alopecia areata thymoma CD8+ T lymphocytes autoimmune diseases cytotoxic T-cell AA

TLDR Thymoma with alopecia areata may be linked to abnormal immune cells.

This study investigates the clinicopathological features and pathogenesis of thymoma complicated with alopecia areata (AA) through a multicenter, matched case analysis. The researchers hypothesize that the pathogenesis of thymoma with AA differs from that of thymoma with myasthenia gravis (MG), although a correlation may exist. The etiology of thymoma with AA is suggested to be linked to abnormal autoimmune CD8<sup>+</sup> T lymphocytes produced by the thymoma, which may also contribute to other cytotoxic T-cell-mediated autoimmune diseases.
