(+info)Adenomyoepithelioma is a rare, usually benign tumor of the breast that contains both glandular (epithelial) and supportive tissue (myoepithelial) components. It can occur in the salivary glands as well. These tumors are typically slow-growing and may present as a painless mass or lump. In some cases, they can become malignant and aggressive, leading to local invasion and metastasis. Treatment usually involves surgical excision of the tumor.
Myoepithelioma is a very rare, benign (non-cancerous) tumor that arises from the myoepithelial cells, which are found in various glands throughout the body, including salivary glands, sweat glands, and mammary glands. These tumors typically appear as slow-growing, painless masses. While they are usually benign, some myoepitheliomas can become malignant (cancerous) and invasive, leading to more serious health concerns. Treatment for myoepithelioma typically involves surgical removal of the tumor.
Adenomyoma is a benign (non-cancerous) growth that occurs when the glands and muscle tissue from the lining of the uterus (endometrium) become embedded in the muscular wall of the uterus (myometrium). This condition most commonly affects women in their 40s and 50s, and it can cause symptoms such as heavy menstrual bleeding, painful periods, and pelvic pain or discomfort.
The term "adenomyoma" is derived from two words: "adeno," which means gland, and "myoma," which refers to a benign muscle tumor. Therefore, an adenomyoma can be thought of as a benign growth that contains both glandular tissue and muscle tissue.
Adenomyomas are typically found in the lower part of the uterus, near the cervix, and they can vary in size from small nodules to larger masses. In some cases, adenomyomas may cause no symptoms at all, while in other cases, they can lead to significant discomfort and pain.
The exact cause of adenomyoma is not fully understood, but it is thought to be related to hormonal factors, as well as trauma or injury to the uterus. Treatment options for adenomyoma may include medication to manage symptoms, such as pain relievers or hormone therapy, or surgical intervention, such as a hysterectomy (removal of the uterus).
Breast neoplasms refer to abnormal growths in the breast tissue that can be benign or malignant. Benign breast neoplasms are non-cancerous tumors or growths, while malignant breast neoplasms are cancerous tumors that can invade surrounding tissues and spread to other parts of the body.
Breast neoplasms can arise from different types of cells in the breast, including milk ducts, milk sacs (lobules), or connective tissue. The most common type of breast cancer is ductal carcinoma, which starts in the milk ducts and can spread to other parts of the breast and nearby structures.
Breast neoplasms are usually detected through screening methods such as mammography, ultrasound, or MRI, or through self-examination or clinical examination. Treatment options for breast neoplasms depend on several factors, including the type and stage of the tumor, the patient's age and overall health, and personal preferences. Treatment may include surgery, radiation therapy, chemotherapy, hormone therapy, or targeted therapy.

Breast2
- An adenomyoepithelioma of the breast is a rare tumour in the breast composed of glandular elements (adeno-) and myoepithelial cells. (wikipedia.org)
- In addition, a variety of other rare breast lesions reveals a papillary architecture such as tall cell carcinoma with reversed polarity (TCCRP) and mucinous cystadenocarcinoma, adenomyoepithelioma, and secretory carcinoma. (nih.gov)

- Adenomyoepithelioma usually composed of many small round ovoid and tubular glands, lined by bland luminal and myoepithelial cells, later should be prominent and striking in appearance. (pathoclinics.com)
- Myoepithelial markers are usually focally present and not extensive as seen in adenomyoepithelioma. (pathoclinics.com)
- But, rest of the areas and high number of myoepithelial cells, highlighted by calponin and P63 favors adenomyoepithelioma. (pathoclinics.com)
- Some features like circumscribed mass and lobules of marked proliferation of closely lacked regular round ducts and tubules with open lumina and very little stroma may resembles to tubular adenoma , but tubular adenoma usually lined by single layer of myoepithelial cells while adenomyoepithelioma (tubular variant) show prominent myoepithelial cells proliferation.

Pleomorphic adenoma1
- Focal or rare presence of chondroid metaplasia resembles to salivary gland pleomorphic adenoma, considered as a variants of adenomyoepithelioma. (pathoclinics.com)

- Adenoid cystic carcinoma can show areas of tubular component of adenomyoepithelioma and adjacent cribriform pattern. (pathoclinics.com)
Carcinoma1
- Atypical features like high-grade nuclear atypia, increased mitotic activity (more than three mitosis per 10 HPF), and focally infiltrative margins should be considered strongly for carcinoma in a background of adenomyoepithelioma. (pathoclinics.com)
