What are the different types of papillary thyroid carcinoma?

What are the different types of papillary thyroid carcinoma?

The most common variants include conventional, follicular variant and tall cell variant. However, many other uncommon variants have been described including oncocytic, columnar cell, diffuse sclerosing and solid forms.

What is the most common differentiated thyroid cancer?

Follicular thyroid cancer and papillary thyroid cancer are the most common differentiated thyroid cancers. They are very often curable, especially when found early and in people younger than 50. Together, follicular and papillary thyroid cancers make up about 95% of all thyroid cancer.

What microscopic findings distinguish papillary thyroid carcinoma from other types?

Papillary thyroid carcinoma usually appears as a grossly firm mass that is irregular and not encapsulated. Microscopically, it is multifocal, and a net invasion of the lymphatics may be demonstrated. Complete or partial papillary architecture with some follicles is present.

How aggressive is papillary carcinoma?

Papillary thyroid carcinoma (PTC) is the most common thyroid malignancy, generally with an indolent clinical course. The overall 5-year relative survival rate has been reported as high as 97.5%, and only a small percentage of papillary carcinomas show aggressive clinical behavior (2).

What is papillary carcinoma classic?

Papillary carcinoma (PTC) is the most common form of well-differentiated thyroid cancer, and the most common form of thyroid cancer to result from exposure to radiation. Papillary carcinoma appears as an irregular solid or cystic mass or nodule in a normal thyroid parenchyma.

What is differentiated carcinoma?

Differentiated cancer: A cancer in which the cells are mature and look like cells in the tissue from it arose. Differentiated cancers tend to be decidedly less aggressive than undifferentiated cancers composed of immature cells.

What is a follicular variant?

The follicular variant of PTC is a unique tumor with distinct subtypes. These subtypes need to be considered in the treatment of patients with this tumor. Because of the absence of lymph node metastases in patients with EFVPTC and NFVPTC, more limited surgery may be possible in individuals with these entities.

What is encapsulated papillary carcinoma?

Encapsulated papillary carcinoma (EPC) is a rare malignant papillary breast tumor that, despite a lack of distinct myoepithelial layer, is considered an in situ carcinoma unless associated with a frank invasive component. Data regarding clinicopathologic features of rare breast tumors like EPC are especially scarce.

How is papillary thyroid carcinoma diagnosed?

The Diagnosis of Papillary Thyroid Cancer is Made by Fine Needle Aspiration (FNA) Biopsy. The diagnosis of papillary thyroid cancer is made with an ultrasound guided small sampling of cells from the thyroid gland or neck lymph nodes (or both in some instances).

What means papillary carcinoma?

What are the types of papillary cancer?

Papillary carcinoma is the most common type of thyroid cancer, accounting for approximately 80 percent of cases. Papillary carcinomas are slow-growing, differentiated cancers that develop from follicular cells and can develop in one or both lobes of the thyroid gland.

What is the survival rate of papillary cancer?

Overall papillary carcinoma carries a relatively good prognosis with a 20 year survival rate of ~90%. The 5 year survival is in the range of 95%.

What is the treatment for papillary cancer?

In its earliest stages, when the cancer cells are just beginning to affect the ducts, this disease may be referred to as infiltrating papillary carcinoma. Treatment for papillary carcinoma often consists of a combination of surgery, radiation, chemotherapy, hormone therapy and/or therapy that targets the HER2 protein.
