating the diagnosis and treatment planning.
- Additional surgical procedures may be required to completely remove malignant tissue and reduce the risk of recurrence.
- Healthcare professionals should evaluate the extent of cervical stromal involvement to create individualized treatment strategies for each patient.
History Of Endometrial Adenocarcinoma
Endometrioid adenoma is frequently linked to a prior diagnosis of endometrial adenocarcinoma. Although the precise connection between these two conditions is not entirely clear, it is hypothesized that endometrioid adenoma may develop as a result of the progression or recurrence of endometrial adenocarcinoma. Therefore, individuals with a history of endometrial adenocarcinoma should be diligently monitored for any indications or symptoms of endometrioid adenoma to ensure early detection and appropriate intervention. Implementing regular follow-up visits and comprehensive surveillance protocols is crucial in enhancing patient outcomes and minimizing the risk of disease advancement.
To summarize the key points:
- Endometrioid adenoma is associated with a history of endometrial adenocarcinoma.
- It can arise as a progression or recurrence of endometrial adenocarcinoma.
- Patients with a prior diagnosis of endometrial adenocarcinoma should be closely monitored for signs and symptoms of endometrioid adenoma.
- Early detection and timely intervention are essential.
- Regular follow-up visits and comprehensive surveillance can improve patient outcomes and reduce the risk of disease progression.
“Patients with a history of endometrial adenocarcinoma should be closely monitored for signs and symptoms of endometrioid adenoma to ensure early detection and appropriate intervention.”

You may need to know these questions about endometrioid adenoma
What is the meaning of endometrioid adenoma?
Endometrioid adenoma is a specific type of endometrioid tumor characterized by the presence of glandular structures resembling the endometrium or endometrial carcinoma. This type of tumor often occurs in the ovary and is histologically well-differentiated. It is important to note that endometrioid adenoma may also exhibit focal squamous differentiation in about one-third of cases. Understanding the histopathology of endometrioid adenoma in the ovary is crucial in identifying and diagnosing this tumor subtype.
Is endometrioid adenocarcinoma aggressive?
Endometrioid adenocarcinoma can exhibit varying levels of aggressiveness, and dedifferentiated endometrioid adenocarcinoma (DEAC) is recognized as a particularly aggressive subtype within this category. DEAC is infrequent but characterized by a higher level of aggressiveness when compared to high-grade endometrioid carcinoma. It is crucial to distinguish between these two types to ensure patients receive the most suitable treatment for their condition. Accurate identification and understanding of the aggressiveness of DEAC are vital factors in providing patients with optimal care and improving their prognosis.
Is endometrioid an ovarian cancer?
No, endometrioid is not a type of ovarian cancer. While ovarian endometrioid carcinomas (OECs) are a subtype of ovarian carcinoma, they only account for 10% of cases. The majority of ovarian carcinomas are high-grade serous carcinomas, which have a poor prognosis. Unlike high-grade serous carcinomas, most OECs are low-grade and have a good prognosis, similar to endometrial serous carcinomas.
What is the survival rate for endometrioid adenocarcinoma?
The survival rate for endometrioid adenocarcinoma can vary depending on the stage of the disease. According to the provided background information, the 5-year relative survival rates range from 90% for women with stage 0, 88% for women with stage IA, to 75% for women with stage IB. These numbers indicate a generally favorable prognosis for women diagnosed with endometrioid adenocarcinoma, especially in the earlier stages of the disease. However, it is essential to note that individual cases may differ, and factors such as age, overall health, and response to treatment can also impact the survival rate.
