What is the difference between thymoma and thymic carcinoma?

Thymoma also differs from thymic carcinoma with regard to spread (metastasis). Thymoma cells tend to grow very slowly, and it's rare for them to spread to other parts of the body. Thymic carcinoma cells, on the other hand, grow rapidly and tend to spread throughout the body.

Who subtypes thymoma?

Thymomas are classified as type A thymoma (including an atypical variant), AB thymoma, type B thymoma (separated into B1, B2, and B3 thymomas), micronodular thymoma with lymphoid stroma, and metaplastic thymoma by histologic features and, rarely, immunohistochemistry, such as immature T cell content.

Are most thymomas benign?

Most thymomas have the potential to behave like a cancer and spread beyond the thymus, but many appear to behave in a benign fashion and are noninvasive. Less commonly, it appears to have spread beyond the thymus. People sometimes refer to such an invasive thymoma as malignant thymoma.

How many patients were diagnosed with B2 thymoma?

A total of 252 patients underwent a surgical resection for thymoma between January 1995 and January 2010 in Zhejiang Cancer Hospital. In this period, 42 patients were diagnosed as type B2. The stage of thymoma was classified based on the Masaoka staging system. All patients had been pathologically confirmed as having type B2 thymoma (WHO histologic classification) by surgery or needle biopsy. Recurrence or metastases were confirmed using chest computed tomography, as well as ultrasound and/or computed tomography of the abdomen. The study was approved by the ethics committee of Zhejiang Cancer Hospital.

What is the prevalence of thymoma?

Thymoma has a prevalence of 0.1 to 0.4/100,000 and accounts for less than 1% of all malignant tumors [ 1 ]. The B2 type of thymoma is defined as a tumor in which the neoplastic epithelial component appears as scattered plump cells with vesicular nuclei and distinct nucleoli among a heavy population of lymphocytes by the World Health Organization (WHO) classification [ 2 ].
