#SURGERY(AIIMS-PG)
A woman complains of generalized weakness, blurred vision, and difficulty swallowing. Physical examination shows bilateral ptosis and facial muscle weakness. A CT scan of the chest reveals a mass in the anterior mediastinum. The patient’s mass is surgically removed and is shown in the image. What is the most likely diagnosis?
A. Carcinoid tumour
B. Thymoma
C. Hodgkin's lymphoma
D. Lymphocytic lymphoma
Correct Ans: B-Thymoma
•Thymoma is a neoplasm of thymic epithelial cells, without regard to the number of lymphocytes.
•This tumor of adults is usually benign, but malignant examples occur.
•Fifteen percent of patients with myasthenia gravis have thymoma, as in this case. Conversely, one third to one half of patients with thymoma develop myasthenia gravis.
•Myasthenia gravis is not associated with the other choices, although mediastinal presentations occur.
