Abstract
Thymic pathologies such as lymphoid follicular hyperplasia or thymoma are seen in 75% of myasthenia gravis subjects. Microscopic thymoma is a lesion that is seen in 15% of myasthenia gravis patients. The World Health Organization defines microscopic thymoma as a “ usually multifocal epithelial proliferation <1 mm in diameter”. Microthymoma, in other words microscopic-sized thymoma, should be considered in the differential diagnosis of microscopic timoma. We present the case of a 28-year-old male patient followed-up for myasthenia gravis and diagnosed with “microscopic thymoma” following thymectomy.
Key words: Thymus, microscopic thymoma, thymoma, myasthenia gravis.
