A case of myasthenia gravis with thyrotoxicosis treated by combined subtotal thyroidectomy and total thymectomy.

Thyrotoxicosis occurring in conjunction with myasthenia gravis is rare. The usual treatment consists of medical control of the thyrotoxicosis, then thymectomy and later subtotal thyroidectomy. The case reported here concerns a 19-year-old girl who had surgical treatment for both lesions on the same occasion. With proper medical preparation, modern anaesthesia and respiratory care, the surgical treatment of both lesions can be accomplished in one stage.
