THYMUS - Thymoma

Description of Specimen
The specimen is a nodular mass in which there are a number of minute cysts and an extensive area of haemorrhage. The outer surface is nodular.
This woman presented at the age of 41 with a three-month history of periodic recurring pain across the shoulders and upper limbs with weakness. Some two months before presentation she noticed slurring of the speech which improved after rest. Over the few days prior to presentation she had some difficulty in swallowing and difficulty in sitting up easily. The Tensilon test was positive and on the basis of this and the other findings a diagnosis of myasthenia gravis was made. Subsequently the thymic mass was resected.
