What is endometrioid adenocarcinoma of the uterus?

What is endometrioid adenocarcinoma of the uterus?

Endometrioid adenocarcinoma: This type of uterine cancer forms in the glandular cells of the uterine lining. It accounts for as much as 75 percent of all uterine cancers. Endometrioid adenocarcinoma is commonly detected early and has a high cure rate.

What is squamous cell carcinoma in uterus?

Squamous cell carcinoma (SCC) is the most common malignant tumor of the cervix, comprising 70–80% of cervical malignancies. Cervical SCC generally invades directly into the uterine wall with or without parametrial involvement.

What is Adenoacanthoma cancer?

Adenoacanthoma is malignancy of squamous cells that have differentiated from epithelial cells. It can be present in the endothelium of the uterus, mouth and large intestine.

Where does endometrial cancer usually metastasize to?

Metastatic uterine (endometrial) cancer is a type of cancer that originated in the lining of the uterus (endometrium) and has spread to distant areas of the body. In general, uterine cancer can metastasize to the rectum or bladder. Other areas where it may spread include the vagina, ovaries and fallopian tubes.

What is the most common type of endometrial carcinoma?

Most endometrial cancers are adenocarcinomas, and endometrioid cancer is the most common type of adenocarcinoma, by far. Endometrioid cancers start in gland cells and look a lot like the normal uterine lining (endometrium).

What is squamous metaplastic cells?

Squamous metaplastic cells are round to polygonal in shape with dense biphasic staining cytoplasm and round centrally located nuclei. They arise from the basal layer of glandular epithelium as a protective response to stimuli, creating the transformation zone.

Does endometrial cancer spread to brain?

Brain metastases from endometrial carcinoma are rare, however they do occur, and they are associated with an especially poor prognosis. There is evidence demonstrating improved outcomes with early diagnosis and subsequent multimodal treatment.

What is adenosquamous carcinoma of the endometrium?

An adenosquamous carcinoma of the endometrium is one which contains both malignant glandular and malignant squamous components; such tumours are considered rare in Britain but are thought to account for nearly one-third of all endometrial neoplasms in the United States.

How is adenosquamous adenocarcinoma diagnosed?

For the diagnosis of adenosquamous carcinoma, we recommend that the adenocarcinoma component be truly glandular with either definite gland formation or mucin production. Acantholysis of the squamous component (acantholytic squamous carcinoma, adenoid squamous carcinoma) with pseudogland formation should not be included as adenosquamous carcinoma.

What is the difference between adenocarcinoma and squamous cell carcinoma?

The SCC is more toward the surface, while the adenocarcinoma is deeper in the biopsy. The close proximity of the glandular and squamous components of this adenosquamous carcinoma is striking; the squamous cell component shows dyskeratosis and opaque cytoplasm , while the adenocarcinoma component shows mucinous material .

What is the difference between adenosquamous and mucoepidermoid cancer?

Adenosquamous carcinoma should not be confused with mucoepidermoid carcinoma, a malignant epithelial tumor characterized by the presence of squamoid cells, mucin secreting cells, and cells having intermediate type, identical to the same tumors encountered in the salivary glands.
