Concomitant Thymic Carcinoma With Cervical and Supraclavicular Node Metastases and Thyroid Carcinoma: Report of a Case and Literature Review

摘要

Thyroid and thymus neoplasms are comparatively rare. In this case report, the concomitant diagnosis of these two rare neoplasms in the same patient is presented. An increased incidence of second malignancies in patients with thymic neoplasms has been found in several case series but is still debated by others. It appears that this increased risk for second malignancies in patients with thymic neoplasms extends to a wide range of localizations and concerns neoplasms diagnosed before, concomitantly with and after thymic neoplasms. A pathogenic hypothesis of decreased immunologic surveillance is proposed and implications the association has for patient care are discussed.doi:10.4021/jmc568w
