A curious rarity of the thymus gland: the microscopic thymoma
Abstract
In 1976, Rosai & Levine (1) opened a novel and interesting niche in the variegated field of the morphology of thymus gland in myasthenia gravis (MG). These authors firstly described a microscopic lesion having the histological features of a thymoma, occasionally observed in thymus gland removed during cardiac operations.
